Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document management apparatus for storing and managing, for example, a WWW page browsed by a WWW browser, a document created by a word processor, an editor, spreadsheet software and other applications.

[0002]

2. Description of the Related Art With the spread of PCs and word processors in recent years, documents in offices have been digitized. In addition, the use of e-mail has rapidly increased due to the development of the Internet and intranet, and the above-mentioned digitization has been further accelerated. As a result, many offices are flooded with a large amount of electronic data, and the importance of efficiently organizing and managing these is increasing.

For this reason, various document management apparatuses for efficiently managing these electronic documents have been developed. One device has a feature in a method of registering a document, and a file can be registered in a database simply by dragging and dropping a file on an icon on a desktop. Another device has a feature in a method of searching for a document. For example, a document can be searched in a natural language that is used everyday, such as “materials distributed at a meeting yesterday”. In addition, a certain device specializing in electronic mail automatically takes in the received e-mail, sorts the received e-mail into folders for each sender, and can later perform a search using a full-text search or the like. Recently, a device having these characteristics has been developed.

As described above, various devices have been conventionally developed as a document management device. The registration function requires a user to directly perform a registration operation, or only a specific document such as an electronic mail. The system could be registered automatically.

[0005] The Internet and WWW (World W
With the development of ide Web, the rate of obtaining information through a WWW browser is increasing, and the importance of managing WWW pages is increasing. U registered in advance
Software has been developed that automatically crawls WEB sites according to RL and collects copies of WWW pages. However, it does not register the pages you have viewed.

Further, there is an apparatus having a function of registering a cache of a WWW page left on a disk by a WWW browser. If you use this function, you can register only the page you saw in the database, but there is a problem that you can not register if the cache is cleared. In addition, since the number of caches becomes enormous in a short time, it is necessary to perform appropriate filtering before registration. However, no device having such a filtering function has appeared so far.

[0007]

As described above, the registration function of the conventional document management apparatus is provided with an automatic registration function for all those created, edited, and browsed by the user himself, that is, all those directly operated by the user. Instead, the user must directly perform a registration operation, or only a specific document such as the above-mentioned mail is targeted.

[0008] Further, there has been no device having a function of automatically registering, on a huge amount of information obtained through a WWW browser, an object that has been narrowed down by filtering from pages actually viewed by the user.

In view of the above problems, the present invention makes it easy to manage documents by automatically creating index information that allows a user himself / herself to create, edit, or browse a document that has actually been created, edited, or viewed later. It is an object of the present invention to provide a document management method that can be performed and a document management device using the same.

Further, according to the present invention, from among a huge amount of documents obtained through a WWW browser, only those hitting preset profile information are automatically copied to a local machine at the time of browsing, and an index for the copied data is further obtained. By automatically creating information,
It is an object of the present invention to provide a document management method capable of easily managing documents and a document management device using the same.

[0011]

According to the document management method of the present invention, a timing for creating index information for searching a stored document is set, and attribute information relating to the document is set according to the set timing. By extracting and creating index information and storing it in association with the document, the user himself / herself automatically creates index information for a document actually created, edited, or browsed, and later uses this index information. To easily search for documents.

Further, the document management method of the present invention searches a browsed document for the document based on attribute information extracted from the browsed document and profile information defining the attribute of the document to be selected. By selecting a document for which index information is to be created, creating the index information from attribute information extracted from the selected document, and storing the selected document and the index information in association with each other. From among a huge number of documents (WWW pages) obtained through a WWW browser, only those that hit the preset profile information are automatically stored at the time of browsing, and index information for the stored data is automatically created. Later, the stored WWW page can be easily searched using the index information.

The document management apparatus according to the present invention includes a timing setting means for setting a timing for creating index information for searching for a stored document, and extracting attribute information on the document at the set timing by extracting attribute information on the document. By providing a creation unit for creating information and a storage unit for storing the index information in association with the document, the user himself / herself automatically creates index information for a document actually created, edited, or viewed. Then, the document can be easily searched later using the index information.

[0014] Preferably, the apparatus further comprises a search means for searching for a document based on the index information, and a presentation means for presenting a search result of the search means together with at least the index information.

