Abstract

A word converting apparatus displays converted results and cooccurrent examples in a candidate selection menu for allowing the user to easily and definitely select converted results of words in a cooccurrent relationship. A cooccurrence recognizer 15 recognizes a cooccurrent relationship between words using a cooccurrence dictionary 13. A converter 16 refers to a general dictionary 12 and the cooccurrence dictionary 13 to store a converted result corresponding to a word in a result storage unit 17. If a converted result is derived from the general dictionary 12, a candidate storage unit 18 stores the converted result. If a converted result is derived from the cooccurrence dictionary 13, the candidate storage unit 18 searches the cooccurrence dictionary 13 for a cooccurrent example and stores the cooccurrent example. When candidate selection is indicated, a candidate selector 19 displays converted results and cooccurrent examples stored in the candidate storage unit 18, in a candidate selection menu on a display unit 20. When a candidate alternative is selected from the candidate selection menu, the candidate selector 19 instructs the converter 16 to give highest priority to a selected converted result or a converted result corresponding to a selected cooccurrent example, and the converter 16 changes a converted result in the result storage unit 17.

Claims

1. A word converting apparatus comprising:

an input unit for entering a string of characters;

a general dictionary for holding converted results and converted-result IDs with respect to entries;

a cooccurrence dictionary for holding converted results, cooccurrent examples, and converted-result IDs with respect to each of the words in a combination of cooccurrent words;

a word recognizer for dividing a string of characters entered by said input unit into a string of words by referring to said general dictionary;

a cooccurrence recognizer for recognizing cooccurrent relationships between the words divided by said word recognizer, by using said cooccurrence dictionary;

a result storage unit for storing converted results and converted-result IDs with respect to each of the words divided by said word recognizer, in order of priority;

a candidate storage unit for storing a converted result stored in said result storage unit so as to correspond to a word if the converted result stored in said result storage unit is derived from said general dictionary, and searching said cooccurrence dictionary for a cooccurrent example and storing the cooccurrent example so as to correspond to a word if the converted result stored in said result storage unit is derived from said cooccurrence dictionary;

a converter for storing converted results corresponding to the words divided by said word recognizer, in said result storage unit by referring to said general dictionary, and, if a cooccurrent relationship is recognized between the words by said cooccurrence recognizer, storing a corresponding combination of converted results and converted-result IDs in said result storage unit by referring to said cooccurrence dictionary, and replacing the converted results in said result storage unit according to the order of priority;

a display unit for displaying the converted results in said result storage unit; and

a candidate selector for displaying the converted results and cooccurrent examples stored in said result storage unit, in a candidate selection menu on said display unit when the words are indicated and candidate selection is indicated, and, if a candidate alternative in said candidate selection menu is selected, instructing said converter to give highest priority to a selected converted result or a converted result corresponding to a selected cooccurrent example, using a converted-result ID as a key.

2. A word converting apparatus according to claim 1, wherein said candidate selector highlights a word for which candidate selection is indicated, in the converted results displayed on said display unit, and simultaneously highlights the candidate alternative selected in said candidate selection menu.

3. A word converting apparatus according to claim 1, wherein the converted-result IDs in said general dictionary and the converted-result IDs in said cooccurrence dictionary are distinguishable from each other, and wherein said candidate selector decides whether a converted result is derived from said general dictionary or said cooccurrence dictionary based on a converted-result ID.

4. A word converting apparatus according to claim 1, wherein when a converted result of highest priority in said result storage unit is changed, said converter shifts a converted result previously stored in said result storage unit to lower priority, and adjusts the cooccurrent relationship of the converted result previously stored in said result storage unit if the converted result previously stored in said result storage unit is derived from said cooccurrence dictionary.

5. A word converting apparatus according to claim 4, wherein said converter adjusts the cooccurrent relationship of a converted result by giving highest priority to converted results having the same converted-result ID with respect to a word which has not been adjusted for a cooccurrent relationship, shifting a converted result previously stored in said result storage unit to lower priority, and further adjusting the cooccurrent relationship of the converted result previously stored in said result storage unit if the converted result previously stored in said result storage unit is derived from said cooccurrence dictionary.
