3rd Joint WG Workshop - Session 1: Semantics, Norms, and Organisations

The session is devoted to the analysis of requirements on Semantic Web Technologies for the representation of norms and organisations. In the final part of the session the participants will work out the scheme of a collective document summarising such requirements, open issues, and directions for future work.

09:15-09:20 Marco Colombetti: Welcome

09:20-09:40 Leon van der Torre: Requirements on Semantic Technology for representation and reasoning on norms and normas

Thus far, the emphasis of development of technology for normative systems has been on the representation of norms in a system, such as ability to represent various kinds of norms (regulative, constitutive, permissive, procedural), sanctions, temporal elements like deadlines, powers of agents to change norms, and so on. Less attention has been paid to semantic issues like equivalence of normative systems, or redundancy of a norm. Since there are various semantics of norms, as studied for example in the input/output logic framework, I argue that the main challenge is in the latter.

09:40-10:00 Marco Colombetti: Semantic modelling of organisations

Representing the static structure and the dynamic evolution of an organisation is a complex task, with significant demands for representation and reasoning frameworks. I discuss some pros and cons of OWL representations and single out some critical aspects concerning Closed World, temporal, and deontic reasoning.

10:00-10-20 Alexandre Passant: Lightweight Semantics for enhancing Enterprise 2.0 environments

Enterprise 2.0 involves user-participation through blogs, wikis, microblogging, etc., in order to share information more easily and more broadly in corporate settings. However, it leads to various issues such as content fragmentation and the lack of machine-readable data for further processing and querying. In this talk, I will discuss how Semantic Web technologies combined with both automated and user-driven approaches for semantic annotations of social data can solve these issues, providing richer data modelling and integration in such environments, by relying on W3C standards such as RDF(S)/OWL and SPARQL

10:20-10:40 Alex Polleres and Antoine Zimmermann: Discussants
