Current research themes

My research focuses on corpus-based statistical approaches to semantic processing and applications built thereon, including

  • distributional modeling of lexical meaning
  • lexical meaning and knowledge acquisition
  • discourse-oriented semantic analysis
  • natural language understanding
  • NLP for cultural heritage
