Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an index posting device for posting an index composed of a sequence of titles of information used by an unspecified number of users, and a program used for realizing the index posting device. The present invention relates to a stored program recording medium, and more particularly, to an index posting device for improving user browsability and a program recording medium for storing a program used for realizing the index posting device.

[0002] As a result of information retrieval, it is widely used to search for necessary information from an index composed of a sequence of titles of information, such as a document directory, a file list, and an application program such as a word processor.

Conventionally, when a specific individual accesses, a method has been adopted in which the index is rearranged using the access frequency, the last access time, etc., thereby improving the browsability. However, such a method, WWW
As described above, when information is frequently updated and an unspecified number of users access the application, unsuccessful operations may occur.

Therefore, when information such as WWW is accessed by an unspecified number of users, it is necessary to construct a new technology that can improve the browsability of the users.

[0005]

2. Description of the Related Art Information is sorted according to access frequency,
Improving user operability is a simple and effective method.

For example, in Japanese Patent Application Laid-Open No. 52-132653, a dictionary for kana-kanji conversion is rearranged every time according to frequency, and kanji frequently accessed even with the same reading is preferentially output.
A technique for reducing the burden on the user has been disclosed, and is actually used in many word processors.

Also, in Japanese Patent Application Laid-Open No. 8-227419, when a symbol is input by selecting an input symbol from among the symbols to be displayed, the frequent symbol is brought to a display position where it is easy to see. There is disclosed a technique of improving the operability of a computer.

[0008]

However, these prior arts are all based on personal use. From now on, if these conventional techniques are used as they are, as in the case of the WWW on the Internet, when information is frequently updated and an unspecified large number of users access the information, the frequency alone may not work.

[0009] For example, if there is information where access is extremely concentrated temporarily, such as when a major accident occurs, the information will continue to be at a higher position forever. In the case of media such as WWW, it is necessary to consider not only the frequency of access but also the freshness (newness) of information.
The prior art does not consider this point at all.

In the case of the WWW, a recent access ranking is sometimes performed by analyzing an access log periodically and specifying a log having a high access frequency in a certain period. According to the method described above, there is a problem in that the log analysis is not effective unless logs are accumulated to some extent, and a log file is often enormous.

On the other hand, recently, as a method of managing personal documents, a super organizing method (Noguchi: “super organizing method”, Chuko Shinsho (1992)
A management method called 3)) has been proposed. This super-arrangement method is characterized in that when managing personal documents, the documents are arranged in order of last access time. However, instead of sorting documents using an index in which the last update time is recorded, a method has been proposed in which sorting can be naturally performed in the order of the last access time in a daily work procedure.

In this method, a new document is placed at the top (rightmost), and a document read once is placed at the top (rightmost). By this management method, the top (right)
, Documents that are frequently accessed (highly fresh) accumulate, and documents that are rarely accessed (low freshness) accumulate in the lower part (left side).

The advantage of the super organizing method is that not only a document with high freshness is selected, but also a document with low freshness is naturally discriminated. When organizing unnecessary documents, they should be discarded from the bottom (left side).

However, this super organizing method is a method of managing personal documents, and there is a problem if this method is applied as it is to information used by unspecified large numbers such as WWW.
For example, not everyone accesses the same information, so if one person accesses information that is rarely accessed, it will come to the top and increase the readability of many other people. On the contrary, it will be spoiled.

[0015] The present invention has been made in view of the above circumstances, and is directed to a case in which an index composed of a list of titles of information used by an unspecified number of users is posted. The purpose of the present invention is to provide a new index posting device that improves the browsability of a document, and a new program recording medium that stores a program used to realize the index posting device.

More specifically, when adopting a configuration in which an index of information used by an unspecified number of users such as a WWW document is posted, information which is frequently accessed by an unspecified number of users can be used. I want to give the title higher priority.

