In this paper we focus on the semantic heterogeneity problem as one of the main challenges
in current Spatial Data Infrastructures (SDIs). We first report on the state of the art in reducing …

The aim of 'programming the global computer'was identified by Milner and others as one of
the grand challenges of computing research. At the time this phrase was coined, it was …

A necessary feature of social networks is a model of interaction which is followed on the
network---some structure which coordinates activity between the participants. These …

As computer systems grow in size and complexity, their integration, while a necessity,
becomes more difficult. Service oriented architectures and middleware systems in general …

Abstract The Lightweight Coordination Calculus was presented in a paper to DALT 2004 as
a method for specifying a class of social norms for multi-agent systems. This was intended …

Web service composition is a difficult and important requirement for the success of the
Semantic Web. In this paper, we present a method of facilitating automated service …

Agents need to communicate in order to accomplish tasks that they are unable to perform
alone. Communication requires agents to share a common ontology, a strong assumption in …

The definition of choreography specification languages for Service Oriented Systems poses
important challenges. Mainstream approaches tend to focus on procedural aspects, leading …

Despite the fact that social computation systems involve interaction mechanisms that closely
resemble well-known models of agent coordination, current applications in this area make …

When we wish to coordinate complex, cooperative tasks in open multi-agent systems, where
each agent has autonomy and the agents have not been designed to work together, we …
