Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dictionary registration method for a machine translation device. 2. Description of the Related Art A machine translator for automatically converting a first language source sentence input from a keyboard or an original file and stored in an original storage unit into a second language translation using computer technology and outputting it. Is being developed. The machine translation device basically divides an input original sentence into predetermined processing units (for example, words and phrases) by morphological analysis and syntax analysis, and finds a corresponding translation by referring to a translation dictionary for each processing unit. The translation is obtained by combining them according to a predetermined translation rule. [0003] As a translation dictionary, information of various dictionaries such as a word dictionary of a first language to a second language required for translation processing and a grammar dictionary is stored. Ideally, all of the existing words are registered in the word dictionary.However, in actuality, considering the labor required to create the dictionary and the current state of society in which new words are being created one after another. Nearly impossible. Therefore, it is inevitable that a word not registered in the word dictionary, that is, an unknown word exists in the original text to be translated. In a conventional machine translation apparatus, when an unknown word is found by morphological analysis of an original sentence during a translation process,
The operator was notified each time. The operator sees the message, inputs attribute information such as a translated word or part of speech corresponding to the unknown word, and registers it as a new word in the translation dictionary. However, if the original sentence is relatively short, it is good, but if the sentence is several tens of pages or longer, it is not possible to perform dictionary registration operation by inputting attribute information such as a translation word corresponding to the unknown word every time an unknown word is found. Extremely cumbersome and significantly reduces translation efficiency. [0005] As described above, in the conventional machine translation apparatus, when performing a dictionary registration operation, a dictionary registration operation is performed for each set of attribute information such as an unknown word and a corresponding translated word. Has to be performed one by one, so if there are many unknown words to be registered, there is a problem that the dictionary registration operation becomes extremely complicated. In addition, the efficiency of translation processing including dictionary registration has been significantly reduced. SUMMARY OF THE INVENTION The present invention has been made in consideration of the above circumstances, and has as its object to provide a dictionary registration method capable of efficiently registering unknown words in a machine translation device. According to the present invention, there is provided a translation dictionary unit of a machine translation apparatus for translating an original text to be translated using information in a translation dictionary unit containing information of various dictionaries including a word dictionary. In the dictionary registration method for registering unknown words in a dictionary, based on a list including a set of attribute information including a translated word and a word to be registered as an unknown word, each word to be registered as an unknown word in the list Are registered together in the translation dictionary unit together with the attribute information, and at that time, for the words whose part of speech is omitted from the attribute information in the list, the part of speech is registered as a noun in the dictionary. According to the present invention, first, a list of attribute information including a translation word corresponding to a word to be registered as an unknown word is created, and each word of this list is collectively stored in the translation dictionary together with the corresponding attribute information. By registering the dictionary, a large number of unknown words can be registered efficiently with a minimum input operation. [0009] For example, if unknown words in the original sentence are registered prior to translation, the machine translator can smoothly translate the original sentence, and consequently the efficiency of translation processing including dictionary registration. Is greatly improved. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a machine translation apparatus according to one embodiment of the present invention. Hereinafter, an English-Japanese translation will be described as an example. In FIG. 1, an input unit 1 composed of a keyboard is used for inputting an original sentence to be translated and inputting various commands. Are stored in the original text storage unit 3 via the editing control unit 2 which controls the entire apparatus. The original sentence stored in the original sentence storage unit 3 is translated by the translation unit 4 into a Japanese sentence that is a second language. The translation dictionary unit 5 includes various dictionaries used for translation processing in the translation unit 4, for example, (1) a utilization / change dictionary for converting a word whose ending or the like changes to its original form (basic type), (2) a first language A word / phrase dictionary in which translated words in the second language (Japanese) corresponding to words / idioms in (English) are stored together with their part-of-speech information, (3) an analytic grammar dictionary in which a correct part-of-speech sequence is stored, (4) A conversion grammar dictionary in which conversion information from English to Japanese is stored, (5) a generated grammar dictionary that determines the structure of the converted Japanese sentence, (6) by changing word types such as Japanese endings It contains a morpheme generation grammar dictionary that completes the translation sentence. The translated sentence obtained by the translation unit 4 is stored in the translated sentence storage unit 6 via the edit control unit 2. The display unit 7 is for displaying the original sentence and the translated sentence, and the printing unit 8 is for outputting the original sentence and the translated sentence as a hard copy. According to the present invention, in addition to the basic configuration of the above-described machine translation apparatus, all the unknown words in the original sentence stored in the original sentence storage unit 3, that is, the unknown words for retrieving words not contained in the translation dictionary unit 5 are retrieved. A search unit 9; an unknown word storage unit 10 for storing the words searched by the unknown word search unit 9; and a translation dictionary unit for storing the words stored in the unknown word storage unit 10 together with attribute information including the corresponding translated word. 5 is provided with a dictionary registration unit 11 for registering as a new word. FIG. 2 shows an example of the key arrangement of the input unit 1, which is provided with character