本文描述了一个口语对话系统中的对话管理器及其与语义和上下文跟踪的交互，该系统是为一般信息检索和事务处理应用而开发的。对话系统支持以下基本功能：电子表格填写、数据库查询、结果导航、属性-值对引用以及值和引用解析。提出了一种通用的数据结构和算法，用于表示和解决口语对话系统中的歧义，并为所有依赖于应用程序的语义和对话信息提出了一个简约的parsimoniousparameterizationfor。对话管理算法检查语义和对话状态，并适应用户的需求和任务的必要性。这些算法被应用到一个旅行预订的DARPA的项目下开发的应用程序。所提出的算法是独立于应用程序的，并通过仅改变原型树中编码的语义和由解析器和提示生成器等组件使用的域相关项板来方便开发新的口语对话系统。
This paper describes a dialogue manager and its interaction with semantics and context tracking in a spoken dialogue system developed for general information retrieval and trans- action applications. The dialogue system supports the fol-lowing basic functionality: electronic form filling, database query, result navigation, attribute-value pair referencing, and value and reference resolution. General data structures and algorithms for representing and resolving ambiguity in a spoken dialogue system and a parsimoniousparameterizationfor all application-dependent semantic and dialogue information are proposed. Dialogue management algorithms examine the semantics and dialogue state and adapt to the user’s needs and task necessities. These algorithms are applied to a travel reservation application developed under the auspices of the DARPA Communicator project. The proposed algorithms are application-independent and facilitate ease of developing new spoken dialogue systems by changing only the semantics encodedin the prototype tree and the domain-dependenttem-plates used by such components as the parser and the prompt generator.
