A Value-driven System for Scheduling Information Gathering a Value-driven System for Scheduling Information Gathering
This paper presents a system for scheduling information gathering in an information rich domain under time and monetary resource restrictions. The system gathers information using an explicit representation of the user's decision model and a database of information sources. Information gathering actions (queries) are scheduled myopically by selecting the query with the highest marginal value. T...

We describe a decision-theoretic approach to information gathering from a distributed network of information sources. Our approach uses an explicit representation of the user’s decision model in order to plan and execute information gathering actions. The information gathering planner issues requests based on the value of information taking into account the computational resources and monetary ...

متن کاملFrom HTML to usable data Problems in meaning and credibility in the WWW
This paper describes issues in information integration that relate to Value-Driven Information Gathering (VDIG)(Grass & Zilberstein 1996; 1997; 1998). Valuedriven information gathering is the process of querying multiple information sources for information items which are used to make a decision. VDIG works in a resource-bounded environment where it is not possible to gather all the information...
