摘要
随着网络技术的发展和Internet上信息量的激增,信息检索系统作为网络信息平台的一个重要组成部分,在用户获取准确的网络信息过程之中发挥着重要的作用。传统的检索技术不能对这些信息提供语义级的组织、理解以及处理,寻找新的方法成为目前研究的热点。在现有语义检索方法的基础上,以本体为依据,提出了基于本体的信息检索系统。通过构建领域本体和推理规则,运用Jena实现了语义推理与检索功能,得出潜在的语义查询结果。提高了检索的查全率与查准率。
With the development of network technology and rapid increasing information on Internet, information retrieval system plays an important role at communication between users and resource on the network. Traditional information retrieval technologies can not meet the needs for better organizations, understanding and processing services in the semantic level; therefore, to find new ways has also become a hotspot of current research. Based on the existing semantic retrieval methods, a novel information retrive system based on ontology is proposed in this paper in order to overcome the limitation. The results of potential semantic were gained by building domain ontology and reasoning rules, and implemented semantic reasoning and retrieval function by means of using the Jena. The experiment resutls have proved that the system has higher recall and precision.
