Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention converts a Chinese phonetic character string into a Chinese character string and inputs the converted Chinese character string (hereinafter referred to as a middle-sized input device). Regarding

[Conventional technology]

Some Chinese input devices used in information processing systems that process Chinese sentences utilize the reading of Chinese characters. In such a character input device, input is performed according to the description of the phonetic characters called Pinyin (sound) established by the Chinese government, and it is converted into Chinese characters.

The above Pinyin is rigorously defined to accurately describe the standard pronunciation of Chinese, but it is difficult to correctly distinguish similar pronunciations, or the distinction is vaguely remembered and confused. Not only foreigners, but many Chinese. Especially for apathy sounds (d, b, g, j, z, zh) and aerobic sounds (t, p, k, q, c, ch), Chinese people unconsciously use them properly, but Often do not remember the correct response. That is, although I have learned Chinese as a spoken language, I do not remember well the phonetic alphabets I learned at school. Therefore, the above situation is one of the drawbacks that it is said that it is difficult for the conventional Chinese sentence input device by phonetic character input to be practically used.

In addition, the same situation as described above also applies to the front nasal sounds (n) and the rear nasal sounds (ng), which hinders practical use of the conventional Chinese sentence input device.

[Problems to be solved by the invention]

The problem to be solved by the present invention, in other words, the purpose of the present invention is to provide a correspondence table showing the relationship of similar pronunciations that are easily confused, and change the initial phonetic character string to a similar phonetic character string. Another object of the present invention is to provide a Chinese text input device that improves the above-mentioned drawbacks by providing a means for referring to a conversion dictionary.

[Means for solving problems]

The present invention, in a Chinese sentence input device for inputting a Chinese phonetic character string, converting the phonetic character string into a Chinese character string and displaying the same, corresponds to the headline that is the phonetic character string and this heading. A conversion dictionary having a notation that is a Chinese character string group of homophones, and a similar Pinyin correspondence table that indicates a relationship of similar pronunciations for a phonetic or pronoun, and searches for the notation based on the heading. When the corresponding Chinese character string disappears, the similar Pinyin correspondence table is searched and the Pinyin in the phonetic character string is changed to a corresponding Pinyin of the same pronunciation to make a new phonetic character string, The corresponding Chinese character string is searched for by searching the notation of the conversion dictionary with the new phonetic character string as a heading.

〔Example〕

Hereinafter, a Chinese text input device according to the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.
In the figure, the Chinese input device has a pinyin key 1a for inputting a Chinese phonetic character string (pinyin character string), and a buffer part 2 for temporarily holding input data 100 including various control signals. And a conversion unit 3 for converting a Pinyin character string into a Chinese character string, a conversion dictionary 4a showing the correspondence between the Pinyin character string and the Chinese character string, and a dictionary unit having a similar Pinyin correspondence table 4b showing the relation of similar pronunciations. 4, a display control unit 5 that controls the display of Pinyin character strings and Chinese character strings, and a display unit 6 that displays them.

The input unit 1 has a pinyin key 1a and sends out input data 100 including various control signals together with pinyin characters.

The buffer unit 2 inputs the input data 100, discriminates the input data 101, represents an input signal 101 representing pinyin, a conversion control signal 105 instructing conversion from pinyin to Chinese characters, and a display controlling display of Pinyin or Chinese characters. Control signal 106
Is sent.

The conversion unit 3 inputs the above-mentioned input signal 101, converts the Pinyin into Chinese characters and outputs the pattern signal 103 while sending the dictionary unit 4 (described later) and the search signal 102 according to the conversion control signal 105. When the pinyin character is displayed to indicate the depression of the pinyin key 1a, the above conversion process is omitted and the pattern signal 103 is transmitted.

The display control unit 5 receives the pattern signal 103 and outputs the display signal 104 according to the display control signal 106.

The display unit 6 inputs the above-mentioned display signal 104 and displays it so that the operator can visually recognize it.

 Next, the configuration of the dictionary unit 4 will be described.

FIG. 2 is an explanatory diagram showing the structure of the conversion dictionary 4a. In the figure, the conversion dictionary 4a is composed of a heading 11 which is a set of phonetic character strings indicating Chinese pronunciation and a notation 12 which is a set of Chinese character string groups including homophones corresponding to each phonetic character string. It is configured. That is, the notation 12 storing the Chinese character string group corresponding to the headline 11 storing Pinyin is held.

FIG. 3 (a) is a correspondence table showing the similar relationship between the silent and aerobic sounds, which is one of the similar Pinyin correspondence table 4b. The correspondence table in the figure is bidirectionally indexable, and is referred to when it is necessary to change from aerobic to aerobic or from aerobic to apathetic. Also, FIG. 3 (b) is a similar Pinyin correspondence table.
It is a correspondence table showing a similar relationship between front nasal sounds and back nasal sounds which is another one of 4b. In the same figure, it is shown that there are correspondences with two or three pinyin characters. The correspondence table in the figure is also bidirectionally indexable, and is referred to when it is necessary to change the front nasal sounds to the back nasal sounds or the back nasal sounds to the front nasal sounds.

The same Pinyin correspondence table 4b holds both FIG. 3 (a) and FIG. 3 (b) above so that both the akinetic and aerobic related changes or the prenasal and deep nasal related changes can be made. It is possible. However, when only one of them is required, only the corresponding correspondence table needs to be held.

