Applications of computer technology (knowledge representation, advanced algorithms, machine learning, software engineering), particularly to problems which involve the use of natural (human) languages and with a specific focus on lexicalist approaches.

• Natural language processing: text analytics, information extraction, text mining, sentiment and genre analysis, natural language generation, recommender systems;
• Computational lingusitics: morphology, lexicography, lexicology;
• Knowledge representation, especially as it relates to language: lexicons, ontologies, semantic web, semantic metadata, multilingual representation, distributed representations;
• Architectures and tools for language processing systems and language-based user interfaces.

Recent projects have focused on text mining and semantic metadata in Digital Humanities and Cultural Informatics, including the AHRC-funded projects TRI-PACT, DFAP and Traces Through Time, the Digging into Data project ChartEx, and the EC large-scale Integrating Project, 3D-COFORM.   Recent PhD student topics include computational lexicography, text analytics, sentiment analysis, semantic metadata, recommender systems and microservice software architectures.

Dr Roger Evans is a Reader in Computer Science in the School of Computing, Engineering and Mathematics, University of Brighton, UK, and a member of the Centre for Secure, Intelligent and Usable Systems (CSIUS).  His research explores applications of computer technology (knowledge representation, advanced algorithms, machine learning, software engineering), particularly to problems which involve the use of natural (human) languages and with a specific focus on lexicalist approaches. Recent projects have focused on text mining and semantic metadata in Digital Humanities and Cultural Informatics, including the AHRC-funded projects TRI-PACT, DFAP and Traces Through Time, the Digging into Data round 2 project ChartEx, and the EC large-scale Integrating Project, 3D-COFORM. He also supervised PhD students in topics including computational lexicography, text analytics, sentiment analysis, semantic metadata, recommender systems and microservice software architectures.

Roger graduated from Warwick (Mathematics, 1st class hons) in 1980, holds a Certificate of Advanced Study in Mathematics from Cambridge (Kings, 1981) and obtained a DPhil in Cognitive Studies (Computational Linguistics) at Sussex in 1987. He spent 9 years as a postdoctoral researcher at Sussex before moving to Brighton, where he was Deputy Head of the Information Technology Research Institute (ITRI) for 6 years, before joining the School of Computing Engineering and Mathematics. He has over 30 years of postdoctoral academic research and research management experience, supervising research staff, technical staff, PhD and masters students and successfully bidding for research and consultancy funding. He has been Principal Investigator on UKRI-funded and EC-funded grants, has led or been involved in a wide range of other research and consultancy projects, is a former SERC Advanced Fellow and a member of the EPSRC Peer Review College.  

I am interested in supervising topics in the theory and application of lexicalist linguistic representations, including inheritance-based, probabilisitic and distributed approaches, and hybrid representations.

Recent PhD student topics include computational lexicography, text analytics, sentiment analysis, semantic metadata, recommender systems and microservice software architectures.
