I am a Professor in the School of Computer Science & Informatics at Cardiff University. I am a member of the Data & Knowledge Engineering group and the leader of the Text & Data Mining theme.
The main focus of my academic career has been to establish excellence in research related to text mining, which is the key to gaining knowledge for significant interventions and decision making in the context of big data. This makes it indispensible to other disciplines and has led to deep interdisciplinary collaboration which has been highly successful, leading to impact beyond computer science and informatics as well as developments in my home discipline. In particular, I have made contributions in areas of text classification, information extraction, term recognition and sentiment analysis (see infographics).
