Title: From partner selection to collaboration in information sharing multi-agent systems
Author: Park, Jisun
Abstract: This research advances distributed information sharing by equipping nodes (e .g . , software agents ) in a distributed network with (1 ) partner selection algorithms in cooperative environments , and (2 ) strategies for providing and requesting information in competitive environments . In cooperative environments , information providers are willing to provide requested information , but information consumers must consider uncertainty in the quality of provided information when selecting appropriate information providers . In competitive environments , if a self -interested agent can be an information consumer and provider at the same time , agents need to determine the best ways to request and provide information so that the information acquisition utility can be maximized . This research defines a set of metrics for evaluating information acquisition utility , and presents a game -theoretic approach for determining the best information sharing strategies based on stochastic games . The results show how agents build collaborative relationships with appropriate agents and how the information acquisition utility is affected by those relationships .
