Abstract

PURPOSE:To register more word information in a fixed-size extension area by limiting information to be registered in the extension area to only headings and grammatical information. CONSTITUTION:When an operator inputs a heading, for example, 'kanji' with 4 key depression by a keyboard, this heading is transferred to a Kana (Japanese syllabary)-Kanji(Chinese character) conversion processing part 13. This Kana- Kanji conversion processing part 13 retrieves a fundamental constitution dictionary 11 with the number of key depressions as the key; and if the heading is found in a heading part 11a of the fundamental constitution dictionary 11, corresponding expression information and grammatical information are used to determine a candidate expression. The candidate expression is displayed on a display device thereafter. If heading 'kanji' inputted by key depression is not found in the heading part 11a of the fundamental constitution dictionary 11 and the operator newly registers it n an extension area 12, only the heading and grammatical information are written in the heading part 12a and a grammatical information part 12b of the extension area 12, and a corresponding Kanji expression is stored on a floppy disc device 15.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a kana-kanji conversion dictionary expansion method, and more particularly to a kana-kanji conversion dictionary expansion method used for kana-kanji conversion in a Japanese input device.

[Conventional technology]

The Kana-Kanji conversion dictionary is constructed by storing a large number of word information as a code, which is a set of headings, kanji notations (not necessarily including kanji), and grammatical information. Therefore, each word information is a variable length record whose length varies depending on the number of homophones characteristic of Japanese.

In the conventional kana-kanji conversion dictionary expansion method, if the heading corresponding to the key manually entered heading is not stored in the basic constituent dictionary and the kana-kanji conversion dictionary is expanded by registering new word information, the heading, kanji The Kana-Kanji conversion dictionary was expanded by registering word information with notation and grammatical information in the expansion area. For this reason, for example, the heading “Kanta °
When the Kana-Kanji conversion dictionary is expanded by repeated registrations, “
Kanji expressions such as kanji°, “confusion°,” “secretary゛,” etc. will be registered one after another, and if the size of the expansion area is limited, the number of kanji notations that can be expanded will naturally increase. and the number of records would be limited.

[Problem that the invention seeks to solve]

In the conventional kana-kanji conversion dictionary expansion method described above, word information consisting of headings, kanji notations, and grammatical information is registered as le codes to expand the kana-kanji conversion dictionary. If this is set, the number of expandable records will be limited if a large number of records with many homophones are registered, that is, the number of records that can be expanded will vary depending on the number of homophones.

Another disadvantage is that in order to register more records, a larger expansion area is required.

In view of the above-mentioned points, an object of the present invention is to provide a kana-kanji conversion dictionary expansion method that allows registering a large number of kanji notations without securing a large expansion area on the main memory. .

[Means for solving problems]

The Kana-Kanji conversion dictionary expansion method of the present invention uses headings.

A basic dictionary that stores a large number of kanji notations and grammatical information as one set, an extended area that can register a large number of headings and grammatical information as one set, and an auxiliary that stores kanji notations that correspond to the headings registered in this extended area. a storage device, a kana-kanji conversion processing means for performing kana-kanji conversion processing of a heading by referring to the basic constituent dictionary and the extended area, and a heading is registered in the extended area by the kana-kanji conversion processing means; and a notation search means for searching the kanji notation corresponding to the heading from the auxiliary storage device when the heading is detected.

[Effect]

In the kana-kanji conversion dictionary expansion method of the present invention, the basic constituent dictionary stores a large number of headings, kanji notations, and grammatical information as one set, and the expansion area can store a large number of headings and grammatical information as one set. The memory surface stores the kanji notation corresponding to the heading registered in the extended area, the kana-kanji conversion processing means performs the kana-kanji conversion process for the heading by referring to the basic constituent dictionary and the extended area, and the notation search means stores the kanji notation corresponding to the heading registered in the expanded area. When the kanji conversion processing means detects that a heading is registered in the extended area, the kanji notation corresponding to the heading is searched from the auxiliary storage device.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 2 is a block diagram showing a Japanese language human power device to which the kana-kanji conversion dictionary expansion method according to an embodiment of the present invention is applied.

This Japanese input device consists of a keyboard 1 for manually inputting headings as kana character strings, a main unit 2 for displaying and displaying the first results of kana-kanji conversion processing, and a main unit 2 for inputting the manually inputted headings and kana-kanji conversion results. The main part thereof is composed of a display device 3 for displaying images.

Referring to FIG. 1, one embodiment of the present invention includes a heading portion 1
1a1 A basic constituent dictionary 11 consisting of a notation section 11b and a grammatical information section 11C, in which a large number of headings, kanji notation, and grammatical information are stored as a code; and a dictionary 11 consisting of a heading section 12a and a grammatical information section 12b, in which headings and grammatical information are stored. An extended area 12 that can register a large number of kanji codes, a kana-kanji conversion processing unit 13 that performs kana-kanji conversion processing, a notation search unit 14 that searches for kanji notations corresponding to headings, and corresponds to the headings registered in the extended area 12. The system includes a floppy disk device 15 as an auxiliary storage device for storing kanji notation.

The basic configuration dictionary 11 is formed on a ROM (read only memory) included in the main device 2, and the expansion area 12 is secured on a main memory (not shown) included in the main device 2. Further, the floppy disk device 15 is incorporated into the main body device 2.

Next, the operation of the kana-kanji conversion dictionary expansion method of this embodiment configured as described above will be explained.

If the operator manually inputs the heading "Kanji" using the keyboard 1 by pressing four keys, this heading is delivered to the kana-kanji conversion processing section 13.

The kana-kanji conversion processing unit 13, which has been handed over the heading, searches the basic composition dictionary 11 using the number of key strokes, for example 4, as a key, and if the heading exists in the heading part 11a of the basic composition dictionary 11, it searches the corresponding notation information. and grammatical information to determine candidate notations. After this, the candidate notations are displayed on the display device 3.

On the other hand, if the entry ``kanno'' entered by keystroke does not exist in the entry section 11a of the basic configuration dictionary 11 and the operator newly registers it as an extension, then the entry section 12a and the grammar information section 12b of the extension area 12 Only headings and grammatical information are written into the floppy disk device 15, and the corresponding kanji notation is stored on the floppy disk device 15.

If the same heading is entered on the keyboard 1 after the heading “kanno゛” has been registered as an extension, the kana-kanji conversion processing unit 13 searches the basic constituent dictionary 11 and the extended area 12 in order, and searches the extended area 12. The presence of a heading is detected in .Then, the validity of the conversion is confirmed by grammatical analysis, and when this is [if, the number of input keystrokes 4 and the record entry rank are passed to the notation search unit 14. Then, the kanji notation is searched, and then the homophones are determined.

After this, when a further kanji notation is extended and registered under the heading "kanno°", the kanji notation is additionally registered on the floppy disk device 15 while the record size of the extension area 12 remains unchanged.

〔Effect of the invention〕

As explained above, the present invention limits the information to be registered in the extended area to only headings and grammatical information when registering extended words that are not stored in the basic constituent dictionary, and stores the kanji notation on the auxiliary storage device. This has the effect that more word information can be expanded and registered in an expansion area of a fixed size, regardless of the number of homophones.
