Title: Integrating Web Resources into the Agentcities Multi-agent initiative of the EU


1
Integrating Web Resources into the Agentcities
Multi-agent initiative of the EU
  • Presenter
  • László Zsolt Varga
  • Computer and Automation Research InstituteMTA
    SZTAKI
  • Hungary

2
Project Members
  • MTA SZTAKI
  • Széchényi National Library
  • T-Systems Dataware Ltd.
  • AITIA Inc.

3
Project objectives
  • TechnologyDevelopment of an interface
    technology and methodology to make Internet
    information resources accessible through
    FIPA-compliant agent interface.
  • PrototypeDevelopment of a library agent
    service.
  • Strategy
  • Contribute to the establishment of the
    Agentcities network.

4
What is an agent?
  • Agentproblem-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

5
What is FIPA?
  • FIPA Foundation for Intelligent Physical Agents
  • International organization registered in Geneva
    (1996)
  • Aims at the development of software standards for
    interoperable heterogeneous agents and agent
    based systems
  • Members key multinational IT companies, telecom
    companies, important universities and research
    institutes
  • Four meetings annually

6
What is Agentcities?
  • Global initiative to create a world wide network
    for agent based services
  • Composition of dynamic, intelligent and
    autonomous services
  • Agent technology, Semantic Web, UDDI service
    repository, eBusiness standards, GRID
  • Distributed testbed
  • EU FP5 project, pattern for EU FP6 Integrated
    Projects

What is Agentcities? (2)
8
What is the role of this IKTA4 project in this?
  • The projects 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 W3Cs work
  • agents and web services working group

9
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 systemlibrary application, testing of
    interface technology, deliverable prototype
    system

10
Steps of the implementation of the library agent
  • Selection of interface towards the existing
    system
  • Ontology design and specification
  • Ontology code (RDF, DAMLOIL, Java)
  • Implementation of the wrapper
  • Implementation of agent logic
  • Testing the prototype system
  • Integration with other agent services

11
Selection of the interface
Libraryapplication
GUI
  • No digging in the UI
  • No direct data access
  • Utilise existing application logic

?
Html (web)
?
!
Z39.50 server
?
Web service?
12
Ontology design
  • Concepts from
  • real life scenario (detail)
  • protocol specification (simplify)
  • value added services (define)
  • Formats
  • FIPA spec-like document
  • Protégé project
  • RDFS, HTML, Java code

13
Methodology Architecture
Code intelligence
Extend ontology
Web service
Wrapper agent
FIPA ACL
Agent combined service
Client agent
SOAP
FIPA ACL
Web service
Wrapper agent
GUI
Generate wrapper ontology
Generate SOAP call
Generate test client (for the wrapper)
WSDL
14
Summary (Results up to now)
  • Setting up Budapest platform (one of the most
    stable ones)
  • Budapest Library Agent Ontology
  • Elaboration of the principles of the methodology
  • Code generators supporting the methodology
  • Skeleton of the prototype application
  • Presence at AAMAS 2002 conference
  • Active member of the Agentcities.NET project
  • W3C Autonomous Web Services Interest Group seed
