【摘要】 现有的语义网格信息检索过程,实际上只是用户请求的某些概念描述与网格本体的匹配,无法做到真正的本体与本体之间的匹配。在充分研究现有网格本体匹配算法的基础上,提出构造网格虚本体来形式化描述用户需求,即通过网格领域虚本体的构造为网格本体的匹配做铺垫,同时利用本体分层和图匹配来提高匹配的准确率,并对其匹配模式和匹配算法都有相应的改进和提高。更多还原

【Abstract】 The existing semantic grid information retrieval,which uses the description of the user’s needs to match the grid ontology in the fact,is not a real matching between ontology.On the research of the matching of grid domain ontology,this paper proposes to build a grid virtual ontology to give a formal description of the user’s needs,which means that we can do the groundwork for the matching of grid ontology through building the grid domain virtual ontology,and then uses the grid hierarchical and graph matching to increase the accuracy of the matching,and improves the existing matching model and matching algorithms respectively.更多还原
