Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus such as a Japanese word processor or a computer capable of creating a document in Japanese, and particularly, it is possible to retrieve a desired character string from an input document. The present invention relates to a document processing device having a simple character string search function.

[0002]

2. Description of the Related Art Although application software used in many document processing apparatuses is equipped with a character string search function, ordinary applications only include a character string as specified. Many are not searched. However, recently, not only searches that do not distinguish between uppercase and lowercase letters, but also searches that do not distinguish between full-width and half-width alphanumeric characters and katakana, or UNIX regular expressions have appeared.

[0003]

However, when actually using application software that handles Japanese, those character string search functions are not sufficient. As an example, in the past, the search term “interface” cannot search for the terms “interface” and “interface”. In this way, "words with fluctuation notation" (words with fluctuation notation mean, like "interface" and "interface" above, for one word, multiple types of expressions with the same reading and the same meaning. , Etc.), “used phrases”, “phrases written in different glyphs”, etc., can be searched for in Japanese documents that have a wide range of notations. Although it is more convenient and practical in several steps, it has not been realized in the conventional document processing device.

The present invention has been made in consideration of such circumstances, and in the search of character strings, "words with fluctuation notation" and "words used", which are characteristic of Japanese,
Alternatively, the invention provides a document processing device capable of searching for “words written in different characters” and the like.

FIG. 1 is a block diagram showing the configuration of the present invention. As shown in the figure, the present invention is
A large number of words and phrases including kanji are stored together with their reading information, and for each word, a dictionary means 101 that stores in advance words and phrases that have the same phonetic synonyms and different notations, storage means 102 that stores various documents, and search. When a word to be searched is input from the input means 103 for inputting a word to be searched, a word having the same word as the word to be searched and a word having the same synonym and different notation from the word are read from the dictionary means 101. Read-out means 104 for outputting and storage means 1
No. 02 stored in the document No. 02, the retrieval unit 105 for retrieving the term read by the reading unit 104, and the display unit 106 for displaying the retrieval result by the retrieval unit 105
And a document processing device.

[0006]

According to the present invention, when the word to be searched is input from the input means 103, the reading means 104 makes a dictionary the same as the word to be searched and the word having the same synonym and different notation from the word. The document read by the means 101 and retrieved by the retrieval means 105 is searched for the word / phrase read by the reading means 104, and the result is displayed on the display means 106.

Therefore, when searching for a word, not only the same word as the word to be searched but also words having the same phonetic synonyms and different notations can be searched. It is possible to eliminate the inconvenience of searching due to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the embodiments shown in the drawings. The present invention is not limited to this. FIG. 2 is a configuration block diagram of an embodiment in which the present invention is applied to a Japanese word processor. The document processing device of the present invention includes a CPU 1, an internal storage device 2 including a ROM, a display device 3 including a CRT display device or an LC (liquid crystal) display device, an input device 4 including a keyboard, and a floppy disk device or a magnetic disk device. It is composed of an external storage device 5 including the above.

The internal storage device 2 stores a search program including the functions of the present invention. The external storage device 5 includes a basic dictionary 6 in which a large number of words and phrases including Chinese characters are stored in advance together with reading information, and a fluctuation notation dictionary 7 in which words having the same synonyms and different expressions are stored in advance for each word. It is stored. Also, a database 8 of documents to be searched is stored.

Various character strings are input from the input device 4, and a word or phrase to be searched is input when the character string is searched.

When the word to be searched is input from the input device 4, the CPU 1 searches the basic dictionary 6 for the same word as the word to be searched, and when the word is searched, the CPU 1 next sounds the same as the word. Words having the same meaning but different expressions are retrieved from the fluctuation notation dictionary 7 and read. Then, the read phrase is
Search from documents stored as database 8,
The search result is displayed on the screen of the display device 3.

In this apparatus having such a structure, it is assumed that the external storage device 5 has a database 8 (document or the like) to be searched, which is stored in the internal storage device 2 by a search program including the functions of the present invention. When searching, the search program prompts the user (searcher) to specify the phrase to be searched on the display device 3, and the user inputs the phrase to be searched from the input device 4. When the search term is specified, the search program is stored in the external storage device 5.
Referring to the basic dictionary 6 and the fluctuation notation dictionary 7 placed in
A search is performed to see if the target word / phrase exists in the database 8 to be searched. Regarding the search result, a message indicating the success or failure is displayed on the display device 3 to inform the user.

