Abstract

The invention discloses a method for computing semantic relevancy with consideration on relations between concepts. Semantic degrees computed by the aid of the common relations between every two concepts and semantic degrees computed by the aid of the independent relations of the two concepts are combined with one another on the basis of processes for computing basic similarity degrees, and accordingly ultimate semantic relevancy computation values can be obtained. The method for computing the semantic relevancy has the advantages that the relations between every two concepts are sufficiently considered, identical properties and respective unique properties are embodied during computation, and accordingly computation results are close to human judgment results and are accurate.

Description

technical field [0001] The invention relates to a calculation method of semantic correlation degree considering the relationship between concepts. Background technique [0002] Quite a few studies have elaborated on the calculation of semantic similarity. According to different methods and principles, similarity calculation can be divided into structure-based methods, context-based methods, attribute-based calculation methods and hybrid methods. [0003] The structure-based method is based on a certain domain ontology (Ontology), by comparing the path lengths of two concepts in the ontology library to calculate the semantic correlation. The larger the location distance, the smaller the semantic correlation, and vice versa. For example, the Wu and Palmer method, which will be compared later, and the Leacock and Chodorow method. This method has the least complexity in calculating semantic correlation, but the main disadvantage is that it needs to assume that the distances o...
