Abstract

PURPOSE:To execute KANA (Japanese syllabary)-KANJI (Chinese character) conversion at a high speed by retrieving the stored contents of a dictionary to correspond to a specified filed to be designated and executing the KANA- KANJI conversion from inputted character information to a desired character string when there is no homonym to correspond to the inputted character information in the stored contents of a basic vocabulary KANJI dictionary. CONSTITUTION:When the KANA-KANJI conversion is executed from the inputted character information to the desired character string, the storing contents of a basic vocabulary KANJI dictionary 15C are retrieved at first. When there is no homonym to correspond to the inputted character information in the stored contents of this basic vocabulary KANJI dictionary 15C, the stored contents of dictionaries 15A (technique) and 15B (commerce), which are correspond to the specified field to be designated, are retrieved and the KANA- KANJI conversion is executed from the inputted character information to the desired character string. Thus, by designating the field of a document to be prepared by an operator, a processing speed can be improved in the case of the KANA-KANJI conversion and efficient document preparation can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a kana-kanji conversion device that converts character information input in kana or Roman characters into a character string containing a mixture of kana and kanji.

[Conventional technology]

Conventional kana-kanji conversion devices generally store a kana-kanji conversion dictionary in ROM and search this kana-kanji conversion dictionary to improve the processing speed when converting kana-to-kanji. There is.

However, if a large-capacity kana-kanji conversion dictionary is stored in ROM, most of the main memory will be occupied by the dictionary, which will reduce the speed of other processes such as document editing. Since the character string containing kana and kanji that corresponds to the information must be searched from the above-mentioned large-capacity kana and kanji conversion dictionary, the search time becomes long.

For this reason, it would be better to reduce the number of words and store a small-capacity kana-kanji conversion dictionary consisting only of "basic words" in ROM, but in this case, compound words and technical terms would not be registered in the dictionary. Therefore, when converting input character image information into a string containing kana and kanji, the kanji must be separated and converted several times, which takes extra time and effort. There is.

Therefore, the invention disclosed in JP-A-61-180360 has a plurality of dictionaries, outputs and displays the types of each of these dictionaries, and selects an instruction from among the displayed dictionary types by the operator. I am trying to access a specific dictionary.

[Problem to be solved by the invention]

By the way, in the invention disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 61-180360, an operator who is not familiar with the contents of dictionaries cannot know which dictionary to select from a plurality of dictionaries to perform kana-kanji conversion most efficiently. There are drawbacks.

It is an object of the present invention to provide a kana-kanji conversion device that can speed up the processing speed of kana-kanji conversion and efficiently create documents by specifying the field of the document created by an operator.

[Means and effects for solving the problem] The present invention provides information on documents divided according to predetermined classifications in a plurality of fields (general, general, etc.).
a first kanji storage means (basic word kanji dictionary) for storing a plurality of kanji common to each of the above-mentioned fields; A plurality of second kanji storage means (kanji dictionary) that stores a plurality of kanji corresponding to the field, and when the specific field is specified, the storage contents of the first kanji storage means and the specific kanji are stored. Search the storage contents of a specific second kanji storage means corresponding to the field and convert the input character information into a desired character string in kana according to the storage contents of the first kanji storage means or the second kanji storage means. comprising a kana-kanji conversion means for converting kanji,
When converting input character information into a desired character string, the stored contents of the basic word kanji dictionary are searched first, and the input character information is found in the stored contents of the basic word kanji dictionary. If there is no corresponding homophone, the stored contents of the dictionary corresponding to the specified specific field are searched and the input character information is converted into a desired character string in kana-kanji.

〔Example〕

Embodiments of the kana-kanji conversion device according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of a kana-kanji conversion device according to the present invention. In the figure, the keyboard 11
A mouse 12 connected to the keyboard 11 is used to input various data, commands, etc.

External memory bag! (Disk device) 13 stores data (documents) and programs to be edited.

The dictionary ROM 14 stores a basic vocabulary dictionary for kana-kanji conversion. The auxiliary storage unit 15 stores dictionaries for kana-kanji conversion in fields related to documents to be created, such as "general", "technical", "official documents", "commercial", etc. In the embodiment, the auxiliary storage unit 15 includes a technical term dictionary (technical) 15A and a technical term dictionary (commercial).
15B and a proper noun dictionary 15C.

Note that each dictionary group may have information regarding the classification of each dictionary group, or a separate file corresponding to each dictionary group may have information describing the composition of that dictionary group. The 0 character information storage section 16 is made up of a RAM and temporarily stores data, calculation results, etc. Font ROM
17 has multiple types of character fonts. The dictionary switching unit 18 selects one or more dictionaries corresponding to the designated specific document field from among the dictionaries stored in the auxiliary storage unit 15. The homophones corresponding to the written character information are searched for in each of the above dictionaries and converted into the corresponding kanji. Control unit (CPU) 2
0 is, for example, a keyboard 1 that executes predetermined calculations, processing, etc. according to a program corresponding to the input command.
1 (or the mouse 12), the dictionary switching unit 18 is instructed to select a specific dictionary. Further, an instruction is given to the character conversion unit 19 to search for a kanji character corresponding to the character information input by operating the keyboard 11 from the basic word dictionary or a dictionary selected from the auxiliary storage unit 15 and convert it into the corresponding kanji character. The CPU 20 also reads character dots corresponding to the data from the font ROM 17 and controls the CRT drive circuit 21 to display the character dots on the CRT 22 for display.

Next, the operation of the kana-kanji conversion apparatus for converting kana-to-kanji will be explained based on the flowchart shown in FIG.