The document management apparatus according to the present invention further comprises: an extracting unit for extracting attribute information from the viewed document; and the extracted attribute information and profile information defining an attribute of a document to be selected. Selecting means for selecting a document for creating index information for searching the document among the viewed documents; creating means for creating the index information from attribute information extracted from the selected document; Storage means for storing the associated document and the index information in association with each other.
Of the huge number of documents (WWW pages) obtained through a WW browser, only those that hit the preset profile information are automatically stored when browsing, and index information for the stored data is automatically created. Later, the WW stored using this index information
W page can be easily searched. It is also possible to generate effective index information for information that is updated daily, such as a WWW page.

Preferably, the apparatus further comprises a search means for searching for a document based on the index information, and a presentation means for presenting at least the search result of the search means together with the index information. For example, by presenting in a tree format and a table format and displaying them in cooperation with each other, the user becomes more convenient when searching for a desired document from a search result.

Preferably, the apparatus further comprises a search means for searching for a document having the specified attribute information based on the profile information. In addition, the document and index information stored in the storage unit further include a document having attribute information designated based on the profile information and a deletion unit for deleting the index information. As a result, documents can be searched and deleted more rationally, and convenience in document management is improved.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) FIG. 1 shows a configuration example of a document management apparatus according to a first embodiment of the present invention.

The browsing unit 1 browses, creates, and edits digitized documents such as text documents and HTML documents stored in the file storage unit 8.
The browsing unit 1 is configured by an existing application such as an editor or a word processor in addition to the one created exclusively for the document management apparatus.

The registration operation setting unit 2 is for setting the operation of the browsing unit 1 which is a timing for starting the creation of index information for documents created, edited, and browsed by the browsing unit 1.

The registration operation definition table 3 is for recording and storing the settings made in the registration operation setting section 2, and the registration control section 4 performs registration control with reference to the registration operation definition table 3. ing. For example, in the case of MS-Windows, the registration operation definition table 3 uses a registry or an INI file. Similar systems are used in other systems, such as UNIX and MacOS.

When the registration control unit 4 detects the operation of the browsing unit 1 based on the set value of the registration operation definition table 3, it controls the keyword extraction unit 5, the attribute acquisition unit 6, and the index information creation unit 7 to control the index information. Create and register.

The keyword extracting unit 5 extracts a keyword from a document that has been browsed, created, or edited by the browsing unit 1. A keyword extraction method may be an existing one.For example, a text part in a document is morphologically analyzed, words such as nouns are extracted, and the frequency of occurrence of the noun is obtained. It may be a keyword. Alternatively, a document may be matched with a dictionary using a dictionary in which words that can be keywords for each field are registered in advance, and the matched word may be used as a keyword of the document.

The attribute acquiring unit 6 browses, creates,
The attribute other than the keyword of the document being edited is acquired.

The index information creating unit 7 creates index information for a document browsed or created and edited by the browsing unit 1 based on the keywords and various attribute values obtained by the keyword extracting unit 5 and the attribute acquiring unit 6.

The file storage unit 8 stores various files of a document, and is composed of a hard disk and various removable media.

The index database 9 stores and manages the index information created by the index information creating unit 7, and the search unit 10 performs a search based on the index information.

The search unit 10 searches the index database 9 based on a search request from the user, and transmits the result to the search result presentation unit 14.

The search result presenting section 14 is provided in the form of a tabular presenting section 1.
1, a tree format presenting unit 12 and a cooperation control unit 13 for presenting the search results of the search unit 10 to the user.

The tabular presentation unit 11 presents the search results in a one-line table for each search result. The results are presented in a manner that makes it easy to list the results based on similarities or keywords.

The tree-form presenting section 12 presents a directory structure in a tree form in order to easily show where the retrieved document file is stored in the file storage section 8.

The coordination control unit 13 performs control for coordinating both displays according to the user's document selection operation performed on the tabular presentation unit 11 and the tree presentation unit 12.

The user interface unit 15 includes an output device such as a display device, and various input devices such as a keyboard and a mouse. The user inputs various instructions, inputs a search formula, and displays a document. And the display of document search results.

Next, registration timing and its setting by the document management apparatus of FIG. 1 will be described. Note that registration here refers to creating index information for a document file already stored in the file storage unit 8 and registering the index information in an index database. This is called “document registration”. Sometimes.

