A Novel Approach for Measuring Chinese Terms Semantic Similarity Based on Pairwise Sequence Alignment
Shuo Xu, Lijun Zhu, Xiaodong Qiao, Cun-xiang Xue · 2009
In this study, we first give a problem formulation for Chinese terms semantic similarity calculation. After that, on closer examination, we find that the traditional approach makes an implicit assumption that the order of corresponding primitive terms for two terms is roughly consistent. In other words, it doesn't consider how the difference in the order affects the quality of correspondence. To overcome this problem, a novel approach based on pairwise sequence alignment is proposed. Finally, an experimental evaluation is conducted, and the result indicates that our approach outperforms or matches at least the traditional one in the majority of cases.
