Abstract

This paper presents a system for autonomous informationgathering in an information rich domain under time and monetaryresource restrictions. The system gathers information using anexplicit representation of the user's decision model and adatabase of information sources. Information gathering isperformed by repeatedly selecting the query with the highestmarginal value. This value is determined by the value of theinformation with respect to the decision being made, theresponsiveness of the information source, and a given resourcecost function. Finally, we compare the value-driven approach toseveral base-line techniques and show that the overhead of themeta-level control is made up for by the increased decisionquality.
