This book constitutes the thoroughly refereed post-workshop proceedings of the 8th International Workshop on Agents and Data Mining Interaction, ADMI 2012, held in Valencia, Spain, in June 2012. The 16 revised full papers were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on agents for data mining, data mining for agents, and agent mining applications.

Peer-to-peer (P2P) computing is currently attracting enormous public attention, spurred by the popularity of file-sharing systems such as Napster, Gnutella, Morpheus, Kaza, and several others. In P2P systems, a very large number of autonomous computing nodes, the peers, rely on each other for services. P2P networks are emerging as a new distributed computing paradigm because of their potential to harness the computing power and the storage capacity of the hosts composing the network, and because they realize a completely open decentralized environment where everybody can join in autonomously. Although researchers working on distributed computing, multiagent systems, databases, and networks have been using similar concepts for a long time, it is only recently that papers motivated by the current P2P paradigm have started appearing in high quality conferences and workshops. In particular, research on agent systems appears to be most relevant because multiagent systems have always been thought of as networks of autonomous peers since their inception. Agents, which can be superimposed on the P2P architecture, embody the description of task environments, decision-support capabilities, social behaviors, trust and reputation, and interaction protocols among peers. The emphasis on decentralization, autonomy, ease, and speed of growth that gives P2P its advantages also leads to significant potential problems. Most prominent among these are coordination the ability of an agent to make decisions on its own actions in the context of activities of other agents, and scalability the value of the P2P systems in how well they self-organize so as to scale along several dimensions, including complexity, heterogeneity of peers, robustness, traffic redistribution, etc.

This book brings together an introduction, three invited articles, and revised versions of the papers presented at the Second International Workshop on Agents and Peer-to-Peer Computing, AP2PC 2003, held in Melbourne, Australia, July 2003."

The leading edge of computer science research is notoriously ?ckle. New trends come and go with alarming and unfailing regularity. In such a rapidly changing ?eld, the fact that research interest in a subject lasts more than a year is worthy of note. The fact that, after ?ve years, interest not only remains, but actually continues to grow is highly unusual. As 1998 marked the ?fth birthday of the International Workshop on Agent Theories, Architectures, and Languages (ATAL), it seemed appropriate for the organizers of the original workshop to comment on this remarkable growth, and re ect on how the ?eld has developed and matured. The ?rst ATAL workshop was co-located with the Eleventh European Conference on Arti?cial Intelligence (ECAI-94), which was held in Amsterdam. The fact that we chose an AI conference to co-locate with is telling: at that time, we expected most researchers with an interest in agents to come from the AI community. The workshop, whichwasplannedoverthesummerof1993, attracted32submissions, andwasattended by 55 people.ATAL was the largest workshop at ECAI-94, and the clear enthusiasm on behalfofthecommunitymadethedecisiontoholdanotherATALworkshopsimple.The ATAL-94proceedingswereformallypublishedinJanuary1995underthetitleIntelligent Agents, and included an extensive review article, a glossary, a list of key agent systems, and - unusually for the proceedings of an academic workshop - a full subject index.

This carefully edited book constitutes the strictly refereed post-workshop proceedings of the 4th International Workshop on Agent Theories, Architectures, and Languages, ATAL'97, held in Providence, Rhode Island, USA, in July 1997.
The 25 revised full papers presented were selected from a total of 76 submissions. The book is divided into sections on methodologies, architectures and infrastructures, coordination planning and monitoring, formal methods, theories, and architectures and methodologies. Like its predecessors published in the Intelligent Agents series, this volume specifically focuses on the relationships between the theory and the applications of agents.

This special issue is the result of the selection and re-submission of advanced and revised versions of papers from the workshop on "Trust in Agent Societies" (11th edition), held in Estoril (Portugal) on May 10, 2008 as part of the Autonomous Agents and Multi-Agent Systems 2008 Conference (AAMAS 2008), and organized by Rino Falcone, Suzanne Barber, Jordi Sabater-Mir, and Munindar Singh. The aim of the workshop was to bring together researchers from different fields (artificial intelligence, multi-agent systems, cognitive science, game theory, and social and organizational sciences) that could contribute to a better understanding of trust and reputation in agent societies. The workshop scope included theoretical results as well their applications in human-computer interaction and electronic commerce. It was constituted by a main session integrated with two others: the first on the formal models of trust, and the second on reputation models. In this volume we present papers from the three workshop sessions: the main s- sion with papers on theoretical and applicative aspects of trust (from a engineering, cognitive, computational, sociological point of view); the formal model session with works in the field of applied logic and applied mathematics; the reputation models session with papers that specifically address models of reputation systems, theo- driven and empirically backed-up guidelines for designing reputation technologies, and analysis and discussion of existing reputation systems.

The world of agents comprises a broad range of intelligent programs that perform specific tasks on behalf of their users. Agents are distinguished from other types of software by their status as independent entities capable of completing complex assignments without intervention, rather than as tools that must be manipulated by a user. Largely the province of speculation before the early 1990s, agent research has flourished since the advent of the Internet, which has created an ideal operating environment.
This important collection unifies the extensive recent literature on agent technology, presenting a wealth of the finest published papers on both theory and applications. Huhns and Singh have drawn on research communities in AI, databases, distributed computing, and programming languages to assemble the most comprehensive overview of the agent world available. The editors add a summary of the field and its terminology, history, and major issues, together with introductions to each of the thematic chapters and discussions of the significance and context of the individual papers.
Focuses on:
+ applications of agents
+ classical techniques for agent construction
+ theory for modeling and understanding agents
+ intellectual frontiers in agent science.
Researchers, practitioners, and students will gain the essential background and perspective needed to understand and appreciate current and future agent research.

The Practical Handbook of Internet Computing analyzes a broad array of technologies and concerns related to the Internet, including corporate intranets. Fresh and insightful articles by recognized experts address the key challenges facing Internet users, designers, integrators, and policymakers. In addition to discussing major applications, it also covers the architectures, enabling technologies, software utilities, and engineering techniques that are necessary to conduct distributed computing and take advantage of Web-based services. The Handbook provides practical advice based upon experience, standards, and theory. It examines all aspects of Internet computing in wide-area and enterprise settings, ranging from innovative applications to systems and utilities, enabling technologies, and engineering and management. Content includes articles that explore the components that make Internet computing work, including storage, servers, and other systems and utilities. Additional articles examine the technologies and structures that support the Internet, such as directory services, agents, and policies. The volume also discusses the multidimensional aspects of Internet applications, including mobility, collaboration, and pervasive computing. It concludes with an examination of the Internet as a holistic entity, with considerations of privacy and law combined with technical content.
