    • An information retrieval system with good human-interface methods to give the system ease-of-use having two distinctive features with the first being visual interface and the second being natural language interpretation. The visual interface provides for visual interaction for local search and natural language interpretation provides for linguistic interaction for global search. The visual interface provides versatile views onto the contents of the knowledge base that the system has, controlling mechanisms for browsing through the knowledge base, a capability of showing relevant information for the users, and a mechanism for editing a query expression that describes information to retrieve. By using the visual interface for information retrieval, the users can easily create query expressions, by consulting and reacting with the system. The natural language interpretation makes use of a conceptual network as a knowledge-base that stores important concepts and relationships among these concepts. Based on knowledge and information represented in the conceptual network, the meaning of a noun phrase or a nominal compound which is a string of adjectives and nouns with some prepositions can be inferred. The inferred interpretation of such a noun phrase is paraphrased into an expression that the information retrieval system can handle. Therefore, the user of the system can simply describe the desired information in a language to get the desired information.
    • 一种具有良好人机界面方法的信息检索系统,使系统易用性具有两个独特的特征,第一个是视觉界面,第二个是自然语言解释。 视觉界面提供用于本地搜索的视觉交互,并且自然语言解释为全球搜索提供语言交互。 视觉界面提供了系统具有的知识库内容的多种视图,控制浏览知识库的机制,显示用户相关信息的能力,以及编辑描述要检索的信息的查询表达式的机制 。 通过使用可视化界面进行信息检索,用户可以通过与系统进行协商和反应,轻松创建查询表达式。 自然语言解释使用概念网络作为存储这些概念之间的重要概念和关系的知识库。 基于概念网络中所代表的知识和信息,可以推断名词短语或名词复合词的含义,它是具有一些介词的形容词和名词串。 这种名词短语的推断解释被转换成信息检索系统可以处理的表达式。 因此,系统的用户可以简单地用语言描述期望的信息以获得期望的信息。
