A natural language query interface provides database retrieval facilities as an effective means for encouraging novice users to access computer database systems. This paper describes a natural language query processing technique in Korean interface for object-oriented databases which have recently started to emerge as the next-generation databases. This interface transforms Korean natural langu...

This paper describes an exploratory study peqormed to compare three different interface styles for ad hoc query to a database. Subjects with wide ranging computer experience performed queries of varying dificulty using either an artificial, a graphical, or a natural language interface. All three interfaces were commercial products. The study revealed strengths and weaknesses of each interface a...

Luke is a knowledge editor designed to support two tasks; the first is editing the classes and relations in a knowledge base. The second is editing and maintaining the semantic mapping knowledge neccesery to allow a natural language interface to understand sentences with respect to that knowledge base. In order to emphasize design decisions shared between the two tasks, Luke provides facilities...

In this paper we present a framework for creating natural language interfaces to action-based applications. Our framework uses a number of reusable application-independent components, in order to reduce the effort of creating a natural language interface for a given application. Using a type-logical grammar, we first translate natural language sentences into expressions in an extended higher-or...

This paper presents results from a refined analysis of a series of Wizard of Oz-experiments with focus on discourse management. The study is part of a larger project aimed at designing a general natural language interface. It is argued that a natural language interface needs different referent res­ olution mechanisms for different combinations of background systems and scenarios. I present thre...

Restrictions on the user interface (like using templateor menu-based communication ) could significantly ease the implementation but they constrain considerably the expressiveness, the flexibility and the applicability. Building free-form natural language communication with domain restrictions is also possible but it requires the application of very complex language tools (parsing, disambiguati...

Natural language interfaces to computers must deal with wide variation in real-world input. This paper proposes that, in order to handle real-world input robustly, a natural language interface should be constructed in accord with principles of integrated processing: processing syntax and semantics at the same time, processing syntax and semantics using the same mechanisms, and processing langua...
