Abstract:
Natural language processing technology is an important direction in the field of computer science and artificial intelligence,and the Chinese text information extraction is a new rising researching field in recent years.Due to the character of the loose structure of Chinese text,the flexibility of grammar and semanteme,the research of Chinese natural language processing has a difficult challenge nowadays.In the paper,a method of the combine of syntactic and HMM(Hidden Markov Model)was proposed.The main idea is to use syntax to analyze the Chinese text,then submit the syntactic structure to HMM and get a HMM model through learning it,finally the event properties can be extracted by the HMM model.The experiment shows that the method has higher precision and recall than normal algorithm.