However, even if the total number of accesses is large,
I want information that has become less fresh to be lower. Rather than collecting logs and sorting them at regular intervals, we want to adopt a method in which the order changes naturally with each access.

Since it is intended for an unspecified number of users, some non-cooperative users may intentionally change the order of the index. Therefore, we want to make sure that the hobbies and intentions of a particular individual do not affect the overall arrangement.

It is desired to realize these from as little index information as possible without using total information such as access history and access frequency. It is an object of the present invention to provide a new index posting device that solves the above problem, and to provide a new program recording medium that stores a program used to realize the index posting device.

[0020]

FIG. 1 shows the principle configuration of the present invention. In the figure, reference numeral 1 denotes an index posting device equipped with the present invention, which displays an index composed of a sequence of titles of information used by an unspecified number of users who operate the terminal 2 on the terminal 2. When a title is selected by the user in response to the notice, information indicated by the selected title is obtained from the own device or another device and provided to the terminal 2.

The index posting device 1 of the present invention comprises an index management means 10, a first management means 11, and a second management means 12.
Transmitting means 13, detecting means 14, changing means 15
, Registration means 16, erasing means 17, and deleting means 18.

The index management means 10 manages information on an index posted on the terminal 2. The first management unit 11 manages user level information. The second management means 12 manages the last accessed user information for each index title.

The transmitting means 13 transmits the index information managed by the index managing means 10 to the terminal 2 to post the index on the terminal 2. The detecting means 14 detects whether or not the information is accessed by selecting the title of the index to be posted to the user. The change unit 15 changes the order of the titles of the index posted to the user when the detection unit 14 detects an access.

When there is a request to add new information, the registration means 16 adds a mark indicating that the information is new and registers the title of the information in the index. Erasing means 17
The mark indicating newness added by the registration means 16 is deleted. The deletion unit 18 deletes a title from the index.

Here, the transmitting means 13 / detecting means 14 / changing means 15 / registering means 1 of the index posting device 1 of the present invention.
6 / erasing means 17 / deleting means 18 are specifically realized by a program.
The present invention is realized by being stored in a floppy disk or the like, or stored in a disk such as a server, and then installed in the index posting device 1 and operated on a memory.

In the index posting device 1 of the present invention configured as described above, when the transmitting means 13 posts the index on the terminal 2, the information may be accessed by selecting the title by the detecting means 14. When detected, the changing means 15
Changes the order of the titles in the index by exchanging the position of the selected title with the position of one or more titles positioned higher than the title.

When adopting this index title change processing configuration, the changing means 15 specifies the user level information in accordance with the management data of the first management means 11, and according to the specified user level information. To determine the number of titles to be exchanged.

The changing means 15 determines whether or not the same user continuously selects the same title in accordance with the management data of the second management means 12, and when it is determined that the same title is to be continuously selected, Process not to change the position of the selected title.

When the index has related information in association with the title, the changing means 15 performs processing to change the position of the related information when the position of the title is changed.

Further, when adopting this title rearrangement processing configuration, when there is a request for adding new information, the registration means 16 adds a mark indicating that it is new to the middle position of the index specification. When the title of the information is registered and the index overflows due to the registration process, the deleting unit 18 deletes the lowest-order title of the index.

The erasing means 17 erases the new mark added to the title when the title to which the new mark is added is skipped according to the change processing of the changing means 15. I do.

As described above, in the index posting device 1 of the present invention, when information is accessed by selecting an index title to be posted to an unspecified number of users, the position of the selected title is displayed. By exchanging the number of title positions specified by the user level information positioned higher than the title, the order of the titles in the index is changed, and at this time, when the same user continuously accesses the same information, Use a configuration that does not execute the change. Thus, the title of frequently accessed information can be posted at a higher position in the index without intentional access or the like, without using aggregated access information, and considering the importance of the user. Become like

When this configuration is adopted, the title of the newly registered information is registered while adding a mark indicating that it is new to the middle position of the index, and the title of the new information is registered. When a title with a mark is skipped by the title rearrangement process, the mark added to the title is deleted to manage the freshness of information. As a result, it is possible to post a title of information having high freshness at a position higher in the index while considering the freshness of information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail according to embodiments. FIG. 2 illustrates an embodiment of the present invention.

