Vasiliki Kougia

About me:

I am a Ph.D. student in Computer Science at the University of Vienna, supervised by Prof. Benjamin Roth. My research interests are machine learning (ML) and Natural Language Processing (NLP). I currently work on weak supervision methods for NLP tasks, especcially sequence labeling. I am also interested in multimodal methods combining text and images.

Previously, I was a research assistant in the EXTREMUM Project and member of the Data Science Group at Stockholm University, Sweden. I received my M.Sc. degree in Computer Science from Athens University of Economics and Business in 2019. I am a research assistant and member of the Natural Language Processing Group at Athens University of Economics and Business, Greece.
