Past projects: PhD thesis (2013)

  • Semantic relatedness
  • Using large text collections to

learn statistical models of distributional semantics

  • … with applications to short

text categorization and search.

  • … EU project iCOP for

categorization of texts.

Past projects: NLP for Social Network Analysis (2014)

  • Based on a start-up company

specializing on SNA

  • Mining Facebook and

VKontakte social networks.

  • Analysis of posts, groups,

comments, …

  • … with respect to sentiment,

topic, gender, age, etc.

  • … mostly for doing user

segmentation and targeting.
