About

I am a Research Fellow in the Hypermedia Research Group (University of South Wales). I contribute to research activities and projects within the Hypermedia Research Group (University of South Wales) with expertise on Natural Language Processing (NLP) and Semantic Technologies, extracting highly structured knowledge from unstructured text information with specific expertise in the domain of humanities. I work for the FP7 European project Ariadne researching the multilingual application of NLP for the semantic indexing of archaeological resources. I lead the Welsh Natural Language Toolkit (WNLT) project that aims to develop a suite of open source software modules that enable Welsh Language computational linguistic application. In the past I worked as a member of the research consortium ReDrAW (Digital R&D fund for the arts in Wales) providing research support and management in the areas of digital curation and dissemination of cultural heritage and art resources.

I also teach Web Development in the Faculty of Computing, Engineering and Science. In the past I have delivered modules on Web Design, Social Media, and Search Engine Optimisation in the Cardiff School of Creative & Cultural Industries (USW) and for the DEHOV project (UHOVI).

Research

My research focuses on the use of Natural Language Processing techniques for the semantic indexing of natural language texts and in digital curation and dissemination of cultural heritage and art resources
Main Research Interests:
- Natural Language Processing techniques and applications in the context of the Semantic Web
- The role of conceptual reference models, ontologies and knowledge base resources in Information Extraction.
- Linguistic heuristics and rule based approaches aimed at Named Entity Recognition and Relation Extraction.
- Digital curation and dissemination of cultural heritage and art resources