Viewing unit 1 set as registration timing
For example, there are two operations, that is, closing the browsing unit 1 or closing the browsing window and saving a file by user operation. The user can select one or both of these two through the registration operation setting unit 2. Good. For example, if only “A” is set, all of the documents that have been browsed or edited are registered. If only is set, only the edited document is registered. When the browsing unit 1 has an automatic save function, registration at the time of automatic save can be added as an option. When both are set, all of the browsed documents and edited documents are registered in the same manner as the setting only, but the registration timing at the time of editing is different from the setting only. Registration at the time of saving is the basis, and if the processing is terminated without editing after saving, the registration at the time of termination is not performed.

The setting contents are written in the registration operation definition table 3 and are referred to by the registration control unit 4.

The above is the procedure for setting the registration timing.

FIG. 2 is a diagram showing the structure of index information used in the document management apparatus. Attribute information (eg, ID number, file name, path name, file type, media type, date and time of creation) related to the document file is shown. ,title,
Author) and a keyword extracted from the document, and one piece of index information is created for one document.

The ID numbers are issued in the order of creation of the index information in the order of “1,” “2,” “3,”..., And are unique integer value data in all the index information stored in the index database 9. is there.

The file name is character string data representing the file name of the document file on the file storage unit 8.

The path name is character string data representing the path name of the document file on the file storage unit 8.

The method of expressing the file name and the path name depends on the OS on which the document management device operates. For example, MS-Wi
In the case of Windows, "Document.tx"
t ”,“ c: \ home \ My Document \ d
document. txt ”or other character string data.

The file type is, as shown in FIG. 3, pre-defined numerical data representing the file type.
For example, it depends on the OS on which the document management apparatus operates, the application to be used, and the type of the target file. For example, MS-Office on MS-Windows
In the case of a file of each application e, a rich text format (RTF) file, and a standard text file, the definition values shown in FIG. 3 are used.

The type of media is, as shown in FIG. 4, predefined numerical data indicating the type of storage location of a file. For example, the type of media depends on the OS on which the document management device operates. For example, in the case of MS-Windows, FIG.
Use the defined values as shown in.

The creation date and time is date type data indicating the date and time when the document file was created or the last update date and time.

The title is character string data representing the title of the document file.

The creator is character string data representing the creator of the document file.

The keyword is list-type data whose value is the keyword extracted from the text part of the document by the keyword extraction unit 5.

Next, with reference to a flowchart shown in FIG. 5, the processing of creating and registering index information by the registration control unit 4 will be described.

The registration control unit 4 monitors the execution of the operation set in the registration operation definition table 3 by the browsing unit 1, that is, the saving of the file or the ending operation of the browsing unit 1 (step S1). As a method of monitoring the execution of the operation, a method that is standardly used in an application resident in the system is used. For example, in the case of MS-Windows, a Windows message generated when the operation is performed is monitored, and the operation can be monitored by hooking the message. As another method, when an existing application is used in the browsing unit 1, it is possible to detect the set operation as a function of the application itself, and to execute a process according to the operation. . For example, MS-Windows or MS-Excel, which are applications of MS-Windows
l, the macro language VBA (Visual Basi
It is possible to customize the operation of the application by rewriting the application command itself using c for Application).
By modifying the save command, a series of registration processing at the time of saving can be executed. It is also possible to create a macro that is automatically executed during the operation. For example, A
A process for closing an arbitrary file with the auto_Close () macro and a process for terminating the Word itself with the Auto_Exit () macro can be described, respectively. Can be executed.

When a preset save or end operation is detected (step S2), the registration control unit 4 activates the keyword extraction unit 5, and the keyword extraction unit 5 browses, edits, and creates the information using the browsing unit 1. A keyword is extracted from the equalized document (step S3).

Subsequently, the attribute acquisition unit 6 is started, and the browsing unit 1 is started.
The attribute values of the file name, the path name, the file type, the media type, the file creation date and time, the title, and the author are obtained (step S4).

Subsequently, the index information creating section 7 is started, and the index information shown in FIG. 2 is created based on the keywords extracted by the keyword extracting section 5 and the respective attribute values acquired by the attribute acquiring section 6 (step). S5).

Subsequently, the index information creating section 7 registers the created index information in the index database 9 (step S6).

A method for acquiring each attribute value in the attribute acquiring unit 6, a method for creating index information in the index information creating unit 7, and a method for registering index information in the index database 9 in the index information creating unit will be described later. I will explain again.

