Welcome to my homepage
I'm currently a Principal Machine Learning Engineer at Workable, a visiting researcher at Athens University of Economics and Business (AUEB), and a member of the Natural Language Processing Group of AUEB.
My research interests focus on Artificial Intelligence, especially Natural Language Processing, Information Retrieval, and Information extraction and particularly:
- information retrieval and question answering for large document collections and the world wide web,
- text classification including multi-label classification with large label-sets hierarchically organized,
- information extraction and opinion mining including sentiment analysis,
- machine learning in natural language processing, especially deep learning, transfer learning, and few/zero-shot learning, and
- natural language processing tools for Greek, for example part-of-speech taggers and pre-trained language models
