Tagging Conjunctions In Complex Sentences Based On Du-yue Matrix And Context Computing Model

Natural Language Understanding is one of the most classical problems in the AI area. There are a lot of researches in domestic and overseas at the present time. Concerned to Chinese information processing, it should contain character processing, words processing, sentences processing and paragraph processing. Up to now the groundwork of Chinese understanding studies is very week. Now Chinese information processing researches are basically resting on the "characters and words processing" stage, and most researching products are based on characters and words. Researches on sentences especially complex sentences are comparatively rare. The reason is probably of the difficulty of Chinese language which has flexible syntax and semantics, unstable form, and is much different from the western language.Chinese sentences can be divided into two classes by structure, and they are simple sentences and complex sentences. The meaning capability of complex sentences is usually much bigger than single sentences, and they often present the logical meaning relations between people and people, things and things, people and things. Complex sentences constitute of clauses, and each clause is a single sentence viewed from its structure. Complex sentence has complex and special structure of its' own, and it's a kind of connection of simple sentences. As a sort of syntax entity, complex sentence connects simple sentences as its down level and connects paragraph as its up level. It has a good linking up function between simple sentences and paragraphs, and it also have many properties among syntaxes,semantics and pragmatics.The level relations is the soul of the compound sentence in a sense, compound sentence relations word marking relates the vital role to the compound sentence level, along with to compound sentence research thorough, the compound sentence relations word function appears more and more important, how effectively carries on labelling to the compound sentence relations word is urgent and important.Firstly this article introduced about some concept and the interrelated knowledge of the compound sentence domain.Then introduced the knowledge of the conjunctions of the compound sentence, and introduced the labelling compound sentence conjunctions based on the ruled method,the du-yue matrix method and context computing module which principles are based on the probability statistics. Synthetically use these methods can carry on effective labelling.
