QLVL members - Thomas Wielfaert


Thomas holds a Master's of English literature and linguistics from Ghent University (2009) and a Master's of Advanced Studies in Linguistics: interdisciplinary linguitics (major: computational linguistics) from the University of Antwerp (2010). He is pursuing a PhD on distributional semantics (so-called Word Sense Induction) for lexical semantic purposes under the supervision of prof. dr. Dirk Speelman and prof. dr. Dirk Geeraerts.

Thomas's research is part of the 3H120217 OT-project "From lexical to semantic sociolectometry: New methods for the corpus-based analysis of variation in lexical categorization." funded by the KU Leuven Research Fund (BOF). Token-level Semantic Vector Space models (an extension of Hinrich Schütze's 1998 paper) are used to model semasiological variation, i.e. polysemy, in an automatic and unsupervised way.

Other research interests include:

  • (Linguistic) data visualisation
  • Language variation and change, with a focus on Dutch
  • Topic modelling (LDA) for semantic purposes
  • Applications of distributional semantics for language technology
  • Cluster analysis techniques
