摘要
选择核函数计算本体图边的权值,并利用图正则化模型得到优化函数,从而将本体图中每个顶点映射成一个实数,通过比较实数间的差值得到本体映射.实验表明该方法是有效的.
The edge weights regularization framework of gy graph are mapped as real of the corresponding values. of the ontology mapping are computed with the kernel function and, using the graph, the optimized function is obtained. Thus, all the vertices of the ontolo- numbers. Then the ontology mapping is obtained by comparing the difference An experiment has confirmed the validity of this method.
