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.
