Agent metaphors and technologies are increasingly adopted to harness and g- ernthecomplexityoftoday'ssystems.Asaconsequence,thegrowingcomplexity of agent systems calls for models and technologies that promote system p- dictability and enable feature discovery and veri?cation. Formal methods and declarative technologies have recently attracted a growing interest as a means to address such issues. The aim of the DALT 2003 workshop was two-fold. On the one hand, we wanted to foster a discussion forum to export such techniques into the broader communityofagentresearchersandpractitioners.Ontheotherhand,wewanted to bring in the issues of real-world, complex, and possibly large-scale agent s- tem design in the perspective of formal methods and declarative technologies.Thanks to the very high quality of our program committee, we managed to put together a rich program, including three technical sessions and two panel sessions:TheUseofDeclarativeProgrammingforAgent-OrientedSoftwareEn- neering, moderated by Leon Sterling and Andrea Omicini, and Declarative and Logic-Based Technology for Agent Reasoning and Interactions, organized and moderated by Rafael Bordini and Wiebe van der Hoek, with the participation of ?ve invited panelists. This bookcontainstherevisedandextendedversionsofthe paperspresented at the workshop, as well as three invited contributions by leading researchers of the ?eld. It is composed of three parts: (i) software engineering and multi-agent system prototyping, (ii) agent reasoning, BDI logics and extensions, and (iii) social aspects of multi-agent systems.

Logics have, for many years, laid claim to providing a formal basis for the study and development of applications and systems in arti?cial intelligence. With the depth and maturity of formalisms, methodologies and logic-based systems - day, this claim is stronger than ever. The European Conference on Logics in Arti?cial Intelligence (or Journ' ees Europ' eennes sur la Logique en Intelligence Arti?cielle, JELIA) began back in 1988, as a workshop, in response to the need for a European forum for the discussion of emerging work in this ?eld. Since then, JELIA has been organized biennially, with English as its o?cial language, previous meetings taking place in Rosco?, France (1988), Amsterdam, Nether- ' lands (1990), Berlin, Germany (1992), York, UK (1994), Evora, Portugal (1996), Dagstuhl,Germany(1998),M' alaga,Spain(2000)andCosenza,Italy(2002). The increasinginterestinthisforum,itsinternationallevelwithgrowingparticipation from researchers outside Europe, and the overall technical quality have turned JELIA into a major biennial forum for the discussion of logic-based approaches to arti?cial intelligence.The 9th European Conference on Logics in AI, JELIA 2004, took place in Lisbon, Portugal, between the 27th and the 30th of September 2004, and was hosted by the Universidade Nova de Lisboa. Its technical program comprised 3 invited talks, by Francesca Rossi, Franz Baader, and Bernhard Nebel, and the presentationof52refereedtechnicalarticlesselectedbytheProgramCommittee among the 144 that were submitted, a number which in our opinion clearly indicates that the research area of logics in AI is one with a great and increasing interest.

Over recent years, the notion of agency has claimed a major role in de?ning the trends of modern research. In?uencing a broad spectrum of disciplines such as sociology, psychology, philosophy and many more, the agent paradigm virtually invaded every sub?eld of computer science, because of its promising applications for the Internet and in robotics. Multi-agent systems (MAS) are communities of problem-solving entities that can perceive and act upon their environments to achieve their individual goals as well as joint goals. The work on such systems integrates many technologies and concepts in arti?cial intelligence and other areas of computing. There is a full spectrum of MAS applications that have been and are being developed: from search engines to educational aids to electronic commerce and trade. Although commonly implemented by means of imperative languages, mainly for reasons of e?ciency, the agent concept has recently increased its in?uence in the research and development of computational logic-based systems. Computational logic, by virtue of its nature both in substance and method, providesawell-de?ned,general,andrigorousframeworkforsystematicallystu- ing computation, be it syntax, semantics, and procedures, or implementations, environments, tools, and standards. Computational logic approaches problems, and provides solutions, at a su?cient level of abstraction so that they generalize from problem domain to problem domain, a?orded by the nature of its very foundation in logic, both in substance and method, which constitutes one of its major assets.

The second edition of the workshop on Declarative Agent Languages and Te- nologies (DALT 2004) was held July 2004 in New York City, and was a great success. We saw a signi?cant increase in both the number of submitted papers and workshop attendees from the ?rst meeting, held July 2003 in Melbourne. Nearly 40 research groups worldwide were motivated to contribute to this event by submitting their most recent research achievements, covering a wide variety of the topics listed in the call for papers. More than 30 top researchers agreed to join the Program Committee, which then collectively faced the hard task of selecting the one-day event program. The fact that research in multi-agent systems is no longer only a novel and promising research horizon at dawn is, in our opinion, the main reason behind DALT’s (still short) success story. On the one hand, agent theories and app- cations are mature enough to model complex domains and scenarios, and to successfully address a wide range of multifaceted problems, thus creating the urge to make the best use of this expressive and versatile paradigm, and also pro?t from all the important results achieved so far. On the other hand, bui- ing multi-agent systems still calls for models and technologies that could ensure system predictability, accommodate ?exibility, heterogeneity and openness, and enable system veri?cation.

The notion of agency has recently increased its in?uence in the research and - velopment of computational logic based systems, while at the same time sign- cantly gaining from decades of research in computational logic. Computational logic provides a well-de?ned, general, and rigorous framework for studying s- tax, semantics and procedures, for implementations, environments, tools, and standards, facilitating the ever important link between speci?cation and ver- cation of computational systems. The purpose of the Computational Logic in Multi-agent Systems (CLIMA) international workshop series is to discuss techniques, based on computational logic, for representing, programming, and reasoning about multi-agent systems in a formal way. Former CLIMA editions were conducted in conjunction with other major computational logic and AI events such as CL in July 2000, ICLP in December 2001, FLoC in August 2002, and LPNMR and AI-Math in January 2004. The ?fth edition of CLIMA was held Lisbon, Portugal, in September 29–30, 2004.We,asorganizers,andinagreementwiththeCLIMASteeringCommittee, opted for co-location with the 9th European Conference on Logics in Arti?cial Intelligence (JELIA 2004), wishing to promote the CLIMA research topics in the broader community of logics in AI, a community whose growing interest in multi-agent issues has been demonstrated by the large number of agent-related papers submitted to recent editions of JELIA. The workshop received 35 submissions – a sensible increase from the previous edition.Thesubmittedpapersshowedthatthelogicalfoundationsofmulti-agent systems are felt by a large community to be a very important research topic, upon which classical AI and agent-related issues are to be addressed.
