My research focus is “NLP in context” and mainly involves modeling and analysis of Social Network Dynamics based on various social signals ranging from language use to patterns of online activity. I use Natural Language Processing, Complex Networks Analysis and Machine Learning in the context of social interaction. I’m interested in large scale-data driven modeling of the processes in which language is shaping and shaped-by social dynamics. In particular, I’m interested in modeling social coordination, influence and contagion in social networks and in the political domain.
