Abstract

PURPOSE:To check justice of a pin-in character string by comparing a specific character of a phonetic symbol string or the attribute of arrangement of >=2 specific characters with the spelling rule of phonetic symbols and deciding the justice of said phonetic symbol string when coincidence is obtained from said comparison. CONSTITUTION:In a process 11 a phonetic symbol, e.g., 'pin-in' of a Chinese language is supplied with a key and the attribute of the phonetic symbol is checked in a process 12. This attribute is compared with the spelling rule in a process 14. A process 16 is shifted to a process 18 and to a process 17 when the key-in justice is decided and not respectively. In the process 17 an alarm display is performed to point out an operating error; while the justice of a key-in phonetic symbol string is checked in the process 18 before the phonetic symbol character is converted into a Chinese character string. The arrangement of the 1st and 2nd characters of finals of a syllable consisting of initials and finals is extracted. The type of the 2nd character is limited by the type of the 1st character and therefore the wrong key-in actions are excluded. Then it is possible to exclude the wrong key-in actions by making use of a fact that the 1st character of the finals following to a specific initials.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a Chinese text (hereinafter referred to as "Chinese text") input check method, particularly a Chinese text method for checking the validity of Chinese phonetic character strings in Chinese text input. Regarding input checking method.

[Conventional technology]

A Chinese input device is essential in an information processing system that processes Chinese sentences. As an input method for such a Chinese input device, a method is generally used in which Chinese characters are encoded based on their form, reading method, or a combination of these.

There are two types of phonetic characters that represent the reading of Chinese: pinyin, which was established by the Chinese government, and pinyin, which was used in the past even before pinyin was established. Pinyin is the mainstream in China today, but in the past it was mainly limited to some regions such as Taiwan.

In a Chinese input device that inputs data according to the Pinyin description described above and converts it into Chinese sentences, one method is to key in Pinyin characters one by one, or to set a voice initial key and a rhyme final key. There is a key-in method, and each method allows you to enter a huge variety of Chinese characters using about a dozen keys.

However, when writing Chinese using Pinyin, there are rules for distinguishing between similar or similar pronunciations, and prohibitions against syllables that do not actually exist. Requires extensive knowledge and skill. In other words, the pinyin-based Chinese input device has the disadvantage that it is not easy to use even for Chinese people. Furthermore, it can be said to be of little use to foreigners who have little knowledge of Pinyin or China.

[Problem that the invention seeks to solve]

The problem to be solved by the present invention, in other words, the purpose of the present invention is to provide a Chinese input checking method that eliminates ambiguous input by checking the validity of the keyed-in Pinyin character string and improves the above drawbacks. It's about doing.

[Means for solving problems]

The Chinese input checking method of the present invention is a Chinese input checking method for checking the validity of the phonetic string when converting a Chinese phonetic string into a Chinese character string. means for extracting the attributes of characters or the attributes of a specific sequence of two or more characters and comparing the attributes with spelling rules for phonetic characters; and when the two match by the means, the phonetic string is valid. It is configured with a hand memi that determines that it is.

〔Example〕

Hereinafter, the Chinese input checking method according to the present invention will be explained with reference to the drawings.

FIG. 1 is a flowchart showing an overview of the processing method JIQ of the present invention. Process 11 is Chinese phonetic characters (for example, Pinyin)
This is an operation of keying in , and the process 12 investigates the attributes of the above-mentioned phonetic characters. Attributes include initials/finals, features of character types, etc., details of which will be described later. The above attributes are stored in the attribute information file 13.

Process 14 compares the above attributes with spelling rules.

The spelling rules are stored in a spelling rule file 15.

Process 16 indicates a judgment based on the above comparison results, and when it is determined that the key-in is correct, the process moves to process 18, and when it is judged that the key-in is incorrect, the process moves to process 17.

Process 17 is an alarm display that points out the error in operation and prompts correct key-in, and process 18 instructs to continue key-in the next phonetic character or to instruct conversion to Chinese characters.

This Chinese input checking method checks the validity of a keyed-in phonetic string before converting the phonetic string into a Chinese character string. Chinese syllables are generally expressed as
There are some syllables that are composed of the final word, but there are also some syllables that only have the final word. However, some syllables with only a “voice initial” or “voice initial +
There are no syllables with the ``vocal mother''. Therefore, as a check regarding the key-in of initials, it is necessary to exclude the key-in of two or more initials in succession, and specifically, in Japanese word processors that use Roman alphabet input, only the last keyed-in character should be valid. K has already been implemented. This method can also be used to check Chinese input using Pinyin.

