About Me

Currently, from April 2013, I am a Software Engineer/Researcher at Institute for Language and Speech Processing where I have been involved in various research projects such as:

  • OpenMinTeD: Open Mining INfrastructure for TExt and Data.
  • CLARIN-EL: Common Language Resources and Technology Infrastructure.
  • QTLaunchpad: A European Commission-funded project aiming to improve translation technology.

Previously, from March 2012 to December 2012, I did my (compulsory) military service in Greek Army.

From June 2006 to February 2012, I worked as a Software Engineer/Researcher at the Natural Language Processing Group of the Department of Informatics in Athens University of Economics and Business (AUEB); the projects in which I was involved are listed below.

  • "A linear programming approach to multi-document text summarization and natural language generation from ontologies". AUEB Basic Research Funding Program (BRFP) project (04/2011-08/2012).
  • Indigo: Interaction with mobile robots that have personalities and support multimodal dialogues. European FP6-IST project (02/2007-01/2010).
  • Xenios: Human-robot interaction using speech processing, natural language generation, and computer vision. National "Information Society" project (06/2006-12/2007).
Also, in parallel, from Nov. 2006 to Feb. 2012 I was doing my Ph.D. in the same department.

I hold

My research interests include Natural Language Generation, Semantic Web, Question Answering, Sentence Compression, Query-Focused Summarization and Sentiment Analysis.
