基于概念相似度计算的多策略本体映射研究
Research on Multi-strategy Ontology Mapping Based on Conceptual Similarity Computing
摘要
Abstract
Ontology similarity calculation is the pivotal to ontology mapping in the era of information overload. Considering that the cur-rent ontology mapping similarity calculation does not take full advantage of semantic information of each issue,an improved multi-strate-gy concept similarity computing approach was proposed to solve it. The method explores the similarity of ontology concept from four as-pects,including ontology concept name,attributes,hierarchies and instances,and in calculating the instance similarity,two key factors, difference degree and richness are used to solve the instance differences problem. Finally,with the sigmoid function,the weight of each strategy are automatically generated and used to combine mapping results to improve mapping quality. Apply two group data to compare with the RIMOM. The experimental results show that the method can effectively improve the mapping results recall and precision.关键词
