The invention discloses a Chinese syntax parsing method with merged semantic information, belonging to the technical field of natural language processing. The method comprises the following steps: step 1), extracting different hierarchical semantic classes of words according to the hyponymy of the knowledge network to obtain indexes from the words to the semantic classes; step 2), using a word in a syntactic tree as a key assignment and query the knowledge network to obtain a semantic class of the word and add the semantic class to a certain layer of the syntactic tree; step 3), using the syntactic tree after being processed in the step 2) as training data to train grammar so as to obtain a grammar model; step 4), utilizing the grammar model after being trained in the step 3) to decode a sentence to be analyzed. Compared with the prior art, the invention adopts the semantic information to disambiguate parsing so that the parsing effect is remarkably improved.
