Decision Support Information Gathering System  Chiu-Che Tseng
and Piotr J. Gmytrasiewicz  The Decision Support Information
Gathering System, Digs, uses influence diagrams to model user’s
decisions and to calculate the value of imperfect information
for each available information source. The system then plans and
executes the information gathering process providing the most
valuable information to the user. Thus, the system saves time
and cost of, sometimes random, search for information performed
by using keyword search. Furthermore, it can suggest the proper
decision to the user based on the newly retrieved additional
information.
