Research Interests

  • Natural Language Processing, Dialogue Systems

    • Development of complete frameworks and toolkits for rapid prototyping of dialogue systems and for supporting dialogs in serious games.
    • Data collection (i.e. Wizard-of-OZ experiments) and automatic semantic annotation of dialogue corpora.
    • Application of Machine Learning techniques for interpretation and question answer in situated dialogues.
    • Development of NLP tools for processing romance languages (e.g. Italian, French and Spanish).

  • Knowledge-representation Application of description logics knowledge-representation and inference systems to the medical domain.

  • Biomedical Text Mining and Healthcare dialogue systems. Application of Information Extraction tecniques for mining clinical reports and biomedical literature.
