2. Description of the Related Art In a conventional kana-kanji conversion device, header information including the owner name of a dictionary is searched to check whether the dictionary is owned by a user who performs kana-kanji conversion. Was.

[0003]

However, in the conventional kana-kanji conversion device, if the character string registered in the dictionary is incorrect for some reason, a strange conversion result is obtained. Since there is no means to determine whether the dictionary format and the size of the dictionary are correct, if the configuration of the dictionary is broken for any reason, it is not possible to determine whether the dictionary can be used. There was a problem that it was not possible.

The present invention solves such a conventional problem, and uses a means for determining whether or not a dictionary used in a kana-kanji conversion apparatus is broken to determine whether or not the dictionary can be used. It is intended to provide a device.

[0005]

In order to achieve the above object, the present invention provides an input unit for inputting a character string, and outputs an input character string and a result obtained by converting the input character string into a character string mixed with kana-kanji characters. Output unit, a kana-kanji conversion processing unit that converts the input character string to a character string containing kana-kanji characters, a dictionary used for kana-kanji conversion, a dictionary management unit that manages a dictionary used for kana-kanji conversion, and a kana-kanji conversion It has a configuration including a dictionary check unit that checks a dictionary format, a dictionary size, and a character string registered in the dictionary.

[0006]

According to the kana-kanji conversion device of the present invention, a kana-kanji conversion processing unit activates a dictionary management unit for a read character string input from an input unit to obtain a Japanese sentence, and the kana-kanji conversion unit uses the dictionary management unit for conversion. The dictionary to be read is read and the dictionary check unit is started. The dictionary check unit checks the dictionary format of the read dictionary, the size of the dictionary, and the character strings registered in the dictionary, and returns whether or not the dictionary is broken to the kana-kanji conversion processing unit through the dictionary management unit. The Kana-Kanji conversion processing unit outputs an error message to the output unit if the dictionary is broken, and if it is not broken, performs Kana-Kanji conversion and outputs the conversion result to the output unit, and the dictionary can be used. It is determined whether or not.

A dictionary management unit 104 manages a dictionary used for kana-kanji conversion. 10
Reference numeral 5 denotes a dictionary check unit that checks a dictionary used in kana-kanji conversion. Reference numeral 106 denotes a dictionary used for kana-kanji conversion. FIG. 2 is a schematic diagram of a dictionary format used in kana-kanji conversion according to one embodiment of the present invention. In the figure, 2
Reference numeral 01 denotes a header information section in which the size of the entire dictionary expressed by the number of bytes, the size of the header information section 201, and the size of the main body section 202 described later are registered. Reference numeral 202 denotes a main body in which a reading character string represented by a kana character of a word and a character string mixed with kana-kanji characters represented by a JIS code character string are registered as a pair.

Actually, in addition to the above, various components are required in order to realize the function of instructing the conversion by the operator, but they are not the main object of the present invention, and therefore will be omitted.

The operation of the kana-kanji conversion apparatus of the present embodiment configured as described above will be described below. (1) The operator inputs a reading character string from the input unit 101 to obtain a Japanese sentence. (2) In response to the operation, the kana-kanji conversion processing unit 103 activates the dictionary management unit 104 to search the dictionary. (3) The dictionary management unit 104 reads the dictionary 106 to be used and activates the dictionary check unit 105. (4) The dictionary check unit 105 reads the dictionary 106
The format of the dictionary, the size of the dictionary, and the character strings registered in the dictionary are checked, and the dictionary 106
Is returned to the kana-kanji conversion processing unit 103 through the dictionary management unit 104 as to whether or not is broken. (5) Finally, the kana-kanji conversion processing unit 103 outputs an error message to the output unit 102 when the read dictionary 106 is broken, and performs kana-kanji conversion when it is not broken, Is output to the output unit 102.