Subsequently, it is determined whether the browsing unit 1 is continuously operating (step S7). If the browsing unit 1 is continuously operating due to registration at the time of saving or registration with the window closed, the process returns to the monitoring state (step S1) again, and the above operation is continuously performed.

As described above, the creation and registration of the index information is performed in the registration control unit 4.

Next, a method of acquiring each attribute value in the attribute acquiring section 6 will be described.

The file name and the path name are obtained directly from the browsing unit 1. When an existing application is used for the browsing unit 1, attributes are acquired from the OS and the functions of the application. For example, in the case of an application on MS-Windows, attributes can be acquired by OLE automation or the like.

The file type is obtained from the file name. For example, in the case of MS-Windows, the file type can be obtained from the extension part of the file name.

The media type is obtained by extracting the drive name from the path name and checking the drive type from the function of the OS.

The file creation date is obtained by using the function of the OS. For example, in the case of MS-Windows
It is implemented using each function of owsAPI.

The title is such that the document file is, for example, M
If a file has a title as an attribute of the file itself as in the case of an S-Word document file, this title is used as it is. If the document file does not have a title as an attribute, or if the method of acquiring the attribute is not known, for example, the first sentence of the text part of the document file is used as the title. If this one sentence exceeds the size of the character string field, up to that size is used as the title.

If the document file has the information of the author as its own attribute, the author uses the value as it is. If the document file does not have author information as an attribute or if the attribute acquisition method is unknown, the OS on which the document management device operates has an API for extracting the author of the document file. In this case, the author is obtained by this API function. If there is no API or if acquisition of the value fails, an empty character string is used as the value.

When an existing application is applied to the browsing unit 1, if the attribute value as described above can be acquired as a function of the application, the attribute value is acquired by this function. For example, MS-Wi
In the case of a Windows application, many of the attribute values can be obtained from the application by the OLE automation function.

As described above, each attribute value is obtained by the attribute obtaining unit 6.

Next, a method of creating index information in the index information creating section 7 will be described.

First, one new index is generated, and an ID number determined by (ID number) = (ID number of the index created immediately before) +1 is set. As long as a unique value can be set for each index as the ID number, the above method may be used. For example, a method of preferentially assigning the ID numbers that have become missing due to the deletion of unnecessary indexes such that the data at the index destination is lost, starting from the smallest one.

Subsequently, each keyword extracted by the keyword extracting unit 5 is set. If no keywords are extracted, this field will be empty list type. When the number of keywords exceeds the upper limit of the maximum number of elements supported in advance as a list type, list types corresponding to the maximum number of elements are formed in the order in which the keywords are detected.

Finally, the attribute values of the file name, the path name, the file type, the media type, the file creation date and time, the title, and the author acquired by the attribute acquiring unit 6 are set.

As described above, the index information is created in the index information creating section 7.

Next, with reference to FIG. 6, the operation of the index information creating section 7 for registering index information in the index database 9 will be described.

The index information creating section 7 checks whether or not the index information of the same document as the created index information already exists in the index database 9 by using an index having the same path name as the index information. It is checked whether the information is in the index database 9 (step S11).

If there is no index information with the same path name, the created index information is newly registered in the index database 9 (step S12).

If index information of the same path name already exists, the attribute information of the registered index information is compared with the attribute values of the created index information, and if one or more different attribute values exist, (step S13) ), The existing index information is updated with the index information created this time (step S14).

If there is no different attribute value, the index information created this time is discarded because there is no change (step S15), and the process ends without registration.

As described above, the index information is registered in the index database 9 in the index information creating section 7.

Next, referring to FIG. 7, a description will be given of a document search processing operation in the search unit 10. FIG.

A search formula for the index database 9 is input to the search unit 10 via the user interface unit 15 (step S21). The contents of this search expression depend on the index database 9. For example, if the index database 9 is SQL (Structured)
In the case of a Query Language (DB) -based database, a search expression in an SQL statement is used.

Subsequently, the search unit 10 searches the index database 9 for index information using the search formula (step S22), receives the search result, and sends it to the search result presentation unit 14 (step S23). The search result presentation unit 14 presents the searched index information to the user interface unit 15.

