Abstract: Different from English, modern Chinese syntax has obvious complexities: one is not easy to get the complete set of rules; the second, sentence of the analytical results contains a lot of ambiguous structures which are difficult to eliminate. Decomposition policy can divide syntax analysis tasks into different levels of small tasks, which rather than on the complete syntactic analysis is feasible. The basic idea is that first of all, multi-layer Markov model was used to parse a sentence which cut apart the complete sentence to some phrase about noun phrase, verb phase, etc. On the basis of the chunk, CYK algorithm was run to analyze the dependencies of the chunk, and ultimately realize the complete sentence syntactic analysis. Shallow parsing simplified rule set of CYK algorithm, and reduce the syntax parsing to some extent.

Key words: shallow parsing, Hidden Markov Model (HMM), parse tree, dependence relationship
