Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information relay conversion for relaying the transmission and reception of documents having a reference relationship with each other in document information distributed to a plurality of computers connected to a communication network. Method and apparatus.

[0002]

2. Description of the Related Art Conventionally, as an example of a method of describing a reference relation between different documents, HTML (Hyper Text Markup Laptop) is used.
nguage). In HTML, when it is desired to associate a certain part in the document text with another document B, the storage location of the document B and the access protocol are uniquely specified and described as a tag. For example, if there is a description "Nippon Telegraph and Telephone Corporation" in document A and you want to associate it with document B,

<A HREF=“document B on network”>
> Described as Nippon Telegraph and Telephone Corporation </A>. At this time, it is called that a hyperlink is defined in the document B from the corresponding description part “Nippon Telegraph and Telephone Corporation” in the document A. Here, the “document B on the network” refers to a storage location (distributed computer address or document name, etc.) on a distributed computer connected to the network and a protocol for accessing the document. A notation that uniquely indicates
It is called RL (Uniform Resource Locator). Also, <A
HREF = ...> and </A> are examples of tags.

[0003] In this way, it is possible to associate a plurality of documents. However, the authors of individual documents
(1) UR of document to be related by hyperlink
L, knowing the URL correctly, and (3) promptly updating the corresponding tag when the URL of the linked document is changed.

[0004]

However, in practice, the user does not know the URL, has a mistake,
In many cases, a hyperlink to a related document cannot be correctly defined even though there is a related document, for example, because an RL is described. Accessing the related document B from the document A by an incorrect hyperlink not only creates unnecessary traffic on the network and puts an extra load on the server that provides the information, but also increases the number of users who access the document A. Has the problem of providing incorrect information.

[0005] Further, if there are a plurality of locations (in this example, "Nippon Telegraph and Telephone Corporation") that correspond to each other and it is desired to associate all of them with the document B, the tags must be correctly described in all the locations It is necessary to do. But,
Because it is actually cumbersome, it is often the case that hyperlinks are not defined from all applicable words, for example, only from the first occurrence of the word in the document. In this case, there is a problem that not only the entire document becomes inconsistent, but also a reader who sees only the part where the hyperlink is not defined cannot access the related document.

[0006] The present invention has been made in view of the above,
The purpose is to set hyperlinks, UR
It is an object of the present invention to provide an information relay conversion method and apparatus capable of accurately changing a L and defining a hyperlink to the same URL for a plurality of identical descriptions.

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

FIG. 1 is a diagram for explaining an information access method on a plurality of computers distributed in a communication network to which the information relay conversion method of the present invention is applied. In FIG. 1, a computer C1 and a computer C2 are connected to a communication network 1, and the computer C1 attempts to access information D2 managed by the computer C2.

To this end, the computer C1 receives the address A2 of the computer C2 on the communication network 1.
, The protocol of the document access service provided by the computer C2 (or the port number providing the service) P2, and the name of the document to be accessed [D
2], and transmits to the communication network 1. The communication network 1 specifies the computer C2 based on the address A2, and transmits a protocol (port number) P2 and a document name [D2] to the computer C2. The computer C2 determines whether the request is legitimate, and if the request is legitimate, sends the result to the computer C1.
Return to.

The information relay conversion method of the present invention is intended to supplement the document D2 to be transmitted during the exchange between the computers in the communication network described above, and the details thereof will be described below.

FIG. 2 is a diagram showing a configuration of an information relay conversion device for implementing the information relay conversion method according to one embodiment of the present invention. The information relay conversion device 2 shown in FIG. 2 is provided between the computers C1 and C2 shown in FIG. 1, and cooperates with the computer C2 on the information transmission side to supplement the information between the two computers in order to supplement the information. It relays transmission and reception, and includes a request relay unit 201 and a document file receiving unit 2
02, document determination unit 203, replacement processing unit 204, conversion table 2
05, a document file transmission unit 206.

As described above, the computer C2
A is the address that is open to the public for document access
2, the port number is P2, and the document name is [D2]. Then, when accessing this service from the outside, access is made based on the information (A2, P2, D2).

