摘要

我们演示了BioNav系统，一个新的生物医学数据库搜索界面，如PubMed。BioNav使用户能够通过MeSH对大量查询结果进行分类;PubMed使用的综合概念层次结构。一旦查询结果被组织到导航树中，BioNav在每一步中只显示概念节点的一小部分，选择这些节点是为了使预期的用户导航成本最小化。相比之下，以前的工作以预定义的静态方式扩展层次结构，没有导航成本建模。BioNav可在http://db.cse.buffalo.edu/bionav上获得。

Exploring biomedical databases with BioNav

We demonstrate the BioNav system, a novel search interface for biomedical databases, such as PubMed. BioNav enables users to navigate large number of query results by categorizing them using MeSH; a comprehensive concept hierarchy used by PubMed. Once the query results are organized into a navigation tree, BioNav reveals only a small subset of the concept nodes at each step, selected such that the expected user navigation cost is minimized. In contrast, previous works expand the hierarchy in a predefined static manner, without navigation cost modeling. BioNav is available at http://db.cse.buffalo.edu/bionav.