FIG. 3 (c) is a syllable table of Chinese characters. In the figure, there are 102 syllables in which there is a correspondence between apathetic and aerobic, and there are 7 syllables that have either apathetic or aerobic but no corresponding partner. These are marked with a triangle. There are 59 syllables in which there is a correspondence between the front nasal and the back nasal.
There are 22 pairs, and there are either the front nasal or the back nasal, but there is no corresponding partner. These are marked with * and (*). Note that (*) indicates the correspondence in the mouthpiece sound, but there is no back nasal sound in the mouthpiece sound.

Therefore, when the similar relation between apathic and aerobic is changed according to the correspondence table of FIG. 3 (a), there are 211 kinds (102 × 2 + 7) of target syllables, and there is no corresponding partner. There are seven types. Moreover, when the similar relation between the front nasal and the back nasal is changed according to the correspondence table of FIG. 3 (b), there are 140 kinds (59 × 2 + 22) of target syllables, and among them, there is no corresponding partner. There are 22 species. That is, if the frequency of occurrence of each syllable is equal, the success rate of about 97% is automatically changed when the similar relationship between apathy and aerobic is changed, and about 84% is automatically changed when the related relationship of front nasal and back nasal is changed. Can be changed to

When the similar relation change is automatically executed as described above, syllables that do not originally exist may appear, and they are shown in FIG. 3 (d). This figure is a list of syllables that are positioned at any of the positions of "Δ", "*", or "(+)" in FIG. 3 (C) due to the above-described automatic change in the like relationship. Therefore, after automatically changing the similar relation, it is possible to confirm whether or not the syllable is in the list shown in FIG. The syllable after the change is shown in FIG. 3 (d).
If it is one of the nonexistent syllables shown in, the conversion dictionary
Don't search for 4a.

It should be noted that the processing for confirming the presence or absence of the changed syllable as described above is an effective means for speeding up the middle-division input operation, but it does not frequently occur when the size of the conversion dictionary 4a is small or illegal pinyin input occurs. It is unnecessary in some cases.

FIG. 4 is a flow chart showing the operation of the Chinese sentence input device provided with the dictionary unit 4 as described above. In the figure, a process 21 is an input operation of a phonetic character string by Pinyin, and a process 22 displays the phonetic character string as a unit (heading) for converting the phonetic character string into a Chinese character string. Then, the process 23 is an operation for instructing the conversion of the above-mentioned headline.

Process 24 is a conversion dictionary file based on the above heading
Search for 25. Here, the conversion dictionary file 25 is the above-mentioned second
It is configured as shown.

A process 26 determines whether or not the Chinese notation retrieved by the process 24 corresponds to the operator's request, and if it corresponds, ends the conversion process corresponding to the previously input pinyin. If it is not applicable, the process proceeds to process 27.

The process 27 determines whether or not all the Chinese expressions corresponding to the above headings have been searched, and if not, the process returns to the process 23 to repeat the above process procedure. Then, when there is no corresponding word even if all the Chinese expressions corresponding to the headline are searched, the process 28 is performed.

The process 28 confirms whether or not a similar word having the same pronunciation has already been searched for the above heading. Process if already searched
The process returns to step 22 and waits for the next operation by the operator. If not, the process proceeds to step 29.

The process 29 refers to the similar pinyin correspondence table 30 and changes the pinyin having the similar pronunciation included in the heading displayed in the process 22 to the corresponding pinyin. Here, the similar Pinyin correspondence table 30 is as already described with reference to FIGS. 3 (a) and 3 (b).

The process 31 confirms whether there is a similar pinyin based on the result of the process 29. Further, if the syllable table that does not exist in Chinese in FIG. 3 (d) is incorporated, it is checked whether or not the syllable including the changed Pinyin exists as a Chinese syllable by referring to it. If so, the process returns to step 23 and the search is repeated according to the changed heading. If not, the process returns to step 22 to wait for the next operation by the operator.

In this way, the conversion processing is executed by including the word having a pronunciation similar to the headline in the search range, and the Chinese sentence is input. For example, referring to FIGS. 2, 3, and 4,
If you mistakenly key in "tong" and press the conversion key while trying to enter "east," the search will start with "tong" as the heading, but "east" does not exist. Then, referring to the similar pinyin correspondence table, "t" having a similar pronunciation included in "tong" is replaced with "d" and the heading is changed to "dong". Then, by searching the conversion dictionary again by the new heading "dong", "East" is found and displayed, and the Chinese sentence input is completed. Further, when the front nasal sound or the back nasal sound is included, the input can be performed in the same manner as above.

Although the above description has been made with reference to a word consisting of one Chinese character, in the case of a compound word or a compound word consisting of two or more Chinese characters, Chinese text can be input in the same manner as above. That is, referring to the similar Pinyin correspondence table 4b, the Pinyin having the similar pronunciation included in the Pinyin character string is sequentially replaced with the corresponding Pinyin to change to a new Pinyin character string, and this is used as a heading for the conversion dictionary 4a. Can be searched. Therefore, the conversion dictionary 4a also includes Chinese characters with two or more characters (not shown in FIG. 2).

〔The invention's effect〕

As described above in detail, according to the Chinese sentence input device of the present invention, a correspondence table showing the pronunciation relations of the same kind is provided, the original phonetic character string is changed to a similar phonetic character string, and the conversion dictionary is referred to. Therefore, when there is no corresponding Chinese notation under the original heading, there is an effect that the notation under a similar heading can be searched for the required Chinese notation. That is, a person who remembers the pinyin vaguely or who cannot distinguish the pronunciation correctly makes a key-in, and can input characters while selecting the necessary one from the Chinese notation including similar words with similar pronunciation.

Further, since the input data is changed and the search is performed as described above, there is also an effect that it is not necessary to modify the conventional conversion dictionary or add a function.
