An Improved Sentence Similarity Calculation Method Based on How-net
In order to overcome the defects of information redundancy interference and local optimum of sentence similarity calculation based on lexical item, this paper proposes a new sentence similarity calculation method based on how-net. This method reduces the interference of redundant information by adding a step of screening of statements, which obtains the global optimal maximal matching using the improved algorithm of maximum matching of weighted bigraph based on participle and speech tagging. The experimental results show that the method proposed in this paper can effectively improve the accuracy of sentence similarity computation.
