As a crucial point of semantic integration,ontology mapping is researched in-depth at home and abroad.The machine learning method is introduced to weights computing in combining concept similarities,and the weight allocation algorithm LMSW based on Widrow-Hoff theory is proposed.In LMSW,the weight vector most fitting the training samples is searched by gradient descent method,so that the final combined concept similarity can be attained,and the ontology mapping which combines multiple concept similarity strategies can be determined eventually.Experiment indicates that the method performs well in improving precision and recall compared to individually using other algorithms.
