Personal profile

Research interests

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 programmatic access protocols (APIs) and services for Linked Data, along with Natural Language Processing and (semi) automatic indexing for widening access to a wide range of datasets and digital reports.
