Abstract

PURPOSE:To efficiently input an intended word by replacing a KANA (Japanese syllabary) character of the same sound and a different character in an inputted KANA character-string with a different character and converting its replaced character-string to a character-string in which a KANJI (Chinese character) is mixed. CONSTITUTION:Information inputted from an input device 1 is discriminated by a next process discriminating circuit 40, and if it is character data, it is stored in a reading character-string store area 42, and if it is a conversion request, a converting instruction is outputted to a KANA (Japanese syllabary) to KANJI converting circuit 46. The KANA to KANJI converting circuit 46 fetches a reading character-string of the present time point from the reading character store area 42 by allowing it pass through a character-string changing circuit 44 without stopping, and retrieves a word dictionary store part 47. When the word concerned is not found out, a reading character-string analyzing circuit 43 fetches the same reading character-string from the reading character-string store area 42, and investigates a same sound different character stored in a same sound different character information store area 45. Subsequently, the reading character-string changing circuit 44 changes the character-string, and the KANA to KANJI converting circuit 46 executes a KANA to KANJI conversion processing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to various character processing devices such as word processors, and particularly to the kana-kanji conversion function thereof.

[Conventional technology]

Japanese characters for word processors, personal computers, etc. 8! Devices with this function (these are referred to as character processing devices) are generally equipped with an input device, a display device, and a kana-kanji conversion means, display a kana character string input from the input device on the display device, and convert it into kana-kanji. Depending on the method, it is possible to convert it into a string containing kanji.

In that case, the kana characters would be ``zu'' and ``zu'', for example.

[There are cases where the pronunciation is almost the same (homophone) but the letters are different (different letters), such as ``J'', ``ji'', ``o'', ``u'', and ``-'', but the conventional column in Figure 8 " is shown in the reading column marked with 0
If I didn't enter the ``yomi'' using the correct kana, such as ``yomi'', it would not be possible to convert it into the intended word mixed with kanji shown in the notation field.

For example, in order to convert ``continue'', you had to enter ``continue'', and if you entered ``tsuzuku'', it could not be converted.

Also, in order to be able to convert r touri J or ``dori'' like ``r-dori-no'', it was necessary to store the word ``r-dori'' in the dictionary, corresponding to each ``yomi''. .

[Problem to be solved by the invention]

Therefore, with conventional character processing devices, it is not possible to input the intended word containing kanji unless the user knows the exact kana usage of homophones, and furthermore, the kana usage changes with the times, which is inconvenient.

Therefore, we decided to make it possible to convert words with kanji mixed in as shown in the 1 notation column even if input in the ``yomi'' (reading), which could not be converted in the past, as shown in the reading column marked with an X in the conventional column in Figure 8. Then, it is necessary to add all the relationships between "yomi" and "notation" to the word dictionary, and to correspond to all of these "yomi" with slightly different usages, it would require tens or hundreds of thousands of words. , and the memory capacity must be significantly increased, resulting in an increase in cost.

This invention was made in view of the above points, and it allows users to efficiently input the intended word without knowing the exact kana usage of homonyms, as well as to make it possible to input the intended word efficiently without knowing the exact kana usage of homophones. The purpose of the present invention is to make it possible to respond flexibly to the word dictionary, and to realize this without increasing the memory capacity of the word dictionary.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a character processing device as described above, which includes a homophone and allograph storage means for storing a plurality of groups of homophones and allographs, and a homophone and allograph storage means for storing a plurality of groups of homophones and allographs in a kana character string inputted from an input device. A determining means for determining whether or not a character included in a group stored in the storage means exists, and a character replacing means for replacing the character with a different character within the same group when it is determined by the determining means that the character exists. The character string replaced by the character replacement means can be converted into a character string containing kanji by the kana-kanji conversion means.

[For production]

In the character processing device according to the present invention, if there is a character included in the kana group of homophones and allographs stored in the homophone and allograph storage means in the kana character string inputted from the input device, the first discriminating means identifies the character. As a result, the character replacement means replaces the character with a different character in the same group stored in the homophone and allograph storage means, and the replaced character string is converted into a character string containing kanji by the kana-kanji conversion means. Therefore, by simply adding a simple table as a homophone and allograph storage means, it is possible to perform kana-kanji conversion processing for input of various r-yomi of homophones and allographs without increasing the storage capacity of the word dictionary.

FIG. 1 is a block diagram showing the functions of the control unit 20 according to the present invention, in which, in addition to the input device 1 and the display device 2, the next process determination circuit 401, character string input control circuit 41. Reading character string storage area 42. Reading character string analysis circuit 43. Reading character string changing circuit 44゜Homophone and allograph information storage area 45. Kana-kanji conversion circuit 46, word dictionary storage section 472 display data creation circuit 48. and a character pattern storage section 49.

In addition, the part shown surrounded by a broken line in FIG. 1 is a part added to carry out the present invention.

Homophone and allograph information storage area 45 stores a plurality of homophone and allograph kana groups; character string analysis circuit 4;
3 is a determining means for determining whether or not a character included in the above-mentioned kana group exists in the kana character string inputted from the input device, when the reading character string changing circuit 44 determines that it exists based on the determination result. Each corresponds to a character replacement means that replaces the character with a different character within the same group.

Next, the functions of each of these parts will be explained.

The next process determination circuit 40 determines what to do next based on the input data from the input device 1 and the status of the device, and provides necessary information to the corresponding circuit.

The character string input control circuit 41 controls the input operation of the character string of the character data input from the primary process determination circuit 40.

The reading character string storage area 42 is a character string input control circuit 41
Takes the read character string and stores it. and,
This reading information is output to the reading character string analysis circuit 43 and the reading character string changing circuit 44.

