Research interests

My research interests include Natural Language Processing, Knowledge Processing and Artificial Intelligence. I am particularly interested in the inteaction between semantics and pragmatics in the following contexts:

  • Information extraction with a focus on relation extraction from texts and knowledge graphs validation
  • Discourse processing: rhetorical relations identification, semantics of rhetorical relations
  • Evaluative language processing:
    • Opinion and sentiment analysis: lexical semantics and subjectivity lexicons, negation and hedging, discourse-based sentiment analysis, opinion and judgment aggregation
    • Figurative language processing: irony and sarcasm
    • Hate speech and stereotypes detection
    • Intention detection : NLP approaches to crisis management, preference extraction from dialogues
  • Arabic natural language processing (including dialects)

Teaching activities

My teaching mainly focuses on Artificial intelligence and Algorithmic and programming languages. Other themes include: Databases, Introduction to networks, computer architectures, and computer systems.
