Overview
This project focuses on the development of semantic technologies aimed at enhancing trust, dependability and re-use in the context of both consumer and enterprise applications. A central theme is the development of semantic web technologies for service-oriented architectures and pervasive computing environments. This includes developing infrastructures for enforcing a variety of policies, from security and privacy policies to corporate and even regulatory policies. Rather than assuming that ontologies and annotations are available from the start, we are also attempting to address the chicken-and-egg problem often associated with the deployment of semantic web technologies. In particular, our work on service-oriented architectures includes mixed initiative frameworks for service composition, focusing on the development of user-oriented services that work from day one even in the presence of incomplete and possibly inconsistent ontologies and annotations.

Current Applications
-
MyCampus: A mobile and pervasive computing environment based on a semantic web service architecture to support the rapid prototyping of context aware applications. Contextual attributes are modeled as web services with rich semantic profiles that can be discovered and access subject to rich privacy and security policies.
-
Enforcing Rich Context-sensitive Policies:
A service oriented architecture for enforcing complex policies, including security policies as well as other corporate and regulatory policies. The architecture relies on customizable Policy Enforcing Agents (PEA) that are capable of dynamically identifying relevant sources of information (modeled as web services with semantic annotations) to enforce rich, context-sensitive policies.
- Mixed Initiative Environment for Semantic Web Service Composition: This technology has been demonstrated in the context of SAP's Guided Procedures framework, a key element of SAP's Enterprise Service Architecture (ESA)
