摘要

在本文中,我们提出了一种利用医学词库来提高生物医学信息检索效率的方法。我们分析了现有医学词库的不足之处,并根据ANSI/NISO Z39.19-2003标准重构了一个新的医学词库MEDTHES。MEDTHES还通过提供计算词间语义相似度的功能,赋予用户对信息检索的细粒度控制。我们通过一个现有的数据搜索引擎演示MEDTHES的用法。

Semantic-based information retrieval of biomedical data
In this paper, we propose to improve the effectiveness of biomedical information retrieval via a medical thesaurus. We analyzed the deficiencies of the existing medical thesauri and reconstructed a new thesaurus, called MEDTHES, which follows the ANSI/NISO Z39.19-2003 standard. MEDTHES also endows the users with fine-grained control of information retrieval by providing functions to calculate the semantic similarity between words. We demonstrate the usage of MEDTHES through an existing data search engine.
