中文简介:
语义Web应用程序的自动知识重用给本体搜索带来了一些挑战。现有的本体检索系统只返回相关的单个本体的冗长列表，这可能无法完全覆盖指定的用户需求。因此，对一种工具或算法的需求越来越大，这种工具或算法具有一种机制来检查现有本体对用户查询的概念充分性，然后推荐一个或多个本体的组合来完全满足需求。因此，本文开发了一种算法，即CombisQore，来确定可用的本体集合是否能够完全满足提交的查询，并返回一个保证查询覆盖率的单一或组合的本体。此外，它根据返回的答案的概念紧密性和查询覆盖率对它们进行排序。实验结果表明，该算法简单、高效、有效。
课程简介: Automatic knowledge reuse for Semantic Web applications imposes several challenges on ontology search. Existing ontology retrieval systems merely return a lengthy list of relevant single ontologies, which may not completely cover the specified user requirements. Therefore, there arises an increasing demand for a tool or algorithm with a mechanism to check concept adequacy of existing ontologies with respect to a user query, and then recommend a single or combination of ontologies which can entirely fulfill the requirements. Thus, this paper develops an algorithm, namely combiSQORE to determine whether the available collection of ontologies is able to completely satisfy a submitted query and return a single or combinative ontology that guarantees query coverage. In addition, it ranks the returned answers based on their conceptual closeness and query coverage. The experimental results show that the proposed algorithm is simple, efficient and effective.
关 键 词: 本体检索系统; 概念亲密; 查询覆盖