Referring to FIG. 1, reference numeral 1a denotes a document index server provided with the present invention, which provides a plurality of terminals 2 operated by an unspecified number of users and document information via a network 4 such as the Internet. A document index which is connected to a plurality of document servers 3 and is composed of a sequence of titles of documents provided by the document server 3 is posted on the terminal 2, and the user selects a document title in response to the posting. Then, the document pointed to by the selected document title is obtained from the document server 3 and is provided to the terminal 2.

The document index server 1a according to the present invention includes a document index 10 for managing document index information in order to realize the present invention.
0, a document number table 101 that manages the number of documents registered in the document index 100, a user management table 102 that manages user level information, and a document index management mechanism 103 that executes management processing of the document index 100. Is provided.

Here, the document index management mechanism 103 is specifically constituted by a program, and this program is installed via a floppy disk, a line, or the like.

FIG. 3 shows an embodiment of the data structure of the document index 100, and FIG. 4 shows an embodiment of the data structure of the user management table 102. The document index 100 according to the embodiment of FIG. 3 includes a document title of a document provided to the user, a URL of the document server 3 that manages the document indicated by the document title, and an ID of a user who last accessed the document indicated by the document title. And a flag indicating whether or not the document indicated by the document title is a new document, and a URL of the document server 3 which manages a related document of the document indicated by the document title. In addition, the ID of the user who registered the document indicated by the document title may be managed.

Here, "IDX" in FIG. “URL” indicates the URL (document ID on the network) of the document index 100. “Max (IDX)” indicates the maximum number of records registered in the document index 100.

On the other hand, the user management table 102 according to the embodiment of FIG. 4 manages the correspondence between the ID of the user who operates the terminal 2 and the user level assigned to the user. This user level is to be registered by the administrator of the document index server 1a, and is defined in four stages from the highest user level A to the lowest user level D, for example.

Here, when the user accesses for the first time, the default level (for example, user level C) is set. Further, when it is determined that the user is a malicious user, the administrator lowers the level, and when the user is a good user, raises the level, so that the administrator can maintain the order of the document index to some extent.

As will be described later, the document index management mechanism 103
Is used when a user accesses a document.
The document title of the frequently accessed document is displayed in the upper position of the index of the document posted on the terminal 2 by exchanging the record of the accessed document having 0 with the position of the record located at a higher position. The user level managed by the user management table 102 defines the number “dn (UID)” of records to be exchanged at this time.

For example, at the user level A, "d
n (UID) = maximum number of documents in document index 100 ", at user level B," dn (UID) = 2 ", at user level C," dn (UID) = 1 ", malicious user At the user level D, "dn
(UID) = 0 ".

At the time of such a configuration, the following three types of protocols are prepared. GET (URL) This is a protocol for acquiring the document index 100 and documents. The terminal 2 receives the “GET (IDX By issuing the GET command “URL)”, the document index 100 is acquired, and the index of the document composed of the sequence of the document titles is displayed on the display screen according to the document index 100.

Further, the document index server 1a transmits the “GE
T (DOC By issuing a GET command “URL)”, the document indicated by the document title selected by the user is acquired from the document server 3. Here, "DOC UR
“L” indicates the URL of one document in the document index 100.

GET2 (IDX URL, DOC U
RL, USER ID) This is a protocol for acquiring a document from the document server 3. The terminal 2 specifies the URL of the document index 100 and the URL of one document in the document index 100 to specify the document to be obtained, and issues the GET2 instruction to obtain the document. . Here, "USER ID "
Indicates the ID of the viewing user.

