Abstract

PURPOSE:To display a diagram in the appropriate position of a screen by retrieving the diagram and the element which are relevant to a word and the like displayed in sentences from diagram data of a whole literature. CONSTITUTION:First, the sentences 51 are displayed in a frame. Here, an operator instructs the display 52 of a prescribed designation word by a position instruction, and a system recognizes and specifies the designation word from sentence data which is used as the source of the position and display. Data which agrees with the specified designation word is searched from diagram data. It is disposed and displayed in the appropriate position of the screen. Thus, the designation word similar to that which is displayed 52 in the frame 54 or the diagram including the display 53 of a corresponding element is arranged and displayed, and the operator can efficiently obtain information to be required as display.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic document information system, and in particular, to a display terminal thereof, which automatically displays the text of a document and related figures, tables, etc. side by side. System related.

[Conventional technology]

Using a device to display information such as a CRT display and a device such as a cursor, mouse, keyboard, or tablet to select one of the displayed items,
Systems such as the Captain System have already been put into practical use, in which when an operator selects one of the displayed items according to his or her interest, a more detailed explanation of that item is retrieved.

[Problem that the invention seeks to solve]

In the above-mentioned conventional system, the information to be displayed corresponding to the selected items is programmed in advance, and therefore the operator sequentially follows the information prepared by the system in advance only for the items that are allowed to be selected on one screen. It can be seen by To this end, the system provider must
It is necessary to prepare information to be displayed corresponding to all the selection trees, and to create data that associates the location of the information corresponding to the selection and register it in the system.

On the other hand, literature information stored in electronic databases is searched using keywords, but in this case, only the presence or absence of a relationship with a keyword is registered for an entire document. It has not yet been possible to search and display mutually related parts of the bibliography of the 2011 edition.

゛The purpose of the present invention is to electronically realize the inspection and display of related parts in a document on a terminal etc., and in particular to check and display related parts of a document, especially diagrams and their elements related to words etc. mentioned in a text. It searches for related descriptive texts, juxtaposes them, and displays them.

[Means for solving problems]

In order to achieve the above object, the present invention executes the following three steps in combination.

(1) The operator selects from among the sentences displayed on the screen.
A step of specifying a specified word by indicating a certain display part. Here, the designated word means a number 9 name of a block unit element in a diagram number 1, a technical term, etc.

(2) A step of searching for the specified word in the diagram data of the entire document.

(3) Displaying the chart at an appropriate position on the screen based on the data of the chart in which the designated word is found.

[Effect]

FIG. 2 shows an example of the screen of the terminal 6 when the present invention is implemented. Initially, the text is displayed within the frame 51. Here, the operator selects the display 52 of a specified word by specifying the position.
The system recognizes and specifies the specified word from its position and the text data that is the source of the display.

Next, the chart data is searched for a match with the specified specified word. Based on the data in the diagram or table that contains the matching data, it is displayed by arranging it at an appropriate position on the screen. As a result, as shown in Fig. 2, charts and tables containing the same specified word as the specified word displayed in 52 or the corresponding element display 54 are displayed side by side in the frame 53, allowing the operator to efficiently display the necessary information. You will get it as.

〔Example〕

Hereinafter, one embodiment of the present invention will be described according to the flowchart shown in FIG.

Step 101 is for displaying a sentence, a page of a document containing a sentence, or a portion of the page.

This is usually displayed based on instructions from the operator, and scrolling and page turning are performed. Step 102 detects when an operator looks at the displayed content and instructs instructions such as the number of a diagram or the name/number of an element that should be in the diagram in order to extract a diagram related to a certain text. It is something to do.

This is operated when the operator desires, so the system is on standby. Also, various tools are used to give instructions to the operator.

For example, you can move the cursor, press a specified key, move the mouse, press a button, etc. Direct instructions can be given using a transparent tablet superimposed on one display, or a separate tablet. The invention can be put into practice.

In step 103, the character string that the operator intended to specify is specified based on the input value indicating the position on the screen specified in step 102. Furthermore, it is determined whether the number of the diagram or the name of an element that is supposed to be in the diagram is the number specifying the element, and this is established as an indicator.

In step 104, the instruction word obtained in step 103 is searched for by scanning the list of charts, the description of the contents of the chart, or the image of the chart, and the location of matching chart data is determined.

In step 105, the chart data obtained in step 104 is expanded so that it can be displayed and displayed in one display.

After this, the process returns to step 102 and waits for the next operation.Also, the display of the text may be changed before pointing in 102, and in that case, the process returns to step 102.

The method shown in FIG. 3 described above does not require preparatory processing and can immediately process documents retrieved from the database. It also does not require a separate storage area; however, the search step 104 requires a considerable amount of processing time when specifying elements within a diagram, slowing down the response to the operator. Cheap.

FIG. 4 is a flowchart showing another embodiment for shortening this response time.

In step 110 of this figure, when a certain document is selected, the first step is to process it as a $0 stage.

The terms, instruction numbers, symbols, etc. that appear in the diagrams are found together with the predetermined positions of the data, and are recorded in the indicator word data position relationship table. If necessary, the indicator words are sorted.

Steps 101 to 103 and 105 are the same as the process in FIG. 3, and their explanation will be omitted.

Step 114 replaces step 104 in FIG. 3, and uses the instruction word data position relationship table created in step 110 to locate the diagram data corresponding to the instruction word specified by the operator. can be known. The required processing time is therefore very short.

That is, the embodiment shown in FIG. 4 is characterized by a short response time.

