Abstract

PURPOSE:To generate automatically an index by extracting a key word which is used as the index at every inputting of a character string, and setting an appearance page number in a sorted key word table at the time of storing a document. CONSTITUTION:At the time of inputting the character string by an operator, a key word deciding part 3 retrieves a key word dictionary 2, and simultaneously, if an inputted character string is decided as the key word, it decides whether the key word is a newly appeared key word, by an appearance key word managing part 6, and when it is the newly appeared key word, it is stored in a key word table storage part 5. Next, the inputted character string is stored in a text buffer 4, and after documentation is completed, the key word table in the key word storage part 5 is sorted. A document storage control part 8, after storing the current page number of the key word included in the page in the page number part of the key word table in the key word table storage part 5, stores the page in an external memory device 9, and stores the key word table of the key word table storage part 5 in the external memory device 9.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document processing device such as a Japanese food processor, and more particularly to a document processing device that creates an index of input documents using a keyword dictionary created in advance. Regarding.

BACKGROUND OF THE INVENTION Conventionally, in order to add an index to a created document, after the document has been created and printed, the creator has to pick out the keywords that will become the index and input them again. FIG. 4 shows an index creation procedure in a conventional document processing device.

After a document is created in step 201 and registered in an external storage device, the document is printed in step 202. The creator visually inspects the information, extracts keywords to be used as an index in step 203, and sorts the keywords in reading order. Step 20
The keyword extracted in step 4 and the page number on which it appears are input, and the index is printed in step 205.

Problems to be Solved by the Invention However, with the processing method described above, keywords that serve as an index must be extracted and re-entered after document creation, and page numbers must be checked again when the number of sentences increases or decreases. Creating an index required a great deal of effort.

The present invention has been made in view of the above, and is a document that can automatically create an index and the page number where it appears by extracting a predetermined keyword as an index keyword at the same time as text is input, and storing it together with the text. The purpose is to provide processing equipment.

Means for Solving the Problems The present invention provides a keyword dictionary that is a list of keywords serving as an index, a keyword determination unit that determines whether an input character string matches an already registered keyword, and a keyword determination unit that determines whether an input character string matches an already registered keyword. A keyword table storage unit that registers this as an index element when it is stored in the keyword table, an appearance keyword management unit that determines whether it has already been registered in the keyword table when storing it in the keyword table, and a sorting unit that notes the keyword table in the order of keyword codes. and a text storage control unit that has a text buffer for storing inputted fixed character strings, detects the keyword of each page when saving the text, and sets the page number in the key food table storage unit. With the above-described configuration, the present invention extracts a keyword to serve as an index each time a character string is input, and sets the appearance page number in the keyword table noted when storing a document, thereby creating an index. can be created automatically.

Embodiment FIG. 1 is a diagram showing the configuration of a document processing apparatus in an embodiment of the present invention. In Figure 1, 1 is an input section such as a keyboard, 2 is a keyword dictionary that stores a list of keywords, and 3 is a device that determines whether a character string input from input section 1 exists in keyword dictionary 2. 4 is a text buffer that stores the character string input from the input unit 1; 5 is a keyword table storage unit that stores the keywords determined by the keyword determining unit 3'; 6 is a keyword determining unit 3; 7 is a keyword management unit that checks whether the input character string determined as a keyword is already stored in the keyword table storage unit 5; 7 is a sorting unit that sorts the keyword table in the keyword table storage unit 5 in keyword order; 8 is a sorting unit; 9 is a document storage control unit which controls the storage of each page of text and at the same time stores the page number in the keyword table storage unit 7 when a keyword stored in the keyword table storage unit 7 appears on the stored page; 10.11 is a print control unit and printing unit that prints the contents of the text buffer 4 and the keyword table storage unit 5; 12.13 is used to print the contents of the text buffer 4 and the key food table storage unit 5; These are a display control unit for displaying images and a display unit such as a CRT.

Next, the operation f of the present invention shown in FIG. 1 will be explained using FIG. 2.

In step 401 of FIG. 2, the operator inputs a character string from an input means such as a keyboard. In step 402, the keyword determination unit 3 searches the keyword dictionary 2 while
Determine whether the input string is a keyword. If it is determined as a keyword, step 40
In step 3, the appearing keyword management unit 6 determines whether the keyword has newly appeared, and if it is a newly appearing keyword, it is stored in the keyword table storage unit 5. FIG. 3 shows the data structure of the keyword table stored in the keyword table storage section 5. The character string input in step 405 is stored in the text buffer 4. In step 406, it is determined whether the document creation is finished, and if it is finished, step 407
The keyword table in the keyword table storage section S is sorted. In step 408, the document storage control unit 8 stores the current 100 number in the page number section Q of the keyword table in the keyword table storage unit 5 regarding the keywords included in that page, and then stores the page in the external storage device 90,000. At step 410, it is determined whether all pages of text have been stored, and at step 41
In step 2, the keyword table in the keyword table storage section 5 is stored in the external storage device 9. In step 413, the operator enters the mark: j
When the instruction is issued, the keyword table is printed after printing the document in steps 414 and 415.

Effects of the Invention (According to the present invention, an index can be automatically created at the same time as a document is created, without having to pick out keywords to be used as an index after the text is created.