The reading character string analysis circuit 43 uses the reading character string storage area 42.
It is checked whether or not there are homophonic kana characters in the input character string.

If a corresponding kana is found in the pronunciation character string analysis circuit 43, the pronunciation character string changing circuit 44 replaces the kana in the pronunciation character string with a homophone and alloji character based on the information in the homophone and allograph information storage area 45.

The homophone and allograph information storage area 45 stores a table of homophone and allograph information as shown in FIG.

When a conversion request is received from the next step discriminating circuit 40, the kana-kanji conversion circuit 46 reads the corresponding word information from the word dictionary storage section 47 and converts the kana character string into a character string containing kanji.

As shown in FIG. 6, the word dictionary storage section 47 holds information such as the reading, 9 notation, 9 parts of speech, and frequency of each word.

The display data creation circuit 48 creates pattern data for displaying characters and lines.

The character pattern storage section 49 holds character pattern data as a character generator.

Next, the operation of this embodiment configured as described above will be explained with reference to FIGS. 5 to 8.

As shown in the flow chart in FIG.
If it is character data, the character string input control circuit 41 stores it in the reading character string storage area 42 as a reading character string, and if it is a conversion request, it issues a conversion command to the kana-kanji conversion circuit 46.

As a result, the kana-kanji conversion circuit 46 reads the current reading character string from the reading character string storage area 42 and takes it out without passing through the character string changing circuit 44. If there is no reading character string, it waits for the next key input, and if there is a kana-kanji character string, it waits for the next key input. Perform conversion processing.

That is, the word dictionary storage unit 47 is searched based on the extracted reading character string, and if there is a corresponding word (candidate), 1 is searched.
The display data creation circuit 48 creates display data for the candidate character string and displays it on the display device 2.

If the corresponding word (candidate) is not found, the character string is checked for homonyms.

That is, the kana-kanji conversion circuit 46 sends a reading change request to the reading character string changing circuit 44, and the reading character string analysis circuit 4
3 takes out the same reading character string from the reading character string storage area 42 and investigates each group of homophones and allographs in the table shown in FIG. 4 stored in the homophone and allograph information storage area 45 for each character of the string. do.

Then, if there is a homophone and allograph, the reading character string changing circuit 44 changes the character string based on the homophone and allograph information, and the kana-kanji conversion circuit 47 again performs the kana-kanji conversion process on the changed reading character string. Repeat the process.

As a result of investigating homophones and different characters, if there are no homophones or different characters, the analysis result is notified to the reading character string changing circuit 44, and the character string changing circuit 44 returns the reading character string to the kana-kanji converting circuit 46 without changing the reading character string, and displays the data. The creation circuit 48 creates data for displaying the reading character string and displays it on the display device 2.

Here, as an example of homophone-kana-kanji conversion, a case will be described in which "ote" is input and converted to "ote".

The input reading data of "Oute" is sent from the reading character string storage area 42 to the kana-kanji conversion circuit 46 via the reading character string changing circuit 44.

The kana-kanji conversion circuit 4B searches the word dictionary shown in FIG. 6 in the word dictionary storage section 47, finds and extracts candidates such as "Oute" and "Oite j," and displays them on the display device 2 one after another.

Then, when there are no more candidates corresponding to the pronunciation "Oute", the kana-kanji conversion circuit 46 issues a pronunciation change request to the pronunciation character string change circuit 44. Therefore, the pronunciation character string analysis circuit 43 extracts the pronunciation data of "Oute" from the pronunciation character string storage area 42, and creates the homophone and allograph table shown in FIG. To investigate the.

In the case of "Oute", there are homophones for "O" and "U", so that information is sent to the reading character string changing circuit 44, which then uses the following character string change pattern as the character string change pattern. Create five items in order of priority.

1. Ote 2. 3. Uote 4, Uote
5. Then, in response to the request from the Kana-Kanji conversion circuit 4th, it outputs character strings that have been changed sequentially in the order of the patterns with the highest priority.

Note that since the long sound "-" is never at the beginning of a pronunciation, there is no example of a change such as "r-ute".

Therefore, first, "Ote" is the kana-kanji conversion circuit 46.
sent to. Thereby, the kana-kanji conversion circuit 46 searches the word dictionary storage section 47, finds ``mae'' as a conversion candidate, and displays it on the display device 2.

Conversely, it is also possible to input "Ote" and convert it to "Ote". In this case, it is more efficient to input "Ote" using two types of character keys than to input "Ote" using three types of character keys.

Furthermore, in the case of Roman alphabet input, "ji" is entered as rdiJ, but most systems allow "ji" to be entered as both "ji" or "rz i". therefore,
In order to output "nosebleed" as a conversion result, conventionally rh
It didn't work unless you entered anadiJ, but in this example, the last "rji" is either rdiJ or "ji" or rzi
”, the user can select the character key that he or she is most familiar with and that is easy to input.

Also, for words that are used in kana, such as ``chi'' in ``earthquake,'' where it becomes ``chi'' when it is not muddy and ``ji'' when it is murky, ``ji'' is also used with ``ji'' or [di]. Since it can be converted, incorrect input due to mistakes in using kana will be eliminated and input efficiency will be improved.

〔Effect of the invention〕

As explained above, according to the present invention, by simply adding a simple table as shown in FIG. 4 without increasing the capacity of the word dictionary, various kana usages as shown in FIG. Since it is possible to convert the information into the same "notation", input efficiency can be significantly improved, and there is almost no increase in cost.

Furthermore, even if the kana usage changes with the passage of time, it can be adapted to these changes.
