基于本体语言标注的数字图书馆信息源检索模式

The Information Retrieval Mode of Digital library Based on Ontology-based Language Tagging

使用基于本体的语言标注能有效地避免词汇上的歧义,全面提高数字图书馆用户信息检索效率。本文以生物学为例,采用本体的语义辨析来分析用户给定的关键词,揭示这几个关键词所指向的概念,介绍了生物信息领域本体构建方面的工作,探讨了领域本体构建过程中的语义标注方法。

Abstract： The use of the ontology-based language tagging can effectively avoid ambiguous terms and considerably improve the digital library user＇s efficiency in information retrieval. Taking biology as an example, this paper uses the ontology＇ s semantic discrimination method to analyze the user＇s keywords, reveals the concept of these keywords and describes the construction of the ontology in the field of biological information. Finally, the paper discusses the semantic tagging method for domain ontology construction.