REGISTER (IDX URL, D
OC URL, TITLE, USER ID) A protocol for registering a document in the document index 100. The terminal 2 stores the URL of the document index 100 to be registered.
And the URL of the document to be registered (DOC By specifying the URL, the document title of the document to be registered, and the ID of the user to be registered, and issuing this REGISTER command, the document is registered in the document index 100.

FIGS. 5 and 6 show an embodiment of a processing flow to be executed by the document index management mechanism 103 when a user accesses a document. FIG. 7 shows a processing flow when the user registers a new document. FIG. 3 illustrates an embodiment of a processing flow to be executed by the document index management mechanism 103. FIG.

Next, according to this processing flow, the operation processing of the embodiment configured as described above will be described. First, the document index management mechanism 1 executed when a user accesses a document in accordance with the processing flow of FIGS. 5 and 6.
03 will be described.

When the user accesses a document provided by the document server 3, the terminal 2 operated by the user operates the “GET (IDX URL), the document index management mechanism 103 is issued when this GET instruction is issued.
As shown in the processing flow of FIGS. 5 and 6, first, in step 1, by transmitting the information of the document index 100 shown in FIG. Is displayed.

Here, of the information of the document index 100 shown in FIG. 3, what is displayed on the display screen of the terminal 2 is as follows.
A document title, flag information indicating whether the document is a new document, and a URL of a related document. The URL of a related document may be displayed in the form of a URL or indirectly using a document title. Other information need not be displayed on the display screen, but may be displayed.

When the index of the document is displayed on the display screen, the user selects the document title of the document that he / she wants to access from the index, and in response, the terminal 2 displays the “document title” indicated by the selected document title. DOC URL ”and specify“ GET2 (IDX URL, DOC
URL, USER ID)), the document index management mechanism 103 determines in step 2 that the GET2
Wait for instruction to be issued.

In this step 2, the GE issued by the terminal 2
When the issuance of the T2 instruction is received, the process proceeds to step 3 to refer to the user management table 102 and to execute “USER” designated by the issued GET2 instruction. It is determined whether or not “ID (abbreviated as UI in the figure)” indicates a malicious user.

When it is determined in step 3 that no malicious user is indicated, the process proceeds to step 4 where "DOC 2" specified by the issued GET2 instruction is executed.
It is determined whether or not “URL (abbreviated as DU in the figure)” indicates the top document (that is, the top document title).

If it is determined in step 4 that the document is not the top document, the process proceeds to step 5 where the "DOC" managed by the document index 100 is displayed. U
RL ", the last access user ID (abbreviated as LU in the figure) is obtained, and the user management table 1
02 with reference to “USER” designated by the issued GET2 instruction. By specifying the user level indicated by the “ID”, the above-mentioned “dn (UID)” is acquired.

Subsequently, in step 6, the last access user ID acquired in step 5 and the “USER” specified by the issued GET2 instruction ID ”is determined.

If it is determined in step 6 that the two do not match, the process proceeds to step 7 and
"DOC" specified by the issued GET2 instruction UR
"Dn (UID)" records located at the upper position of "L" are processed, and it is checked whether a new flag is added to those records. If the new flag is added, Deletes it from the document index 100.

Subsequently, in step 8, the issued GET
"DOC" specified by two instructions The arrangement order of the document index 100 is changed so that the position of the “URL” is positioned above “dn (UID)” records located at the higher position, and the “GET2 instruction specified by the issued GET2 instruction” U
SER The last access user ID is updated according to the “ID”.

Subsequently, at step 9, the issued GET
"DOC" specified by two instructions The position of the URL information of the related document held by “URL” is changed in accordance with the position exchange processing in step 8.

Subsequently, the process proceeds to step 10 (the processing flow of FIG. 6), where "DOC" designated by the issued GET2 instruction is executed. URL ”and specify“ GET (DOC) ”for the document server 3. URL) "
The "DOC A transmission request for the document specified by the “URL” is issued.

