基于本体的信息检索模型研究

Research on ontology-based information retrieval system models

根据文档处理方式的不同,将基于本体的信息检索系统分为基于知识库的语义检索系统和基于语义网文档的信息检索系统两类。对这两个模型的实现原理和关键步骤进行了阐述;探讨了基于本体的信息检索模型中的关键技术,并指出当前研究中存在的不足;最后对基于本体的信息检索系统的研究热点和方向进行了展望。

According to manners in which documents were processed, divided the systems into two categories： knowledgebased semantic information retrieval model and information retrieval model based on semantic Web documents . Then, discussed how the two models operate and realize implementations and approaches. Further, studied the technologies involved in the models and claimed four research problems. In the end, predicted the hot research topics and developing trend.