If there is no desired document in the search result presented in the search result presentation unit 14, the user can continue to discard the current search result and start the search again from step S21. If the search result is too large to find the desired document, an additional search for the current search result can be performed (step S24). When performing an additional search, the current search result, that is, the ID numbers of all index information of the searched document are stored as data in the memory (step S25), and the index information is stored in the index database 9 by the additional search. Is obtained, only the ID number that matches the ID number in the memory may be extracted. Further, by storing the search results of each search, it is possible to return to the previous search results or to perform a plurality of additional searches in parallel.

As described above, the document search is executed in the search unit 10.

Next, referring to FIG. 8, search result presentation section 1
The operation of obtaining the search result in No. 4 will be described.

First, the user selects a desired document from the index information presented on the user interface unit 15 (step S31). Next, a file name and a path name are extracted from the index information of the selected document (step S32), and the file name and the path name are read by the browsing unit 1.
(Step S33). The browsing unit 1 reads the corresponding document file from the file storage unit 8 based on the file name and the path name and presents the document file (step S34).

As described above, the retrieval result presentation unit 14 acquires the retrieval result.

Next, a method of presenting search results in the search result presenting section 14 will be described. In the search result presentation unit 14,
As shown in FIG. 9, the search result is presented on a display screen of the display device in a tabular presentation window and a tree presentation window. In the tabular presentation window, the contents of the index information of each document are presented in tabular form in order from the highest search score. The tree-form presentation window presents a tree based on the path information included in the searched index information.

The two presentation windows operate in cooperation with each other by the cooperation control unit 13. For example, when an arbitrary document presented in the tabular presentation window is clicked and selected with a mouse or the like, a portion of the document in the tree presentation window is selected and can be seen at a glance by highlighting or the like. Similarly, when an arbitrary document presented in the tree format presentation window is selected, the document in the table format presentation window is selected.

For this purpose, the cooperation control unit 13 has a function of transmitting the ID number of the index information for the document selected in one presentation window to the other presentation window.

Further, in the tree format presentation window, document files not searched in each folder may be presented simultaneously (see FIG. 10). in this case,
The searched files are highlighted so as to be distinguished at a glance from the unsearched files.

As described above, the retrieval result presentation section 14 presents the retrieval result.

(Second Embodiment) A document management apparatus according to a second embodiment of the present invention is configured such that the browsing unit 1 shown in FIG.
In an example in which a browser application is applied, a WWW page (W
This is for automatically creating index information necessary for searching for the WWW page later with respect to the page displayed on the WWW browser) and searching for the desired WWW page using the index information. is there.

In the case of a WWW page, the entity being browsed is usually outside the local machine. Further, the entity is often updated daily, and in many cases, filing index information for the entity does not help at a later date. For this reason, in the second embodiment, the above WW
A function of creating a copy of the W page in a file system on the local machine is added, and index information for the copy is created and registered in an index database.

[0095] In addition, WWW
While browsing pages, you realize that you are browsing a huge number of pages without your knowledge. In the case of the method of registering all of the browsed documents (index information) as in the first embodiment, there is a problem that the number of registrations becomes enormous. Therefore, in the second embodiment, a function of registering profile information in advance and performing a filtering process based on the profile information on a browsed WWW page is added. Note that the browsing unit of the document management device according to the second embodiment, as shown in FIG.
The application is not limited to the W browser 103, and an existing application such as an editor or a word processor may be applied. The former function of generating an index by copying entities outside the local machine is used when browsing or editing document files on various removable media such as floppy disks and magneto-optical disks with applications such as editors and word processors. Can be applied. The latter filtering process using profile information can be applied to a document file as it is.

FIG. 11 shows an example of the configuration of a document management apparatus according to the second embodiment. In FIG. 11, the same portions as those in FIG. 1 are denoted by the same reference numerals, and different portions will be described. That is, in FIG. 11, the browsing unit 1 of FIG. 1 is replaced with a WWW browser 103, and the registration operation setting unit 2 and the registration operation definition table 3 of FIG. 1 are the profile setting unit 101, the profile registration table 102, the filtering unit 106, the WWW Page acquisition and storage unit 117
, And further, the profile information presentation unit 117
Has been added.

The WWW browser 103 is composed of an existing browser application, but may be a dedicated one.

The profile setting section 101 is for setting profile information (see FIG. 12) used for performing the document filtering process performed by the filtering section 106. As shown in FIG. Keywords and multiple URLs (Uniform Reso
source Locator) can be set.

The profile registration table 102 stores the profile information set by the profile setting unit 101 as shown in FIG.
3 is stored in a table format.

