摘要: 分布式环境下的异构案例表达制约了案例检索过程中案例属性之间的可比性,进而成为分布式环境下案例推理系统成败的一个关键问题。该文提出基于语义相似的案例检索,通过利用Ontology技术来理解案例属性的内在含义,在此基础上定义并计算属性之间的相似程度。对原型系统的初步测试证明了基于语义相似的案例检索有效性。

Abstract: Heterogeneous case representation in distributed environment decides whether the two features of two cases are the same and comparable in process of case retrieval. It is one of key problems of case-based reasoning (CBR) systems in distributed environment. An approach of semantic based case retrieval exploits a method to understand features of case using ontology technology. And based on the understanding of features, similarity between the two features is defined and computed. The experiment result of the prototype system verifies the efficiency of semantic based case feature mapping and case retrieval.

Key words: Semantic, Similarity, Case retrieval, Distributed environment
