Abstract

PURPOSE:To register a large number of words as the field information and to instantaneously ensure the automatic deciding effect of the fields by storing the descriptions of words and the information on the fields where these words belong with correspondence secured between them and then outputting the words with preference after deciding the corresponding fields in accordance with the inputted KANA (Japanese syllabary) character strings. CONSTITUTION:When a field decision/selection key is inputted, a selection display state is secured for the selection of the deciding (reflecting) timing of the field that is automatically decided by the KANA/KANJI(Chinese character) conversion (b). The selection display state is changed to the 'KANA/KANJI conversion operation start time' (c), and a 'selection' state is inputted with a key. Then the Japanese reading of the KANJI is inputted with the HIRAGANA (cursive forme of Japanese syllabary), and the reading input of the KANA/KANJI conversion is displayed (d). When a conversion key is inputted, a character string candidate that undergone the KANA/KANJI conversion is displayed (e). The doctor words having the medical field information are included in the KANA/KANJI conversion candidates. Therefore the medical field is automatically set for conversion and the 'doctor' having the medical field information is first shown. Then other conversion candidates are displayed in the order of word frequency.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing method and apparatus for efficiently determining a phrase to be converted and output from homonymous phrases in the kana-kanji conversion process.

[0002]

2. Description of the Related Art Conventionally, a Japanese word processor that creates a Japanese sentence using Kana-Kanji conversion for converting an input reading into a Kana-Kanji mixed sentence has been widely used.

However, Japanese has a characteristic that there are many words (homonyms) and phrases having the same reading but different meanings. In order to deal with this, the homonyms must be correctly selected according to the situation. The homonym synonym selection technology for conversion and output has become an important technology in kana-kanji conversion processing.

As a technique for selecting such homonyms, in addition to the first dictionary in which the word processing is associated with the notation of the word in the document processing device, each notation character string of the first dictionary and its notation. The third dictionary is provided with a second dictionary that stores application field information of written words, and a third dictionary that stores application field information of words that read this kana character string in association with each other. The field of the sentence being created is discriminated from the kana character string input by, and the second dictionary is used to give priority to the word applied to the field discriminated from the homonyms and to be the conversion candidate. A character processing device having a function of performing has been proposed.

[0005]

However, in the above method, the third dictionary for discriminating the field by the kana character string contains kana character strings with many homophones or homophones with similar frequencies. There was a drawback that a certain kana character string could not be registered.

Further, according to the above, it is difficult to obtain an important keyword for discriminating the field, and the number of registered words is very small.

Therefore, in the conventional method, the effect of discriminating the field was not obtained so much in the actual document creation.

[0008]

In order to solve the above problems, according to the present invention, an input kana character string is stored in association with the reading of a word and the information of the word including notation. In the character processing method for executing a kana-kanji conversion process for converting a kanji-kana mixed sentence by referring to the dictionary, the information of the word notation and the field to which the word of the notation belongs is stored, and input in the kana-kanji conversion process. Before the conversion of the Takanaka character string is started, the field to which the word to be converted belongs is determined by referring to the information on the field, and the words belonging to the field are preferentially output as conversion candidates.

According to another aspect of the present invention, a kanji character is referred to by referring to a dictionary in which an input kana character string is stored in association with the word reading and the information of the word including notation. In a character processing method for executing a kana-kanji conversion process for converting to a kana-mixed sentence, storing information of a word notation and a field to which the word of the notation belongs, in the kana-kanji conversion process, before starting conversion of an input kana character string. In addition, by referring to the information of the field, the execution timing of the process of determining the field to which the word to be converted belongs is selectively set, the determination is executed at the set timing, and the determination is made as the conversion candidate. The feature is that the words belonging to the field are preferentially output.

Further, the character processing device stores a dictionary in which word readings and word information including notations are stored in association with each other, input means for inputting characters, and kana characters input by the input means. Kana-Kanji conversion means for converting a string into a kanji-kana mixed sentence by referring to the dictionary, field information storage means for storing word notation and field information to which the word of the notation belongs, and information in the field information storage means See
The kana-kanji conversion means includes a discrimination means for discriminating a field to which a word to be converted belongs, and a control means for controlling the kana-kanji conversion means to preferentially output a word belonging to the field discriminated by the discrimination means as a conversion candidate. ..

Alternatively, the character processing device stores a dictionary in which word readings and word information including notations are stored in association with each other, input means for inputting characters, and kana characters input by the input means. Kana-Kanji conversion means for converting a string into a kanji-kana mixed sentence by referring to the dictionary, field information storage means for storing word notation and field information to which the word of the notation belongs, and information in the field information storage means Referring to, the discriminating means for discriminating the field to which the word to be converted belongs, the selecting means for selecting the discriminating execution time of the discriminating means, and the discriminating means for executing the discrimination of the discriminating means at the selected occasion, The conversion means includes control means for controlling so that the words belonging to the field discriminated by the discrimination means as the conversion candidates are preferentially output.

[0012]

According to the present invention, since the stored information in which the notation and the field are associated with each other is used to determine the field, a large number of words can be registered as such information, and the effect of automatically discriminating the field can be immediately realized. And you can get more.

