A Method of Ontology Mapping Based on Classifying Schema Structure
Fan Ren-hong · Dianzi xuebao · 2011
Ontology mapping plays a key role in semantic integration area,a top-down ontology mapping method is proposed by this paper,it considering four basic mapping and this mapping process is assumed that all cases are 1:1.This approach describes the ontology as a graph and each ontology concept defined as a tree,on the basis of the tree,give the similarity computation method of leaf nodes and non-leaf nodes,merge the concept sub-tree by concept classification,According to the results of classification re-organization ontology chart structure.Finally,give a complete ontology mapping model.If the number of ontology is greater than two,concept of group separation method will be used,that is,a similar ontology in the same group,no similar in a different group,the separation date until convergence.Experimental results show that the layer classification ontology mapping method can reduce non-related concepts among count for large scale structure ontology mapping for the efficiency and accuracy it achieve the desired results.
