LUKE: An Experiment In The Early Integration Of Natural Language Processing

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 to concurrently debug the application and the natural language interface. Luke also makes natural language available in its own user interface. This makes it possible for a knowledge base builder to exploit natural language both as a way of locating desired concepts within the knowledge base and as a a way of doing consistency checking on the knowledge base as it is being built. base, Luke makes natural language available in its own interface. This makes it possible for the knowledge base builder to exploit natural language both as a way of referring to objects in the knowledge base and as a way of doing consistency checking on the objects themselves. In this paper, we will describe both what Luke does and how doing that supports this productive view of the interaction between building a knowledge based system and building an associated natural language interface.
