An Improved Concept of Semantic Similarity Computation Algorithm based on Domain Ontology

To effectively solve the problem of semantic similarity between concepts, the existing concept semantic similarity computation methods were studied and an improved concept semantic similarity computation algorithm based on domain ontology was put forward. In the process of computing concept semantic similarity the algorithm not only considered the basic relationships but also the custom relationships between concepts. In addition, the algorithm also took into account the concept of properties, and the concept of instance impact on semantic similarity computation. All these measures make the effectiveness of the algorithm in computing concept semantic similarity improved. The example showed that in the aspect of concept semantic similarity computation the proposed algorithm is more effective than the existing algorithms.