[0013] Further, when the optimum conversion field is automatically discriminated according to the usage situation of the operator, and with respect to the automatically determined conversion field, conversion means is executed by giving priority to conversion candidates. Since you can choose the time,
Depending on the situation, it is possible to present more optimal conversion candidates in the field.

According to the cursor key input, the changing process is performed, and the process proceeds to step S13-2.

In step S13-4, a process of editing the selected character string in the text buffer TEXT is performed.

In step S13-5, the selected character string is edited on the display.

At step S13-6, the notation of the selected kana-kanji conversion candidate word and the field dictionary BUNYAD
Processing is performed to search for data that matches the written information of the IC.

In step S13-7, step S13 is executed.
In -6, it is determined whether or not there is matching data. If there is data, the process proceeds to step S13-8, and if not, the process proceeds to step S13-9.

In step S13-8, step S13 is executed.
In -6, the field information of the field dictionary that matches is stored in the converted field status information BUNYASTA.

In step S13-9, it is determined whether or not there is an undetermined phrase. If not, the process ends, and if there is, the process proceeds to step S13-1.

The present invention is applicable not only to a single device but also to a system composed of a plurality of devices.
It is needless to say that the present invention can be applied not only to a device dedicated to character processing but also to a device or system having a function of outputting a character string mixed with kanji and kana by kana-kanji conversion. Further, it goes without saying that it can be realized by providing software to the device or system.

[Second Embodiment] In the above description, the timing for determining (reflecting) the field is designated, for example, at the "start of kana-kanji conversion operation", and the designated timing, kana-kanji conversion operation start At the same time, the procedure for automatically determining the conversion field and prioritizing the conversion candidates related to the determined conversion field has been described.

Similarly, it is possible to eliminate the process of designating the timing for determining (reflecting) the field, and always set this timing as "at the start of kana-kanji conversion operation".

In this case, the field determination timing selection process between steps S9-4 and S9-8 in FIG. 9 is eliminated, and steps S10-2 to S1 in FIG.
It is realized by eliminating the branching process according to the field determination timing between 0-6 and performing the process of FIG.

A flow chart summarizing the above is shown in FIG. Since the processing of each step is the same as that described in the above embodiment, the description thereof will be omitted.

As described above, according to this embodiment,
Regardless of the number of homophones of words for automatically determining the conversion field, with or without, you can register a large number of important keyword words for automatically determining the conversion field, depending on the field in which the document is created, It becomes possible to immediately convert the hiragana reading string into the priority order of the predetermined character string, and the character string that is desired to be converted can be presented immediately as a candidate.

As described above, the effect of automatically discriminating the field can be obtained immediately and extremely.

As described above, it is possible to realize a character processing device having a very high kana-kanji conversion rate depending on the field.

[Third Embodiment] In the above description, the timing for determining (reflecting) the field automatically determined by the kana-kanji conversion is selected, and the conversion field is automatically determined and automatically determined at the selected timing. It has been explained that the conversion candidates related to the conversion field can be output with priority.

Similarly, at the timing of determining (reflecting) the field automatically determined by the kana-kanji conversion, "the field automatically determined by the kana-kanji conversion is not used (field processing O
FF) ”can be added.

At this time, step S10-4 in FIG.
To the branch destination of no of No., a process for discriminating "whether the field determination timing information is the Kana-Kanji conversion end mode" is added, and if no, "process for outputting candidates in the order in which no field processing is performed" is added, and after that This is achieved by not performing field processing.

A flowchart summarizing the above is shown in FIG. Steps S15-1 to 5 and 15-7 correspond to steps S10-1 to 6 of FIG. 10, and step S15-6.
Is the above-mentioned additional determination processing, and step S15-8 is the above-mentioned "processing for outputting candidates in the order in which field processing is not performed". Steps S15-9 and below are steps S1
The specific processing of 5-8 is shown. This part is shown in Figure 11.
Since it is the same as step S11-6 and subsequent steps, the description thereof will be omitted.

As described above, according to this embodiment,
Regardless of the number of homophones of words for automatically determining the conversion field, with or without, you can register a large number of important keyword words for automatically determining the conversion field, depending on the field in which the document is created, It becomes possible to immediately convert the hiragana reading string into the priority order of the predetermined character string, and the character string that is desired to be converted can be presented immediately as a candidate.

As described above, the effect of automatically discriminating the field can be obtained immediately and greatly.

In addition, when the optimum conversion field is automatically discriminated according to the usage situation of the operator, and with respect to the automatically determined conversion field, the conversion candidate is preferentially converted. You can choose the time.

From the above, depending on the usage status of the operator,
It is possible to present conversion candidates in a more optimal field.

As described above, it is possible to realize a character processing device which has a high operability and a very high kana-kanji conversion rate depending on the field and the usage situation.

According to the present invention, whether or not there are many homophones of words for automatically determining the conversion field,
It is possible to register a large number of important keyword words for automatically discriminating the conversion field, and it is possible to immediately convert the hiragana reading string to the priority order of a predetermined character string according to the field in which the document is created. The character string you want to do can be presented immediately as a candidate.

Further, this makes it possible to immediately obtain the effect of automatically discriminating the field.

As described above, it is possible to realize a character processing method and apparatus having a very high kana-kanji conversion rate depending on the field.
