Web2Agent project IKTA4-121/2001 May 22 nd Project objectives Technology: Development of an interface technology and methodology to make Internet information resources accessible through FIPA-compliant agent interface. Prototype: Development of a library agent service. Strategy: Contribute to the establishment of the Agentcities network.

Web2Agent project IKTA4-121/2001 May 22 nd What is an agent? Agent: problem-solving unit, perceives and changes its environment, achieves goals, autonomous, proactively adapts to its environment Also a new systems design paradigm: complex distributed systems object oriented  agent oriented Semantic web, Web Services, GRID

Web2Agent project IKTA4-121/2001 May 22 nd What is the role of this IKTA4 project in this? The project’s own objectives methodology for interface technology, development of tools, prototype application Integrated project (FP5, FP6) national project - EU project – Agentcities Task Force Dissemination of the technology on national level project partners Connecting to W3C’s work agents and web services working group

Web2Agent project IKTA4-121/2001 May 22 nd Phases of the project Setup agent platform setting up agent environment, assessment of application requirements, design of the functionality of the prototype application, deliverables: technical document and an operating platform Elaborate technology and methodology FIPA standards, agent wrapper, deliverable: system plan serving as a technology guide Prototype system library application, testing of interface technology, deliverable: prototype system
