Abstract

PURPOSE:To easily register and retrieve the document data by using a part of the contents of the handwritten memorandums or the document data received from a tablet as a retrieving key and at the same time giving a hierachical structure and a sequence relation to the retrieving key. CONSTITUTION:When the document data is confirmed and corrected, a registration operator gives a retrieving key to the document data and registers it. That is, a handwritten retrieving key is written into an input/display area 202 of an input part. Furthermore a hierarchical structure containing the big headlines 301, the crossheads 302, the subheads 303, the titles 304, etc., is added to the retrieving key. Then a sequence relation is secured between retrieving keys within the same hierarchy. As a result, the document data can be effectively arranged and retrieved.

Description

Detailed description of the invention (Technical field to which the invention pertains) The present invention relates to a personal document retrieval device that stores, retrieves, and displays one document data, and a document retrieval method for easily registering and retrieving document data. It is related to.

(Prior Art) An electronic filing device is a typical device for storing and searching document data. This electronic filing device can store a large amount of document data and is designed to be shared by multiple people, so the search method is to assign a search key as a character code using the keyboard. By doing so, it is possible to perform detailed searches for various relational operations in relational databases.

However, when adding a search key, a series of operations such as keyboard input and kana-kanji conversion are required, and search keys other than character codes (images and graphics) cannot be added. Be flexible. Furthermore, the above-described search method for electronic filing devices cannot be used for small document search devices that do not have a keyboard.

In addition, there are small document search devices such as personal computers, word processors, and electronic notebooks, but most of them use a keyboard to assign search keys using character codes, which is the method described above. Similar problems arise with electronic filing devices.

There is a device that integrates a display and a tablet and does not have a keyboard, but the search method is to recognize the kana characters input from the tablet, convert the results to kana-kanji, and use the code data as a search key to search one document data. It uses a method of registering and searching for information, and as with the electronic filing device mentioned above, it aims to be easy and flexible in terms of usability.

(Object of the invention) The object of the present invention is to solve the drawbacks of conventional document retrieval methods,
An object of the present invention is to provide a search method for easily registering and searching one document data for a document search device for personal use.

(Structure of the Invention) (Characteristics of the Invention and Differences from the Prior Art) The present invention utilizes an input display mechanism that integrates a flat display and a tablet to directly input handwritten memos or part of the content of document data from the tablet. The most important features are that the search key is used as a search key, and that the search key has an NM groove structural order relationship.

The assigning method is different from the search keys using character codes in conventional electronic filing devices and document search devices such as personal computers. Furthermore, by providing search keys with a hierarchical structure and an order relationship, the present invention allows searches by displaying a list of search keys according to the hierarchical structure, sequential searches of documents using order relationships, and searches by specifying order positions. The difference is that it is simple and has sufficient search operation functions as a personal document search method.

FIG. 3 is a diagram showing an example of a hierarchical structure of search keys.
This is an example in which the search keys are three heading keys (large heading, medium heading, and small heading) and a title key.

FIG. 4 is a diagram for explaining a search method when the hierarchical structure of search keys is as shown in FIG. 3.

FIG. 5 is a diagram showing an example of the structure of a database management table for managing document data in the control section 8 of FIG. 1, and is an example where the hierarchical structure of search keys is as shown in FIG. 3.

Embodiments of the method of the present invention will be described below with reference to FIGS. 1 to 5.

First, an input document to be registered is inputted from the input section (B) 3 in FIG. If the input document is already written on paper, such as a magazine or literature, this input section (
B) 3 is constructed by scanning or the like, and in the case of a document in character code format created with a personal computer or word processor, it is constructed by the personal computer or word processor itself.

The document inputted from the input section (B) 3 is transferred to the screen processing section 5 via the bus 6 by the control section 8 activating the transfer control section 7 . In this screen processing section 5, if the document data inputted from the input section (B) 3 is in code format, such as input from a personal computer, etc., it is converted into dot-bang format, If the image is already in the dot pattern format, the image is displayed on the display section 2 without any conversion processing.

The registrant instructs the input section (A) 1 to enlarge, reduce, scroll, rotate, etc., confirm the input document data,
Arrange the format of document data. The instruction information is analyzed by the control section 8 based on the position information specified by the tablet and sent to the screen processing section 5, where image processing is performed according to the instruction information.

