This paper describes AQUA (A QUery Analyzer), the natural language front end of a prototype information retrieval system. AQUA translates a user's natural language query into a representation in the Conceptual Graph formalism. The graph is then used by subsequent components to search various resources such as databases of the medical literature. The focus of the parsing method is on semantics rather than syntax, with semantic restrictions being provided by the UMLS Semantic Net. The intent of the approach is to provide a method that can be emulated easily in applications that require simple natural language interfaces.
本文介绍了AQUA（一种查询分析器），它是一个原型信息检索系统的自然语言前端。AQUA将用户的自然语言查询转换为概念图形式的表示。然后，后续组件使用该图来搜索各种资源，如医学文献数据库。解析方法的重点是语义而非句法，语义限制由统一医学语言系统（UMLS）语义网提供。该方法的目的是提供一种在需要简单自然语言接口的应用程序中易于模仿的方法。
