Research Interests

My general field of research is in Artificial Intelligence, especially Natural Language Processing and Semantic Web Technologies and particularly AI & Law case studies such as:

  • Deep Learning for NLP
  • Legal Text Analytics (Legislation Publishing, Contract Analysis)
  • Information Extraction (Named Entity Recognition and Linking)
  • Text Segmentation (Legal Text Segmentation, Zoning, Sentence Boundary Detection)
  • Text Classification (Document/Sentence Classification)
  • Self-supervised Document Classification
  • Low-resources Environments
  • Data Augmentation
  • Legal Knowledge Representation (Legislation, Contracts)
  • E-Government – Linked Open Data
