Abstract

PURPOSE:To improve the convenience to use by providing a corresponding table to show the relation of the same type of pronunciation easy to be used erroneously, changing the original phonogram string to the similar phonogram string, and providing newly the means to refer to a converting dictionary. CONSTITUTION:When the syllable tale not to exist at a Chinese language is assembled, it is checked whether or not the syllable including the pin-in changed by referring to it exists as the syllable of the chinese language, and when the syllable exists, a processing 23 is returned. For example, when to input 'toh' (Chinese character), 'tong' is keyed in by mistake and a converting key is pressed down, the notational convention with the 'tong' as a heading is retrieved and 'toh' (Chinese character) does not exists. Thereafter, continuously, a similar pin-in corresponding table 4b is referred to, 't' having the similar pronunciation included in the 'tong' is replaced with 'd' and it is changed to 'dong.' By the new heading 'dong,' a converting dictionary 4a is retrieved again.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a Chinese text input device (hereinafter referred to as a Chinese text input device) that converts a Chinese phonetic character string into a Chinese character string and inputs the converted character string.

[Conventional technology]

Some Chinese text input devices used in information processing systems that process Chinese text utilize the reading method of Chinese characters. Such Chinese input devices input data according to the phonetic characters known as Binyin, which were established by the Chinese government, and convert them into Chinese characters.

Although the binyin mentioned above is carefully defined to accurately describe the standard pronunciation of Chinese, it is difficult to correctly distinguish similar pronunciations, or the distinctions are vaguely remembered and confused. This is seen not only among foreigners but also among Chinese people.

In particular, aspirated sounds (dpb+gtJ tz+zh) and aspirated sounds (
Regarding ttpy kv q+ Cr Ch), Chinese people unconsciously use different words, but often do not correctly remember the correspondence with phonetic characters. In other words, although I have learned spoken Chinese, I do not remember the phonetic characters that I learned at school. Therefore, the above-mentioned circumstances are one of the drawbacks that make it difficult for the conventional Chinese input device that inputs phonetic characters to be of practical use.The same situation also applies to the front nasal (n) and back nasal (ng). This is hindering the practical use of conventional Chinese input devices.

[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 correspondence table showing the relationship between similar pronunciations that are likely to be confused, and to change the original phonetic string to a similar phonetic string. It is an object of the present invention to provide a Chinese text input device that improves the above-mentioned drawbacks by having means for referring to a conversion dictionary.

[Failure to solve the problem]

The Chinese input device of the present invention inputs a Chinese phonetic character string, converts the phonetic character string into a Chinese character string, and displays the Chinese character string. It has a conversion dictionary that represents a group of Chinese character strings including homophones corresponding to the headings, and a similar bin-in correspondence table that indicates the relationship between similar pronunciations in Chinese phonetic characters, If there is no corresponding Chinese character string after searching the above notation, search the similar bin-yin correspondence table, change the bin-yins of similar pronunciations in the phonetic string to the corresponding bin-yins, and create a new table. The new phonetic character string is used as a phonetic character string, and the notation in the conversion dictionary is searched to find a corresponding Chinese character string.

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, the Chinese input device includes an input unit 1 having a bin ink key 1a and inputting examples of Chinese phonetic characters (examples of bin in characters), and a buffer unit 2 temporarily holding input data 100 including various control signals. , a conversion section 3 that converts Binyin character strings into Chinese character strings, a conversion dictionary 4a that shows the correspondence between Binyin character strings and Chinese character examples, and a similar Binyin correspondence table 4b that shows the relationship between similar pronunciations. 4, and a display control unit 5 that controls the display of the bin-in character string and the Chinese character string.
and a display section 6 that displays them.

The input unit 1 has a bin ink key 1a, and outputs input data 100 including various control signals along with bin in characters.

The buffer unit 2 inputs input data 100 and discriminates it to generate an input signal 101 representing bin-in, a conversion control signal 105 instructing conversion of bin-in to Chinese characters, and a display controlling the display of bin-in and Chinese characters. A control signal 106 is sent out.

