一种基于本体的信息检索方案

摘要

This paper presents an ontology based information retrieval model and further increases the comprehension capability of a system to a natural language document by constructing a domain ontology. This paper also introduces design and use of its three abstract layers. This paper eventually employs a polymerization function to consolidate and assess an inquiry result in order to acquire a well-matched document with the result.%描述了一种基于本体的信息检索模型,通过构造领域本体来有效提高系统对自然语言文本的理解能力,具体介绍了查询模型中三个抽象层的设计及使用,最后利用聚合函数对查询结果进行合并与评价,使用户最终得到与检索要求内容匹配度较高的文档.
