Tutorial
#1: Semantic Web Policies: Where Are We and What Is Still Missing?
PRESENTERS
- Piero A. Bonatti, University of
Naples, Italy
- Daniel Olmedilla, L3S Research
Center & Hanover University, Germany
ABSTRACT
The term policy is often overloaded.
A general definition might be "a statement that defines the behaviour
of a system". However, such a general definition encompasses different
notions, including security policies, trust management policies,
business rules and quality of service specifications, just to name a
few. Researchers have mainly focussed on one or more of such notions
separately but not on a comprehensive view. Policies are pervasive in
web applications and play crucial roles in enhancing security, privacy,
and service usability as well. Interoperability and self-describing
semantics become key requirements and here is where Semantic Web comes
into play. There has been extensive research on policies, also in the
Semantic Web community, but there still exist some issues that prevent
policy frameworks from being widely adopted by users and real world
applications.
This tutorial aims at providing an
overall view of the state of the art (requirements for a policy
framework, existing policy frameworks/languages, policy negotiation,
context awareness, etc.) as well as open research issues in the area
(policy understanding in a broad sense, integration of trust
management, increase in system cooperation, userawareness, etc.)
required to develop a successful Semantic Policy Framework.

Tutorial
#2: Bridging Research and Practice - Making Real-World Application of
Ontologies and Rules
PRESENTERS
- Harold Boley, NRC, Canada
- Holger Knublauch, Top Quadrant,
USA
- Adrian Paschke, TU Munich, Germany
ABSTRACT
A number of key business needs and
challenges motivate solutions based on semantic technology and rules.
The tutorial starts with exploring these motivations by setting
specific business contexts, drivers, forces and challenges typically
met in information systems across most of industry. Following this, is
an overview and positioning of industry standards for ontologies (RDFS,
OWL, SPARQL and SWRL) and rules (SBVR, PRR, RIF, RuleML,
Jess). Ontology-rule integration (SWRL, RDF Gateway) and reactive
rules (viaReaction RuleML) will also be covered.The tutorial will describe and
demonstrate development environments (Protege, SWOOP and TopBraid
Composer <http://www.topbraidcomposer.com)
and execution engines (KAON2, Pellet, Racer). Using use cases and
qualifying criteria developed at W3C, some specific solution archetypes
will be described using Capability Cases ( http://www.capabilitycases.org
).
One use case and its solution
architecture will be developed in full. The tutorial will evaluate the
real-world applicability of the solutions discussed.
