Collaborative environments, where multiple heterogeneous agents (managing several resources) can coop- erate in pursuing common and individual goals, are a step forward in creating real-world agent societies. However, current research in agent negotiation and in service coordination is still not enough for building such an agent-based society, capable of jointly solving complex planning problems a...<br/><br/>António Luís Lopes, Luís Miguel Botelho (2010) <i>2nd International Conference on Agents and Artificial Intelligence</i> <br/>

The distributed nature of peer-to-peer networks offers a solid ground for the deployment of environments where multiple agents, managing several resources, can cooperate in pursuing common and individual goals while achieving good overall performance. In this article we present a survey of recent work on the integration of multi-agent systems and peer-to-peer computing for resource coordinatio...<br/><br/>António Luís Lopes, Luís Miguel Botelho (2008) <i>Journal of Networks</i> 3: (2) 38-47<br/>

A semantic overlay network is a powerful mechanism for collaborative environments where multiple agents, managing several resources, can cooperate in pursuing common and individual goals while achieving good overall performance. However, building such a social structure dynamically from an unstructured peer-to-peer network is a lengthy process if appropriate algorithms and techniques are not used....<br/><br/>António Lopes, Luís Botelho (2008) <i>Seventh International Workshop on Agents and Peer to Peer Computing</i> 1-15<br/>

The need to add semantic information to web-accessible services has created a growing research activity in this area. Standard initiatives such as OWL-S and WSDL enable the automation of discovery, composition and execution of semantic web services, i.e. they create a Semantic Web, such that computer programs or agents can implement an open, reliable, large-scale dynamic network of Web Services.

This paper describes the initial PhD research work for developing an innovative process for agent coordination in unstructured distributed environments. In this proposal, an agent that receives a request will use an AI-based planning algorithm to decompose the received request into several subtasks; it will handle those for which it has know-how and available resources; and it will use decentraliz...<br/><br/>António Luís Lopes, Luís Miguel Botelho (2007) <i>International Conference on Complex, Intelligent and Software Intensive Systems</i> 209-214<br/>

This paper proposes to use cognitive multi-agent based simulation to facilitate human team formation decision processes. The models of organizational actors are acquired by a data-gathering monitoring system that stores all the interactions that take place in the selected cooperative task. In this knowledge acquisition process, only a relatively small number of team compositions are monitored.

This paper describes Chomsky, a content language translation agent. This agent provides a service, which first translates the content expression from its original language into an abstract logic language (ALL). Then, the resulting ALL expression is translated to the desired target language. ALL has been designed as a superset of most known content languages to avoid loosing expressiveness during t...<br/><br/>António Luís Lopes, Luís Miguel Botelho (2005) <i>LNCS 3690: Multi-Agent Systems and Applications IV</i> 535-538<br/>
