These are the proceedings of the 7th International Workshop on Cooperative Information Agents (CIA 2003), held at the Sonera Conference Center in H- sinki, Finland, August 27–29, 2003. It was co-located with the 4th Agentcities Information Days. One key challenge of developing advanced agent-based information systems is to balance the autonomy of networked data and knowledge sources with the pot- tial payo? of leveraging them by the appropriate use of intelligent information agents on the Internet. An information agent is a computational software entity thathasaccesstooneormultiple,heterogeneous,anddistributeddataandinf- mation sources; proactively searches for and maintains relevant information on behalfofitshumanusersorotheragents,preferablyjust-in-time. Inotherwords, it is managing and overcoming the di?culties associated with information ov- load in the open and exponentially growing Internet and Web. Depending on the application and tasks at hand information agents may collaborate in open, n- worked data and information environments to provide added value to a variety of applications in di?erent domains. Thus, research and development of inf- mation agents is inherently interdisciplinary: It requires expertise in information retrieval, arti?cial intelligence, database systems, human-computer interaction, and Internet and Web technology. Initiated in 1997, the purpose of the annual international workshop series on cooperativeinformationagents(CIA)istoprovideaninterdisciplinaryforumfor researchers, software developers, and managers to get informed about, present, anddiscussthelatesthigh-qualityresultsinadvancementsoftheoryandpractice in information agent technology for the Internet and Web. Each event of this renowned series attempts to capture theintrinsic interdisciplinary nature of this research area by calling for contributions from di?erent research communities, and by promoting open and informative discussions on all related topics.
