Description

[Detailed Description of the Invention] [Summary] The purpose of this invention is to reduce as much as possible the effort and time that readers spend searching for documents regarding a document search control method in a document search system, especially a hypertext system. An importance calculation stage that calculates the importance of the document data searched in relation to document data, and the searched document data are arranged in the order of importance calculated by the importance calculation means, corresponding to the document data being displayed. The apparatus is configured to include a search document recording means for recording the search document data, and a record document search means for searching document data recorded by the search document recording means corresponding to the document data being displayed.

[Industrial application field]

The present invention relates to a document retrieval system, and particularly to a document retrieval control method in a hypertext system.

In recent years, hypertext systems have been put into practical use as one type of document retrieval system.

In hypertext systems, two types of search means are provided to search for a desired document: one for specifying keywords and one for specifying links.

Even in this type of hypertext system, it is desired that the user be able to search for a desired document as quickly as possible.

[Conventional technology]

FIG. 6 is a diagram showing an example of a conventional hypertext system, FIG. 7 is a diagram showing an example of document management data in FIG. 6, and FIG. 8 is a diagram illustrating links between documents. .

In FIG. 6, the storage unit 2 contains document data 21 related to a plurality of documents D (individual documents are expressed with subscripts such as Do, Dl, B2, etc., the same applies hereinafter), and document management data 22.
is stored.

As shown in FIG. 7, the document management data 22 includes a document number N given to each document, a title M of the document, a number of lines G constituting the document, and a number of digits C1 indicating the number of characters per line. In addition to the keywords used to search for a document, the number of links provided between the document and other related documents, the position of the search starting point for each link L (hereinafter referred to as button B), It includes the size and the link destination indicated by the document number N of the other document retrieved by the link L.

For example, in FIG.
19191), a hypertext-related document D was created as another document that readers might wish to refer to.
+ (R Overview of Hypertext), document number N, = 2149132), and document D2 related to transparent tablets (technical report ``Capacitively Coupled Transparent Tablet,'' document number N2 = 1949272), The corresponding words (“hypertext” and “transparent tablet”) in document B0 are defined as buttons B1 and B2, respectively, and button Bl (=r
Hypertext) start position (number of lines G1, number of digits 01
) and the number of occupied lines x number of digits of the button B2 itself, and the document number N of the document DI at the link destination, (=2149
132), and similarly store the start position (
The number of lines (02, number of digits CZ) and the number of occupied lines x number of digits of button B2 itself are stored, and the document number N of document D2 is stored in the link destination.
2 (=1941272) and further documents. When searching for and displaying document data 21° on the screen of the display 3, buttons B and B2 are displayed by surrounding each word or phrase with a rectangular frame, for example.

On the other hand, documentation. If a reader of , with document data 21° displayed on the screen of Display 3, wishes to disclose reference materials related to the phrase "hypertext," he can use the search command, since there is a button display for the same phrase. Instead of inputting , the user instructs the button B1 using the pointing device 5 such as a mouse or a transparent tablet.

When the processing unit 1 receives the instruction signal from the pointing device 5, it activates the link search unit 12, and the activated link search unit 12 searches the document data 21. , and recognizes that the received instruction signal instructs within the area specified by the position and size of the link L1, the document specified by the link destination (-document number Nl) Extracting document data 211 related to D1 from the storage unit 2,
It is displayed on the screen of the display 3 instead of the document data 21°.

Furthermore, when the reader of the document D0 specifies the button B2 using the pointing device 5 to investigate the phrase "transparent tablet," the link search unit 12 receives the instruction signal from the pointing device 5 and the document management data 22.
By comparing the link L2 in ゜, it becomes possible to immediately display the document data 21□ regarding the document D2 on the screen of the display 3.

In addition, when the reader searches for a word that is not displayed as button B (for example, rlsDNJ), when the reader inputs a search command specifying the keyword (for example, rlsDNJ, etc.) from the keyboard 4, the search command processing unit 11 in the processing unit 1 is activated, and as is well known, each document management data 22 in the storage unit 2 is sequentially referred to, and the specified keyword (=
rlSDNJ, etc.), display the number of corresponding documents on the screen of the display 3, and after the reader repeats the above process, inputs a display request command for a specific document. The corresponding document data 21° is displayed on the screen of the display 3.

[Problem to be solved by the invention]

As is clear from the above explanation (in conventional hypertext systems, the creator of document D0 needs to provide links L1 and L2 between documents D1 and D2 that are expected to be requested by readers in advance). , which requires a great deal of effort.

Therefore, there is a limit to the scope in which the creator prepares the link L, and there are cases in which the creator takes the trouble to provide the link L, or D2 is of no use value to the reader, and is rather concerned with content for which the link L is not provided. There are not always cases where an investigation is necessary, and in such cases, the reader needs to use a search command to search for the desired document D, which may cause the reader to spend a great deal of effort and time.

The present invention aims to reduce as much as possible the effort and time that readers spend searching for documents.

[Means to solve the problem]

FIG. 1 is a diagram showing the principle of the present invention.

In FIG. 1, 100 is a document search system to which the present invention is applied.

200 is a document retrieval system 10 according to the present invention. This is one means for calculating importance provided in O.

300 is a search document recording means provided in the document search system 100 according to the present invention.

