Abstract

PURPOSE:To perform correct translation, by providing a complex sentence analyzer so that the relations between phrases and clauses of Japanese sentences can correctly be determined. CONSTITUTION:A complex sentence analyzer 1 is provided with a determining device 2 for the connection and relation of phrases and clauses and a processor 3 for participial modification. The device 2 is provided with a Japanese word dictionary 4, a grammer dictionary 5 and a dictionary 6 for significance to determine which phrases and clauses are modified ones. The processor 3 forms a sentence C' in which Joshi (postpositional word functioning as an auxiliary to a main word) of a sentence C is changed into the Joshi for the suggestion of topic, when a sentence B which can be a predicate of a sentence A can be a participial modification sentence of the sentence C, and if the connection is established between the sentences C' and B, the sentence B is regarded as the related sentence to the sentence C.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Japanese sentence analysis system that enables accurate analysis of which clause a clause that may be related to two clauses is related to.

As a method of translating a Japanese sentence into an English sentence, it has already been proposed to generate a conceptual structure expressed by the Japanese sentence and then generate an English sentence according to this conceptual structure. ◎To generate a conceptual structure from a Japanese sentence Convert 1 into a sequence of Japanese sentences, put out the two related sentences,
It is necessary to define the relationship between these two clauses: g! To do this, it is necessary to correctly identify two related phrases.0 For example, when there is a Japanese sentence such as ``She has beautiful hair,'' in the conventional technology, it is necessary to correctly identify the two phrases that are related. Sometimes people mistakenly think that the phrase ``to her'' is related to the phrase ``for her.''

The present invention is based on the above considerations, and aims to provide a 5K Japanese sentence analysis system that can accurately grasp the relationships between clauses in Japanese sentences.

Therefore, the Japanese sentence analysis V-stem of the present invention includes a Japanese word dictionary, a grammar dictionary storing information indicating grammatical result relationships between bunsetsu and bunsetsu, and a semantic connection relationship established between bunsetsu and bunsetsu. A semantic relational dictionary storing information indicating whether or not to use a word, and the Japanese word dictionary described above.

Japanese sentences are analyzed using a grammar dictionary and a semantic relationship dictionary, and the dependencies between clauses are determined. In a Japanese sentence analysis system that has a determination device, clause A and clause B are determined.
When the relationship is established, the dependency is constantly analyzed, and then
When it is determined that there is an adjunctive modification relationship between clause B and clause 0, change clause 0 to clause 0' indicating main -,
When there is a relationship between bunsetsu 0' and bunsetsu B, there is no relationship between bunsetsu A and bunsetsu B, and there is a relation between bunsetsu B and bunsetsu C. The present invention is characterized in that it is equipped with a recombinant modification processing device. Below 1
The present invention will be explained with reference to the drawings.

The figure is a diagram illustrating an embodiment of the Japanese sentence analysis system of the present invention. In the figure, 1 is a complex sentence analysis device, 2 is a dependency determination device, 3 is an adnominal modification processing device, 4 is a Japanese word dictionary, 5 is a grammar dictionary, and 6 is a semantic relationship dictionary.

The complex sentence analysis device 1 includes a dependency determination device 2 and an adjunctive modification processing device 3. In addition, a complex sentence is one in which there are two or more clauses that can be used as clauses in which uke is dependent on a clause.
And, using the meaning relation dictionary 6t, it is determined which clauses are related clauses and which clauses are uke-wa clauses. When clause B, which can be a predicate clause of clause A, can be an adnominal modification clause of another clause C, the adjunctive modification processing device 3 generates clause C in which the particle of the other clause C is changed to the particle of topic presentation "wa". ', and if there is a relationship between clause C' and clause B, then clause B becomes clause C.
It goes without saying that when performing the 64-unit modification process mt for something that is related to the Japanese word dictionary, the grammar dictionary 5 and the semantic relationship dictionary 6t- are also referred to. Japanese Dictionary 4 can be thought of as having the same content as a regular dictionary.

Other grammatical information such as pronunciation, part of speech, semantic information, and usage #j1 degree are stored. The grammar dictionary 5 stores information such as, for example, that a grammatically related relationship is established between a noun clause and a verb clause.The semantic relation dictionary 6 stores 2.
The present invention will be explained in detail using a zero-order KA field example in which information indicating whether a semantic connection is established between side clauses is shown. The sentence "." is input into the complex sentence analyzer IK large 0. ■ The relation between the phrase "she is" and the phrase "envious" is established, and the relation p is determined by the determination device 2.
is analyzed.

■ Since there is an adjunctive modification relationship between the phrase “beautiful” and the phrase “hair,” the adjunctive modification processing device 3
tr is changed to ``hair wa'', and it is checked whether a dependency relationship is established between ``hair wa'' and ``beautiful''. In this case, it holds true.

It is assumed that there is a relationship between the phrases ``she is'' and ``beautiful,'' and there is a relationship between ``envy'' and ``take money''. A relationship can be established between kaishi uke and the phrase ``motteru.''

Interchange 9 Uke' Analyzed by analysis device 2 O ■ A dependency is established between ``Kojo wa'' and ``I'm in charge'', and a dependency is established between ``Beautiful'' and ``Hair''. What is being done will be output.

As is clear from the above explanation, according to the present invention, the dependencies between clauses in a Japanese sentence can be determined in a precise manner, and as a result, by using the present invention, one correct translation can be obtained. It becomes possible to abuse the power of doing it.

Claims (1)

[Claims] A Japanese word dictionary, a grammar dictionary storing information indicating the grammatical result relationship between bunsetsu and bunsetsu, and information indicating whether a semantic connection relationship is established between bunsetsu and bunsetsu. A semantic relational dictionary that stores information indicating. The Japanese sentence analysis system Kk has a device for determining the dependency between clauses by analyzing Japanese sentences using the above-mentioned Japanese word dictionary 1 grammar dictionary and semantic relationship dictionary. After the dependency relationship with kB is analyzed, if it is determined that there is an adjunctive modification relationship between clause B and clause C, the above clause C is changed to clause C' indicating the subject. However, if there is a relationship between bunsetsu C' and bunsetsu B, there is no relation between the bunsetsu person and clause B, and there is no relation between bunsetsu B and bunsetsu C. Japanese sentence analysis system 0 characterized by the installation of an adjunctive modification processing device with 6 characters.
