Dr. Derek Greene is Assistant Professor at the School of Computer Science, University College Dublin, and a Funded Investigator at the Insight Centre for Data Analytics and the VistaMilk SFI Research Centre. He received his Ph.D. from Trinity College Dublin in 2006, for work in the area of unsupervised text mining. After working as a Postdoctoral Researcher at the Machine Learning Group in UCD, he joined the SFI-funded Clique Research Cluster as a Research Fellow in May 2009 and worked in the UCD CASL institute. In July 2013, he joined the Insight Centre, where his current research focuses on scalable machine learning, network analysis, and the application of text mining in areas such as social media analytics and the digital humanities.

Current research interests:

• Text mining: Development and application of techniques for topic modeling, document clustering, text classification.
• Network analysis: Development of large-scale matrix analysis and community finding algorithms to dynamic, multi-relational graphs.
• Social media curation: Combining social network analysis, recommender systems, and text mining techniques to support the exploration and curation of content produced by users of social media platforms such as Twitter, to assist in tasks such as online journalism.
• Digital humanities: Developing algorithms and tools to support the analysis and interpretation of data from the social sciences, and corpora from literary analysis.

Recent projects:

• Nation, Genre & Gender: A comparative social network analysis of Irish and British fiction, 1800-1922.
• Analysis of European Parliament Speeches: An exploration of the political agenda of the European Parliament, 1999-2014, using dynamic topic modeling.
• Dáil Éireann Ngram Viewer: A high level visualisation of 10 years of activity in the Irish parliament.