The filtering unit 106 compares the keyword extracted by the keyword extracting unit 5 with the attribute value acquired by the attribute acquiring unit 6 and the latest profile information set in the profile registration table 102, and determines whether to perform registration. The registration control section 4 is notified of whether or not it is not. When the keyword and attribute value extracted from the WWW page being browsed match the profile information, the registration control unit 4 sets the
Register the page.

The WWW page acquisition and storage unit 107
The objects constituting the page viewed by the browser 103 are grouped into one folder and copied to the file storage unit 8.

The profile information presenting section 117 is for graphically presenting the contents of the profile registration table 102 in a time-series manner, and can also search and delete WWW pages based on the presented profile information (described later). .

FIG. 14 shows the structure of the index information, which is composed of the following items: ID number, URL, folder name, top file name, title, creation date, keyword, filtering type, and hit keyword. One for each WWW page to be created.

The ID numbers are issued in the order of creation of the index information in the order of “1,” “2,” “3,” and so on, and are unique integer value data in all the index information of the index database 9.

The URL is the URL of the WWW page to be registered.
Is character string data.

The folder name is character string data representing the path name of the folder storing the WWW page copied on the file storage unit 8.

The head file name is character string data representing the file name of the file in which the HTML document of the head page is copied among the files in the folder.

The title is character string data representing the title given to the WWW page to be registered.

The creation date and time is date type data indicating the date and time when the copied file was created or the last update date and time.

The keyword is list-type data whose value is the keyword extracted by the keyword extraction unit 5 for the text portion of the WWW page. If no keywords are extracted, this field will be empty list type. If the number of keywords exceeds the upper limit of the maximum number of elements predetermined as a list type, a list type for the maximum number of elements is formed in the order in which the keywords are detected.

The filtering type indicates whether the filtering process for the WWW page to be registered is performed by the URL defined in the profile, by the keyword, by both, or not by the filtering. Is defined in advance and takes one of the defined values shown in FIG. The hit keyword is list-type data in which, when filtering processing is performed on a WWW page to be registered by using a keyword, among keywords extracted from the WWW page, a keyword that matches a keyword of the profile information is used as a value. . If filtering by keyword is not performed, this field will be an empty list type.

Next, with reference to FIG. 16, a description will be given of a processing operation for creating and registering index information in the registration control unit 4. FIG.

It is monitored whether a new WWW page is displayed on the WWW browser 103 (step S41). As this monitoring method, a method standardly used in an application resident in the system is used. For example,
In the case of MS-Windows, a Windows message generated when a new WWW page is displayed is monitored, and by hooking the message, it is detected that a new WWW page is displayed.

If the display of a new WWW page is detected (step S42), the profile registration table 10
2 to check whether a URL is registered as a profile (step S43).

If the URL is not registered in the profile, the flow advances to step S46. On the other hand, U
If the RL has been registered, the process proceeds to step S44, where the attribute acquiring unit 6 is activated, and the attribute acquiring unit 6
RL is acquired from the WWW browser 103 (step S
44).

Next, the filtering unit 106 is activated,
URL registered as profile and current W
A comparison is made with the URL of the WW page to check whether the same URL exists (step S45). If you have the same URL,
The following processing is executed. If the same URL does not exist, the registration processing is interrupted, and the process returns to step S41 to monitor the WWW browser.

Next, by referring to the profile registration table 102, it is checked whether a keyword is registered as a profile (step S46). If no keyword is registered in the profile, the process proceeds to step S49. On the other hand, if a keyword is registered in the profile, the process proceeds to step 47, where the keyword extracting unit 5 is started,
A keyword is extracted from the text information in the WWW page (step S47). Note that, as described above, the extraction of the keyword is performed by a method usually used in a normal filing system or search system.

Subsequently, the filtering unit 106 is activated, and the keyword extracted from the WWW page is compared with the keyword registered as a profile in the profile registration table 102 to perform collation (step S4).
8). If there is no matching keyword, that is,
If the same keyword as the keyword registered as the profile does not exist in the WWW page, the WWW
The registration of the page is interrupted, the process returns to step S41, and W
Monitors the WW browser.

