The Analysis And Processing Of The Type,Structure And Transform Of The Semantic Chunk

HNC puts forword the principles of the Alternation Engine and the Translation Engine which will be used in the Natural Language Processing.The Alternation Engine has 3 steps:from the grass roots of the concept space to the first floor---Sentence Category Analysis; from the first floor to the second floor---Sentence Group Unit Extraction and from the second floor to the superstratum of the concept space---Abstract(Huang zengyang 2004).The Translation Engine has 6 Transiton Processing : the conversion of the Sentences Category and the conversion of the Sentences Formula; the tansform of the structure of the Sntence Cunk and the transform of the Main Chunk and the Accessorial Chunk; the adjust of the separation of the Main Chunk and the position of the Accessorial Chunk, the adjust of the order of the Sentence Group.This thesis is the the basis of the Alternation Engine and the Translation Engine,the material contents :(1).Discusses the Alternation Engine and the Translation Engine,and advances two basic hypothesises;(2).Analyses the characteristic of structure of the Semantic Chunk;(3).Classifies the Accessorial Chunk and differentiate and analyse discriminate the different AC.(4).Sums up the disciplinarian of the the transform of the Main Chunk and the Accessorial ChunkThe Main Chunk has been studied more carefully in the level of sentence than the Accessorial Chunk,but AC has an important role in the study of the context.This thesis makes the primory study of this subject.