400 is a recorded document search means provided in the document search system 100 according to the present invention.

[Effect]

The document search system 100 stores a plurality of document data, searches for and outputs specified document data.

The importance calculation means 200 calculates the importance of document data retrieved in relation to the document data being displayed.

As the degree of importance, since it is assumed that a reader will take a sufficient amount of time to refer to a valid document, for example, the value obtained by dividing the document reference time by the number of lines is taken into consideration.

The retrieved document recording means 300 arranges and records the retrieved document data in the order of importance calculated by the importance calculation means 200.

The recorded document search means 400 searches for document data recorded by the searched document recording means 300 corresponding to the document data being displayed.

Therefore, in the search document recording means, all the documents that the document reader has searched once are arranged and recorded in the order of importance, and when the reader wishes to search for reference materials, the document search If you first refer to the search document recording means, the possibility of finding the desired document is extremely high, and compared to searching by keyword, the time and effort are dramatically reduced, and the convenience of the document retrieval system is improved. improves.

It is assumed that importance level Pb=4.3 seconds/row, etc. is stored.

The process of creating the search history table 23 will be described later.

In FIGS. 2 to 5, 7 and 8, the reader is shown documents stored in the storage unit 2.

("Document search method", document number N, = 3219
191) and is displayed on the screen of the display 3 (step 511 in FIG. 4), and if it is necessary to search for a phrase consisting of (for example, rlsDNJ) (step 512), first select the search target. Check whether button B is provided for the phrase (step 513), and if button B is provided, specify the corresponding button B using pointing device 5 (step 51).
4) The link search unit 12 immediately searches for the document data 21 that are linked.

In addition, if button B is not provided for the research target word, the reader may press keyboard 4 or pointing device 5.
When an instruction (command) to display the search history table 23 is input (step 515), the processing unit 1 starts the search history table processing unit 14, and the activated search history table processing unit 14 displays the document data 21° being displayed. The search history table 230 corresponding to

The reader checks whether the desired reference material exists in the search history table 23 (step 517), and if the desired document is detected, the reader inputs the document number N of the document. (Step 518), the desired document data 21 is immediately retrieved.

The desired reference material is the search history table 23. If it does not exist, the reader inputs a search command specifying a desired keyword (for example, r-I 5DNj ), as is known in the art (step 519).

The processing unit 1 that has received the search command (STE 521 in FIG. 5) starts the search command processing unit 11 in the same manner as described above, sequentially refers to each document management data 22 in the storage unit 2,
Search the document management data 22 that includes the specified keyword (=rlsDNJ) (Step 522), and display the number of matching documents on the screen of the display 3 (Step 523).
, After the reader repeats the above process, a specific document D, ([
When the display request command for broadband 15DNJ, document number Nt=4276728) is entered manually (step 524), the corresponding document data 21. is displayed on the screen of the display 3 (step 525), and the search history table creation unit 1
Start 3.

The activated search history table creation unit 13 generates the document data 21.
starts measuring the time T, which is referenced by the reader (step 826).

When the reader finishes referring to the document Dj and starts referring to it, another document Dj (where j
When a search command is input to refer to ≠i) (step 327), the search command processing unit 11 notifies the search history table creation unit 13 that the display of the document data 21 has ended.

The search history table creation unit 13 that received the display end notification at time T
, to finish the measurement of , step 528), then calculate the number of lines G of the document from the document management data 22i corresponding to the document data 21i being displayed (step 529), and then start the importance calculation unit 131. , the measured time T, and the determined number of lines G, the importance level Pi (=T+Gi, for example, 2.7 seconds/line) is calculated (step 530).

Next, the search history table creation unit 13 generates the currently displayed document data 21. From the document management data 221 corresponding to
5DNJ) and calculated importance p, (=2.7
seconds/line) and is added to the end of the search history table 23° corresponding to the document data 21° displayed in step Sll (step 531).

Subsequently, the search history table creation unit 13 rearranges the documents stored in the search history table 23° in descending order of importance P (step 532). If the addition of documents exceeds the storage capacity allowed for the search history table 23゜, the documents with the lowest importance level P are deleted, and the search history table 23゜ is brought within the permissible storage capacity. (Step 533)
).

When the process of creating (updating) the search history table 23° is completed as described above, the search history table creation unit 13 notifies the search command processing unit 11 to that effect.

Thereafter, the search command processing unit 11 executes search processing for other documents D based on the search command input in step S18 (step 534).

As is clear from the above description, according to the present embodiment, the document D, which the reader has searched as reference material, is recorded with the importance level P8 calculated and arranged in the search history table 23° in the order of the importance level P. Therefore, even if button B is not provided for the search target term, there is a possibility that the desired document can be immediately searched from among the documents recorded in the search history table 23, and the search command The chances of searching for document D are reduced.

Note that FIGS. 2 to 5, 7, and 8 are merely examples of the present invention, and for example, the document search system 100 to which the present invention is applied is limited to the illustrated hypertext system. Although many other modifications may be considered, the effect of the present invention remains unchanged in any case. Further, the documents to which the present invention is applied are exemplified documents. The present invention is not limited to D2, D1, etc., and many other modifications may be considered, but the effects of the present invention remain the same in any case.

〔Effect of the invention〕