Here, a concrete implementation method of step 103 will be further described. It is easy to convert input information from a pointing device such as a mouse or a tablet into a coordinate system in which pixels are used as units for display. Next, in order to extract the instruction word, there are two methods of indexing depending on the display method. Namely, there are two methods: a first method in which a display image is generated from a character code string, and a second method in which data originally input as a stroke resemblance is reproduced based on that data.

In the first method, if information about the format of the text (for example, 9-line spacing between characters, vertical and horizontal framing, etc.) is known, the position in the text code corresponding to the specified point is determined from the position on the screen. It can be determined. FIG. 1 shows the configuration of one embodiment of this method. The format data and code string data of the page containing 0 sentences containing the diagram data 2 of the text data 3 of one document read from the literature database 1 are sent to the drawing processing section 4, and based on the format data and code string data are stored in the frame memory 5. The text is written. The contents of frame memory 5 are immediately displayed on CRT 6. The transparent tablet 7 is set so that the display surfaces of the tablets 6 and 6 are overlapped. When the operator specifies a certain word in the displayed text by touch, the tablet input circuit 8
The screen coordinates 81 are determined, and the touch operation is reported to the control unit.

Here, in order to identify the directive word, the character indexing unit 10 determines the line number and column position of the directive word based on the format data of the text and the screen coordinates 81, then determines the position in the code data, and then The position data is used as a read instruction word. Here, when the operator indicates the range from the beginning to the end of the instruction word, it is sufficient to pick out the character string in the corresponding code data. If the operator specifies only one point, the word will be estimated.

To do this, for example, if the indicated character is a number, the numbers that are connected before and after it, and the 1 figure that is connected to it, if there is a character such as ``table'' or ``th'', then one instruction including that. word. In another example, if the indicated character is an English letter, katakana, or kanji, the characters of the same type that precede and follow it can be combined into one indicator word.These methods are not perfect, but the estimated indicator word The operator's confirmation may be obtained by highlighting (blinking, inverting black and white, turning lines, changing the brightness level, etc.).

Now, as a second method, a method of inputting and reproducing text as an image has the configuration shown in FIG. 5 as an example.

Reads one document data from the document database 1 and stores it in the text image data storage 3 and figure surface image data storage 2.
In this case, text and figures may not be separated as image data.

At least the text image data is developed and written into the frame memory 5 by the drawing processing section 4. The contents of the frame memory are immediately displayed on the CRT 6.

A transparent tablet 7 is set over the display surface of the CRT 6, and when the operator specifies a certain word by touching it,
The zero character cutting unit 21, whose screen coordinates 81 are determined by the tablet input circuit 8, cuts out an area in the vicinity of the coordinates 81 from the frame memory 5, and further calculates the nearest character, and extracts the area in the vicinity of the coordinates 81 from the frame memory 5. cut out

This character image data is sent to the character recognition section 22 and converted into a character code through recognition processing. The control unit 9 controls the transfer of processing. There are already many methods for character recognition, so we will omit them here.

Next, step 104, that is, from the chart data,
A specific method for searching for the instruction word obtained in step 103 will be described.

First, when the instruction word is a figure/table number, there is no need to search if there is data that associates the figure/table number with the location of the data.

When instruction words are embedded in diagrams, the diagram data has characters as codes. There is a first case and a second case where the image only exists as an image.

In the first case, the character code data is selected and the instruction word is searched from therein. Match search section 1 in Figure 1
1 performs this process.

In the second case, image processing is required. An example of this is shown in FIG. In this case, in the character generation section 23,
Although a method is shown in which a character image pattern is generated according to the font and size of the characters used in the diagram, there is also a method in which the pattern of the character part obtained by the character cutting section is used as is. In any case, the character pattern is supplied to the pattern search section 24, and the image data of the chart is searched for a portion that matches the character pattern. In order to reduce the amount of processing, even when the instruction word consists of a plurality of characters, only one character may be searched first, and if a matching portion is found, the next character may be compared with its neighbors.

The choice between the two methods for step 103 and the two cases method for step 104 depends on the type of data provided. The example in Figure 1 corresponds to the case where both are in the form of a code, and the example in Figure 5 corresponds to the case where both are in the form of an image. It is thought that this is often the case, and in this case, they can be configured in combination.

It is necessary to implement the step 110 of creating the instruction word data position relationship table shown in FIG. 4 in advance.

In the case of patent documents, it is necessary to create only figure/table numbers and instruction words using numbers.Even when there are only six image data, it is useful to recognize only the numbers or the alphabet attached to them. Also, for general documents, it is useful to prepare just figures and tables numbers.

The display of the chart in step 105 may be performed as follows. If there is screen space to display the entire diagram, including the instructions, display the entire diagram.

At this time, at least the part near the specified part of the original sentence will remain. If it is not possible to display the entire sentence without leaving the original sentence, you can select to display reduced duplicates or to display only the area containing the part containing the specified word. Bye.

Furthermore, when a reference word is embedded in a diagram, it is easier for the author to find it if the reference word is highlighted (blinking, black and white inversion, j1 degree/color change, etc.).

〔Effect of the invention〕

According to the present invention, by simply specifying a word in a sentence, the corresponding figures and tables can be automatically searched and displayed side by side, without the need for the operator to perform operations such as searching the displayed page or scrolling the position. Therefore, it is possible to provide new functions that were not possible with the conventional method of viewing summarized documents on paper.
Understanding can proceed without interruption of thinking, improving efficiency.
