DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a machine translation apparatus and a machine translation recording medium for translating a text in a certain language into a different language.

[0002]

2. Description of the Related Art Heretofore, there has been known a method of using a technical term dictionary prepared for each field in order to improve translation quality in machine translation. There is also known a method of creating and using a user dictionary for each field in order to deal with technical terms not registered in the technical term dictionary.

[0003]

However, in conventional machine translation, there is a problem that it is necessary to judge the field of the original sentence and switch the user dictionary.

Accordingly, the present invention is to automate the selection of a user dictionary by checking the appearance frequency of words in an original sentence for each technical term dictionary and selecting a user dictionary corresponding to the field of a technical term dictionary with a high frequency. It is an object of the present invention to provide a machine translation device and a machine translation recording medium that can perform the above.

[0005]

According to the present invention, there is provided a technical term dictionary comprising: an input unit for instructing an operation and inputting an original sentence; a technical term dictionary storage unit for storing a technical term dictionary; and a word included in the original sentence. An original sentence analysis unit that analyzes whether or not it is registered in the database, a specialized field statistical information storage unit that stores the analysis result of the original sentence analysis unit, a field-specific user dictionary storage unit that stores a user dictionary for each field, and used for translation. A field-specific user dictionary selection unit that stores a field-specific user dictionary, a translation unit that translates the original text,
It has a display unit for displaying translation results and a control unit for controlling each of them.

With this configuration, it is possible to automate the selection of the user dictionary by checking the frequency of appearance of the words in the original sentence for each technical term dictionary and selecting the user dictionary corresponding to the field of the technical term dictionary with high frequency. A machine translation device that can be provided.

A field-specific user dictionary storage unit 106 stores a field-specific user dictionary used for translation obtained from information stored in the field-specific statistical information storage unit 104, and a field-specific user dictionary selection unit 107. A field-specific user dictionary priority order allocating unit 108 for storing the priority of the field-specific user dictionary used for translation obtained from the information stored in the storage unit 104, Translation of the original sentence input from the section 101 from the technical term dictionary stored in the technical term dictionary storage section 102 or the user dictionary stored in the field-specific user dictionary storage section 105 stored in the field-specific user dictionary selection section 106 A translation unit that translates using the field-specific user dictionary to be used in accordance with the priority order stored in the field-specific user dictionary priority assignment unit 107; 109, a display unit that outputs the translation obtained from the translation unit 108; It is a control unit for controlling each of the above.

FIG. 2 is an apparatus block diagram showing a machine translation apparatus according to one embodiment of the present invention. 201 is a read only memory (ROM), 202 is a random access memory (RAM), 203 is a central processing unit (CPU),
204 is a keyboard (KEY), 205 is a display (CRT), 206 is a CD-ROM drive, and 207 is a CD-ROM.

In FIG. 1 and FIG. 2, the input unit 101 is a KE
This is realized by Y204. Technical term dictionary storage unit 102
Is realized by the ROM 201. The original analysis unit 103, the translation unit 108, and the control unit 110
01 is executed, and data is exchanged with the ROM 201 and the RAM 202. The specialized field statistical information storage unit 104, the category-specific user dictionary storage unit 105, the category-specific user dictionary selection unit 106, and the category-specific user dictionary priority assignment unit 107 are realized by the RAM 202. The display unit 109 is realized by the CRT 205.

The operation of the machine translator configured as described above will be described below. FIG. 3 is a flowchart of the operation of the machine translation apparatus according to the embodiment of the present invention.
First, a user inputs an original sentence to be translated from the input unit 101 (step 1). Next, the original sentence analysis unit 103 analyzes in which technical term dictionary stored in the technical term dictionary storage unit 102 the words included in the original sentence input from the input unit 101 are registered (step 2).

Next, the control unit 110 obtains statistical information for each technical term dictionary from the analysis result obtained in step 2 and stores the statistical information in the specialized field statistical information storage unit 104 (step 3). Next, the control unit 110 stores the specialized field statistical information storage unit 1
A field-specific user dictionary to be used for translation is determined from the statistical information in step 04 and stored in the field-specific user dictionary storage unit 105. Furthermore, the priority of the field-specific user dictionary used for translation is determined and stored in the field-specific user dictionary priority allocation unit 107 (step 4). Next, the translation unit 108 translates the original sentence input in step 1 using the user dictionary determined in step 4 with priority (step 5). Finally, the control unit 1
10 displays the translation result obtained in step 5 on the display unit 109 (step 6).

In this embodiment, the CPU 203 executes the program stored in the ROM 201. However, the program stored in the CD-ROM (recording medium) 207 is stored in a CD-ROM drive (read-out). The data may be read out via the (device) 206 and executed by the CPU 201. With such a configuration, the present invention can be easily realized by a general-purpose computer or the like. The recording medium is a CD-ROM.
(See D. Rom)
Anything that can be read by a computer, such as D (floppy disk) or DVD (digital video disk), may be used.

[0019]

As described above, according to the machine translation apparatus of the present invention, since the field-specific user dictionary is selected by using the appearance frequency information of the words included in the original sentence in each specialized field dictionary, the field-specific user dictionary is selected. Can be omitted, and forgetting to select the field-specific user dictionary can be prevented.
