摘要
本体映射是解决本体异构的通用方法.根据边的类型、顶点深度、边的密度和强度以及边关联的两顶点的属性计算有向边的权重.选择最优路径构建对应本体有向层次图的无向生成树,分别定义其Laplace矩阵,并通过分析该矩阵的特征值及特征向量来构造匹配矩阵.最后根据匹配矩阵元素的大小和位置信息来实现顶点匹配,并由此生成本体映射.实验表明该方法是有效的.
The general solution of ontology heterogeneity is ontology mapping.Computed the edge weights according to the type of edge,vertex depth,density and intensity of edges and attributes of vertices associated with edges.Obtained undirected spanning tree by choosing the optimal path.Defined Laplacian matrices respectively,analysed the eigenvalues and eigenvectors of the matrices,and constructed a matching matrix with information of magnitude and position of entries in the matching matrix,and thus generated ontology mapping.Experiments showed that the method was effective.
