The 2004 IFIP International Conference on Intelligence in Communication S- tems(INTELLCOMM2004),heldinBangkok,Thailand,23–26November2004, was the successor and an expansion of SMARTNET, a series of annual conf- ences on intelligence in networks held during 1995–2003 under the auspices of IFIP TC6’s Working Group 6. 7. The Internet and Web provide more connection facilities, hence the man-man, man-machine and machine-machine interactions will increase and communication will have an important role in modern s- tems. Inordertoobtaine?ectiveande?cientcommunication,artistic,socialand technical issues have to be tackled in a holistic and integrated manner. However, communicationtechniques,conceptsandsolutionswhichhavebeendevelopedso far treat these issues separately, so that there arises a need for communication researchers and practitioners in di?erent ?elds (engineering, science and arts) to meet, share their experience and explore all possibilities of developing in- grated and advanced solutions which incorporate ideas from such disciplines as communication arts, art design, linguistics, Web technologies, computer system architecture and protocols, computer science and arti?cial intelligence. INTELLCOMM 2004 was jointly sponsored by IFIP WG 6. 7: Smart N- works and WG 6. 4: Internet Applications Engineering and aimed to provide an international forum which brings academia, researchers, practitioners and s- vice providers together. The discussion areas covered the latest research topics andadvancedtechnologicalsolutionsintheareaofintelligenceincommunication systems, ranging from architectures for adaptable networks/services and Sem- ticWeb/Webservicestechnologiestointelligentserviceapplicationinterfaceand intelligent human interaction. INTELLCOMM 2004received 112 paper submissions from 28 countries. From these, 24 were accepted, and are included in this proceedings. There were also 3 papers accepted for poster presentation, published separately.
