OWL and OWL-S for Dependability-Explicit Service-Centric Computing
Found in: Service-Oriented Computing: Consequences for Engineering Requirements
By Glen Dobson
Issue Date:September 2006
pp. 4
In this position paper an attempt is made to relate dependability-explicit computing to the semantic web. The machine understandable nature of the semantic web suggests a way to reconcile the increasingly autonomous nature of service-based systems with the...
 
Disambiguating Availability Specification through the use of OWL
Found in: Service-Oriented Computing: Consequences for Engineering Requirements
By Glen Dobson, Ian Sommerville
Issue Date:September 2006
pp. 5
Many Quality of Service (QoS) languages exist. However, not only do few encompass dependability, none acknowledge the semantic complexity of the vocabulary they provide. This paper presents a Quality of Service ontology which provides not only an extensibl...
 
Migrating to SOAs by Way of Hybrid Systems
Found in: IT Professional
By John Hutchinson, Gerald Kotonya, James Walkerdine, Peter Sawyer, Glen Dobson, Victor Onditi
Issue Date:January 2008
pp. 34-42
A progressive-evolution strategy for migrating systems to service-oriented architectures should minimize the risk to investments in existing software systems while letting businesses exploit the benefits of services.
 
A Domain-Independent Ontology for Non-Functional Requirements
Found in: E-Business Engineering, IEEE International Conference on
By Glen Dobson, Stephen Hall, Gerald Kotonya
Issue Date:October 2007
pp. 563-566
Despite considerable research on ontologies for representing requirements models (and metamodels), little progress has been made in using ontologies to represent non-functional requirements. Non-functional requirements define the overall qualities of the r...
 
Evolving Existing Systems to Service-Oriented Architectures: Perspective and Challenges

A Faceted Approach to Service Specification
Found in: Internet and Web Applications and Services, International Conference on
By James Walkerdine, John Hutchinson, Pete Sawyer, Glen Dobson, Victor Onditi
Issue Date:May 2007
pp. 20
Service-centric computing is developing and maturing rapidly as a paradigm for developing distributed systems. In recent years there has been a rapid growth in the number and types of processes being proposed to support aspects of SOC. Many of these proces...
 
Towards Unified QoS/SLA Ontologies
Found in: IEEE Services Computing Workshops
By Glen Dobson, Alfonso Sánchez-Macián
Issue Date:September 2006
pp. 169-174
This paper reports on work in progress to produce a unified Quality of Service (QoS) ontology This ontology must be applicable to the main scenarios currently identified such as QoS-based Web Services selection, QoS monitoring and QoS adaptation. An evalua...
 
Using WS-BPEL to Implement Software Fault Tolerance for Web Services
Found in: EUROMICRO Conference
By Glen Dobson
Issue Date:September 2006
pp. 126-133
One area of the web services architecture yet to be standardised is that of fault tolerance for services. At the same time, WS-BPEL is moving from a de facto standard to an OASIS ratified standard for combining services into processes. This paper investiga...
 
QoSOnt: a QoS Ontology for Service-Centric Systems
Found in: EUROMICRO Conference
By Glen Dobson, Russell Lock, Ian Sommerville
Issue Date:September 2005
pp. 80-87
<p>This paper reports on the development of QoSOnt: an ontology for Quality of Service (QoS). Particular focus is given to its application in the field of servicecentric systems. QoSOnt is being developed to promote consensus on QoS concepts, by prov...
 
Ontology-aided Translation in the Comparison of Candidate Service Quality
Found in: Service-Oriented Computing: Consequences for Engineering Requirements
By Konstantinos Zachos, Glen Dobson, Pete Sawyer
Issue Date:September 2008
pp. 30-37
In engineering service-centric systems, it is possible to receive early feedback on candidate services that best match requirements. This includes the possibility of comparing the quality (not just functionality) of candidate services. This paper concentra...
 
Specifying and Constructing a Fault-Tolerant Composite Service
Found in: Web Services, European Conference on
By V.O. Onditi, Glen Dobson, John Hutchinson, James Walkerdine, Pete Sawyer
Issue Date:November 2008
pp. 135-142
This paper proposes a means to specify the semantics of fault tolerant web services at an abstract level using semantics adapted from queuing system theory. A framework that supports the implementation of specified fault-tolerance is also described. Based ...