Subsequently, at step 11, a document sent from the document server 3 is received in response to the issued transmission request, and when it is received, the process proceeds to step 12, at which the received document is issued with a GET2 instruction. Send to the original terminal 2,
The process ends.

On the other hand, according to the judgment processing of step 3, “USER” designated by the issued GET2 instruction ID "
Is determined to indicate a malicious user, and according to the determination processing of step 4, the “DOC2” specified by the issued GET2 instruction When determining that the “URL” indicates the top-level document, and according to the determination processing of step 6, “USER” specified by the issued GET2 instruction.
When it is determined that the “ID” matches the last access user ID, the process immediately proceeds to step 10 where “DOC” specified by the issued GET2 instruction is executed. URL ”and specify“ GET (DOC) ”for the document server 3. U
RL) ”, the“ DOC ” A document designated by “URL” is acquired, and the document is transmitted to the terminal 2 that has issued the GET2 instruction.

As described above, the document index management mechanism 103
When a user accesses a document, as shown in FIG. 8, the document index 100 exchanges a record of the accessed document with a position of a record located at a higher position, thereby obtaining a frequently accessed document. The document title is displayed in the upper position of the index.

At this time, by determining the number of records to be exchanged according to the level of the user, the exchange process is performed in consideration of the importance of the user. By not performing this exchange process for the access of a malicious user, the exchange process is performed so as to prevent malicious mischief, and even when the same user continuously accesses the same document, the exchange process is not performed. By not performing
It processes to avoid the tendency of personal access.

When the newly registered document is specified using a mark, the freshness of the document is displayed.
When a document located below the document is accessed, the mark is deleted, thereby processing to easily and accurately manage the freshness of the document.

Next, according to the processing flow of FIG.
Document index management machine executed when a new document is registered
The processing of the structure 103 will be described. User adds new document
Is registered, the terminal 2 operated by the user operates as described above.
"REGISTER (IDX URL, DOC UR
L, TITLE, USER ID) is issued.
When the REGISTER instruction is issued, the document index management
First, as shown in the processing flow of FIG.
First, in step 1, refer to the user management table 102.
By doing so, it is specified by the issued REGISTER instruction.
"USER ID "indicates a malicious user?
To determine if it indicates a malicious user
To go to step 3, the REGISTER command
Notify terminal 2 that issued the instruction that registration is not possible, and terminate the process.
Complete.

On the other hand, if it is determined in step 1 that no malicious user is indicated, the process proceeds to step 2
To “DOC” specified by the REGISTER instruction.
It is determined whether or not the “URL” has already been registered in the document index 100, and when it is determined that the “URL” has been registered, the process proceeds to step 3, where registration to the terminal 2 that has issued the REGISTER command is impossible (registration is not possible). Is completed), and the process ends.

On the other hand, in the judgment processing of step 2, REGI
"DOC" specified by the STER instruction URL ”is the document index
If you decide that you are not registered to
Proceeding to step 4, managed by the document number table 101
Record that the number of existing documents can be registered in the document index 100
Determine whether the number matches the number “max (IDX)”
You. That is, whether the document index 100 is full
It is determined whether or not.

In the judgment processing of this step 4, the document index 1
When it is determined that 00 is full, the process proceeds to step 5 to delete the lowest record of the document index 100 so that a new record can be added. When deleting from the present apparatus, a method of storing it in an existing separate database or the like may be adopted.

When the processing in step 5 is completed, or when it is determined in the determination processing in step 4 that the document index 100 is not full, in the subsequent step 6, the document index 10
A process is performed to shift lower records one by one from the prescribed n-th record located at the intermediate position of 0 one by one.

Subsequently, in step 7, “TITLE (document title)” / “DOC” specified by the issued REGISTER instruction is placed at the position of the n-th record emptied by the processing in step 6. URL (URL of the document indicated by the document title) "/" USER ID (registered user ID) ", and a new flag is registered to indicate that the record to be registered is new, and the process ends. Here, if the URL of the related document is specified by the REGISTER command, it is also registered.