The process shown in FIG. 2 is started on the computer C2, and the communication with this process is set to be performed on the port P2. Here, a process is a unit for performing processing on a computer. With such a setting, an external access by (A2, P2, D2) is a communication with this process. At the same time, the port number for actually providing the service on the computer C2 is changed to P3.

As described above, the computer C1 specifies the address A2 of the computer C2, the port number P2, and the name of the document to be accessed [D2], and transmits it to the information relay conversion device 2 via the communication network. Upon receiving these pieces of information, the request relay unit 201 of the information relay conversion device 2 converts the port number P2 to P3, and (A2, P2
(3, D2) to access the computer C2.

The computer C2 reads the corresponding document D2, and reads the document D2.
02. Thus, the document file receiving unit 202
FIG. 4 shows an example of the document received at the step S1. Document D shown in FIG.
2 is a text file, "NTT DIRECT
ORY ”to“ http: /// navi. nt
t. jp ", a hyperlink is defined, and there is no definition of a hyperlink from another part.

Upon receiving the document D2, the document file receiving unit 202 sends the document D2 to the document determining unit 203,
The document determination unit 203 determines whether the document D2 is a text file. If the document determination unit 203 determines that the file is a text file, it is sent to the replacement processing unit 204. In the case of a document other than a text, the document is sent directly to the document file transmission unit 206 and transmitted to the computer C1 without any change.

The replacement processing unit 204 searches for a character string to be replaced according to the conversion table 205 and replaces the corresponding part. FIG. 3 shows an example of the conversion table 205. The conversion table 205 includes a search character string that is a character string to be searched from a document, and a URL corresponding to the search character string. In the conversion table of FIG. 3, for example, if a document contains the characters “Nippon Telegraph and Telephone Corporation (registered trademark)” or “NTT (registered trademark)”, this character and “ht
tp: // www. ntt. jp]. That is, the character string “Nippon Telegraph and Telephone” in the document is changed to “<A HREF =” http: // www.
ntt. jp "> Nippon Telegraph and Telephone Corporation </A>".

The text file in which the character string has been converted in this way is sent to the document file transmitting unit 206, and the document file transmitting unit 206 sends the computer C1 the document D '.
Sent to.

Next, the operation of the replacement processing unit 204 will be described with reference to the flowchart shown in FIG.

First, the character string is looked at in order from the front, and divided into a portion surrounded by tags and the rest. Hereinafter, a portion that is not surrounded by tags is referred to as a non-decorated character string. By this processing, the text file D2 becomes

## EQU2 ## "Nippon Telegraph and Telephone Corporation provides a service for searching for information on the Internet.""<A HREF =" http: //navi.nt
t. jp "> NTT DIRECTORY </A>" is provided, which is decomposed into a total of three, that is, two non-decorated character strings of "provided." and a character string surrounded by one tag (step S51).

Next, one search character string is extracted from the conversion table (step S52). In the present embodiment, “Nippon Telegraph and Telephone Corporation” is extracted. Then, each non-decorated character string is sequentially looked at from the front, and if there is a character string identical to the retrieved search character string, it is replaced (step S53). In the present embodiment, it is checked whether there is a character string “Nippon Telegraph and Telephone Corporation”, and the corresponding description part is described as “<A HREF =“ http://www.ntt.
jp "> Nippon Telegraph and Telephone Corporation </A>". This is performed for all non-decorated character strings (step S54).

## EQU3 ## "As a service for retrieving information on the Internet, <A HREF =" http: //www.ntt.j
p ”> Nippon Telegraph and Telephone Corporation </A> can be replaced with“ ”.

If this is further decomposed into a portion surrounded by tags and a non-decorative character string,

## EQU4 ## "As a service for searching for information on the Internet,""<A HREF =" http://www.ntt.
jp "> Nippon Telegraph and Telephone Corporation </A>"

The same processing is performed for each non-decorative character string for the next search character string "NTT". By performing these processes on all the search character strings in the conversion table (step S55), the text file D2 shown in FIG.
Is, as shown in FIG.

