Here, the database 310 is a generic term for the user database 104, the bookmark database 105, and the image database 106.

 [0031] <User data structure>

 FIG. 4A is a diagram for explaining an example of the structure of user data stored in the user database 104. User data is composed of various information related to the characteristics and attributes of individual users.

In FIG. 4A, 401 is a user ID, which is an identifier given to the unique to uniquely identify each user. A password 402 is used for authentication when each user accesses his / her registration information or uses a bookmark. 403 is the user's name, 404 is the user's email address, 405 is the age, 406 is the gender, and 407 is the user's active 408 is occupation type, 409 is unmarried, 410 is residence type, 411 is annual income, 412 is private car ownership, and 413 is hobby. Each data is provided in advance by the user and registered as user data. Further, the above contents are given as an example of user data, and it is not necessary that all of them are registered, and other information that characterizes the user may be registered.

 [0033] <Bookmark structure>

 In this embodiment, the bookmark is created and updated by the user. All bookmark data is stored in the bookmark database 105 connected to the server 103 for each user, and when the user starts a web browser on the client 101. Then, it is downloaded to the client 101 and displayed on the web browser.

 [0034] Bookmarks are stored in a well-known directory structure and URL (Universal Resource

 Locator) and a folder that stores the URL as a specific unit. That is, each URL is registered in a directory tree for each user (hereinafter referred to as a bookmark directory) and may be directly under the bookmark directory or in a folder created arbitrarily.

 [0035] FIG. 4B is a diagram illustrating an example of management of information related to a URL registered in a bookmark. In FIG. 4B, ID 421 of the user who uses the bookmark is registered. Thereby, the correspondence between the user and the bookmark can be taken. 422 is each URL to be registered. In Fig. 4B, the power describing the case of registering the URL itself. Furthermore, a URL database may be prepared to manage all URLs in a unified manner. In that case, a unique identification number (ID) will be attached to each URL. Therefore, register the URL identification number in the URL 422 field shown in Fig. 4B.

[0036] Reference numeral 423 denotes a bookmark name given to each URL. The bookmark name 423 may be a name arbitrarily set when the user registers the bookmark, or may be a name originally assigned to the page. 424 indicates the date and time when the page corresponding to the URL was created, 425 indicates the date and time when the URL was most recently updated, 426 indicates the date and time when the user last referenced the page, In 427, the number of times the user refers to the page is registered. 428 is a reduced image of the page (thumbnail (Storage location in the image database 105) is registered. This storage location 428 may be omitted when an identification number is registered in the URL 422 according to the configuration of the image database 106 described later.

 Here, the server 103 periodically monitors the update of each page registered as a bookmark, and updates the contents of the update date and time 423 when there is an update. Further, a reduced image of the updated page is generated, and the contents of the corresponding reduced image stored in the image database 105 are updated.

 [0038] <Image database configuration>

 The image database 106 registers the reduced image of the page corresponding to the URL registered in the bookmark database 105! /.

 For example, the image database 106 is configured as shown in FIG. 4C. Here, `` Z: ¥ '' is the root directory, and folders `` image0001 '', `` image0002 '' and `` image0041 '' are registered directly under the root directory, and JPEG image data `` 001. “jpg”, “031.jpg”, and “005.jpg” are stored. As described above, in the directory structure, the reduced image data of the page is stored in the image database 106. Therefore, in the bookmark database 105, it is possible to correspond to the registered URL simply by registering the link information. A reduced image to be identified can be uniquely specified.

 [0040] If the identification number is registered in the URL 422, the image database 106 uses the identification number of the corresponding URL as the file name of the image data as it is, and stores it in the folder in units of an appropriate number of files. It can be realized just by storing it. For example, if an image is stored in one folder for every 1000 files, URL identification numbers “10000 .jpg” and “19999.jpg” can be stored in a folder with a folder name “10000”. wear. In this case, the bookmark database 105 does not need to have the image storage location 428 in FIG. 4B, and the corresponding reduced image is searched by searching for an image having a file name that matches the identification number registered in the URL 422. Can be identified.

[0041] The image data registered in the image database 106 may be displayed in the bookmark when the web browser is started in the user client 101. However, in the embodiment of the present invention, the image data is mainly stored in the web browser. A page similar to the page that appears and speaks. This is used when presenting the page to the user.

