Concept Similarity Calculation and Application in OWL
Zhi Dong-jie · 2008
In order to improve the recall and precision,similar concepts are often processed during the information retrieval.With this regard,the possibility of evaluating concept similarity is acquiring an increasing relevance,since it allows the identification of different concepts that are semantically close.Concepts in OWL have two features.Firstly,as son concepts inherit their father concepts' attributes,so all concepts form a hierarchical taxonomy tree.Secondly,concept's attributes are defined by asserted conditions including the ones inherit their father concept's.The computing model also has two parts.First part is using recursive algorithm to compare concepts' attribute similarity.The second part is to calculate concept similarity by using the amount of same attributes.
