A difficulty in using knowledge-based systems has been linking them to clinical databases. The challenge is in making a correct mapping from the data in the knowledge base to the data in the database. At Columbia-Presbyterian Medical Center, we have built a suite of tools developed to create queries that address this challenge. The tools were designed to allow users to easily retrieve data from the database without requiring the users have extensive database and vocabulary knowledge. The tools help users write correct queries (Query Builder), find correct terms in the clinical database (MED Browser), aggregate the resulting data into a useful form (Clinical Database Browser), and allow the user to test the query within the environment of the knowledge-based system (Event Playback). The tools have been in use for one year.
使用基于知识的系统的一个困难在于将它们与临床数据库相连接。挑战在于从知识库中的数据到数据库中的数据进行正确的映射。在哥伦比亚长老会医学中心，我们构建了一套工具，用于创建应对这一挑战的查询。这些工具旨在让用户无需具备广泛的数据库和词汇知识就能轻松从数据库中检索数据。这些工具帮助用户编写正确的查询（查询构建器），在临床数据库中查找正确的术语（医学浏览器），将所得数据汇总成有用的形式（临床数据库浏览器），并允许用户在基于知识的系统环境中测试查询（事件回放）。这些工具已经使用了一年。
