摘要
传统通用搜索引擎用于渔业信息检索存在返回结果的召回率和准确率较低的缺点,分析了产生这一问题的原因,阐述了本体的应用领域以及将本体用于渔业信息检索的可行性,用实例说明了渔业领域本体的构建过程;在此基础上提出基于本体的智能渔业信息检索系统体系结构,并用Java和Jena实现了该系统。实验结果表明采用该体系结构的渔业专题检索系统的召回率和准确率均优于传统的通用检索系统。
The recall and the precision of the traditional searching engine used to query fisheries information are lower.The application of ontology used in fisheries information retrieval is discussed and its feasibility is analyzed.An example is given to illustrate the course of the fisheries construction,and the structure of intelligent fisheries information retrieval system is presented based on the ontology.The system is implemented with Java and Jena. The experimental results show that the recall and precision of the system structure is better than the traditional searching system in the fisheries information retrieval system.