 [0042] <Display screen example>

 An example of the display form of the web browser in the client in this embodiment is as shown in FIG.

 In FIG. 5, reference numeral 500 denotes the entire browser screen. Normally, web browsers have menu bars and buttons. In Figure 5, these are omitted, and a display example of only the part where web pages are displayed is shown. The screen 500 includes a first area 501 for displaying a page mainly viewed by the user (hereinafter referred to as “main page”) and a page similar to the main page (hereinafter referred to as “similar page”). It is divided into a second area 502 for displaying a reduced image. The screen information displayed in the second area 502 is hereinafter referred to as similar page screen information. The form in which the area in the screen 500 is divided is not limited to the form shown in FIG. 5, and the second area may be provided in any one of the upper, lower, and right areas in the screen 500, for example.

 In FIG. 5, a page of “Yuhi Bank” is displayed in the first area 501. In the second area 502, a similar page 504 is displayed, and a scroll button 503 for scrolling the screen is displayed. By operating the scroll button 503, the reduced image of the page displayed in the second area 502 can be arbitrarily scrolled.

[0045] Each reduced image can accept a selection based on a user's mouse operation. For example, when a page 504 described as "ABC bank" is click-selected, the page 504 is displayed as the first page. Displayed in area 1 501 of 1.

[0046] As described above, according to the present invention, information on a page similar to the page displayed in the first area 501 is visually provided, and a page that the user may be interested in is provided at any time. I can go.

[0047] <Process for providing similar page screen information>

Next, a process for providing the page information similar to the main page (similar page screen information) displayed in the first area 501 from the server 103 to the client 101 will be specifically described. FIG. 6 is a flowchart corresponding to an example of the generation / provision processing of similar page screen information executed in the server 103.

In step S601, information on the main page displayed in the first area is acquired.

 The information to be acquired here is information that can be specified by the main page. If it is already registered in the user's bookmark, it can be the bookmark name 423! /, UR

L may be sufficient.

 [0050] Note that the server 103 and the client 101 regularly communicate with each other in order to obtain the information on the main page, and the contents of the main page displayed in the first area 501 are displayed on the client side. When changed, the client 101 notifies the server 103 of information about the new main page. In addition, the client 101 may receive the main page designation from the user, and transmit the main page information to the server 103 in response to accepting the instruction. In this case, a search button for similar pages is arranged in the browser, and a request for provision of screen information of a similar page of the page currently displayed as the main page is accepted by operating the search button. Can do.

 [0051] Next, in step S602, the server 103 searches the bookmarks of the user registered in the bookmark database 105 for bookmarks in which the main page information specified in step S601 is registered.

 For example, considering a case where a page of “Yuhi Bank” is displayed as the main page, a bookmark that registers this page is searched. Figures 7A and 7B are diagrams showing an example of bookmark registration for user A (Figure 7A) and user B (Figure 7B), which are different from the user who requested the provision of similar page screen information. Is

In FIG. 7A, it can be seen that the URL “www.yuuhi.com” of the page of “Yuhi Bank” is registered in the bookmark. On the other hand, in FIG. 7B, the page of “Yuhi Bank” is not registered, including the folder named “Bank”. Therefore, in such a case, only the bookmark of user A corresponds to the target bookmark, and the bookmark of user B does not correspond to the target bookmark.

[0054] Next, in step S603, all bookmarks found in step S602 are displayed. Therefore, the main page is registered, and information on other pages in the folder is acquired for each user.

 For example, in the bookmark shown in FIG. 7A, the URL of “Yuhi Bank” is registered in a folder named “Bank”. Therefore, in step S603, for user A, information on other pages registered in the folder name “bank” is acquired. Here, if the URL of the main page is registered directly under the root, the page registered directly under the root can be obtained in the same way.

 [0056] In step S604, ranking is performed on the basis of the number of folders stored and stored for each of the information on the other pages extracted in step S603.

 [0057] For example, ABC bank having the URL "www.abcbank.co.jp" is registered in the bookmark of user A in FIG. 7A. If this ABC bank was registered in the same folder as “Yuhi Bank” in the bookmarks of other users C and D not shown in FIGS. 7A and 7B, at least ABC bank was stored. The number of folders is 3. In this way, the total number of registered pages stored in the same folder as “Yuhi Bank” is calculated for each page.

