Abstract

PURPOSE:To enable selecting reading appropriate for a character string to be converted by a device for converting a 'KANJI (Chinese character) into KANA (Japanese syllabary). CONSTITUTION:A character string to be converted which is inputted from an input device 1 is retrieved by a dictionary main body part from a position obtained by a dictionary index retrieving means 2. The reading of words and their parts of speech are registered in a KANJI/KANA conversion dictionary 3 and when a specific part of speech is specified by a reading selecting means 5, the reading appropriate for the character string can be selected from plural reading states. A display device 6 displays the selected reading.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for processing Japanese, such as a Japanese word processor, by adding a function for converting kanji into kana so that the range of its use can be expanded. It is a device.

[0002]

2. Description of the Related Art A conventional kanji-kana conversion device cannot efficiently select a specific reading from a plurality of readings.

[0003]

In the conventional kanji / kana conversion device, when selecting a desired reading from a plurality of readings registered in one word, the user of the device sequentially looks at the plurality of readings. I had to go through and make a selection, which was inefficient. It is an object of the present invention to provide a kanji-kana conversion device that enables efficient selection of a reading suitable for a conversion target character string by using the part-of-speech information registered for each of the plurality of readings.

[0004]

A kanji-kana conversion device of the present invention comprises a main body part in which words such as kanji, idioms or symbols are stored in association with their phonetic readings and part-of-speech information, and an index part thereof. Based on the search start position obtained by the dictionary index search means for obtaining the search start position by comparing the written information of the input word and the index of the index part A dictionary body searching unit that searches the dictionary body unit and obtains and outputs Yomiana and part-of-speech information, and a selection that selects a reading corresponding to a specific part-of-speech based on the Yomiana and part-of-speech information obtained by the dictionary body searching unit And means.

[0005]

According to the present invention, with the above configuration, the reading and the part of speech corresponding to the character string input by one input device can be obtained. When there are plural readings, by specifying the part of speech, it is possible to select a specific reading that includes the part of speech.

FIG. 1 is a functional block diagram showing an embodiment of the present invention. In the figure, 1 is an input means for inputting a conversion target character string, 2 is a dictionary index search means for obtaining a search start position by comparing the written information of the input word and the index of the index part, and 3 is a kanji or idiom. Alternatively, a kana-kana conversion dictionary composed of a main body storing a word such as a symbol in association with its phonetic reading and part-of-speech information and an index storing the index thereof, 4
Is a dictionary body searching means for searching the dictionary body based on the search start position obtained by the dictionary index searching means 2, 5 is a reading selecting means for selecting a specific reading, and 6 is selected by the reading selecting means 5. It is a display means for displaying the reading and the part of speech.

FIG. 2 is a block diagram of a specific example for realizing the kanji-kana conversion device shown in FIG. Currently, the word notation is shift JIS, EUC, new JIS, old JIS
Various methods such as S can be used, but here Shift JIS
An example using is shown. In the figure, 11 is an input unit (input device) for inputting a conversion target character string. Reference numeral 12 denotes a CPU which searches the conversion dictionary body and transfers data. Reference numeral 13 is a dictionary search table (index portion), and 14 is a kanji-kana conversion dictionary memory (main body portion) in which words such as kanji, idioms or symbols are stored in association with their phonetic readings and part-of-speech information. The dictionary search table 13 includes notation information of the first two characters of the word registered at the beginning of each sector of the kanji-kana conversion dictionary memory 13, and compares the first two characters of the conversion target character string with the search start position. Obtainable. The memory 15 stores a program for operating the CPU 12, the memory 16 stores a total reading obtained as a result of conversion and a part of speech, and the memory 17 stores a final reading based on the total reading stored in the memory 16. This is a memory that stores the reading selected for. Reference numeral 18 denotes a display unit that displays the processing result of the CPU 12.

FIG. 3 is a diagram showing a configuration example of the dictionary search table 13. In the figure, "A", "Asako", "Ishinjo", and "newspaper reporter" are the words registered at the beginning of each sector, and "A", "Asa", "Ichinoku", and "newspaper" are respectively Is the first two letters of the word. At the start of the search, the search start position can be obtained by comparing the first two characters of the conversion target character string with this table.

FIG. 4 shows an example of the structure of the kanji-kana conversion dictionary memory 14 in which the reading and the part of speech of each word are stored. One record is composed of a record length, word notation information, an internal reading code, and a part-of-speech code. When there are a plurality of readings, the reading and the part-of-speech are successively stored. The record length represents the length of the record in bytes, and the word notation is shift JIS code. The internal reading code corresponds to the hiragana corresponding to a unique 1-byte code, and can significantly reduce the capacity of the entire dictionary. Similarly, the part-of-speech code is a part-of-speech assigned to a unique 1-byte code.

FIG. 5 is a flowchart showing the operation of the CPU until a character string is input from the input unit 11 and the reading of the converted character string is output to the display unit 18. Input unit 11
When a character string is input, the Kanji pointer is at the beginning of the character string. At D1, 1 from the Kanji pointer at the start
A character string of characters is acquired as a character string to be converted, and in D3, the search is started from the search start position obtained by the dictionary index search means 2 in D2, and if the search is possible, the longest match method is used. If the search cannot be performed, the conversion target character string is lengthened by one character and the search is performed again.
At D4, the end of the conversion target character string is compared with the end of the original character string, and if they match, the Kanji pointer is moved to the next character and the process is repeated from D1. At D7, the full reading and part-of-speech of the conversion character string are transferred to the full-reading part-of-speech storage memory 16, and if there are plural readings, the part of speech of the conversion character string is input from the input unit 11 to select the reading including the part of speech. To be done. At that time, it is possible to automatically select the part of speech by designating the part of speech in advance. If the specified part-of-speech is included in multiple readings, the previously registered reading is automatically selected. At D10, the selected reading is linked and stored in the read output result storage memory 17. At D11, if the Kanji pointer reaches the end of the original character string, the contents of the read output result storage memory 17 are displayed. If not, the converted character string length,
The kanji pointer is moved to the next position, and the process is repeated from D1.

[0011]

As described above in detail, according to the present invention, it is possible to easily convert from kanji to kana, and when selecting a reading from a plurality of readings, a reading suitable for the conversion target character string is selected. can do.
