Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a language processing device that aims to reduce dictionary capacity.

[Technical background of the invention and its problems]

In recent years, various language processing devices using information processing technology, such as Japanese word processors and automatic translation devices, have become widespread.

Dictionaries built into this type of language processing device generally store the notation of a word and key information for searching the word in correspondence with each other, and search for the notation of the word according to this key information. It's summery. For example, in a Japanese word processor, a word dictionary is prepared for kana-kanji conversion processing, and the kanji headword is searched using the kana headword as a search key.

By the way, each of the above kanji information is expressed as 2-byte information as specified by JIS. Also, many words are expressed as combinations of multiple kanji. For this reason, when constructing a word dictionary for the Japanese word processor, a large capacity storage device is required, which poses a major problem in reducing its size.

[Purpose of the invention]

The present invention has been made in consideration of these circumstances, and its purpose is to provide a language processing device that reduces the dictionary capacity and can easily be miniaturized.

[Summary of the invention]

The present invention has an input section for inputting key information such as a kana character string, kanji information representing individual kanji, and idiom information representing an idiom composed of multiple kanji, each stored as a headword at a predetermined address. and a conversion unit that searches the conversion dictionary using the key information input from the input unit as a reading and converts the kana character string into kanji information or compound word information, the conversion dictionary The idiom information stored in the idiom information is expressed by address information regarding an address where kanji information of a plurality of kanji constituting the idiom information is stored, and delimiter information indicating the division of pronunciations of the idiom information. shall be.

〔Effect of the invention〕

According to the present invention, the phrase information stored in the conversion dictionary is expressed by the address information regarding the address where the kanji information of the plurality of kanji constituting the phrase information is stored, and the reading delimiter information of the phrase information. Therefore, the amount of information can be reduced compared to the case where the compound word information is simply stored as a combination of the plurality of kanji information that makes up the compound word information.

Specifically, for example, kanji information for one kanji character is
In the case of JIS code, it is 2 bytes, so kanji 2
When expressions consisting of letters are expressed in JIS code,
It requires 4 bytes of data, but if this is expressed as the address information of the address where the JIS code of 2 kanji characters is stored and the delimiter information indicating the division of readings as in the present invention, for example, about 2 bytes. It can be expressed using the following data.

In general, many of the words used in Japanese sentences are compound words made up of combinations of multiple kanji, so by configuring a conversion dictionary like the present invention, the amount of information can be reduced when looking at the word as a whole. Since it is possible to significantly reduce the size of the conversion dictionary and reduce the capacity of the conversion dictionary accordingly, it greatly contributes to downsizing of the language processing device.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of the main parts of the embodiment device,
1 is an input section for search key information; 2 is a conversion section that searches the conversion dictionary 3 according to the search key information to find a headword corresponding to the search key information; 4 is a headword searched by the conversion section 2; This is an output section that outputs .

When this language processing device is implemented as a Japanese word processor, the search key information given to the input unit 1 is, for example, a kana character string input from a kana keyboard, and the conversion dictionary 3 It is realized as a word dictionary that stores words written in Kanji characters as reading information in columns.
Then, the conversion unit 2 converts this word dictionary (conversion dictionary 3)
is used to perform kana-kanji conversion processing on the input kana character string and output it.

FIG. 2 shows an example of the configuration of a conversion dictionary in such a language processing device. The key information from the input unit 1, that is, the idiom character string is used as a reading, and the kanji character corresponding to this reading (kana character string) is (string)
is stored as a kanji headword. still,
This conversion dictionary 3 also stores attribute information such as part-of-speech information for the headwords and delimiter information for the headwords of compound words, which will be described later.

However, in this conversion dictionary 3, a kana character string to obtain a one-character kanji entry word, for example, ``Aka'' is used.
The kanji headwords for the kana character strings, including their homophones, are stored as ``red, vermilion, dirt, tan, scarlet...'' and the like. Similarly, the kanji headword for the kana character string ``ji'', including its homophones, is stored as ``show, shi, ji, ji, ji, temple...'' and so on. Each of these kanji headwords is expressed as its JIS kanji code, etc., as in the case of the conventional device.

On the other hand, in the conversion dictionary 3, words composed of multiple kanji such as two kanji characters (i.e. compound words)
The entry word is expressed by address information of the storage address of the dictionary 3 in which the plurality of kanji constituting the entry word are stored, and delimiter information indicating the division of readings for this entry word.

That is, for example, for the reading ``Akaji'',
Taking advantage of the fact that the reading can be broken down into two parts, ``aka'' and ``ji'', ``red'' in ``red'' is stored as the first headword ``red'' in the reading ``aka''.
Furthermore, since the ``character'' of the above ``red'' is stored as the third headword ``character'' of the reading ``ji'', the headword is expressed as ``1, 3'' as address information.

Note that the information "2" given as attribute information for the reading "Akaji" indicates that the reading "has a break at the second character from the beginning." In addition, if the character string indicating the reading cannot be broken down, the information indicating the break is given as ``0'', and if the kana string indicating the reading can be broken down into three or more, the information indicating the break is given as ``0''. For example, it is given as "2, 4", etc.

For example, for the reading ``Akashingo'', the above reading is changed to ``Aka/
Address information "1" and "Shin" are decomposed into "Shin/Go" and "Red" is stored for that "Aka".
Address information “5” where “trust” is stored for,
The address information ``4'' in which the ``go'' is stored for ``go'' gives the headword for the reading ``Akashingo'' as ``1, 5, 4 (red light)''.

Note that the delimiter information may be expressed as the number of delimiter characters, such as "2, 2" in the above example. Furthermore, if the corresponding word (kanji) is not stored as a headword for other readings in the dictionary 3, the headword may be stored as is as kanji information.

Thus, according to this device equipped with such a conversion dictionary 3, when a break is specified by the attribute information for the reading, the conversion unit 2 decomposes the reading according to the break information, and converts the decomposed reading into the decomposed reading. Find the headwords stored corresponding to each according to the address information and retrieve the headwords (kanji character strings).
You will get . In other words, it is possible to obtain the headword by finding the kanji notation that constitutes the headword according to the address information.

Furthermore, according to the configuration of the conversion dictionary 3 described above, a headword expressed by multiple kanji is expressed by the address information of each kanji and the delimiter information indicating the division of the pronunciation of the headword (idiom). Kanji directly
For example, instead of 2 bytes of data per character when expressed in JIS code,
It becomes possible to express the amount of data with less than 1 byte per character. Therefore, the capacity required for the conversion dictionary 3 can be significantly reduced, and for example, it is possible to store all the dictionary data in one chip semiconductor ROM.

Note that the present invention can be implemented with various modifications without departing from the gist thereof.
