DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine translator for translating an object to be translated into a counterpart language.

[0002]

2. Description of the Related Art A machine translation apparatus has a translation dictionary for analyzing an original sentence, converting the original sentence to a counterpart language, and generating the translated language. This translation dictionary contains morphological information of the original sentence (the composition of headwords and headwords), part-of-speech information, information on inflections, syntactic information if a verb, and translated word information (headwords of translated words and part-of-speech of translated words). ) Etc. Among them, the syntactic information of the verb includes the syntactic pattern of the verb (generally five sentence patterns, etc.), the superficial case (nominative case, object case, etc.) and the syntactic form (noun, adjective, infinitive, Currently has information such as participle).

[0003] In the machine translation apparatus, a translation execution unit proceeds with processing while referring to the translation dictionary.

[0004]

In general, when a transitive verb has a gerund (ing form) as an object in the English syntax, it is translated as "to do something." For example, when the original text is "I shall never forget hearing him sing the song.", The gerund "hearing" is referred to as "listening" (present tense), and "I I will never forget to listen. "(1st translation).
In a conventional machine translation apparatus, the same translation as described above is performed uniquely.

[0005] However, when the transitive verb is a gerund as an object, it is often more appropriate to express the translation of the gerund in the past tense as "to do". If this expression is used, when the above original sentence is given, the gerund "hearing" is "listened to" (past tense).
"I will never forget hearing him sing the song" (2nd translation).

Here, comparing the first translated sentence and the second translated sentence, the second translated sentence is more literate in Japanese, and it is desirable that the original sentence be translated like the second translated sentence.

However, in a conventional machine translation device,
Such circumstances were not taken into consideration, and when translated using the data of the translation dictionary, only awkward translations like the first translation were obtained.

An object of the present invention is to provide a machine translator capable of obtaining a well-translated sentence.

[0009]

According to the present invention, there is provided a machine translation apparatus for translating an input original sentence into a translated sentence,
Storage means for storing an input original sentence, a translation dictionary having, in the syntactic information of the verb, the tense information of the translation of the word serving as the object of the verb, and the tense information of the translation of the word serving as the object of the verb in the translation dictionary , A translation control means for generating a translation from the original sentence stored in the storage means, and an output control means for outputting the translation generated by the translation control means.

[0010]

The syntax information of the verb of the [action] translation dictionary is provided with a tense information of the translation of the objective case word of the verb, in particular, those translation of the term and the objective case is the past tense "Appropriate" and those not so are "No".

The translation control means refers to the translation dictionary in the course of translation and, when translating the verb's object, refers to the tense information of the translation of the word to be the object of the verb, and if the information is "suitable". If so, a past tense translation of "do what" is generated, and if "no", a present tense translation of "do what" is generated.

[0012]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a machine translation apparatus according to an embodiment of the present invention, and FIG. 2 is a functional block diagram.

Reference numeral 1 denotes an input device such as a keyboard and an OCR for inputting an original sentence and giving instructions for translation, and corresponds to the input unit 7 in FIG. A program storage device (ROM) 2 stores a program for performing a translation process and a program for performing a dictionary search. A central processing unit 3 executes a program and controls an input / output device. Reference numeral 4 denotes a memory (RAM) for storing an input original sentence and a translated translation, and for storing a dictionary common table and necessary dictionary records, and corresponds to the work buffer (storage unit) 8 in FIG. Reference numeral 5 denotes an output device such as a printer for printing a translation process and a translation result, and corresponds to the output unit 13 in FIG. Reference numeral 6 denotes a disk device for storing dictionary information, which corresponds to the translation dictionary 11 in FIG. A is an instruction unit (reference numeral 10 in FIG. 2) such as a mouse for acquiring a processing instruction for the original text. In FIG. 2, reference numeral 9 in FIG. It is a translation control unit realized by this.

When an original sentence is input from the input unit 7, the original sentence is temporarily stored in the work buffer 8.
Then, the translation control unit 9 performs a translation process on the original text in the work buffer 8 according to an instruction from the instruction unit 10.
In this translation process, the relevant record is loaded into the work buffer 8 with reference to the translation dictionary 11 to obtain necessary word information. The translation control unit 9 analyzes, converts, and generates an input sentence while referring to this information, and displays a translation process and a translation result on the display unit 12 and outputs it to the output unit 13.

Here, the gist of the present invention is to set a past tense mark as past form translation appropriateness information in a case slot of syntax information of the translation dictionary 11.

Hereinafter, the original text “I shall never forget hearing h” described in the section of the problem to be solved by the invention is described.
im sing the song. "

The above example sentence is translated using the translation dictionary 11 of FIG. First, a headword is searched from the morphological information 14 and analyzed. At this time, when "forget" is searched for in the translation dictionary 11, "the transitive verb takes a gerund (ing form)".
Syntax information 15 can be obtained.

The process up to this point is the same as the translation process in the conventional machine translation apparatus, and therefore, detailed description is omitted.

At this time, the present invention refers to the syntax information 15 in the translation dictionary 11 and refers to the past tense mark of the case slot when the surface case is the target case. At this time, the past tense mark 17 of the translated word in the syntax information 15 of the case slot is turned on (suitable). Therefore, of the analysis information of "forget", the past tense mark of the translated word in the data area storing the information of the target case is turned on (suitable). In the following, analysis conversion for other words is performed.

In the process of generating a translated word, the translation control unit
The past tense mark of the translated word in the data area is referred to, and since this mark is on (suitable), the translation is performed using the past tense translation of "to do what" as a case particle equivalent.
Therefore, when the above original text is translated, "I will never forget that he sang the song", and a natural Japanese translation can be obtained.

[0022]

According to the present invention, the syntactic information of the verb has the tense information of the translated word of the word that is the object of the verb, and the translation is executed using that information. A tense expression of a translated sentence can be generated, and a natural translated sentence can be obtained.
