Personal profile

Personal information

I am Anca Dumitrache, a PhD student in the User-Centric Data Science group at Vrije Universiteit Amsterdam.

For the past 4 years I’ve been involved in the CrowdTruth project, where we look into how to capture and interpret inter-annotator disagreement in crowdsourcing. I am investigating how to use this disagreement to get better training data for natural language processing models. My supervisors are Lora Aroyo and Chris Welty.

Other interests I have include machine learning, Semantic Web, open data and data science in general. My programming languages of choice are R and Python (particularly the scientific Python stack).

In the past, I’ve done internships in the Watson group at IBM Research, and in the NLP department at Google Research, both in New York. I’ve also been a recipient of the IBM PhD Fellowship from 2014 to 2016.