Then, it is checked whether or not the index database 9 has index information having the same URL as the WWW page (step S49). Same URL
If there is no index information, the process proceeds to step S51, and the subsequent registration processing is executed. When there is index information having the same URL as the WWW page in the index database 9, a copy of the WWW page in the folder pointed to by the index information and each file constituting the WWW page being viewed and Are compared with each other, and if no different file exists (step S5)
0) Since it can be determined that the same page as the browsed WWW page has already been registered, the current registration processing is completed, and the process returns to step S41 to monitor the WWW browser again. On the other hand, if at least one different file exists, the process proceeds to step S51, and the subsequent registration processing is executed.

In the registration process of the WWW page, first, the WW
The W page acquisition / storage unit 107 is activated, and a copy of the WWW page is created in the file storage unit 8 (step S).
51). The creation of the copy is performed by using a method generally performed by an application having an automatic circulating function of a WWW page.

Next, the attribute acquisition unit 6 is activated to acquire the attribute values of the folder name, the head file name, the title, and the creation time from the WWW page being viewed and a copy of the WWW page (step S52). ). The title is obtained directly from the WWW browser 103. Keep the folder name and first file name information when making the copy,
It is obtained by reading this. As the creation time, the creation time of the copy destination folder is obtained in the same manner as in the first embodiment. Alternatively, the current time may be obtained by the clock function of the OS, and this may be used as the creation time. The URL used is the one previously obtained in the process (step S44).

Subsequently, the index information creating unit 7 is started, and index information is created based on the keywords extracted by the keyword extracting unit 5 and the attribute values acquired by the attribute acquiring unit 6 (step S53). The method of creating the index information is the same as in the first embodiment. The created index information is newly registered in the index database 9 (step S54). After that, the process returns to step S41, where the WWW browser 103 is monitored, and the above processing is continuously performed until the browser terminates.

Next, the operation of searching for a registered WWW page will be described. The document management apparatus in FIG. 11 has two search functions, a search function similar to that of the first embodiment performed by a search formula input to the search unit 10 and a search function from the profile information presentation unit 117. .

First, a search processing operation performed by the search formula input to the search unit 10 will be described. Here, the operation of the search result presentation unit 14 is different from that of the first embodiment. The search result presenting unit 14 presents the retrieved WWW pages in a table presenting window and a tree presenting window as shown in FIG. In the tabular presentation window, the contents of the index information of each WWW page are presented in tabular form from the top of the search score. In the tree type presentation window, those having the same URL among the WWW pages are put together in one hierarchy, and as shown in FIG. 17, presentation is performed in a tree structure of two layers as a whole. These two presentation windows are operated by the cooperation control unit 13 in cooperation with each other as in the first embodiment.

In the tree format presentation window, U
It is also possible to perform a tree display as shown in FIG. 18 in which the domain display portions of the RL are hierarchically arranged in order from the right side element, that is, the first domain.

Next, a search processing operation from the profile information presentation section 117 will be described with reference to FIGS. 19 and 20.

FIG. 19 shows an example of a display screen displayed on the display device by the profile information presenting section 11. The profile information presenting unit 11 is a graphic display of the contents of the profile registration table 102 in accordance with the time axis 201.
The URL display area 204 and the keyword display area 2 are indicated by a line segment representing the RL and the keyword, each of which represents a period (a used period set as profile information).
05 is displayed in each area. For example, the URL "www.a
aa. ddd. edu ”has been available since mid-November 1999
Until the end of January 2000, the keyword "network" was 2
It can be confirmed from the display of FIG. 19 that the profile information is valid until the end of January 2000. The display areas 204 and 205 can be scrolled left and right (on the time axis) by clicking scroll buttons 202 and 203 provided on the left and right of the time axis 201 with a pointing device such as a mouse.

Hereinafter, the search processing operation from profile information presentation section 117 will be described with reference to the flowchart shown in FIG.

First, the user selects an arbitrary URL and a keyword from the display screen shown in FIG. 19 displayed by the profile information presentation section 117 (step S61).
Hereinafter, a case where both a URL and a keyword are selected will be described as an example, but the same applies to a case where only one of them is selected. As a selection method, a line segment representing a URL and a keyword are respectively selected by clicking with a pointing device, and a line segment 206 designating a time indicated by a vertical dotted line is horizontally moved by the pointing device as shown in FIG. There are two types of selection methods, that is, a method of selecting by moving and overlaying on a line segment of a desired URL or keyword. In the latter case, it is also possible to use two line segments 206 and select a URL and a keyword in a rectangular area surrounded by both line segments.

