The Theory Of BSCM Presented And The Implementing Of The Natural Language Understanding Studied

The theory of BSCM presented and the implementing of the natural language understanding studiedDiscussing the grammar and difference between Chinese and English, we know the semantic problem of the computer understanding Chinese. The semantic Chinese's theory has not been set up for the semantic Chinese always comparing with the Indo-European. There existed a lot of problem from this way for the computer understanding Chinese. So the formulation of Chinese for the computer understanding was not always so well.And now I present a new theory on the problem of the modern semantic Chinese for the computer understanding Chinese. The theory is called BSCM. BSCM means basic semantic Chinese meaning.At first I think the concept on the deep structure and surface structure in the Chomsky's theory of the transformation grammar is right. But the grammar system can produce the English sentence; it can't produce the Chinese sentence. The command way is the semantic Chinese composing of the deep semantic structure and the surface semantic structure. The deep semantic structure corresponds to the PtBM (pointing to the basic meaning) with the BSCM. The PTBM controls the concept of theme in Chinese sentence. It controls the corresponding the relation between the subject (the first principal part ; stands for the man or the man's action, or the man's thing or the speaker who makes the sentence ) and the object (the second principal part; stands for the second man or the second man's action, or the second man's thing or the listener who listens the sentence, the listener who accepts the sentence). The semantic relations between subject and object without limitation compose of the sentence. The surface semantic structure corresponds to the PtBSM (pointing to the basic semantic meaning) with the BSCM. The PTBSM controls the corresponding formulation of the Chinese sentence. It controls the relations among the subject, object and the relation of the PTBSM between the subject and the object. So the formulation of the semantic structure of the Chinese sentence is:[subject+object]{[relation of PtBSM]}{PtBM}Semantic sentence BSCM PtBM+PtBSM first object{semantic subject+semantic object}[PtBSM]{PtBM}{Subject[word's basic meaning] {word's sentence meaning}+Object[word's basic meaning]{word's sentence meaning}}note: Object[word's basic meaning]{word's sentence meaning}} {Subject[word's basic meaning]{word's sentence meaning}+Object[word's basic meaning]{word's sentence meaning}} {Subject[+YN ]{[+Su {+PT }]}+[Object] [+YN ]{[+SM{+PT}]}} Object[+Y N ]{[+SM {+PT }]}=>{Subject[+Y N ]{[+S M{+PT}]}+[客体[+Y N ]: Y is the word's basic meaning of the (Word),. 's language formulation, {[+SM{+PT}]}:S is the word's basic meaning of the concept of theme, P is the word's sentencemeaning; N. M, T 0,1,...,n; the concept of theme:{+P}[+S]The division of the subject and object is a pair of relative concepts. It is definite relation in the corresponding the sentence's relation of the PtBSM. The PtBSM is the semantic relation between man and the thing. The man is defined to the subject. The thing is defined to the object. The relation of the PtBSM is the semantic relation between the thing and the thing. The thing is still the object relative to the man. That's the semantic relation between the object and the object. If there exists the relation of PtBSM between the object and the object, the forward object is the subject relative the backward object with the relation of PtBSM. The ten words class are redefined the respective concept of the subject ,object and the relation of PtBSM.A definite formulation corresponds to the concept of the connotation and extension of BSCM for the computer understanding. The connotation is for the PtBM. The extension is for the PtBSM.The basic genus is the concept of the theme. The concept of the theme includes a few couples of the basic genus. A basic genus includes a relative subject element and another relative object in Chinese sentence.The genus is the associated concept of th...