This image processing in the screen processing section 5 is executed at high speed to improve the man-machine interface. Confirmation of document data,
When the modification is completed, the registrant assigns a search key to the document data and registers it. The method of assigning and registering a search key will be explained below.

As shown in FIGS. 2(a) and 2(b), an input/display area 202 on the display screen for writing a search key is determined in advance. As the method of assigning the search key, there is a case where the registrant assigns the key by hand as shown in Fig. 2(a), and
This can be divided into cases where a part of the document shown in FIG. 2(b) is assigned as a key.

In the former case (FIG. 2(a)), the search key is given by handwriting a doublet in the input/display area 202 of the input section (A) 1. Then, in order to confirm the input result, the coordinate value data string corresponding to the handwriting of the handwriting key is sent to the screen processing section 5 through the control section 8, where it is converted into a dot pattern, and the input/display area 202 of the display section 2 ( The echo will be displayed in the same place as when inputting. The handwritten key can be freely assigned by the registrant, and can be either text or graphics.

In the latter case (FIG. 2(b)), first, mark the part of the document data display area 201 displayed on the display unit 2 that you want to use as a search key in a rectangular area as shown in FIG. 2(b). Specify in input section (A) 1 as . A rectangular area can be created by specifying the upper left and lower right points of the rectangular area using a tablet, or by manually enclosing the area to be used as a search key on a tablet, and then calculating a circumscribing rectangle from the coordinate value data string input in the control unit 8. This can be determined by a method such as finding a rectangular area.

When the rectangle specification is completed in this way, the control unit 8 requests the screen processing unit 5 to instruct copying based on the specification information, and inputs and displays the contents of the rectangular area in the specified document on the display unit 2. It is transferred to area 202 and the specified result is displayed.

At this time, the search key information within the rectangular area is enlarged or reduced and displayed depending on the size of the input/display area 202.

In addition, the control unit 8 automatically assigns a keyword to the search key created as described above, and thereafter manages the database using this keyword number (search key ID). The control unit 8 automatically assigns an integer value such as 1, 2, 3, . . . and uses this value as a search key ID. Automatic assignment of keywords is necessary when keywords based on character codes are not used as in the present invention.

As the search keys, as shown in the example of the hierarchical structure in FIG. 3, the main heading 30I, the middle heading 302. Subheading 303
．． By providing a hierarchical structure like the title 304 and further ordering search keys within the same hierarchy, document data can be organized and searched efficiently. In particular, by ordering the search keys, it is possible to assign page numbers to the entire file and to each layer, and as described later, in addition to searching by search keys, it is also possible to search by specifying the order position based on the page number. Become.

In the example shown in FIG. 3, the title 304 is the lowest search key and corresponds to the document 305 (consisting of multiple pages), which is the smallest structural unit. When registering a search key in a desired hierarchy, use the search method described below to display a list of search keys that have already been registered in the relevant hierarchy.
It can be registered by specifying the order relationship at the same time, such as by inserting a new search key between registered search keys. When the search key assignment is completed as described above, the control unit 8 updates the database management table, starts the transfer control unit 7, and displays the search key input/display area 202 in FIGS. 2(a) and 2(b). The contents are transferred to the storage section 4 via the screen processing section 5. Also, Figure 2 (,), (b)
The document data in the document data display area 201 is similarly stored in the storage unit 4.

When the database management tables in FIG. 5 are hierarchical as shown in FIG. 3, the database management tables include a large heading table 501, a medium heading table 502, and a small heading table for managing hierarchical search keys as shown. 503, a title table 504, a page table 505 that manages information regarding pages, which are the minimum units of a document, and a file management table 506 and head table 507 that manage search key information and storage addresses of the document data storage section 4. It can be configured by

Each search key is distinguished by a search key ID 500, the hierarchical structure and order relationship of each search key is expressed by link information in each table, and the order position in each hierarchy is expressed by the number of search keys and number of pages in the table. Additions and deletions of the six search keys are performed by updating the link information, number of search keys, and number of pages in each table.

The operation at the time of search will be described in FIG. 1 assuming that the search keys are hierarchical as shown in FIG. 3.

This will be explained using FIGS. 4 and 5.

When a searcher issues a search instruction from the input unit (A) 1, the control unit 8 first searches the database management table shown in FIG. Find the storage location.

Next, the transfer control section 7 is activated, and each major heading information is sequentially read out from the storage section 4, transferred to the screen processing section 5, and displayed as a list on the display section 2 as shown in FIG. At this time, depending on the relationship between the size of the stored search key information and the size of the display screen 200, the image is enlarged or reduced in the screen processing unit 5 and displayed.

