چکیده

In this paper we introduce the AKTive Workgroup Builder (AWB) web application and describe how it uses distributed RDF data, defined against an OWL Lite ontology, to build and solve a user defined Constraint Satisfaction Problem (CSP). We describe our approach to mixed mode reasoning using both ontological and rule based methods and discuss how some of the factors relating to this affect the design of the system. We explain how we utilise derivation rules, expressed in the Semantic Web Rule Language (SWRL) to further enrich our knowledge. Fully quantified constraints are then expressed against this semantic data using CIF/SWRL – an extension of SWRL using our Constraint Interchange Format (CIF). To the best of our knowledge, the AWB is unique in that no other semantic web application combines these various mechanisms to perform hybrid reasoning.

AKTive Workgroup Builder: Semantic Web Instance Data Reasoning

Our interest lies in exploring the interplay between ontological and rule based reasoning with instance data when applied to Constraint Satisfaction Problem (CSP) solving. The AKTive Workgroup Builder (AWB) is a Semantic Web application developed to help us achieve this aim. We share our experiences of developing the AWB – how the current technologies can influence the usability and design of s...

Implementing a Semantic Web Blackboard System using Jena

In this paper, we discuss the need for a hybrid reasoning approach to handing Semantic Web data and explain why we believe that the Blackboard Architecture is particularly suitable. We describe how we have utilised it for combining ontological inference, rules and constraint based reasoning within a Semantic Web context. After describing the metaphor on which the Blackboard Architecture is base...

Semantic Web Reasoning Using a Blackboard System

In this paper, we discuss the need for a hybrid reasoning approach to handing Semantic Web (SW) data and explain why we believe that the Blackboard Architecture is particularly suitable. We describe how we have utilised it for coordinating a combination of ontological inference, rules and constraint based reasoning within a SW context. After describing the metaphor on which the Blackboard Archi...

A Semantic Web Blackboard System

In this paper, we propose a Blackboard Architecture as a means for coordinating hybrid reasoning over the Semantic Web. We describe the components of traditional blackboard systems (Knowledge Sources, Blackboard, Controller) and then explain how we have enhanced these by incorporating some of the principles of the Semantic Web to produce our Semantic Web Blackboard. Much of the framework is alr...

Supporting Collaboration Through Semantic-Based Workflow and Constraint Solving

This paper describes our efforts to provide a collaborative problem solving architecture driven by semantic-based workflow orchestration and constraint problem solving. These technologies are based on a shared ontology that allows two open systems of very different natures to communicate, perform specialised tasks and achieve common goals. We give an account of our approach and the semantic bas...
