I am Anca Dumitrache , a Data Scientist in the Strategy & Analytics team at Albert Heijn .
I did my PhD in the User-Centric Data Science group at Vrije Universiteit Amsterdam , where I was part of the CrowdTruth project. I studied how to capture and interpret inter-annotator disagreement in crowdsourcing , and how to use this disagreement to get better training data for natural language processing models.
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).
