基于本体的知识检索系统评估机制探析

Analysis of the Evaluation Mechanism of Ontology-Based Knowledge Retrieval System

近年来,基于本体的知识检索系统已成为信息检索领域最为活跃的研究方向之一,对此类系统进行评估是利用本体进一步提高其检索性能和智能性的主要依据。目前国内外在评估基于本体的知识检索系统的检索质量方面,还没有形成一套完善的、被广泛采用的评估机制。文章以此为切入点,对近几年国内外基于本体的知识检索系统评估机制进行了梳理,并在此基础上,对基于本体的知识检索系统的评估机制有待深入研究的热点进行了展望。

In recent years, the research about ontology-based knowledge retrieval system has become one of the most active research directions in the field of information retrieval. To evaluate ontology-based knowledge retrieval system is the main basis for using ontology to further improve its retrieval performance and intelligence. But now, there is lack of a perfect and widely adopted evaluation mechanism for ontology-based knowledge retrieval system. Based on this point, this paper clarifies the evaluation mechanism of ontology- based knowledge retrieval system at home and abroad in recent years, and prospects the future research focuses.