 In step S605, based on the result obtained in step S604, a similar point Psl representing the degree of similarity with the main page for other page information is calculated. Here, the similarity point Psl indicates that the higher the number of points, the higher the similarity with the main page.

 [0059] A specific example of the similar point Psl will be described with reference to FIG. FIG. 8 is a table showing an example of the number of registered folders and similar points Psl calculated for other pages registered in the same folder as the main page. In FIG. 8, 801 is the URL of the other page, 802 is the number of folders in which the corresponding URL is registered, and 803 is the similar point Psl calculated based on the number of folders.

[0060] In FIG. 8, the power of simply matching the similar point Psl with the number of registered folders may be weighted in descending order of the number of registered folders (that is, when the number of registered folders is 1st, Calculate the similar point Psl by multiplying the number by 1.5 and multiply it by 1.4 if it is in the second place.) ₀ Such weighting is for example similar pages to multiple similar points This is effective when trying to determine the total. First, similar Point Psl is determined.

 [0061] Next, in step S606, the folder names in which the main page is registered are extracted for all the bookmarks. That is, in the case of FIG. 7A, since the folder name where “Yuhi Bank” is registered is “bank”, the folder name “bank” is extracted for user A.

 In step S607, the number of extracted folder names, that is, the number of folders in which each folder name is used is calculated as a point Pf. For example, if “Yuhi Bank” is registered in the folder named “Bank” and there are 50 users !, the point Pf can be set to “50”.

 [0063] In step S608, an Internet search is performed using the folder name as a keyword for a folder name whose point Pf is greater than the predetermined threshold TM. This search can be performed using a general purpose search engine. The search is preferably performed using a plurality of different search engines. The threshold TM is determined according to the number of users registered in the user database 104, in other words, the number of bookmarks registered. Also, without setting a threshold, you can use as a keyword the folder name of the top number (for example, 10, 50, 100, etc.) in descending order of point Pf! /.

 [0064] In step S609, information on other pages (that is, other than the main page) is extracted from the pages listed in the search results set with the folder name as a keyword, and the order in which the pages are listed. Weighting is used to calculate the similarity point Ps2.

FIG. 9 is a table for explaining a specific example for calculating a similar point Ps2 by performing a search with a predetermined keyword using a predetermined search engine among a plurality of available search engines. In FIG. 9, 901 is a folder name used as a keyword for search. Here, two cases of “bank” and “finance” are listed as examples. 90 2 is a URL listed in the search result when a search is performed for each keyword 901. Reference numeral 903 indicates the order in which the corresponding URL is listed in the search result! For example, ABC Bank, which is given the URL “www.abcbank.co.jp”, is listed first in the search results when the keyword is “Bank” for a given search engine. The power that ranks 903 becomes “1” When “finance” is a keyword, it is listed third, so list rank 903 is “3”. Next, 904 represents the weight for each keyword. As the weight 904, the point Pf calculated in step S607 may be used as it is, or a result obtained by processing the point Pf by further weighting may be used. In any case, a value that reflects the value of point Pf is used. In the case of FIG. 9, “100” is given as the keyword weight 904, assuming that the name “bank” is the most frequently used as the folder name. Also, although the name of “financial” is not as large as that of a bank, it was used as a folder name as it is, so “60” is given as keyword weight 904! /.

 [0067] Next, reference numeral 905 denotes a rank weight, and a weight given according to the order listed in each search result is registered. In the case of Fig. 9, the weights from 10 to 2 are given from 1st to 9th, and the weight is 1 after 10th. Therefore, ABC Bank was ranked first in the keyword “Bank”, so “10” was given as the ranking weight 905, and “3” was given in the keyword “Finance”, so “8” was given as the ranking weight 905. ! /

 [0068] Next, reference numeral 906 denotes the calculation result of the similar point Ps2 '. The similarity point Ps2 ′ can be obtained simply by keyword weight 904 X rank weight 905. Therefore, in the case of ABC Bank, the keyword “bank” is Ps2, = 1000, and the keyword “finance” is Ps2, = 480.

 Note that FIG. 9 illustrates the case of a predetermined search engine. Even when a search engine other than this is used, each search engine is based on the information shown in FIG. Therefore, the similar point Ps2 is calculated.

 [0070] Then, the similar point Ps2 obtained in step S609 is given as the sum of the similar points Ps2 'calculated for each URL.

