| 摘 要： | 传统的语义相似度算法采用纯语义距离或以本体库的统计特性为基础。论文的改进算法把这两者结合起来,互为约束,并且加入了“深度”和“密度”对语义距离的辅助影响。改变语义相关性的比重只需调节算法中的一个参数。最后通过WordNet构造的局部语义树,比较了各算法的有效性。

| Abstract: | Traditional arithmetic of semantic similarity is based on the simple semantic distance or certain statistical property of some Ontology.Our arithmetic try to combine these two aspects for inter-restriction in our schema,and take the assistant influence of 'depth' and 'dense' into account.Only one parameter need to be modified if we want to adjust the proportion of semantic Relativity.In the last part,we have constructed a part map of the semantic tree using WordNet in order to compare the validity of each arithmetic. |
