Abstract

PURPOSE:To automatically extract a candidate keyword from documents and to facilitate giving a keyword by giving the applicable knowledge of keywords to a documentation device instead of a documentator even though the documentator do not have a general keyword knowledge. CONSTITUTION:When documentation is decided to end, whether or not the keyword is given to the just generated document is decided. If a keyword is given, a keyword selection control part 12 is activated, and contents in an appearing keyword table 7 are displayed on a display device 9. A keyword display part 13 sequentially displays keywords from the appearing keyword table 7 in the high frequency order of candidate keywords. The documentator selects a target keyword out of the displayed keyword group with the aid of an input device 1. Upon the completion of keyword selection, a document stor age part 10 and a keyword storage part 14 are activated to register the documents provided with keywords in a memory device 11. On the other hand, documents instructing that giving a keyword is unnecessary are registered in the memory device 11 by activating only the document storage part 10.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a Japanese document creation device, and particularly relates to assigning keywords for searching to created documents, and performs kana-kanji conversion in advance at the time of document creation. It relates to a process of automatically extracting keyword candidates from time to time, and later selecting a desired keyword from the candidate keywords.

(Prior Art) Conventionally, keywords can be assigned to a created document by the creator inputting predetermined keywords after the document is created.

FIG. 2 shows a keyword assignment procedure in a conventional document creation device. A document is created in step 21, and when one creation is completed, the document is registered in step 22. In step 23, the creator determines whether it is necessary to add keywords,
If necessary, a keyword is manually entered in step 24 and registered as a keyword for this document in step 25.

If keywording is not necessary, the process ends in step 23.

(Problem to be solved by the invention) However, the processing procedure described in Section 2 requires time and effort to reconsider and input keywords after document creation, and also requires knowledge of keywords (for example, patent classification and document search). be done. This is because, although it is fine if the document creator only uses keywords for personal classification, when other people try to search for the document, the keywords need to have a certain degree of versatility.

In view of this, the present invention provides that even if a document creator does not have general knowledge of keywords, the document creation device itself has knowledge of keywords, automatically extracts candidate keywords from a text, and easily assigns keywords. The purpose is to provide a document creation device that can

(Means for Solving Problems) The present invention includes a kana-kanji conversion dictionary in which keyword flags are attached to words serving as keywords, and means for determining whether a word determined after kana-kanji conversion can be a keyword, and candidate keywords. If so, means for storing the candidate keywords in the appearance keyword table each time, and means for indicating to the operator the candidate keywords stored in the appearance keyword table together with the frequency of appearance.
This document creation device includes means for selecting a target keyword from displayed candidate keywords, and means for storing the keyword together with a created document.

(Function) With the above-described configuration, the present invention corresponds to a predetermined keyword each time Kana-Kanji conversion is performed.

When a word is determined, this word is stored as a keyword in the appearance keyword table. In the appearance keyword table, when a candidate keyword is raised as a candidate, it is sequentially stored in the table, and if the keyword is already stored, the frequency of appearance is updated. When the document creation is completed, if a keyword needs to be added, candidate keywords in the appearance keyword table are shown to the creator, and the creator selects the desired keyword. In this way, a document creator can add appropriate keywords to a document without having special knowledge of keywords.

(Embodiment) FIG. 1 shows a configuration diagram of a document creation device in an embodiment of the present invention. Reference numeral 1 denotes an input device, which includes character keys for inputting characters, symbols, etc. for creating a document, and editing keys used when editing a document. 2 is an input control unit, an input bag! i! Analyze the input key information input from 1. Reference numeral 3 denotes a kana-kanji conversion section, and if the input key information is a character code, the information is sent here from the input control section 2, and the information is converted into a sentence mixed with kanji or a foreign word. 4 is a conversion dictionary with a keyword flag, which is used by the kana-kanji conversion unit 3 to convert a hiragana code string into a kanji code. This dictionary also has a built-in keyword flag that indicates whether the converted word is a keyword. 5 is a keyword determination section.

It is determined whether the word resulting from the kana-kanji conversion is a keyword candidate. 6 is a document memory section, which consists of sentences mixed with kanji that have been converted into kana and kanji.

