Abstract

PURPOSE:To easily translate even a polite style by permitting a user to designate a translated sentence use purpose. CONSTITUTION:If the user designates translation in a polite style when he desires, a translated sentence style designation input part 5 receives it and transmits translated sentence style designation information to the translated sentence generation part 4 of a translation control part 2. Thus, information which is originally given to intermediate expression is processed and a processing is executed in a translation rule, whereby it is translated into the designated style. To put in concretely, processings expressing the inflection in the polite style differ by the type of the sentence which intermediate expression has (imperative sentence/a declarative sentence), the presence or absence of negation, tense information and information on a part of speech and the inflection as the result of original analysis, which a Japanese dictionary has. A calculation processing is executed by a generation rule based on the information and style information by user designation, and it is executed by giving information on auxiliary words 'desu' and 'masu'. The processings have regularity and they are processed by three prescribed patterns. Thus, a regular style and the polite style can be selected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine translation device.

[0002]

2. Description of the Related Art A conventional machine translation method will be described below with reference to FIG.

The input original text is passed to the translation control unit 2, and the dictionary file 6 and the knowledge base 7 are referred to.
The original sentence analysis unit 3 analyzes the original sentence and obtains an intermediate expression representing the meaning and content of the original sentence. Then, based on the intermediate representation, the translation generation unit 4 generates a Japanese translation and outputs it. Further, this knowledge base 7 includes analysis rules for analyzing the original sentence to obtain an intermediate expression, and a generation rule for calculating information of the intermediate expression and generating a Japanese sentence. And translated to.

Since the translation is performed in such a flow, the conventional system unconditionally translates in the normal form such as "is".

Some word processors have a style retrieving function for converting a normal body into a polite one, but that function requires the user to search for a word to be converted and input the translated word one by one. Therefore, it is not possible to deal with individual words collectively.

[0006]

As described above, in the conventional machine translation device, the translation is performed unconditionally and uniformly in the normal form, but depending on the purpose of use of the translated sentence, it is better to translate in the polite form. In some cases. There are two problems when the machine translation device is used to express it politely. One is that the polite body is a linguistic phenomenon peculiar to Japanese, and there is no information in the original sentence so that an intermediate expression cannot be generated. The other is the part-of-speech of a word, its conjugation type, and the type of sentence. , The expression changes depending on the presence or absence of denial and the tense, and it cannot be processed uniformly.

[0007]

A machine translation apparatus according to the present invention is designed so that a user can specify a translated sentence style to collectively generate a translated sentence according to a purpose of use. It is characterized by having a function that can be translated by any of the above.

[0008]

In order to solve the above problems, the present invention allows the user to specify the translated sentence style so that the normal style and the polite style can be selected.

As a user designation method, a method of designating a polite body when it is desired to translate it in a polite form, and translating it in a normal form when not designated is adopted.

In the case of a polite body, the part of speech of the word, the inflection type,
Regardless of sentence type, denial, tense, etc.
We adopt a method of processing in three patterns so that they can be translated correctly.

[0011]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
1 is an input control unit, 2 is a translation control unit, 3 is a source sentence analysis unit, 4
Is a translated sentence generation unit, 5 is a translated sentence designating unit, 6 is a dictionary file, 7 is a knowledge base, and 8 is an output control unit.

The original sentence is input to the input control unit 1 and passed to the translation control unit 2. The translation control unit 2 refers to the dictionary file 6 and the knowledge base 7, analyzes the original sentence in the original sentence analysis unit 3, and obtains an intermediate expression representing the meaning and content of the original sentence described above.

When the user wants to translate in a polite style, if the user specifies the translation style "polite style", the translation style input unit 5 accepts it and transmits the translation style designation information to the translation generation unit 4 of the translation control unit 2. As a result, the translation rule is processed in the same manner as the information originally contained in the intermediate expression is processed, and the specified style is reflected in the translation. next,
Specifically, how the polite body designated by the user is processed by the knowledge-based translation rule will be described with reference to FIG.

As a result of analyzing the original sentence, the process of expressing the inflection word in polite form has the type of sentence (imperative sentence / plain sentence), the presence / absence of negation, tense information, and the Japanese dictionary possessed by the Japanese dictionary. The processing differs depending on the part-of-speech and inflection-type information that the Japanese dictionary has, and
As a result of analyzing the original sentence, the processing differs depending on the type of sentence (imperative sentence / plain sentence) that the intermediate representation has, the presence or absence of negation, and the tense information, and a generation rule based on these information and stylistic information specified by the user. It is calculated by adding the auxiliary verbs "is" and "masu" information.

There is regularity in these processes, and FIG.
, Three patterns shown in FIGS. 3 (b) and 3 (c).

First, pattern 1 is a case of an adjective, an adjective conjugation word, an adjective verb, and "is". To give an example, actually, for example, the expression "she is beautiful." Can be expressed politely, but "she is beautiful." Absent. In addition, even in sentences that express the past, "she was beautiful." In negative sentences, she says, "I'm not beautiful." At the end of the sentence, I add "masu." In past negative sentences, I say, "She was not beautiful." At the end of the sentence. The following pattern 2 is for the adjective verb type inflection word. For example, the example sentence "He seems to be happy." Is expressed in a polite manner as "He seems to be happy." Put on. Also, in a sentence that expresses the past, "he seemed to be happy." Is added, and "is" is added at the end of the sentence. In negative statements, he says, "He doesn't seem to be happy." And puts a "masu" at the end of sentences, and in past negative statements, "He didn't seem happy." Append "masu" and "is" at the end of the sentence. The final pattern 3 is the case of all inflection words other than patterns 1 and 2. To give an example, let's say, for example, the expression "He runs." When expressed in a polite manner, "He runs."
And add "masu" to the end of the sentence. In addition, "masu" is added to the end of each sentence to express the past or the negative sentence, and it is expressed as "he ran.""He does not run." In the past negative sentences, "he did not run." Is expressed and "masu" and "is" are added at the end of the sentence. When the user politely specifies, the above processing is performed and the translated text is output.

[0018]

As described above, according to the present invention, originally, the translation is uniformly performed in the normal form. However, the translation can be performed in the polite form by the user's designation according to the purpose of use of the translated text. It is a thing.
