I have a BSc in Computer Science from the University of Edinburgh. I completed my PhD in 1981 from the University of Wales (Swansea) on knowledge-based recognition of logic schematic diagrams. Before joining the University of Glamorgan in 1989, I worked as a programmer/analyst at the University of California, San Diego for the Faint Object Spectrograph project, one of the original instruments on the Hubble Space Telescope.


My main research interests are in Knowledge Organization Systems (KOS) and Services. I am interested in how semantically indexed hypermedia systems can assist interactive and automatic retrieval. KOS (eg classifications, gazetteers, ontologies, taxonomies and thesauri) provide controlled vocabularies which model semantic structure for the purpose of facilitating information retrieval. A vast legacy of different types of KOS for different domains is available. Formally expressed they can offer a cost-effective lightweight semantics for a wide range of online services. In current research, we are exploring the potential of standard representation formats, such as SKOS and standard programmatic access protocols for interoperable services.

Recent publications and presentations are listed in the Hypermedia Research Unit’s Publications and information on particular projects can be found under the KOS research area. See USW Research Repository for Open Access full text versions

I was Work Package Leader on the FP7 ARIADNE project. I was PI on the EPSRC funded FACET project and the AHRC funded STAR, STELLAR and SENESCHAL projects.

I have collaborated on various JISC funded projects in the general areas of social tagging and terminology registries. I am the first author of a state of the art Review on Terminology Services and Technology commissioned by the JISC.

Other research interests include Geographical Hypermedia and ontology-based approaches to spatial information, when limited GIS co-ordinate data is available, as well as research on the social context of computer system development and Participatory Design techniques. I am particularly interested in the application of qualitative and interactionist social science perspectives to design and evaluation. Several publications resulted from an ESRC funded project on the use of prototyping and Rapid Application Design in commercial information systems development.

If you are interested in the possibility of PhD research you are welcome to contact me or look at current activities in the Hypermedia Research Unit.


I am an Editor of the journal The New Review of Hypermedia and Multimedia (NRHM) – now included in Science Citation Index Expanded™. Published by Taylor & Francis, the journal covers hypermedia, hypertext, interactive multimedia, related digital library and web technologies and user studies. NRHM’s homepage has instructions for authors and the latest call for papers. Since 2003 NRHM appears both print and online. Authors are welcome to email with any questions.

I co-edited (with Marianne Lykke Nielsen) a special NRHM issue in 2006 on Knowledge Organization Systems and Services The Introduction is freely available.

I co-edited (with Traugott Koch) a special issue, JoDI 4(4), on New applications of Knowledge Organisation Systems in 2004.

I am a member of the NKOS network on Networked Knowledge Organisation Systems/Services and have co-organised 18 NKOS workshops or special sessions at various conferences. For details, see NKOS Workshops
