摘要
针对现有自动答疑系统中知识表示的不足,提出了用本体构建课程领域知识库的方案。根据答疑问句的特点进行了问题分类,将用户问句意图转换为对本体中基本元素的查询,并通过Jena语句加以实现,最终抽取出答案,实验证明方案是可行的。
An approach to constructing course knowledge base with ontology was proposed to overcome the deficiency of knowledge representation in the existing automatic question answering system. Questions were classified according to their traits. The intention of a question was transformed into the query of basic elements in ontology, and was implemented via Jena statements, and the answer was extracted finally. The proposed approach is proved by experiments.