The conversion unit 3 inputs the above input signal 101 and converts the search signal 1 to the dictionary unit 4 (described later) according to the conversion control signal 105.
While transmitting and receiving 02, Binyin is converted into Chinese characters and a pattern signal 103 is transmitted. Note that when displaying the Pinyin text to indicate the pressing of 1-1τ\binyin-I'-1a, the pattern signal 103 is sent without the above conversion process.

The display control section 5 receives the pattern signal 103 and sends out the display signal 104 in accordance with the display control signal 106.

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

Next, the configuration of the selection section 4 will be explained.

FIG. 2 is an explanatory diagram showing the configuration of the conversion dictionary 4a. In the figure, the conversion dictionary 4a consists of headings 11, which are a collection of phonetic strings indicating Chinese pronunciations, and notations 12, which are a collection of Chinese strings including homophone candy corresponding to each phonetic string. It is configured. In other words, Heading 1 that stores Pinyin
1 holds the notation 12 that stores the Chinese character string group. 0 Figure 3 (a) shows the assortative relationship between unwritten and aspirated sounds, which is one of the assortative bin-in correspondence table 4b. This is a correspondence table.

The correspondence table in the figure can be bidirectionally indexed and is referred to when it is necessary to change p1 from an aspirated sound to an aspirated sound, or from an aspirated sound to a pre-aspirated sound. FIG. 3(b) is another correspondence table of the similar Pinyin correspondence table 4b, which shows the similar relationship between front nasals and back nasals. The figure shows that there is a correspondence between pinyin characters or three characters. The correspondence table in the figure can also be bidirectionally indexed, and is referred to when it is necessary to change from a front nasal to a deep nasal, or from a deep nasal to a front nasal.

Similar Pinyin correspondence table 4b is shown in Figure 3 (a) and (
b)? By retaining it, it is possible to change both the assortative relationship between preaspirated and aspirated sounds or the assortative relationship between frontal nasals and deep nasals. However, if only one of them is required, it is sufficient to just maintain the corresponding correspondence table.

Figure 3 (C) is a syllable table of Chinese characters. In the figure, there are 102 syllables in which there is a correspondence between an aspirated and an aspirated sound, and there are 7 syllables in which either an aspirated or aspirated sound exists but there is no corresponding partner.

These are indicated by Δ marks. In addition, there are 59 sets of syllables in which there is a correspondence between a front nasal sound and a back nasal sound, and 22 syllables in which either a front nasal sound or a back nasal sound exists but there is no corresponding partner.
There are several. These are indicated by arrows and (arrows). Note that (yoshi) indicates the correspondence in the mouth sound, but there is no deep nasal sound in the mouth sound.

Therefore, when changing the assortative relationship between aspirated and aspirated sounds using the correspondence table in Figure 3(a), there are 211 types of syllables (102X2+7), 9 of which have no corresponding partner. There are 7 types. Furthermore, when changing the assortative relationship between front nasals and deep nasals using the correspondence table in Figure 3(b), the number of target syllable types is 140 (59 x 2
+22) Existing, of which there is no corresponding partner is 22
It is a seed. In other words, if the frequency of occurrence of each syllable is equal, the success rate of changing the assortative relationship between preaspirated and aspirated sounds will be approximately 97%, and the success rate of changing the assortative relationship between front nasals and deep nasals will be approximately 84%. can be changed to

When the assortative relationships are automatically changed as described above, syllables that do not originally exist may appear, and these are shown in FIG. 3(d). This figure is a list of syllables that can be located at any of the positions 1Δ1, '-X', or "(-X)" in FIG. 3(C) by the above-mentioned automatic change of like relationships. Therefore, after automatically changing the assortative relationship, it is possible to check whether the syllable is in the list shown in the figure.