 [0071] In step S610, the similar points Psl and Ps2 calculated in step S605 and step S609 are converted to calculate the final similar point PS, and the similarity to the main page is high. Determine the page.

 [0072] In step S611, similar page screen information is generated using the reduction information of each page in the order of pages determined to have a high similarity in step S610, and is transmitted to the client.

In this embodiment, similar page information is used as similar page screen information. The information is provided to the client 101 as information including a reduced image of the page, but the form for providing similar page information is not necessarily based on the image, only the page name, URL, or page. You may carry out by the text etc. which describe the outline | summary of the content. You may do this.

 As described above, according to the present invention corresponding to the present embodiment, information on a page similar to the page displayed on the web browser is displayed on the same screen. You can easily find the pages you are interested in, which can dramatically improve the efficiency of information collection.

 [0075] Also, users who want to see other pages that are similar to the page they are currently viewing, but who are not good at selecting keywords appropriately, are similar to the pages they are currently viewing. This provides an easy-to-use web surfing service that can dramatically improve user convenience.

 [0076] Furthermore, the present invention can determine similar pages using the characteristics of bookmarks. This brings about a special utility as described below.

 [0077] Normally, if a basic page is registered in a bookmark, its variational page is not often registered. For example, a user who registers a page for a parent company is more likely to register pages for other companies in the same industry than to register pages for their subsidiaries and affiliates. In other words, when a user tries to register multiple different pages in the same folder in a bookmark, the content of the page itself is more important than the social relationship such as parent company and subsidiary or parent company and affiliated company. This means that there is a higher possibility of commonality and similarity. Therefore, when the similar page is determined using the registered contents in the bookmark as in the present invention, the commonality or similarity of the content itself is more emphasized between the main page and the similar page. Therefore, it is possible to provide similar page search technology that reflects the judgment on the similarity of page contents.

[0078] In the first embodiment described above, the force described in the case where the similar page is determined using the similar points Psl and Ps2, naturally, only one of Psl and Ps2 is used. You may decide similar pages. [0079] [Second Embodiment]

 In the first embodiment described above, similar points Psl and Ps2 calculated by two calculation methods are used to determine a similar page. In this embodiment, in addition to the similar points described above, Based on the calculation method described below, the similar point Ps3 is further calculated, and the similar page can be determined by the sum of Psl−Ps3.

 FIG. 10 is a flowchart of the similarity point calculation process corresponding to the present embodiment.

 In FIG. 10, step S1001 is equivalent to the processing in step S601 of FIG. 6, and acquires information on the main page displayed in the first area of FIG. In the subsequent step S 1002, a word with a high probability of hitting the main page (hereinafter referred to as a “high probability word”) when the Internet search is executed using the word as a keyword among the words described in the accepted main page. "). Such high-probability words are extracted by performing morphological analysis on the description in the page, and by assigning points to each word based on the content rate, font size, layout position, etc. Probability is high and can be determined as a word.

 For example, as shown in FIG. 11, if the main page 1101 is “Yuhi Bank” of “www.yuuhi.com”, the word 1103 such as “Bank”, “Finance”, “BANK” is a high point 1104 These words 1103 correspond to high-probability words and are used for keyword searches. Here, the point 1104 of each word 1103 can be used for weighting each page hit in the subsequent keyword search.

 In step S 1003, an Internet search is performed using the high probability word determined in step S 1003 as a keyword.

 Further, in step S 1004, according to the result of the Internet search in step S 1003, the listed pages are ranked by weighting corresponding to each keyword, and the similar point Ps 3 is calculated.

[0085] For example, when “bank” is used as a keyword, a search result similar to that shown in FIG. 9 should be obtained. However, in the case of calculating the similar point Ps3, in the present embodiment, FIG. The difference is that the keyword weight in 904 is “90” corresponding to point 1104 in FIG. In this step as well as step S609, search using keywords is performed. For each of the search engines that have been performed, for each page listed in the search results, the similarity point Ps3 is calculated by multiplying the keyword weight determined in step S902 by the rank weight in the search results.

 As described above, the similar point Ps3 can be obtained. Since Ps3 obtained here can be used to determine the similarity between the main page and other pages in the same way as Psl and Ps2 in the first embodiment, the similarity is calculated up to Psl force Ps3. Judgment can be made based on the total. Information on similar pages obtained as a result can be provided to the user in the same manner as in the first embodiment.