Thus, the document index management mechanism 103
When a document registration request is issued from a user, as shown in FIG.
By registering at the specified intermediate position of 0 (for example, the 10th position from the highest position), the document title of the document with high freshness is processed to be displayed at the upper position of the index together with the new mark. is there.

According to the processing executed by the document index management mechanism 103 described above, the display screen of the terminal 2
When an index composed of a list of document titles as shown in the upper part of FIG. 10 is displayed, if the user accesses a document by selecting a lower-level document title,
As shown in the lower part of FIG. 10, the position of the selected document title is exchanged with the position of the higher-order document title, so that the document title of the frequently accessed document becomes higher in the index. .

Here, FIG. 10 shows an example in which the "college robot championship" is accessed and the order moves to a higher rank. At this time, the “New” mark of “College Robot Championship” indicating the newness remains as it is.

By applying the document index management mechanism 103 to the index of information other than documents, an index composed of a list of information titles as shown in the upper part of FIG. 11 is displayed on the display screen of the terminal 2. When the user accesses a document by selecting an information title located at a lower level, the selected information title exchanges a position with an information title located at an upper level as shown in the lower part of FIG. As a result, the information title of the frequently accessed document comes to be positioned at the top of the index.

Here, FIG. 11 shows an example in which “about the speed of the PCI bus” is accessed to move the order higher. At this time, the New mark of “business trip Qand A” indicating that the device is new is “PCI
It will be erased by jumping to "About bus speed".

The present inventor has disclosed in Japanese Patent Application No. 8-281940 a device configured to share a document in a group and browse the shared document in various views. The present invention is added to this device. Will also be effective.

That is, as shown in FIG. 12, a document specified by a user is copied to a server, and an index is created using information in the document. Then, apart from the groupware index, the document index function of the present invention is added to create a document index on the server. The resulting view is called a group view. With this device configuration, the browsability of the shared document can be greatly improved.

The present inventor has disclosed a method for semi-automatically generating a hierarchical index of a network document in Japanese Patent Application No. 10-176749, but adding the present invention to this invention is also effective.

That is, in the hierarchical index, an index is created by a hypertext based on the keyword hierarchy. Each hypertext contains a list of documents containing keywords. The user can reach the desired document simply by clicking the keyword. At this time,
As shown in FIG. 13, by using the present invention, it is effective to automatically rearrange the document list in each hypertext according to the access status of the user.

The present invention has been described with reference to the illustrated embodiments.
The present invention is not limited to this. For example, the upper position of the index referred to in the embodiment means the position on the starting side of the index. For example, when the index starts from the right end, the upper position means the position on the right side.

In the embodiment, the case where a document is accessed has been described as a specific example. However, the present invention can be applied to a case where various information such as a program is accessed.

[0083]

As described above, according to the present invention, the index of information accessed by an unspecified number of users is automatically changed by changing the index order each time the information is accessed. Can be separated.

In the present invention, the accessed information is exchanged with the index position of the information located higher than the accessed information without recording the access history or totaling the access frequency and the like, so that the number of accesses increases. It is easily realized that the order of the index is higher.

In the present invention, in the index change processing, the order of replacement is changed according to the user level, so that the index update degree can be adjusted by the user and the administrator can intentionally change the index. Can be changed.

In the present invention, when the same user repeatedly accesses the same information, the index order is maliciously changed, or the index order is changed due to personal tendency. In addition to being able to prohibit inconvenience, it is also possible to set so that the index cannot be changed for a specific user.

In the present invention, by limiting the number of information registered in the index, unnecessary information can be automatically deleted from the index. And in the present invention,
New information is marked and placed in the middle of the index, and when the order is lowered by index exchange, the mark is erased so that the freshness of the information can be clearly indicated. Also, by erasing the mark without using the date and time of creation of the information or the elapsed time, old information can be selected naturally and easily.
