1. The UMBC TAGA Demo What we have developed and achieved –Travel Agent Game in Agentcities (TAGA) –A FIPA compliant agent framework that extends and enhances the Trading Agent Competition (TAC) –Project won the Best Student Entry in the Agentcities sponsored Agent Technology Competition held in Feb. 2003 in Barcelona Our main contributions –Auction services are developed to enrich the Agentcities environment –The use of Semantic Web languages (RDF & DAML+OIL) improves agent interoperability –DAML-S ontology is employed to support service registration, discovery and invocation.

2. The TAGA Game and Players Game Objective: develop strategies for different agents to achieve their objectives Human players can choose to implement/play agents with different objectives: Customer Agent (CA) (1)find travel arrangements (2)try to save $$ Travel Agent (TA) (1)satisfy customers’ needs (2)try to maximize profits Web Service Agent (WSA) (1)sell “goods” (e.g., plane tickets & hotel rooms) (2)try to maximize profits
