基于本体的个性化检索技术研究

Research on Personalized Retrieval Based on Ontology

近几年信息检索技术飞速发展,但很多搜索引擎都存在检索精度不高,检索结果不够个性化等问题。本文提出一种基于本体的个性化检索方法,在记录用户手动标注的信息生成一个个性化倒排索引的同时,再将其与本体知识相结合,进一步明确概念和语义关系,使得用户输入相同或相近的检索词时也能反馈用户曾经标注过的文档信息,从而满足用户的个性化需求。

The technology of information retrieval has developed fast in recent years. But mang search engines still have some problems such as inprecision and impersonalization. A way of personalized retrieval based on ontology was proposed in this paper. The idea consciously capturd keywords through mouse moving path to generate a personalized inverted index, then combined with ontology to make relationship of concept and semantic dear. Finally, users could search the marked documents when inputing the same or synonymous words to improve results of person- alized search.
