The theory of argumentation is a rich, interdisciplinary area of research straddling the fields of artificial intelligence, philosophy, communication studies, linguistics, and psychology. In the last years, significant progress has been made in understanding the theoretical properties of different argumentation logics. However, one major barrier to the(More)
This roadmap has been prepared as part of the activities of AgentLink III, the European Coordination Action for Agent-Based Computing (IST-FP6-002006CA). It is a collaborative effort, involving numerous contributors listed at the end of the report. We are grateful to all who contributed, including those not named. Neither the editors, authors, contributors,(More)
This document describes a strawman specification for an Argument Interchange Format (AIF) that might be used for data exchange between Argumentation tools or communication in Multi-Agent Systems (MAS). The document started life as a skeleton for contributions from participants in the Technical Forum Group meeting in Budapest in September 2005, receiving(More)
People are increasingly cooperating to share electronic information and techniques throughout various industries. In healthcare applications, data (a single patient's healthcare history), workflow (procedures carried out on that patient), and logs (a recording of meaningful procedural events) are often distributed among several heterogeneous and autonomous(More)

The integration of Semantic Web and Web Services technologies promises to be one of the most promising new areas for development of Intelligent Web Applications. One challenging area where these technologies meet is in explicit definitions of meaning for the messages exchanged between Web Services - in other words, semantic definitions of the meanings(More)
Approaches to computer game playing based on (typically α−β) search of the tree of possible move sequences combined with an evaluation function have been successful for many games, notably Chess. For games with large search spaces and complex positions, such as Go, these approaches are less successful and we are led to seek alternative approaches. One such(More)

File sharing networks are among the most popular applications of Peer-to-Peer (P2P) technology to date [3] and have been widely studied in terms of the performance, behavior, topology and other properties. A persistent theme throughout this research has been the evidence that many P2P file sharing systems rely on the presence of altruistic users, who(More)