## EQU5 ## "<A HREF =""http: // www.
isoc. org "> Internet </A>" As a service for searching the above information ""<A HREF = "http: // www. ntt.
jp "> Nippon Telegraph and Telephone Corporation </A>" Then, "<A HREF =" http: // navi. nt
t. jp "> NTT DIRECTORY </A>" is provided. "

The processing result is sent to the document file transmitting unit 206
, The document D2 'with the hyperlink not defined in the text file D2 can be received.

Further, the replacement processing unit 204 performs the replacement processing only on the portion not surrounded by the tag. Therefore, if the document creator explicitly defines the hyperlink, no change is made. For example, in the text file D2, the document creator

## EQU6 ## "A service for retrieving information on the Internet <A HREF="http://www.nttinfo.ntt.jp/"> Nippon Telegraph and Telephone Corporation </A> describes ... In this case, “NTTP: // www. ntt. jp ”is not redefined.

As described above, hyperlinks can be uniformly defined for all documents managed by the computer C2 without bothering individual document creators. At this time, if the document creator defines a different URL for the same phrase, that URL takes precedence, so that the intention of the creator is not spoiled.

Further, when the URL of the document is changed, it can be dealt with only by changing the conversion table, and it is not necessary to rewrite individual documents, so that efficient document management becomes possible. Furthermore, since there is no need to make any changes when the computer C1 accesses a document, the present invention can be continuously introduced even if a document access service has been provided so far.

FIG. 7 is a diagram showing a configuration of an information relay conversion device according to another embodiment of the present invention. The information relay conversion device 7 of the present embodiment includes the computer C1 and the computer C
, A request relay unit 701, a document file receiving unit 702, and a document determining unit 7.
03, a replacement processing unit 704, a conversion table 705, and a document file transmission unit 706. In the present embodiment, the address that the computer C2 discloses to the outside for document access is A2, the port number is P2, and the document name is [D2]. Then, when accessing this service from the outside, it is accessed by (A2, P2, D2).

The address on the network of the information relay converter 7 shown in FIG. 7 is A4, and the port number of the relay service is P4. Then, when the computer C1 wants to access the information on the computer C2 via (A2, P2, D2) via the information relay conversion device 7, the computer C1 uses (A4, P4, [A2, P
2, D2]). When the request relay unit 701 of the information relay conversion device 7 receives this, the port number has been changed to P3 as described above, so that [A2, P2, D
2], (A2, P3, D2) is obtained, thereby accessing the computer C2. In computer C2,
The corresponding document D2 is read, and the document file receiving unit 70
Send to 2. In the following processing, the document D 'is transmitted to the computer C1 by the same processing as in the embodiment described with reference to FIG.

As described above, in this embodiment, the same effects as in the embodiment described with reference to FIG. 2 can be obtained without making any changes to the setting of the transmitting computer C2. By preparing a conversion table on each of the receiving sides, it is possible to reflect the preferences of each user. That is, for example, for the word "information search", a certain user links with the information search service I1,
Another user can link to the information retrieval service I2.

[0039]

As described above, according to the present invention,
The information request from the receiving computer is relayed to the transmitting computer, and the information from the transmitting computer in response to the information request is received from the transmitting computer. If the information is text information, the correspondence between the search character string and the replacement character string Is converted from the text information to the replacement character string by using the conversion table storing the text information and transmitted to the receiving computer. Therefore, for each document managed by the transmitting computer, the individual document Hyperlinks can be defined in a unified manner without bothering the user. In this case, if the document creator defines a different hyperlink for the same phrase, the definition takes precedence. There is no loss of intention. Further, when the URL of the document is changed, it can be dealt with only by changing the conversion table, and it is not necessary to rewrite individual documents, so that efficient document management can be performed. Further, since there is no need to make any changes to the document request method, the present invention can be introduced continuously even if a document access service has been provided. Further, when the present invention is applied to the receiving computer, the same effects as described above can be obtained without making any changes to the settings of the transmitting device. By preparing a conversion table on each receiving side, it is also possible to reflect the preferences of each user.
