Description

[Detailed Description of the Invention] <Technical Field> The present invention is applicable to Japanese word processors that input kana characters from a kana keyboard according to the pronunciation of the characters and output kanji or sentences containing kanji and kana. The present invention relates to a conversion processing device.

<Prior art> In conventional kana-kanji conversion processing devices, meaningless kanji or kana are converted into kana-kanji when converting compound words that are separated into two separate words depending on how they are separated in a specific kana character string. Candidates for combinations of character strings containing kanji are created. For example, if you want to find the kana-kanji character string ``Itadakimasta'' (verb ``Itadakimashita'') + auxiliary verb (Kana-kanji), the combination ``Top ・Mashita'' (Noun + Noun) will be created. Put it away. Also, in the kana character string "Shinkai Hatsu", the prefix "new/development" + noun is the desired word, but "evolution/remaining hair" is the desired word.
You can use the noun + noun combination ``deep sea/origin'' or the noun + suffix combination ``deep sea/origin''.

Conventionally, in order to avoid the generation of meaningless combination candidates, attempts were made to solve the problem by processing the meaning of each word, but this would require a large capacity for the dictionary and processing program, making it impossible to implement with an inexpensive system. It was hot.

<Object of the invention> The present invention has been made in view of the above circumstances, and by registering information on words that are meaningless combinations in advance, it is possible to eliminate meaningless combinations without increasing the program capacity or the dictionary capacity. It is an object of the present invention to provide a kana-kanji conversion processing device that does not generate candidates for character strings that are compound words.

<Structure of the Invention> In order to achieve the above object, the present invention has a kana-kanji conversion dictionary that stores in advance kanji corresponding to kana character strings or character strings containing kana-kanji mixtures. In a kana-kanji conversion processing device that converts a character string into a kanji or a kana-kanji mixed character string by referring to the kana-kanji conversion dictionary, the kana character string of each word stored in the kana-kanji conversion dictionary and its Each word is associated with the information content of a kanji or kana-kanji mixed character string, and if these words are followed, it makes sense as a whole kana character string, but each converted kanji or kana-kanji mixed character string is The present invention is characterized in that it is equipped with a dictionary that stores compound prohibition information for words that are meaningless combinations as compound words.

<Example> An embodiment of the present invention will be described below.

FIG. 1 shows the configuration of a kana-kanji conversion processing device. The input unit 1 includes a group of kana keys for 50 syllabary characters, a conversion key for instructing kanji conversion, and the like. CPU
2 sends information on the kana character string input from the input unit 1 to the kana-kanji conversion unit 3 according to a predetermined processing program. The kana-kanji conversion unit 3 searches the kana-kanji conversion dictionary 4 and meaningless dictionary 5 for the input kana character string, and converts the information of the kana character string into information of a kanji or a character string containing kana-kanji. and sends it to CPU2. Then, the CPU 2 sends information on the character string containing kanji or kana-kanji to the display unit 6 according to the processing program, and the display unit 6 displays the information on the kanji or kana-kanji mixed character string for the kana character string input to the input unit 1. Display the string.

The contents of the Kana-Kanji conversion dictionary 4 are as shown in Figure 2, columns a, numbers assigned to each word,
It consists of column b for the kana character string of the word, column c for the character string containing kanji or kana-kanji, and column d for the part of speech of the word.

The meaningless dictionary 5 stores information on words that become meaningless combinations when a kana character string is converted into a kanji character string or a character string containing kanji characters. As shown in Fig. 3, the contents of this meaningless dictionary 5 are as follows: column f with the same number as column a of the kana-kanji conversion dictionary 4 assigned to each word; is a candidate for kana-kanji conversion as a compound word, but it does not make sense when combined as a converted kanji or a character string containing kana-kanji, so it is set to ``1'' or ``0'' depending on the presence or absence of pre-registered words. '', and when there is a word that does not make sense when combined because the information in column g is ``1'' indicating compound prohibition information, it is assigned in the Kana-Kanji Conversion Dictionary 4 for that word. It consists of a column h in which a number is registered in advance.

Then, in the kana-kanji conversion section 3, the input means 1
When converting an input kana character string into a kanji character string or a character string containing kana-kanji characters, this meaningless dictionary 5 is searched together with the kana-kanji conversion dictionary 4, and the kana-kanji conversion dictionary for the input kana character string is searched. 4, the number in column f is searched from the number in column a, and the information in column g for this number in column f is determined. If the information in column g is "1", there are words that make no sense when combined, so enter the number of this word in column h.
Search. Then, for the input kana character string, the word in the kana-kanji conversion dictionary 4 corresponding to the number shown in this column h is not selected as a candidate for kana-kanji conversion.

In this example, in the kana-kanji conversion dictionary 4, the kanji character string number 301 "mashita" does not follow the kana character string "itadaki" and the kanji "top" numbered 101, so the meaningless dictionary 5 has the following characters: For number 101 in column f, "1" is registered in column g, and "301" is registered in column h. Also, in Kana-Kanji Conversion Dictionary 4, the number
201 Kana character strings “Shinka”, Kanji character strings “Evolution”
Since the kanji character string ``Imami'' with number 110 does not follow, in meaningless dictionary 5, for number 201 in column f, ``1'' is registered in column g, and ``110'' is registered in column h. Ru. Similarly, in the kana-kanji conversion dictionary 4, the kanji string ``Shinkai'' with the number 202 and the kanji string ``deep sea'' with the number 250 do not follow, so the meaningless dictionary 5 , the number in column f
For 202, "1" is registered in column g and "250" is registered in column h.

Since kana character strings such as ``Shinkamasa'' are not normally input, there is no need to register ``301'' as the number for words that do not follow ``Shinka''. In a meaningful kana character string, only words that become meaningless candidates for kana-kanji conversion due to abnormal delimiting methods are registered.

In the second embodiment of the present invention, as shown in FIG. 4, a meaningless dictionary is added to the kana-kanji conversion dictionary; in this case, the meaningless dictionary 5 in the embodiment shown in FIG. 1 is unnecessary. becomes. In this kana-kanji conversion dictionary 4', the contents of columns a, b, c, and d are the same as those of the kana-kanji conversion dictionary 4 in FIG.
In column a, the number of a word that is a candidate for kana-kanji conversion as a compound word as a kana character string, but has no meaning if it is continued as a converted kanji or character string containing kana-kanji is registered.

When converting a kana character string into a kanji character string or a character string containing kana-kanji characters in the kana-kanji conversion section 3, columns a, b, c,
d, and if there is a number of a word that does not follow in column e, search for that number in columns a,
b and c are searched and the words are not selected as candidates for kana-kanji conversion.

In this case, since it can be created by adding a meaningless dictionary to the existing kana-kanji conversion dictionary, fewer modifications and changes to the processing program are required.

<Effects of the Invention> As explained above, in the present invention, a kana-kanji conversion dictionary is used to collect information on words that would become meaningless combinations when a kana character string is converted into a kanji character string or a character string containing kana-kanji characters. Since the kana-kanji conversion process is performed based on the dictionary stored in correspondence, there is no need to increase the capacity of the kana-kanji conversion dictionary and processing program, and therefore, even in an inexpensive system, meaningless character strings can be avoided. It is possible to eliminate the occurrence of combinations. Furthermore, this can be achieved by adding meaningless information to the existing kana-kanji conversion dictionary, which has the great advantage of requiring fewer modifications and changes to the program.