FIG. 3 illustrates an example of the structure and function of the search program of the present invention when the database 8 is searched. The search program mainly includes a search routine 11, a document access routine 12, a basic dictionary 6, a fluctuation notation dictionary 7, a search word designation routine 13, and a search result display routine 14. Search term specification routine 1
When a word to be searched for is specified through the input device 4 through 3, the search word is passed to the search routine 11. Through the document access routine 12, the search routine 11 executes pattern matching by referring to the basic dictionary 6 and the fluctuation notation dictionary 7 as to whether the search target database 8 contains a search word. The search result is displayed on the display device 3 by the search result display routine 14.

Next, the basic dictionary 6 and the fluctuation notation dictionary 7 referred to by the search routine 11 will be described. The basic dictionary 6 is a Japanese dictionary used in a Japanese language processing system such as ordinary Japanese word processing software, to which information about fluctuation notation is added. Regarding the regular fluctuation notation such as in the case where the sending kana is different, the information is written in the basic dictionary 6.

FIG. 4 shows an example of the structure of the data part of the basic dictionary 6. In FIG. 4, reference numeral 21 is “reading”. For example, in the case of the phrase “writing”, “write”
That is the reading information. Reference numeral 22 is a Japanese phrase (standard notation) containing a mixture of kanji and kana, which is the notation "write" if "write" in the above example.
Reference numeral 23 is information such as part of speech, and 24 is utilization information.

Reference numeral 25 is fluctuation notation rule information when there is a regular fluctuation notation, and information indicating that there are rules of notation patterns of "write" and "write" for "write" in the above example. Is. Reference numeral 26 is a flag indicating that the irregular fluctuation notation that cannot be recorded in the basic dictionary 6 is stored in the fluctuation notation dictionary 7. When this flag is turned on, the notation pattern is written in the fluctuation notation dictionary 7. As shown. 27 is information for learning.

The fluctuation notation dictionary 7 is a collection of irregular fluctuation notations that could not be recorded in the basic dictionary 6.
If no match is found as a result of the reference of the basic dictionary 6, it is subsequently referred to.

FIG. 5 shows an example of the structure of the data part of the fluctuation notation dictionary 7. In FIG. 5, reference numeral 31 is a management code that represents the start position of the fluctuation notation of a group and includes dictionary management information such as the number of notation patterns and the length of each notation pattern. 32, 33, 34 ... are concrete notation patterns. For example, in the case of the phrase “interface”, the notation 1 is recorded as “interface”, the notation 2 as “interface”, and the notation 3 as “interface”. Keep it. The basic dictionary 6 and the fluctuation notation dictionary 7 have a structure that can be changed / added / deleted on the user side by a utility program.

FIG. 6 is a flow chart showing an example of the operation of the search routine 11 of the present invention. Search routine 11
Fixes the search range of the document to be searched according to the user's instruction (step 41), cuts it out at the word / phrase level with reference to the basic dictionary 6 (step 42), and the search specified as the cut-out phrase. Compare with words (step 43). Here, if there is a match (step 44), the result of successful search is displayed (step 48), and the process ends.

In step 44, if the search using the basic dictionary 6 is not successful, the search routine 11 refers to the fluctuation notation dictionary 7 (step 45) and executes comparison with the search word (step 46). ). Here, if there is a match (step 47), the result of successful search is displayed (step 48), and the process ends. If they do not match, if the search is continued (step 49), the next word / phrase is searched (step 50). If there is no match in step 47 and the search is not continued in step 49, the result of unsuccessful search is displayed (step 51), and the process ends.

In this manner, by searching for the same phrase as the phrase to be searched and the phrase having the same synonym and different notation as the phrase, a Japanese document having a wide range of notations can be used. You can search for phrases such as "phrases,""usefulphrases," or "phrases written in variants." For example, if "write" is specified, "write" as well as "write" can be searched. Alternatively, if "interface" is specified, not only "interface" but also "interface" and "interface" can be searched. If you specify "Kanazawa," you can search for "Kanazawa" as well as "Kanazawa." Therefore, according to the present invention, it is possible to specify a search term in a Japanese document search without worrying about inconsistency in Japanese notation.

[0022]

According to the present invention, in searching for a word, not only the same word as the word to be searched but also all the words having the same synonyms and different notations are used. In search of, you can specify search terms without worrying about inconsistency in Japanese notation,
As a result, the hit rate of the search can be improved and the time and effort required for the search can be shortened. Also in connection with
The effect of improving the database creation efficiency is derived because you do not have to worry about the Japanese notation when entering Japanese documents that are the database to be searched or when creating an index for search. .. Further, a synonym search can be easily realized.
