Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention inputs a kana character string including the pronunciations of kanji words and their compound words, and converts it into a kanji-kana mixed sentence by referring to a built-in dictionary. This invention relates to a character processing device, and is particularly designed to efficiently convert kanji compound words by taking into consideration the existence of homophones.

[Prior Art] In this type of conventional character processing device that performs kana-kanji conversion, for example, when a kana character string such as ``kenkiyu'' is input, the device searches a built-in dictionary to find the kanji word ``research.'' Display the output. However, many Japanese kanji words have homophones; for example, the pronunciation of ``Kosei'' has ``welfare'', ``composition'', ``offensive'', and ``fairness''.
,
There are multiple kanji words with the same sound, such as "proofreading."
When inputting a kana character string that includes the pronunciation of a kanji word in which such a homophone exists, conventionally, the part where the homophone exists is displayed on the display screen to indicate to the operator that the homophone exists. The display is displayed by blinking or changing the display brightness, and other homophones are listed and displayed on a part of the display screen, and the user is asked to select the appropriate kanji word from among these homophones. It was becoming like that. On the other hand, when performing kana-kanji conversion in this type of character processing device, the input kana character string is input in each appropriate input unit length, and at the same time, the kana character string is input continuously for each input unit,
Indicates the delimiter of the input kana string, for example, Kanji delimiter key, bunsetsu delimiter key, dot ",", circle "."
Delimited data such as Generally, one word is treated as one input unit, but compound words, that is, words that are made by combining multiple kanji words, can also be input as one input unit to avoid the trouble of inputting each word separately. It is often entered all at once. On the other hand, in order to accommodate all such compound words in a dictionary, it is necessary to significantly increase the storage capacity of the storage device storing the dictionary, and the kana character string for each input unit is divided within the device and the corresponding kanji It was designed to search a dictionary for a word and output and display a combination of those kanji words.

[Problem to be solved by the invention] Conventionally, when a homophone is included in a compound word, the output display must be made to blink or change its brightness for each input unit at the same time as each word. Furthermore, when enumerating homophones, all the homophones for each input unit are listed and displayed, allowing the user to select a homophone for each input unit. Therefore, even if only one word in a long compound word consisting of multiple words has a homophone, the entire output display for one input unit including that compound word will blink or change its brightness. Therefore, it is difficult for the operator to determine which words in a compound word have homophones, making it difficult to select and proofread homophones.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks, and to determine whether a compound word in a kanji string obtained by converting a kana character Moji string input for each input unit can be determined for each word constituting the compound word. , information on whether or not a kanji word cannot be determined due to the existence of homophones is shown, and the kanji word of the conversion output that cannot be determined can be clearly distinguished from other kanji words, thereby efficiently performing kana-kanji conversion. The object of the present invention is to provide a character processing device that can obtain the desired character processing results.

[Means for Solving the Problem] In order to achieve such an object, the present invention has the following features:
an input means capable of inputting a kana character string; a display means; a storage means for storing kanji words that are candidates for kana-kanji conversion and that correspond to the pronunciations of words composed of kana characters; A kana string consisting of the pronunciations of multiple words,
instruction means for instructing conversion into a compound word consisting of a plurality of kanji words and displaying it on the display means; and decomposition for decomposing the kana character string into the readings of a plurality of words in response to instructions from the instruction means. means, conversion means for converting each of the pronunciations of a plurality of words decomposed by the decomposition means into Kanji words by the storage means, and a Kanji word converted by the conversion means is uniquely stored in the storage means; When the kanji word is a candidate for kanji conversion, the kanji word is displayed in one display format, and when the kanji word is one of the plurality of kanji conversion candidates stored in the storage means, the kanji word is displayed. and display control means for displaying in a display format different from the first display format.

[Operation] According to the present invention, the reading kana that cannot be determined due to the existence of a homophone in the reading kana group corresponding to each kanji word forming a compound word in a series of input kana character strings. Only kanji words are displayed in a manner different from other words.

[Example] The present invention will be described in detail below with reference to the drawings.

FIG. 2 shows a specific example of the keyboard 5, where 5A is a kanji key that specifies the delimiter of kanji,
The kana input data between the two delimiters inputted from the kanji key 5A is converted into kanji. 5
B is a cursor movement key, which can move the cursor in four directions (up, down, right, left, and right) as shown, thereby moving the cursor to any desired position on the CRT display device 8. 5C is a selection key, and after moving the cursor to the position of the homophone you want to select from among the homophones listed and displayed on the CRT display device 8 using the cursor movement key 5B, press the selection key 5C. Therefore, select only the corresponding homophone and display the CRT display device 8.
Only the homophones selected above are displayed, and the remaining homophones are deleted. Furthermore, when selecting any desired word from among the compound words listed and displayed on the CRT playback device 8, the cursor movement key 5B and selection key 5C are similarly used.

Next, using as an example a case where a kana character string "Kosei Daijin" is input as a kanji compound word, the process of kana-kanji conversion in the character processing device of the present invention will be explained using FIGS. 3 and 4. I will explain.

First, the input kana character string is decomposed into multiple kana character strings (step S1 in Figure 3), and the dictionary stored in the RAM 15 is searched for each decomposed kana character string (step S2). kanji words
The result is written to the output buffer memory 15A in the RAM 15 (step S3), that is, the result of decomposing the input kana character string "Kosei Daijin" into the kana character strings "Kosei" and "Daijin" and searching the dictionary. As shown in Figure 4, five kanji words were obtained for the kana string ``Kosei,'' and a single kanji word was obtained for the kana string ``Daijin.'' shall be taken as a thing. Therefore, the kanji word "Minister" which is a single conversion output for the kana string "Daijin" is determined as the conversion output, but the five homophones as conversion outputs each corresponding to the kana string "Kosei" are determined as the conversion output. Regarding the words, judgments such as grammatical processing are made (step 4), and since they all have the same part of speech, it is not possible to select a single kanji word from among the five homophones and confirm it as the conversion output, The confirmation flag is set to "0" (step S6), and the operator's judgment is requested. Incidentally, since there is no homophone for the Kanji word "Minister" corresponding to the kana character string "Daijin", the confirmation flag is set to "1" as shown in the figure (step S7).

Next, convert the converted output kanji word as described above to
When displaying on the display surface of the CRT display device 8, the microprocessor 1 uses the output buffer memory 15A.
The display control code in the refresh memory 11 is set to high-intensity display for conversion output kanji words whose confirmation flag is "1", and for words whose flag is "0". For example, change the code to display a low-brightness display (steps S8 and S9). Therefore, for example, "Minister of Health and Welfare" may be displayed on the display screen of the CRT display device 8.
A display like ``Kosei'' is displayed, and only the part of ``Kosei'' is displayed with lower brightness, for example, and there are homophones only for ``Kosei'' in the input kana string, and the The operator can be asked to select a single converted output Kanji word from among them.

[Effects of the Invention] As is clear from the above description, according to the present invention, homophones exist in the pronunciation kana group corresponding to each kanji word forming a compound word in a series of input kana character strings. By displaying only the kanji words corresponding to the pronunciations that could not be determined by using a different method, it is easier for the operator to judge the selection of homophones, thereby improving the operability of character processing. A remarkable effect can be obtained in that the performance can be significantly improved compared to the conventional method.
