Research interests

I hold a Ph. D. in Computer Science. Since year 2004 I’ve been working in the Natural Language Processing (NLP) area, a field of computer science and linguistics concerned with the interactions between computers and human (natural) languages. NLP has a significant overlap with computational linguistics and is considered a sub-field of artificial intelligence.

Some of the particular sub-problems of NLP in which I’m interested and I’ve done some work are:

  • Author Profiling (Sexual Predators Identification/Personality identification)
  • Plagiarism Detection (Source Code Plagiarism Identification)
  • Sentiment Analysis (Opinion mining)
  • Single and Multiple Document Summarization
  • Information Retrieval (Geographic)
  • Automatic Speaker Identification
  • Question Answering Systems
  • Information Extraction from unstructured Texts
  • Automatic Text Classification