When the searcher selects a desired major heading using the tablet of the input unit (A) 1, the control unit 8 obtains the search key ID 500 of the corresponding major heading key from the coordinate value data on the designated display screen, and Search processing is performed using the database management table based on the search key ID.

The search methods include: ■...Searching by sequentially displaying a list of search key information in the first hierarchy, and ■...Sequentially displaying the documents themselves belonging to the search key in the desired hierarchy according to the order relationship. ■ Specify the ordinal position within the search key of the desired hierarchy,
There is a method of searching by displaying documents in order according to the order relationship starting with the documents corresponding to the order position.

In the first method (■), medium heading information, which is a search key in the next hierarchy after the main heading key, is obtained from the database management table (Fig. 5), read out sequentially from the storage unit 4, and, like the main heading information, A list is displayed on the display section 2. This operation continues until the title key, which is the lowest search key, is displayed in a list. When the searcher specifies a desired title from the displayed list of title information, the control section 8 obtains document data corresponding to the title key from the database management table, reads it from the storage section 4, and displays it on the display section 2. In this case, as in the case of displaying a list of search key information, the screen processing unit 5 enlarges or reduces the document data and displays it according to the relationship between the size of the stored document data and the size of the display screen. To explain this using the example of FIG. 4, first, when major heading i is selected, medium headings il, i2, .・・・・・・ is displayed as a list,
When you select medium heading 1j, the next level subheading ijl
, ij2. . . . is displayed as a list, and by further selecting the subheading ijk, the lowest hierarchy titles 1jkl, 1jk2, . ... is displayed in a list. Finally, the searcher selects the title ijkm to obtain the desired document ijkm.

In the second method (■), first, the first page of the document belonging to the specified major heading key is found using the link information, the number of search keys, and the number of pages in the database management table shown in FIG. and displays it on the display section 2. Thereafter, the next document is determined from the database management table according to the order of the documents, read out from the storage section 4, and displayed, either according to the searcher's instructions or automatically when a video display is desired. Regarding the display of the above document data,
As described in the second method (2), the image is enlarged or reduced and displayed in the single-screen processing section 5.

There are two ways to display documents: a method of displaying only the first page of each document, and a method of displaying all pages, and the searcher can select one of them. The above search can be performed for each layer. In the example of FIG. 4, if this search method is selected when major heading i is specified, sentence 1i 111 of the first page belonging to major heading i will be displayed first, and then document 1112, etc. will be displayed according to the order relationship. Document 1113.・・・・・・
・are displayed in order. Similarly, if you select this search method when specifying a medium heading ij at the next level or a subheading ijk at the next level, document 1jll or document 1jkl on the first page belonging to medium heading iJ or subheading ijk will be searched first. are displayed, and then 5 documents 1j12 . Text: 2Ijj13.・・・・・・
, or document 1jk2. Documents 1jk3... are displayed in order.

Furthermore, if it is desired to reverse the display order of the documents, the documents can be sequentially displayed in the reverse order by following the link information in the database management table in the reverse direction. In the above explanation, the second search method was applied after displaying a list of major headings and selecting a desired major heading key, but it is of course possible to select the main heading before displaying a list of major headings. In this case, all documents are displayed in order starting from the first document 1111.

The third method (2) first specifies the ordinal position of the document in each hierarchy. The ordinal position can be given numerically as a page number, or it can be used to illustrate the filing status of the document.
The location can be specified by a method such as specifying the approximate position using a tablet. The specified information is sent to the control unit 8, which searches for the document closest to the specified position based on the link information in the database management table, the number of search keys, and the number of pages.
It is read out from the storage section 4 and displayed on the display section 2. Thereafter, as in the second method, document data is sequentially read out from the storage section 4 and displayed according to the order relationship.

This third method can be used in combination with the first method to perform a more effective search.

(Effects of the Invention) As explained above, according to the present invention, by assigning a handwritten memo or part of the content of document data as a search key using a tablet, it is possible to easily assign a search key. By giving keys a hierarchical structure and order relationship, it is possible to search document data efficiently by displaying a list of search keys according to the hierarchical structure, sequentially searching documents using order relationships, and searching by specifying the order position. This makes it possible to provide an excellent partial document search method with a man-machine interface.