keys 21, edit keys 22, function keys 23, cursor control keys 24, and other keys. The function keys 23 include keys for inputting an unknown word search request, an unknown word editing request, and a dictionary registration request. FIG. 3 shows a display example of a phrase searched for as an unknown word by the unknown word search unit 9, and FIG. 4 shows a searched unknown word and a translated word input by the operator for the unknown word. Are displayed in association with each other. Next, the procedure of searching for an unknown word, storing an unknown word, and registering a new word dictionary in this embodiment will be described with reference to the flowchart shown in FIG. The edit control unit 2 monitors the presence or absence of a key input from the input unit 1 in steps S1 to S5, and performs any processing corresponding to any key input. When the operator operates any of the function keys 23, this is detected in steps S1 to S3, and processing corresponding to the function key is performed in steps S7 to S9. When the operator operates any of the edit keys 22, the operation is detected in step S4, and
At 10, a process corresponding to the edit key is performed. When the operator operates the cursor control key 24 or other keys, the steps S1 to S5
, A process for moving the cursor corresponding to the key operation and other processes are performed in step S6. When the operator operates the character keys 21 to input characters, after each character key is detected in step S5, the corresponding character code is set in the editing area to which the corresponding character code is assigned. Until an unknown word editing request is detected in step S2, the original text storage unit 3 is allocated as an editing area, and the contents thereof are displayed on the display unit 7. When an unknown word editing request is detected in step S2, the unknown word storage unit 10 is allocated to the editing area, and a display as shown in FIGS. 3 and 4 is made. For editing operations such as correction, insertion, and deletion, the cursor is moved to a desired editing location by operating the cursor control key 24, and then a correction key, an insertion key, a deletion key, etc. included in the editing keys 22 are used. It is done. When the editing key is pressed, it is detected by the editing control unit 2 in step S4, and each of the words or phrases indicated by the cursor control keys in the storage unit allocated as the editing area is input. An editing process corresponding to the key is performed. For example, inserting a character before the cursor position by operating the insert key, invalidating the character string in the range indicated by the cursor by operating the delete key, or changing the range indicated by the cursor by operating the movement key By moving the key to another position or operating the cancel key, the effect of the operation of the insert key, the delete key, the move key, and the like can be nullified. The cursor control keys 24 include a cursor movement key for moving a cursor in each direction,
The unit includes a unit switching key for switching the unit in which the cursor moves, and an enlargement / reduction key for enlarging / reducing the cursor size in character units or word units. The operator operates the unknown word search request key as needed while inputting / editing the original text.
It is possible to search for unknown words in the original sentence stored in the original sentence storage unit 3 and register them collectively by the dictionary registration unit 11. First, the unknown word search unit 9 will be described. As a method of searching for an unknown word, for example, a word close to the unknown word in the original sentence is extracted from the translation dictionary unit 5 and a ending change permitted by the part of speech of the word is performed. All possible possibilities of the word, such as plural form, progressive form, past tense, past participle, irregular change, etc., are obtained as matching candidates, and matching with the original sentence is performed. Alternatively, the prototype of the word of the unknown word may be obtained from the original sentence, and matching with the dictionary in the translation dictionary unit 5 may be performed. In that case, it is necessary to check that the ending change when the prototype is obtained after matching and the ending change due to the part of speech in the dictionary. As a result of performing the matching as described above,
Words in the original text that cannot be matched are stored in the unknown word storage unit 10 as unknown words. There are two types of unknown words, one is an unknown word due to an input error in the original sentence, and the other is correctly input but registered in the translation dictionary unit 5. It is the original unknown word that has not been done. For example, among the phrases searched for as unknown words by the unknown word search unit 9 illustrated in FIG.
“ear-only-memory” and “VDT” are originally unknown words, while “translater” is “tr
An unknown word due to a spelling error due to an input error of “ansator” is corrected in the original sentence storage unit 3, and the unknown word is corrected in the unknown word storage unit 10. The deletion may be performed using the delete key of the edit key 22. After the unknown word search is completed, when the operator operates the edit request key for the unknown word, the edit control unit 2 detects the unknown word at step S2 and the unknown word is detected. The word storage unit 10 is allocated to the editing area, whereby the searched unknown words are stored in the unknown word storage unit 10, and a list of unknown words is displayed on the display unit 7 in a format as shown in FIG. The operator moves the cursor and inputs a translation for an unknown word while looking at the display screen of Fig. 3. Input errors can be eliminated by using the delete key as described above. It is. As a result, the word of the original is unknown word in an unknown word storing unit 10, the corresponding translated word is added,
Further, a display is made as shown in FIG. When the input of all the translated words is completed, the operator operates the unknown word dictionary registration request key, and the unknown word added with the attribute information necessary for the translation of the translated word, part of speech, etc. stored in the unknown word storage unit 10. The word information is sequentially registered in the translation dictionary unit 5 in the following format, for example. Original phrase: translation: part of speech: other information In FIG. 4, the part of speech and other information are omitted. When the part of speech is omitted, it is sufficient to register the part of speech. The present invention is not limited to the above-described embodiment, but can be implemented with various modifications within the technical scope thereof. According to the present invention, an unknown word to be registered in the translation dictionary section and attribute information including its translated word can be registered collectively, so that a large number of unknown words can be shortened. It is possible to register a dictionary in time.