This is the part that is stored in memory as one document.

Reference numeral 7 denotes an appearance keyword table, which stores keyword groups determined by the keyword determination unit 5 to be keyword candidates. Reference numeral 8 denotes a document display section, which controls the display of the contents of the document memory section 6 that are being created. A display device 9 displays the contents of the document memory section 6 controlled by the one-document display section 8 on the display device. Reference numeral 10 denotes a document storage unit, in which the contents of the six created document memories are stored in a storage bag h! Controls storage in ill. 12 is a keyword selection control unit, which displays candidate keywords stored in the appearing keyword table 7 on the display device 9 after completion of document creation, and allows the document creator to select a desired keyword from the displayed keyword group. . Reference numeral 13 denotes a keyword display section, which performs processing such as arranging the candidate keywords stored in the appearance keyword table 7 in order of frequency of occurrence so that the document creator can easily select them, and displays the results on the display device 9. It is. 1
Reference numeral 4 denotes a keyword storage unit, which stores keywords selected by the document creator in the storage device 11 together with the created document.

Next, the operation of the present invention shown in FIG. 1 will be explained using FIG. 3.

In FIG. 3, step 31 is a character input stage, in which input key information input from the input device 1 is passed to the input control section 2. In step 32, kana-kanji conversion is performed using the input key information. At this time, the conversion dictionary 4 with keyword flags is used. Homophones are selected in step 34 until they match the target kanji (or foreign words, etc.), and once the conversion result is finalized, if the word can be a keyword (i.e. it is converted with a keyword flag) If a keyword flag is attached to the converted word in dictionary 4), the keyword flag is turned on for that word and the word is passed to the next step.

This flag is turned off when it cannot be a keyword.

FIG. 4 shows the contents of the conversion dictionary 4 with keyword flags.

In step 35, it is determined whether the converted word string is a keyword candidate. If the keyword flag is on, this word is stored in the appearance keyword table 7 as a candidate keyword in step 36. In step 361, it is determined whether this keyword has already been stored as a candidate keyword, and if it is a new keyword, it is stored in the appearance keyword table 7 as a new candidate keyword in step 362.

If the keyword is already stored, step 36
In step 3, add 1 to the frequency of appearance of the corresponding candidate keyword. Fifth
The figure shows the structure of the appearing keyword table.

After storing the candidate keywords in the appearance keyword table 7, word examples are stored in the document memory section 6 in step 37. The word group whose keyword flag is determined to be off in step 35 is directly stored in the document memory section 6 in step 37. In step 38, it is determined whether the creation of this document has been completed, and if it has not been completed, the process returns to step 31. If the document creation is completed, it is determined in step 39 whether a keyword should be added to the document just created (at this time, a message indicating whether or not a keyword should be added is displayed on the display device 9, and an instruction from the document creator is awaited). When assigning a keyword, the keyword selection control unit 12 is activated in step 310 to display the contents of the appearing keyword table 7 on the display device 9. During this display, the keyword display section 13 displays candidate keywords in order of appearance frequency from the appearance keyword table 7. In step 311, the document creator uses the input device 1 to select a desired keyword from the displayed candidate keyword group. When the keyword selection is completed, in step 312, the document storage unit 10. The keyword storage unit 14 is activated and the document to which the keyword has been added is registered in the storage device 11. On the other hand, if the document creator instructs in step 39 that keyword assignment is unnecessary, in step 312 only the document storage section 10 is activated and the document to which no keyword has been assigned is registered in the storage device 11. As described above, according to this embodiment, keywords can be easily assigned to documents by automatically selecting keywords by the device itself, even if the document creator does not have special knowledge about keywords when creating a document. can be realized.

(Effect of the invention) 1 - As explained, according to the present invention.

(1) Even if the document creator has no knowledge of keyword assignment, general-purpose keywords can be assigned to the document.

(2) Since the device automatically selects keywords, the document creator does not need to perform extra consideration or operations to create keywords.

(3) The assigned keywords are general-purpose and have high utility value when other people use this keyboard to search for documents, and their practical effects are great.
