My research interests are in knowledge discovery for Case-based Reasoning (CBR) Systems. I am currently interested in knowledge acquisition for Textual CBR systems. Work in this area is focused on textual feature selection and extraction applied to incident reporting tasks, email tasks and sentiment analysis. Discovery of similarity knowledge for Textual case retrieval is a further area of interest and has resulted in the development of a Propositional Semantic Indexing (PSI) scheme. I am also interested in combined approaches to similarity knowledge discovery (e.g. using Latent Semantic Indexing, association rules, Web resources including WordNet) for supervised and unsupervised textual retrieval, reuse and revision tasks.

Application domains include Health & Safety reporting, satellite anomaly detection, air crash investigation reporting, email workflow management, weather forecasting, electronic patient records, sentiment analysis from Bolgs and tag recommendation for Web applications.

Collaborators include ESA, AxSys Technology Ltd, Aberdeen University, Indian Institute of Technology Madras, Universidad Complutense de Madrid and Dundee University

Externally, I am a member of the programme committees of ECCBR, ICCBR, ECML/PKDD, FLAIRS; BCS-SGAI committe member and Expert Update editor. I am co-charing ICCBR-2011 together with Ashwin Ram from Georgia Tech.