The specific operation of the kana-kanji conversion device of the present embodiment, which operates as described above, will now be described. (6) Now, in order to obtain the word “finance”, the input unit 101 inputs the reading “Kinyu”. (7) The kana-kanji conversion processing unit 103 activates the dictionary management unit 104 to search for the reading “Kinyu”. (8) The dictionary management unit 104 first reads the dictionary 106 having the format shown in FIG. 2 and activates the dictionary check unit 105. (9) The dictionary check unit 105 reads the dictionary 106
First, in order to determine whether the format of the dictionary is composed of the header information section and the main body section,
6 of the header information section 201, the size of the dictionary 106, the size of the header information section 201, and the main body section 202.
It is determined whether or not the size is registered as a number.
As a result, when the entire size of the dictionary 106, the size of the header information section 201, and the size of the main body section 202 are registered by numbers, the entire size and header information are stored in the header information section of the read dictionary 106. If the size of the unit 201 and the size of the main unit 202 are correctly registered, it is determined that the entire size of the dictionary 106, the size of the header information unit 201, and the size of the main unit 202 are not registered by numbers. The kana-kanji conversion processing unit 10 is notified through the dictionary management unit 104 that the read dictionary 106 is broken.
Return to 3. (10) Further, the dictionary check unit 105 extracts the number of bytes of the entire size of the read dictionary 106 to determine whether the size of the read dictionary 106 is correct, and registers the number of bytes in the header information unit 201. It is determined whether or not the number of bytes of the entire dictionary 106 matches the number of bytes.
As a result, when the entire size of the dictionary 106 matches the number of bytes of the entire size of the dictionary 106 registered in the header information unit 201, the read dictionary 106
Is not broken, it is determined that the read dictionary 106 is broken when the entire size of the dictionary 106 does not match the number of bytes of the whole size of the dictionary 106 registered in the header information section 201. Is returned to the kana-kanji conversion processing unit 103 through the dictionary management unit 104. (11) Next, the size of the main body 202 of the dictionary 106 is calculated in bytes from the size of the entire dictionary registered in the header information section 201 of the dictionary 106 and the size of the dictionary of the header information section. I do. Then, it is determined whether or not the calculated size of the main body 202 of the dictionary 106 matches the size of the main body of the dictionary 106 registered in the header information unit 201. As a result, the calculated number of bytes of the size of the main body 202 of the dictionary 106 and the dictionary 106
If the number of bytes of the size of the main unit 202 registered in the header information unit 201 of the same matches, it is determined that the dictionary 106 is composed of the header information unit and the main unit of the calculated dictionary 106. If the number of bytes of the size of the main unit 202 does not match the number of bytes of the size of the main unit 202 registered in the header information unit 201 of the dictionary 106, it is determined that the read dictionary 106 is broken. Management unit 1
04 to the kana-kanji conversion processing unit 103. (12) Finally, the dictionary check unit 105 determines whether the character string registered in the read dictionary 106 is composed of a character string mixed with a read character string and a kana-kanji character. It is determined whether or not the reading character string registered in 202 is a kana character. And
As a result, when the reading character string registered in the main body 202 of the dictionary 106 is a kana character, it is determined that the reading character string registered in the main body 202 of the dictionary 106 is a kana character. If the read character string registered in the main unit 202 is not a kana character, the read dictionary 10
6 is returned to the kana-kanji conversion processing unit 103 through the dictionary management unit 104. (13) Then, the dictionary check unit 105 sets the dictionary 106
It is determined whether or not the character string containing kana-kanji characters registered in the main body 202 is a JIS code character string. As a result, if the character string containing Kana-Kanji characters registered in the main body 202 of the dictionary 106 is a JIS code character string, the character string containing Kana-Kanji characters registered in the main body 202 of the dictionary 106 is converted into a JIS code. If the character string containing kana-kanji characters registered in the main body 202 of the dictionary 106 is not a JIS code character string, it is determined that the read dictionary 106 is broken. Return to the processing unit 103. (14) If the message from the dictionary check unit 105 indicates that the read dictionary 106 is broken, the kana-kanji conversion processing unit 103 outputs an error message to the output unit 102, and outputs the error message to the dictionary check unit If all of the messages from 105 do not indicate that the read dictionary 106 is broken, Kana-Kanji conversion is performed and the conversion result “finance” is output to the output unit 102.

In the present embodiment, the size of the entire dictionary expressed in terms of the number of bytes, the size of the header information portion, and the size of the main body portion are registered in the header information portion. A description has been given of the dictionary check means of a format composed of a main part in which a reading character string and a character string mixed with kana-kanji written in a JIS code character string are registered as a pair. However, it goes without saying that a dictionary for checking the same items in a dictionary having another format is included.

[0013]

As described above, the kana-kanji conversion apparatus of the present invention checks the dictionary format, the size of the dictionary, and the character strings registered in the dictionary, in addition to the check of the dictionary owner which has been checked conventionally. Since the dictionary check unit is used, it is determined whether the dictionary used in Kana-Kanji conversion is not broken by using the means to determine whether the dictionary is usable. It is possible to prevent the wrong output of the conversion result and the runaway of the Kana-Kanji conversion process due to the presence of the key, which is extremely advantageous in practical use.
