A kind of calculation method of Chinese sentence structure similarity

The sentence structure similarity measure is an important contents in the study of clause relevance. The accuracy of Chinese Sentence Similarity Measure will directly affect the final results of the relevance of clause. This paper proposes a method for Chinese sentence structure similarity measure. The method compares the parts of speech string corresponding to two small sentences of an Chinese complex sentence, and find the most similar structure and the most effective parts of speech sequence, then calculate the structure similarity of two clauses combining with word shapes. This method can also excludes the effect on computing the similarity of the structure from the differences of the length between two clauses. Finally, the preliminary experiment show that the method is feasible and effective.
