Barry Norton, Ontology-based Behavioural Semantics for Business Processes

We present the Business Process Modelling Ontology, developed in the SUPER project, and a Behavioural Reasoning Ontology which confers process algebraic behavioural semantics on processes via ontology-based rules. This is based on previous work on giving compositional process algebraic semantics to the OWL-S process model, which led to the Cashew process model developed in the DIP project. As there the emphasis is on judging behavioural equivalences; on-going work concerns making such judgements via ontology-based reasoning.

Monika Solanki, Imperial College London: Towards Verifying Compliance in Agent-based Web Service Compositions

We explore the problem of specification and verification of compliance in agent based Web service compositions. We use the formalism of temporal-epistemic logic suitably extended to deal with compliance/violations of contracts. We illustrate these concepts using a motivating example where behaviours of participating agents are governed by contracts. The composition is specified in OWL-S and mapped to our chosen formalism. Finally we use an existing symbolic model checker to verify the example specification whose state space is approx 2^21 and discuss the experimental results.

Narrative Hypermedia is...


Narrative Hypermedia
Narrative is concerned fundamentally with coherence, for instance, whether that be a fiction, an historical account or an argument, none of which 'make sense' unless they are put together in a coherent manner.

Hypermedia is the combination of hypertext for linking and structuring multimedia information.

Narrative Hypermedia is therefore concerned with how all of the above narrative forms, plus the many other diverse forms of discourse possible on the Web, can be effectively designed to communicate coherent conceptual structures, drawing inspiration from theories in narratology, semiotics, psycholinguistics and film.