 [0087] As described above, according to the present invention corresponding to the present embodiment, a page including information common to the page displayed mainly on the web browser is extracted as a similar page and provided to the user. As a result, the user can easily find the page that he / she is interested in, and the efficiency of information collection can be greatly improved.

 [0088] [Third embodiment]

 In the first and second embodiments described above, a case has been described in which information on a page determined to be similar to the main page is provided to the user without any filtering. For example, in a page provided as a similar page There is a possibility that there is also a page that the user has already registered as a bookmark. In such a case, the user cannot receive any new information, so the efficiency of information collection cannot be improved.

 Therefore, in the present embodiment, an invention that can preferentially provide a page other than a page registered in advance as a bookmark as a similar page will be described.

 [0090] Since the bookmark information of the user referring to the main page is registered in the bookmark database 105, the server 103 displays the page information included in the bookmark information in FIG. 6 and FIG. Exclude from processing target and execute each processing.

[0091] For example, after the similarity is finally determined by the sum of Psl and Ps2, or the sum of Psl, Ps2 and Ps3, pages already registered in the bookmark are excluded from the page information provided to the user. That's fine. Alternatively, in the Internet search in step S609 in FIG. 6 and step S1004 in FIG. 10, out of the pages listed as search results, the pages registered in the bookmark are excluded, and similar points Ps2 and Ps3 are calculated. You may do it. It is also possible to sort the display order so that the display order when providing to the user is reversed, without excluding the pages registered in the bookmark.

 [0092] When the history of the page that the user has recently referred to is stored as the reference history in the bookmark, the page remaining in the history is excluded from the processing target and a similar page is determined and the user is notified. It can also be provided. In this case as well, it is sufficient to sort the display order so that the display order when providing to the user is reversed, without excluding the pages remaining in the history.

 [0093] As described above, according to the present embodiment, an unknown page is preferentially provided to a user with respect to a similar page of a page registered by a user or a page that has already been referred to. It becomes possible.

 [0094] [Fourth Embodiment]

 In the third embodiment, when filtering is performed using registration information such as a bookmark, filtering based on the force user data described above is also possible.

 Specifically, the user database 105 stores age 405, sex 40, area attribute 407, occupation 408, hobby 413, etc. for all users. Assuming that the user referring to the main page is a male in his twenties, for example, and his / her hobby is making a personal computer. If this is done, pages that are registered in bookmarks by users with similar preferences are very likely to be useful to users browsing the main page, so effective results can be obtained. High nature.

 [0096] Also, if the residential area is different, the information required for each area may be different. For example, even if a user has a hobby of eating and drinking, the contents registered in bookmarks are naturally different for users living in the Kyushu region and users living in Hokkaido, and one information is not always useful for the other. Absent. In such a case, by using the regional attribute 407, the search range can be limited for each region, and information on similar pages that are more effective for the user can be provided.

Therefore, in the present embodiment, the user's information registered in the user database 105 is used to restrict the bookmarks used when calculating the similar points, thereby limiting the user. An invention that is more preferable to users and that can provide similar pages will be described.

 [0098] First, since the user data of the user who is referring to the main page is registered in the user database 104, the server 103 receives information (for example, age 405, gender 406, Predetermined information is selected from the regional attributes (407, hobbies 413, etc.), and users having information common to the selected information are narrowed down in the user database 104. In this way, after narrowing down the users in advance, the processing in step S602 and step S606 in FIG. 6 is executed.

 [0099] As a result, the bookmark information used to calculate the similarity points is limited to those of users who have a specific relationship with the user who is referring to the main page. Search for similar pages used.

 [0100] As described above, according to the present embodiment, it is possible to search for a similar page using a predetermined relationship between users, and thus it is possible to provide more useful page information for the user. It becomes possible to provide.

 [0101] [Other Embodiments]

 The above processing (for example, processing according to the flowcharts shown in FIGS. 6 and 10 above) is stored as a program in a storage medium such as a CD-R, ROM, DVD-ROM, or MO, and is stored in this storage medium. By loading (installing or copying) this program into the computer, this computer can perform the above processing. Therefore, it is clear that this storage medium is also within the scope of the present invention.
