چکیده

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. This value is determined by the value of the information with respect to the decision being made, the responsiveness of the information source, and a time cost function specified by the user. We describe the benefits of the system and the lessons learned from its development.

Value-Driven Information Gathering

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 ...

An Efficient Network Information Model Using NWS for Grid Computing Environments

Grid computing technologies enable large-scale aggregation and sharing of resources via wide-area networks focused on sharing computational, data, and other resources to form general-purpose services for users. In this paper, we address network information gathering and focus on providing approximate measurement models for network-related information using Network Weather Service (NWS) for futu...

From 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...
