Abstract

PURPOSE:To find out an editing point with less screen display even if no hard copy of a document exists, by providing a document display device with a mode for displaying the keyword of each page of the document. CONSTITUTION:Character data inputted from an input part 1 is stored in a document storage part 2. Data on one screen of a specified page is transferred from the storage part 2 to a document screen buffer 4 and dispalyed on a display part 15 through a changeover switch 14. When the switch 14 is set at the side of the keyword mode for connecting a keyword screen buffer 13 to the display part 15, a keyword extracting part 5 reads character data 3 on the specified page successively out of the storage part 2. The extracting part 5 selects a keyword in the read data 3 and writes it in a buffer 13. Said operation is added for succeeding pages until the buffer 13 becomes full state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document creation device that creates and displays documents by inputting kana, kanji, alphabets, φ numbers, and the like.

Conventional Examples and Their Problems Document fV generation devices, typified by word processors, generally have two modes: input and editing. In the edit mode, corrections, insertions, deletions, etc. are made to a part of the document that has already been created, but the user must first specify the editing position. If the desired part is already displayed on the screen, just move the cursor to that part. If the desired part is not displayed on the screen, use the conventional method 1.
Most of the information was displayed in the following way.

The first method is possible for iM when an eight-dimensional copy of the document exists in one. That is, the user looks at the hard copy, determines how many lines the desired portion is located, and inputs the position information into the document creation device to display the document. This method has problems in that the user's eyes and hands are temporarily removed from the document creation device, resulting in a decrease in work efficiency, and in that a hard copy is required.

The second method is a method that can be used repeatedly even without a hard copy. When the page number, U-th, or approximate page number of a document is known, the page is sequentially displayed on the screen from that page and checked to see if the desired part is included. This method has the disadvantage that in the case of a document with a large number of pages, the amount of information displayed on the screen is too small, tiring the user's eyes.

OBJECT OF THE INVENTION The present invention solves the drawbacks of the prior art, and by providing a document display device with a mode for directly displaying the keywords of each member of the document, even when there is no hard copy of the document, it is possible to display it on a smaller screen. The purpose is to make it possible to find the editing position.

Structure of the Invention In order to achieve the above object, the document creation device of the present invention includes an input section for inputting character data consisting of kana, kanji, alphabets, numbers, etc., and an intersection storage section for storing character data from the input section. and 871: 11' protruded from the document storage section.
l! a document screen buffer that holds character data for 11 pages; a keyword extraction unit that extracts keywords from the 11J document storage unit; a keyword screen buffer that holds one screen worth of keywords output by the +SiJ giewaki extraction unit; It is possible to provide a display section having a normal mode for displaying the contents of document screen variations and a keyword mode for displaying the contents of the keyword buffer, and to search for a position by looking at the display on the display section in the keyword mode. be.

DESCRIPTION OF EMBODIMENTS Hereinafter, an example of the hitch 7j (fh) of the present invention will be explained based on FIGS. 1 and 2.

In Figure 1, (1) is an input section for character data consisting of 11 kana, kanji, alphabets, numbers, etc., (2) is a document storage section that stores character data from input section (1), and (4) is a character data input section. A document screen buffer that reads data (3) for one screen from the 6iJ document storage section (2) and holds it; (5) is a keyword extraction section that extracts keywords from the document storage section (2); ), Katakana judgment section (7), Alphabet judgment section (8), Number judgment section (9), Keyword length judgment section (1
0, frequency determination unit (II), keyword number determination unit (12
). (13) is a keyword screen buffer that holds one screen worth of keywords output by the keyword extraction section (5); The content of 13) is selectively input, and the input content is displayed on the screen.Hikoo, the above keywords are words and phrases that have important meanings in the sentence. Size, one outside the alphabetical notation Nii-kun,
In addition to satisfying the basic conditions such as words with numbers added to the above, it is also necessary to satisfy at least one of the following conditions: O length is more than a certain value, and 0 frequency in the document is more than a certain value. be.

Character data input from the input section J (1) is stored in the document storage section (2) in page size units. In normal mode, the OFF 1st column switch (14) is the document screen buffer (4
) and the display section (15) are connected. Document screen buffer (
4) During both input and editing, one screen worth of character data for the designated page is transferred from the document storage section (2), so they are displayed on the screen in the normal mode. In the keyword mode in which the changeover switch Q(1) connects the keyword screen buffer (13) and the display section θ5), the keyword extraction section (5) operates as follows 7f.

First, the character data (3) of a designated page is read out from the sentence latent memory section (2) in order from the beginning to the end of the page.

The kanji determination unit (6), katakana determination unit (7), alphabetic character determination unit (8), and numeric determination unit (9) detect those consisting only of kanji, katakana, alphabetic characters, and numeric characters from among the read character strings. . The keyword length determination unit 00 determines whether the length of the detected character string is greater than or equal to a certain value (for example, 4). The frequency determination unit (11) determines whether a character string appears a certain number of times or more within the same page or adjacent pages (for example).

3) Determine whether or not it has been detected. As described above, the keyword extraction unit (5) is configured so that a keyword is recognized as a keyword if at least one of the above two types of determinations is satisfied. Note that the keyword number constant section α2 exists to prevent the number of keywords within the same page from becoming extremely large due to the nature of the document. That is, if the number of keywords within the same page exceeds a certain value (for example, 10), a certain number of keywords with the highest frequency are selected. In this way, only the keywords that ultimately remain are written to the keyword screen buffer (131).The above operations are applied to successive pages until the keyword screen buffer (131) is full.

FIG. 2(a) (tj is an example of a screen when the same page is displayed in normal mode and keyword mode, respectively.

As described in the detailed description of the invention, according to the present invention, only keywords that are important words for each member of a document can be displayed, so unlike the conventional method, when editing a document, there is no need for humans to read the hard copy or for each member. It used to be a tedious job to display all the contents on the screen...It is now possible to specify Shuiura with a much smaller amount of work, and the amount of screen display can be reduced more than humanly possible. It can reduce eye fatigue.
