Agent technology has recently become one of the most vibrant and fastest growing areas in information technology. Within this booming area, intelligent information agents are attracting particular attention from the research and development community as well as from industry and user communities interested in everyday private and professional applications. This monographic text is the first systematic state-of-the-art survey on intelligent information agents. Eighteen coherently written chapters by leading authorities provide complementary coverage of the relevant issues organized in four parts: cooperative information systems and agents; rational information agents and electronic commerce; adaptive information agents; mobile agents and security. In addition, the volume editor has provided a detailed introductory survey chapter, motivational introductions to the four parts, and a comprehensive bibliography listing more than 700 entries.

As today's most complex computing environment, the Internet confronts IT researchers, system designers, and application developers with completely new challenges and, as a fascinating new computing paradigm, agent technology has recently attracted broad interest and strong hopes for shaping the future information society. Relating both, the Internet and agents, opens up a whole new range of advanced applications in vibrant subfields of information technology such as middleware, mobile commerce, e-learning, collaborative working, and intelligent information services. Many modern advanced systems are likely to exploit Internet agents - and exploiting Internet agents mostly means dealing with coordination models and technologies of various sorts. This monograph-like anthology is the first systematic guide to models and enabling technologies for the coordination of intelligent agents on the Internet and respective applications.

These are the proceedings of the 12th international workshop on cooperative informationagents(CIA2008), heldattheCzechTechnicalUniversityinPrague, Czech Republic, on September 10-12, 2008. In today's world of ubiquitously connected heterogeneous information s- tems, business services and computing devices, the intelligent coordination and provisionofrelevantadded-value informationor servicesto the user atany time, anywhere is of key importance to a variety of applications. This challenge is - visioned to be coped with by means of appropriate intelligent and cooperative information agents. An intelligent information agent is a computational software entity that is capable of accessing one or multiple, potentially heterogeneous and distributed information sources, proactively acquiring, mediating, and maintaining relevant information or services on behalf of its human users, or other agents, preferably just in time and anywhere. One key challenge of developing intelligent and - operative information systems is to balance the autonomy of networked data, information, and knowledge sourceswith the potential payo?of leveragingthem by the appropriate use of such agents.

The globaltrendtowardsmore?exible anddynamic businessprocessintegration and automation has led to a convergence of interests between service-oriented computing, semantic technology, and intelligent multiagent systems. In parti- lar the areas of service-oriented computing and semantic technology o?er much interestto the multiagentsystemcommunity, including similaritiesin system- chitectures and provision processes, powerful tools, and the focus on issues such as quality of service, security, and reliability. Similarly, techniques developed in themultiagentsystemsandsemantictechnologypromisetohaveastrongimpact on the fast-growing service-oriented computing technology. Service-oriented computing has emerged as an established paradigm for d- tributed computing and e-business processing. It utilizes services as fundam- tal building blocks to enable the development of agile networks of collaborating business applications distributed within and across organizational boundaries. Services are self-contained, platform-independent software components that can be described, published, discovered, orchestrated, and deployed for the purpose of developing distributed applications across large heterogeneous networks such as the Internet. Multiagent systems are also aimed at the development of distributed - plications, however, from a di?erent but complementary perspective. Servi- oriented paradigmsaremainly focused on syntacticaland declarativede?nitions of software components, their interfaces, communication channels, and ca- bilities with the aim of creating interoperable and reliable infrastructures. In contrast, multiagent systems center on the development of reasoning and pl- ning capabilities of autonomous problem solvers that apply behavioral concepts such as interaction, collaboration, or negotiation in order to create ?exible and fault-tolerant distributed systems for dynamic and uncertain environments

After two successful MATES conferences in Erfurt 2003 and 2004, the 3rd G- man conference on Multi-agent System Technologies (MATES 2005) took place in Koblenz, Germany, in September 2005, and was co-located with the 28th German Conference on Arti?cial Intelligence (KI 2005). Building onotheragent-relatedeventsinGermanyinthepast, andorganized by the GI German Special Interest Group on Distributed Arti?cial Intelligence, the MATES conference series aims at promoting the theory and applications of agentsandmultiagentsystems.Incorporatingthe9thInternationalWorkshopon Cooperative Information Agents (CIA 2005), the topics of interest for MATES 2005 also covered the ?elds of intelligent information agents and systems for the Internet and the (Semantic) Web. As in recent years, MATES 2005 provided a distinguished, lively and int- disciplinary forum for researchers, users, and developers of agent technology, to present and discuss the latest advances of research and development in the area of autonomous agents and multiagent systems. Accordingly, the topics of MATES 2005 covered the whole range from the theory to applications of age- and multiagent technology. The technical program included a total of 24 sci- ti?c talks, and demonstrations of selected running agent systems, and both the MATES 2005 Best Paper and the CIA 2005 System Innovation awards

This book introduces major agent platforms, frameworks, systems, tools, and applications. Each system is described by their developers in sufficient detail so that the reader can get a good understanding of the architecture, functionality, and application areas of the system. All systems are running systems. One main focus of the book lies on agent platforms and toolkits. They form the basis for the development of agent-based systems, thus, are a convenient starting point for everybody who wants to apply agent technology. Another focus lies on agent-based applications. These systems prove that agent technology is mature enough to permit the development of sophisticated applications, like electronic marketplaces, environments for computer-supported cooperative work, or transportation systems.

