ONTOLOGY CONCEPT UPDATE METHOD BASED ON SEMANTIC SIMILARITY
摘要
Abstract
To realize the automatic updating of ontology concepts and reduce the excessive dependence on domain experts,a semantic similarity-based ontology concept update method (SSOCUM) was proposed.An improved similarity algorithm based on WordNet was implemented.Based on the calculation of the path length,the algorithm took into account the concept of the node depth and the impact of the amount of information on the similarity.To make up several inadequacies that semantic information of property was neglected by WordNet-based similarity algorithm,property similarity was taken into account to make an adjustment.Through experimental comparison,it is verified that the Pearson coefficient between the improved algorithm and the standard data set is higher than the traditional algorithm,and the calculation result as closer to human subjective judgment.The constructed SSOCUM algorithm was used to analyse the ontology of coal mine ventilation system.The results show that the SSOCUM algorithm can help to automatically add ontology new concepts,and has certain accuracy and validity.关键词