When the changed syllable is one of the non-existent syllables shown in FIG. 3(d), the conversion dictionary 4a is not searched.

Note that the process of checking the presence or absence of a syllable after change as described above is an effective means for speeding up the Chinese sentence input operation, but it is not recommended when the conversion dictionary 4a is small or when illegal bin-in input rarely occurs. is not necessary.

FIG. 4 is a flowchart showing the operation of the Chinese sentence input device equipped with the dictionary section 4 as described above. In the figure, a process 21 is an input operation of a phonetic character string using Pinyin, and a process 22 is a display of a unit (heading) for converting the phonetic character string into a Chinese character string.

Process 23 is an operation for instructing the conversion of the above-mentioned heading.

Process 24 searches the conversion dictionary file 25 based on the above heading. Here, the conversion dictionary file 25 is configured as shown in FIG. 2 described above.

A process 26 determines whether the Chinese notation searched in the process 24 corresponds to the operator's request, and if it does, the conversion process for the previously input binin is completed. If it is not applicable, the process moves to process 27.

Process 27 determines whether all Chinese notations corresponding to the above heading have been searched, and if not, process 23
Go back and repeat the above steps. If no corresponding word is found even after searching all the Chinese expressions corresponding to the heading, the process moves to step 28.

Process 28 checks whether similar words with similar pronunciations have already been searched for the above heading. If the search has already been completed, the process returns to process 22 and waits for the operator's next operation; if not, the process moves to process 29.

Process 29 refers to the similar bin-in correspondence table 30 and performs process 22.
Change Pinyin with similar pronunciations included in the heading displayed in to the corresponding Pinyin. Here, the similar Pinyin correspondence table 30 is the same as already explained with reference to FIGS. 3(a) and 3(b).

Process 31 checks whether similar pinyin exists based on the result of process 29. Furthermore, if a syllable light that does not exist in Chinese as shown in FIG. 3(d) is incorporated, it is checked whether or not a syllable including the changed pinyin exists as a Chinese syllable by referring to it. If the heading is found, the process returns to step 23 and the search is repeated according to the changed heading.

If not, the process returns to step 22 and waits for the operator's next operation.

In this way, words with pronunciations similar to the heading are included in the search range, conversion processing is executed, and Chinese sentences are input. For example, with reference to Figures 2, 3, and 4, one bundle 1
When trying to input "tongl'f", if you accidentally press the "tong" e key and press the conversion key, "tongl'f: Search for the notation used as a heading, but 1 East" is not found. Then, referring to the similar Pinyin correspondence table, replace Mtl, which has similar pronunciations included in "tong", with ldl and change the heading to "
Change to 'dong'. And a new heading "d"
ong'', the conversion dictionary is searched again, 1 bunch 1 is found and displayed, and the Chinese sentence input is completed.Furthermore, if a front nasal or a back nasal is included, the input can be made in the same manner as above.

Note that although words in Chinese characters have been described above, Chinese sentences can also be input in the same manner as above for compound words and compound words made up of two or more Chinese characters.

That is, referring to the similar Pinyin correspondence table 4b, the Pinyin with similar pronunciation contained in the Binyin character string is sequentially replaced with the corresponding Pinyin to change it to a new Binyin character string, and this is used as a heading in the conversion dictionary 4a. can be searched. Therefore, the conversion dictionary 4a also includes Chinese words with two or more characters (not illustrated in FIG. 2).

).

〔Effect of the invention〕

As described above in detail, according to the Chinese input device of the present invention, a correspondence table showing the relationship between similar pronunciations is provided, and 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, it is possible to search the notation under similar headings to find the required Chinese notation. In other words, when a person who vaguely remembers Pinyin and is unable to distinguish between the shi pronunciations correctly, enters Chinese text by selecting the required Chinese notation from among the Chinese pronunciations, including similar words with similar pronunciations.

Furthermore, since the input data is changed and searched as described above, there is no need to add multi-functions modified from conventional conversion dictionaries.
