| 摘 要： | 将语义相似度计算模型定义为域、概念、属性组成的三维空间模型,并结合领域本体集,从概念格理论的角度考虑了该模型对语义相似度计算的影响.该模型通过对不同的向量加不同的权值来调节其对语义相似度计算的贡献,使计算结果达到最优,从而提高语义相似度计算的准确度.实验结果表明,与单方面计算相似度的方法相比,该方法能有效地提高语义相似度计算的查全率和查准率.

| Abstract: | In this paper,the computing model of semantic similarity is defined as a three-dimensional model consisting of domain,concept and property.At the same time,according to the domain-specific ontology set,from the perspective of the theory of concept lattice,the paper studies the impacts of this model on the semantic similarity computing.This method assigns different weights to different features to adjust the contributions of each feature to the semantic similarity computing model in order to achieve optimal ... |
