A knowledge elicitation study for collaborative dialogue strategies used to handle uncertainties in speech communication while using GIS

Existing speech enabled Geographical Information Systems (GIS) needs to have capabilities to handle uncertainties that are inherent in natural language communication. The system must have an appropriate knowledge base to hold such capabilities so that it can effectively handle various uncertainty problems in speech communication. The goal of this study is to collect knowledge about how humans use collaborative dialogues to solve various uncertainty problems while using GIS. This paper describes a knowledge elicitation study that we designed and conducted toward this goal. The knowledge collected can be used to develop the knowledge base of a speech enabled GIS or other speech based information systems.