FIG. 2 shows a list of the extracted sequences of the first and second letters of the finals of syllables consisting of "vocal initial + final". In the figure, the first characters 11Ca,,o.

There are six types: e, i, u, and U, and there are two to four types of second letters following these. In other words, since the type of the second character is limited according to the type of the first character, this feature is utilized to eliminate unauthorized key-ins.

In addition, the display of Chinese syllables in Pinyin is uei, uen.
.

and ueng are ui, un, and weng, respectively, in the actual syllable descriptions that follow the initial. This is shown in parentheses. Therefore, the long sword check should be performed on the final description in parentheses.

FIG. 3 shows a list of extracted syllables that have different descriptions when there is no initial for syllables that consist only of a "final".

In the figure, the first letter is i, u.

Or, if the final word of i゛ is written as \, it will not be a syllable consisting only of the final word. In other words, i is yiK.

U is changed to wu, and U is changed to yu (some of them are irregular). The features shown in FIG. 2 exist for the parts of such syllables excluding y or W.

Therefore, for syllables where y or W is the first letter, all of the above checks can be carried out by regarding the part excluding y or W as the final word. Note that ong cannot be a syllable by itself.

FIG. 4 shows that the first letter of the final that follows a particular initial is limited. In other words, the first letter of the final after the initial j, q or X is limited to i or U.

Furthermore, the first letter of the final after g+k or h is a,
e, o or U. Therefore, by utilizing such features, unauthorized key-in can be eliminated.

FIG. 5 is a flowchart showing the operation procedure of the above-mentioned Chinese input checking method. In the figure, process 31 indicates an operation of keying in a vocal initial or a rhyming final by operating the input unit l. Processing 32 then determines whether the keyed-in pinyin is a vocal initial or a rhyming final, and if it is a vocal initial, the process goes to processing 33, and if it is a rhyming final, processing goes to process 4.
1 respectively.

Process 33 checks the initial keyed in in process 31, and if it is j, q% or The process 34 is the above j.

Key in the final word following q% or X. Further processing 3
Step 5 checks the first character of the final word keyed in in process 34, and if it is it or U, the process moves to process 45, and if it is any other character, an alarm is displayed to prompt the user to key in the correct final character. Return to process 34.

Process 36 checks the initial keyed in in process 37, and if it is gsk- or h, the process goes to process 37, and if it is other than 1 or h in J tqsX sg *, the process goes to process 39. Then, in step 37, the final word following % or h is keyed into g. Furthermore, process 38 checks the first letter of the final word that was keyed in in process 37, and if it is a, e, o, or U, the process moves to process 45, and if it is any other character, K is the correct final character. An alarm prompting key-in is displayed and the process returns to step 37.

Similarly, the process 39 keys in the final that follows the initial other than j tqsX sg ski or h. Then, a process 40 checks the first character of the final word that was keyed in in the process 39, and if it is valid, moves to process 45-\, and if it is not valid, displays an alarm to prompt the user to key in the correct final character. Return to process 39.

Process 45 checks the final keyed in as described above, and if it is a - character, the process goes to process 48, and if it is two or more characters, it goes to process 46.

Process 46 examines the combination of the first and second letters of the final to check its validity. When the process 47 determines that the above-mentioned two-character sequence is valid, the process proceeds to process 48, and when the sequence is valid, the process proceeds to process 31. Process 48 indicates the next operation after completing the key-in and check-in of one syllable.

Process 41 checks the pinyin keyed in in process 31 when it is the final word, and when it is ong or the first character is i, u, or i, an alarm is generated to prompt the user to key in the correct final word. Display and process 31
Return to If the final result is other than the above, the process moves to step 42.

Process 42 checks the final keyed in in process 31 again, and if the first character is yt or W, process 43
, if it is other than y or W, the process moves to step 45, respectively.

Process 43 is a process in which the part of the first character excluding y or W is regarded as the final part, and process 44 is a process in which the character string regarded as the final part in process 43 is checked, and the first character is a.
, e, i, o, or U, the process moves to step 45, and if it is different from the above, an alarm is displayed to prompt the user to key in the correct final word, and the process returns to step 31. In the process 45 and subsequent steps, the same checks as for the final of syllables having a vocal initial meeting are carried out in accordance with the above-mentioned routine.

〔Effect of the invention〕

As explained in detail above, according to the Chinese input checking method of the present invention, the validity of the keyed-in character string is checked using the features of the keyed-in character string, so ambiguous key-in operations are eliminated and Chinese input is correct. It has the effect of being able to do the following.