The operator uses the keyboard 11 (or mouse 12)
The operation causes the CRT 22 to display an initial menu for selecting the type (field) of the document to be created, and further selects the type (field) of the desired document (step 100).
), this initial menu includes the types (fields) of the document to be created, ie, fields such as ``General'', ``Technical'', ``Official Documents J'', and ``Commercial''. When a specific field is selected from among these fields, the CPU 20 instructs the dictionary switching unit 18 to select one of the dictionaries stored in the auxiliary storage unit 15.
For example, select a dictionary corresponding to the selected field.
When the field of "technology" is selected by the operator, the dictionary switching unit 18 selects the technical term dictionary (technology) 15A corresponding to the field of "technology" (step 101). Terminology dictionary (technology) 15
A is set, and each of these dictionaries can be searched. Note that if none of the above fields is selected, "general" is selected by default, and only the general dictionary, that is, the basic vocabulary dictionary is searched. This basic word dictionary has registered kanji that are common to the field of the document (step 102). Here, in the basic word dictionary, there are kanji that correspond to the character information "chosa". "investigation"
It is also assumed that the technical term dictionary 15A includes the kanji character ``conductivity'' corresponding to the character information ``dodensei''.

Next, the operator inputs predetermined character information, for example, "How to choose" (step 10).
3), when the kanji conversion key is further pressed (step 1
04), the CPU 20 instructs the character conversion unit 19 to search the dictionary for a Kanji character corresponding to the character information and convert it into the corresponding Kanji character.

The character conversion unit 19 extracts the phrase "Dodensei wo" from the input character information based on the instructions from the CPU 20, and also extracts the independent word "Dodensei" from the extracted phrase (step 105), and the character conversion unit 19 first searches the basic word dictionary.
Step 106) Determine whether or not a homophone corresponding to "Dodensei" is stored in this basic word dictionary (Step 107) The converting unit 19 determines whether a dictionary corresponding to a specific field (type field) of the document to be created has been set (step 108), and if no dictionary has been set, the process returns to step 105. , performs clause extraction and analysis processing of character information again, and conversely, if a dictionary corresponding to a specific field is set, searches for the set dictionary from the auxiliary storage unit 1515 (step 109), determine whether there is a homophone in the searched dictionary (step 110);
For example, if there is no homophone corresponding to the above-mentioned "Dodensei J" in the basic word dictionary, the character conversion unit 19 searches the technical term dictionary 15A and searches the technical term dictionary 15A.
It is determined whether there is a homophone corresponding to "dodensei" in A. If there are no homophones here, the process returns to step 105, and the clause extraction and analysis processing of the text information is performed again. If there are homophones, "All homophones corresponding to (Step 1)
11).

Note that, if there is a homophone in step 107, that is, if there is a homophone corresponding to the character information in the basic word dictionary, the character conversion unit 19 converts the phrase "" from the character information, for example.
If "chosa" is extracted, and if there is a homophone corresponding to this "chosa" in the basic word dictionary, the process proceeds to step 111 and the corresponding homophone "chosa" is extracted. You will be creating a "survey."

Then, the character conversion unit 19 performs homophone processing such as checking the connection relationship of words in the kanji string corresponding to the created homophone and checking the meaning in the kanji string corresponding to the created homophone (step 112), a kanji string corresponding to the homophone determined through homophone processing, for example, “
The kanji string ``conductivity'' corresponding to Dodensei J is displayed on the CRT2.
2 (113), and then it is determined whether or not the operator has finished inputting the predetermined character information (step 114). If character information has been input, the process returns to step 105, and the process returns to step 105. Steps 105 and subsequent steps are executed, and when the input of character information is completed, all processing execution is completed.

In the above example, the fields of documents are "technical", "official documents",
Although we have made a general classification such as "commerce," it is clear that the field of documents can be further classified in detail.
It is also possible to construct dictionaries corresponding to each field.

In the above embodiment, general kanji are registered in the basic word dictionary, and kanji used in each field are registered in the dictionary corresponding to the document field, but this is not limited to this. Kanji that are commonly used and also used in each field may be registered in the basic word dictionary and the dictionary corresponding to the document field.

In the above embodiment, one dictionary is configured to correspond to a specific document field, but the invention is not limited to this, and a plurality of dictionaries may be configured to correspond to a specific document field. Good 0 For example, in the kana-kanji conversion device shown in FIG. 1, the technical term dictionaries 15A and 15B may be configured according to the field of technology. Since the small capacity kana-kanji conversion dictionary is stored in ROM,
The speed of kana-kanji conversion becomes faster when creating general documents. In addition, when an operator specifies the field of a document to be created, the dictionary corresponding to the specified field is automatically loaded into the auxiliary storage device, so the operator does not have to be aware of the presence or absence of words and the contents of the dictionary. You can create documents without having to worry about it.

〔Effect of the invention〕

As explained above, according to the present invention, when converting input character information into a desired character string in kana-kanji, the stored contents of the basic word-kanji dictionary are first searched, and the stored contents of the basic word-kanji dictionary are searched. If there is no homophone corresponding to the input character information in the memory contents, search the memory contents of the dictionary corresponding to the specified specific field and convert the input character information into the desired character string in kana-kanji. As a result, it is only necessary to search the memory contents of the basic word-kanji dictionary or the dictionary corresponding to the designated specific field, and the speed of kana-kanji conversion can be increased.

In addition, character information related to the specified field is searched from the corresponding dictionary, so the probability of it being converted into meaningless compound words, character strings, etc. is extremely low, and efficient document creation is possible. It becomes possible.
