Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a Japanese input method, and more specifically, for obtaining a correct Kanji / Kana character string based on an input Kanji / Kana character string. The present invention relates to a character string correction method.

(Prior art and its problems) With the recent spread of Japanese input devices such as word processors, unskilled people with little experience in Japanese input and general users who are not very familiar with Kanji usage But,
There have been many opportunities to use these devices.

Among the Japanese input methods, there is a pen-tatch input method that allows you to enter kanji and kana character strings while picking up kanji on the board with a touch pen, a code input method that allows you to enter a code that corresponds to each kanji, and actually use kanji by hand. Although the online handwritten character recognition method, which is entered by writing, is an effective method that allows the user to directly input the desired Kanji, since the input unit is a character, the entered Kanji character string is correct in Japanese. It is the user's responsibility to ensure that it is a thing. For this reason, for example, even if the user mistakenly inputs the character string “slow” and inputs “delete”, it is impossible to know that this writing method is incorrect.

(Object of the Invention) An object of the present invention is a character string correction method for outputting a probable Kanji / Kana character string candidate in place of a mistaken spelling or usage of a Kanji / Kana character string that a user wants to input. To provide.

(Structure of the Invention) According to the present invention, the kana character in the input kanji kana character string and the kanji dictionary containing the kanji reading based on each kanji character can be obtained by searching the kanji dictionary. A reading character string creating means for combining readings to create one or a plurality of reading character strings, and a kana for converting the reading character strings into kana-kanji characters and performing a grammar test to eliminate inappropriate kanji kana character strings. 1 passed from the kanji conversion means and kana kanji conversion means
All or a plurality of Kanji / Kana character strings are displayed, and when a plurality of Kanji / Kana character strings are obtained, one of the Kanji / Kana character strings is determined and output according to a selection instruction from the user. It is possible to obtain a character string correction method characterized by including a character string output means for

(Example) Hereinafter, the Example of this invention is described in detail, referring drawings.

FIG. 1 shows an embodiment of the present invention. Reference numeral 1 is a control unit that manages the overall control, 2 is an input means for inputting a kanji / kana character string, 3 is a kanji dictionary storing kanji readings, and 4 is a kanji dictionary 3. A reading character string creating means for creating one or a plurality of reading character strings by combining the reading of each kanji obtained by searching and the kana character in the input character string, and 5 is at least a word reading Is a word dictionary storing notation and part-of-speech information, 6 is a kana-kanji conversion means for converting the reading character string into kana-kanji by repeating the search of the word dictionary 5, and 7 is a plurality of kana-kanji conversion results. It is a character string output means for indicating and determining a necessary character string from word candidates and outputting it when the individual kanji kana character string candidates are obtained. Further, FIG. 2 shows an outline of the flow from the input kanji-kana character string to the correct kanji-kana character string using the embodiment of FIG.

Here, a procedure for correcting the above-mentioned "removal" will be described as an example. However, for convenience of explanation, it is assumed that the kana-kanji conversion means 6 is configured to receive a kana character string written with segmentation.

First, the Chinese character kana character string "removing" is input from the input means 2 by, for example, direct input on a character-by-character basis or phrase extraction from the already input kanji kana character string (101 in FIG. 2).

In addition to the above-mentioned pentach input, input in character units,
It is also possible to perform display selection by selecting a kanji group displayed after being given a kanji reading, using already entered text data, or inputting a character string from the outside. Extraction of bunsetsu can be done, for example, by IPSJ Computational Linguistics Study Material 15-2 “Japanese bunsetsu certification”.
Automatic processing by the method described in (1978),
This can be done by the user's range designation instruction. Also,
It is also possible to check beforehand whether the extracted phrase sequence is correct in Japanese by dictionary lookup, grammar test, etc., and to process only those that are not a phrase.

The character string “removing” input from the input means 2 is sent to the reading character string creating means 4 under the control of the control unit 1. The reading character string creating means 4 checks the kanji dictionary 3 based on the kanji characters "removal" and "line" that form the obtained character string "removing", and extracts the reading of each kanji character (102 ), And the remaining kana characters "su" and "ru" are combined to create a possible reading character string (103). If there are "jiyo" and "ji" as readings of "division" and "ko" and "giyo" as readings of "line" in the kanji dictionary 3, the reading character string creating means 4 From these readings, the reading character strings “jiyokousu”, “jiyokiyosu”, “jijikousu”, and “jigiyosu” are created and passed to the kana-kanji conversion means 6.

Under the control of the control unit 1, the kana-kanji conversion means 6 performs kana-kanji conversion based on the read character string while repeating the checking and grammar verification of the word dictionary 5 (104).

Here, in the word dictionary 5, for "jiyoko"
(Noun), "Xu" (Sahen), "Matter" (Noun), "Tourism" (Noun), "Prescription" (Noun), "Business""(Noun)and" terrain "(noun) are stored. The kana-kanji conversion means 6 extracts these words and performs a grammar test to exclude only the correct bunsetsu and unsuitable ones. In this example, the word "suru" exists at the end,
As a result, only "slow" in which "suru" is connected to "slow" which is a sahen noun remains and is passed to the character string determining means 7.

The character string output means 7 determines a desired character string by a method of displaying all candidates passed from the kana-kanji conversion means 6 and allowing the user to select them (105), and outputs this (106). ). In this example, since there is only one "slow", this can be output.

By these series of procedures, "excrement" is "slow"
Can be corrected to

(Effects of the Invention) By using the present invention, even when a user makes a mistake in spelling or usage of a kanji / kana character string, a correct character string candidate is automatically extracted / presented, so that The work of character input and typographical error correction can be reduced.
