文摘To improve the performance of the ontology matching process, a more efficient ontology matching algorithm, which can effectively eliminate unnecessary operations of matching entities, is proposed.

Thereby, redundant operations of matching adjacent entities can be avoided, which can improve the performance of the whole matching process.
