  1. SAGE and Its Application to Inter-company EC Ryusuke Masuoka NetMedia Laboratory Fujitsu Laboratories Ltd.

  2. Outline • ＳＡＧＥ and Facilitators • Functions of Facilitators • Implementation • Internal Workings • Experiments and Performance • Latest Developments

  3. SAGE Project • Smart Agent Environment for software agents: Agents communicate in ACL (Agent Communication Language) • Integrates information from disperse and/or legacy data sources through agentification • Facilitator helps interoperation between agents through translation, brokerage, and other services

  4. Applications • Inter-company EC • Consumer EC (Virtual Mall) • Online databases integration • Knowledge Management

  5. SAGE：Francis • An application of virtual catalogs to inter-company EC • Next step for “WitWeb,” an inter-company EC service • To deal with multiple servers • Recycling legacy product databases • Wrapping them into agents

  7. Functions of Facilitators (1) • Delegation based on: • (Un) Advertisement • Category • Agent capability • Range • Keyword Database • User Authentication • Partial Solution by facilitators

  8. Functions of Facilitators (2) • Message handling • Waiting and merging • Post Processes (sorting and limiting) • Ontology translation • Tool planned for translation info creation

  14. Translation Information (translation 'standard.database.kif 'fukuoka.database.kif (sentence-translation '(Item-name ?x ?value) '(Commodity_name ?x ?value) )) (translation 'standard.database.kif 'fukuoka.database.kif (sentence-translation '(Ctgry-code ?x "(Apple)0100020002") '(Ctgry-code ?x "1106003310523012") ))

  15. Translation (and (Ctgry-name ?x ?Ctgry-name) (Ctgry-code ?x "(Apple)0100020002") (Item-name ?x ?Item-name) (Price ?x ?Price) (and (>= ?Price 1000) (=< ?Price 3000))) (and (Ctgry-name ?x ?Ctgry-name) (Ctgry-code ?x "1106003310523012") (Commodity_name ?x ?Item-name) (Price ?x ?Price) (and (>= ?Price 1000) (=< ?Price 3000)))

  19. Performance

  20. Latest Developments • Adopted an inference engine • Multi-module, multi-thread safe, cache • Functions of Facilitators implemented • Unadvertise • User Authentication • Keyword Database • Partial Solution • Sorting and limiting

  21. Summary • We have implemented an inter-company EC prototype system based on SAGE, which will be ready for deployment next April.
