基于领域约束本体的语义相关度计算研究

语义相关度计算是信息检索、文档分类和聚类、推荐系统、机器学习等诸多领域的关键技术之一。研究基于地学领域本体,综合考虑了本体层级信息量、本体拓扑结构等基础上,引入约束性本体,实现相关度计算算法。实验结果表明,加入约束性本体条件下实现的算法,相关度计算结果明显提高。

Research on Semantic Relevance Calculation based on Domain Constraint Ontology

Semantic Relevance Calculation is a key technology of information retrieval, document classification and clustering, recommendation system, machine learning and so on. In this paper, based on the domain ontology, the ontology level information, ontology structure and other information are taken into account. In addition, the constraint ontology is added to semantic relevance calculation. The experimental results show that the calculation is improved by adding the constraint ontology.