Next, the search button 207 is pressed (step S62). Subsequently, when the selected URL and keyword are transmitted to the search unit 10 (step S63), the UR
By the filtering process performed with L and the keyword, the index information of the WWW page that has already been registered is searched by the field search for each field of the filtering type, the URL, and the hit keyword (step S64).

Subsequently, the search result is transmitted to the search result presentation unit 14, and the search result is presented in the same manner as the search result in the search formula as shown in FIGS. 17 and 18 (step S6).
5).

Thereafter, similarly to the search of the first embodiment, a WWW page is selected from the search results (step S66).
The file name and the path name are obtained from the corresponding index information (step S67). Subsequently, the file name and the path name are notified to the WWW browser 103 (step S68),
The WWW browser 103 reads the corresponding WWW page from the file storage unit 8 and presents it (step S6).
9).

Next, the process of deleting the index information, the copy file of the WWW page, and the profile information in the profile information presentation section 117 will be described.

The profile information presenting section 117 has the function of searching for the WWW page from the profile information described above, and also stores the searched index information and the copy file of the WWW page from the index database 9 and the file storage section 8, respectively. Further, it has a function of deleting profile information from the profile registration table 102, respectively. With this function, it is possible to effectively delete the profile information set in the past that has become unnecessary and the copy file and index information of the WWW page corresponding to the profile information. Hereinafter, the deletion process will be described with reference to the flowchart shown in FIG.

First, the user selects an arbitrary URL and a keyword displayed on the profile information presentation section 117 (step S71). Hereinafter, a case where both a URL and a keyword are selected will be described as an example, but the same applies to a case where only one of them is selected. As a selection method, a method of clicking and selecting a line segment representing a URL and a keyword with a pointing device, and moving a line segment 206 specifying a time indicated by a vertical dotted line as shown in FIG. , A desired URL, and a method of selecting by superimposing on a line segment representing a keyword. In the latter case, the line segment 2 that was valid before the designated time, that is,
A URL that exists only in the area on the left side of 06, a line segment representing a keyword can be selected, or two line segments 206 specifying time can be selected, and the URL, You can also select keywords.

Next, the delete button 208 is pressed (step S72). At this time, it is checked whether the same URL and keyword as the selected one exist other than the selected one (step S73). If there are, these URLs and keywords are excluded from the selection (step S74). Then, it is checked whether the selected URL and keyword remain (step S75). If there is, the process proceeds to step S76, and if not, the process ends without deleting.

Subsequently, the URL and the keyword are entered in the search unit 10.
(Step S76), and the registered WW is registered by the filtering process performed with the URL and the keyword.
W page index information is filtering type,
The URL is searched by field search for each field of the hit keyword (step S7).
7).

Next, the profile information presenting section 117 determines, for each of the searched index information items, a URL other than the index information selected, a keyword other than the selected index information from the filtering type, the URL, and the respective field values of the hit keyword. (Step S78). Other URLs,
If it is filtered by a keyword, the index information is excluded from the deletion target (step S79).
As a result of the above processing, when there is index information to be deleted (step S80), step S81.
The process proceeds to step S84 if there is no remaining.

The profile information presentation section 117 acquires a file name and a path name from the index information to be deleted (step S81). Profile information presentation unit 117
Then, the copy file of the corresponding WWW page is deleted from the file storage unit 8 (step S82), the corresponding index information is deleted from the index database 9 (step S83), and finally the file is deleted from the profile registration table 102. The URL and the keyword, which are the profile information of the file of the WWW page, are deleted (step S84).

It is to be noted that the above embodiment is not limited, and the present invention can be appropriately modified and implemented by, for example, combining the first embodiment and the second embodiment without departing from the scope of the invention.

As described above, according to the above-described embodiment, by detecting the operation of the browsing unit 1 and automatically creating the index information at the time of the preset operation, the user can actually create the index information. It is possible to automatically create index information for a document that has been edited or viewed, and easily retrieve and call the document later using this index information.

In addition, by filtering a document (for example, a WWW page) browsed based on a preset profile and copying the browsed document file, for example, among a huge number of documents obtained through a WWW browser, Only those that match the profile information are automatically copied to the file storage unit 8 when browsing,
Further, index information for the copied data is automatically created, and a document can be easily searched and retrieved later using the index information.