These are the proceedings of the 8th International Workshop on Cooperative Information Agents (CIA 2004), held at the Fair and Congress Center in - furt, Germany, September 27-29, 2004. It was part of the multi-conference Net. ObjectDays 2004, and, in particular, was co-located with the 2nd German Conference on Multiagent Systems Technologies (MATES 2004). In today's networked world of linked heterogeneous, pervasive computer systems, devices, and information landscapes, the intelligent coordination and provision of relevant added-value information at any time, anywhere, by means of cooperative information agents becomes increasingly important for a variety of applications. An information agent is a computational software entity that has access to one or multiple, heterogeneous, and geographically dispersed data and information sources. It proactively searches for and maintains information on behalf of its human users, or other agents, preferably just in time. In other words, itismanagingandovercomingthedi?cultiesassociatedwithinformation overload in open, pervasive information and service landscapes. Cooperative - formation agents may collaborate with each other to accomplish both individual and shared joint goals depending on the actual preferences of their users, b- getary constraints, and resources available. One major challenge of developing agent-based intelligent information systems in open environments is to balance the autonomy of networked data, information, and knowledge sources with the potential payo? of leveraging them using information agents.

These are the proceedings of the Fifth International Workshop on Cooperative Information Agents, held in Modena, Italy, September 6-8, 2001. Information agent technology has become one of the major key technologies for the Internet and the World Wide Web. It mainly emerged as a response to the challenges of cyberspace from both the technological and human user perspective. Development of information agents requires expertise from di?erent research disciplines such as Arti?cial Intelligence (AI), advanced databases and knowledge base systems, distributed information systems, information retrieval, and Human Computer Interaction (HCI). The ?fth international workshop on Cooperative Information Agents (CIA) continued the tradition by capturing the intrinsic interdisciplinary nature of the above research area by calling for contributions from di?erent research communities, and by promoting open and informative discussions on all related topics. In keeping with tradition, the workshop featured a sequence of regular and invited talks of excellence given by leading experts in the ?eld. This year the topics of the talks are mainly on the challenges of information agents in the upcoming age of ubiquitous and pervasive computing. These challenges are in particular due to the necessity of an e?cient utilization, evolution, and trust management of information agents for user-oriented information search, pro- sion, and visualization in networked computing environments with small, mobile, and embedded devices. A di?erent issue concerns the potential of agent-based support of massive distributed data warehousing worldwide.

These arethe proceedingsof the Fourth InternationalWorkshopon Cooperative Information Agents, held in Boston Massachusetts, USA, July 7-9, 2000. Cooperative information agent research and development focused originally onaccessingmultiple, heterogeneous, anddistributedinformationsources. Ga- ingaccesstothesesystems, throughInternetsearchengines, applicationprogram interfaces, wrappers, and web-based screens has been an important focus of - operative intelligent agents. Research has also focused on the integration of this information into a coherent model that combined data and knowledge from the multiple sources. Finally, this information is disseminated to a wide audience, giving rise to issues such as data quality, information pedigree, source reliability, information security, personal privacy, and information value. Research in - operative information agents has expanded to include agent negotiation, agent communities, agent mobility, as well as agent collaboration for information d- covery in constrained environments. TheinterdisciplinaryCIAworkshopseriesencompassesa widevarietyoft- ics dealing with cooperative information agents. All workshop proceedings have been published by Springer as Lecture Notes in Arti?cial Intelligence, Volumes 1202 (1997), 1435 (1998), and 1652 (1999), respectively. This year, the theme of the CIA workshop was The Future of Information Agents in Cyberspace, a very ?tting topic as the use of agents for information gathering, negotiation, correlation, fusion, and dissemination becomes ever more prevalent. We noted a marked trend in CIA 2000 towards addressing issues related to communities of agents that: (1) negotiate for information resources, (2) build robust ontologies to enhance search capabilities, (3) communicate for planning and problem so- ing, (4) learn and evolve based on their experiences, and (5) assume increasing degrees of autonomy in the control of complex systems."
