In tackling data mining and pattern recognition tasks, finding a compact but effective set of features has often been found to be a crucial step in the overall problem-solving process. In this paper we present an empirical ...

Rapid changes in the business environment call for more flexible and adaptive workflow systems. Researchers have proposed that Workflow Management Systems (WfMSs) comprising multiple agents can provide these capabilities. ...

Norms are shared expectations of behaviours that exist in human societies. Norms help societies by increasing the predictability of individual behaviours and by improving co-operation and collaboration among members. Norms ...

An area where multi-agent systems can be put to effective use is for the case of an open collection of autonomous problem solvers in a dynamically changing environment. One example of such a situation is that of environmental ...

An architecture, and the accompanying infrastructural support, for agent-based software developement is described which supports the use of agent-oriented ideas at multiple levels of abstraction. At the lowest level are ...

We present an empirical study on classical music instrument classification. A methodology with feature extraction and evaluation is proposed and assessed with a number of experiments, whose final stage is to detect instruments ...

This paper proposes a rule language for defining social expectations based on a metric interval temporal logic with past and future modalities and a current time binding operator. An algorithm for run-time monitoring ...

This paper proposes the use of the Unified Modelling Language (UML) as a formalism for defining an abstract syntax for Agent Communication Languages (ACLs) and their associated content languages. It describes an approach ...

Online virtual worlds such as Second Life provide a rich medium for unstructured human interaction in a shared simulated 3D environment. However, many human interactions take place in a structured social context where ...

Ontologies play an important role in defining the terminology that agents use in the exchange of knowledge-level messages. As object-oriented modelling, and the Unified Modeling Language (UML) in particular, have built up ...
