The research group, founded in 1996, is headed by Alexander Gelbukh and includes faculty members Grigori Sidorov and Ildar Batyrshin, external collaborators Hiram Calvo, Olga Kolesnikova, Sofía Galicia Haro, Igor Bolshakov, Soujanya Poria, and about 50 PhD and MSc students from various countries. See a video presentation (mostly in Spanish).

Our students receive very attractive  scholarships and win important  awards.

The group conducts research in natural language processing (NLP) and related fields of artificial intelligence and soft computing. Our current work includes:

• Natural language processing

  • Computational linguistics

  • Human language technologies

  • Machine translation

  • Text similarity measures

  • Applications of syntactic n-grams and other linguistically-motivated features

  • Word sense disambiguation

  • Text summarization

  • Learning and applications of collocations

  • Automatic analysis of machine-readable dictionaries

  • Morphological analysis and generation

  • Analysis of Wikipedia and other semi-structured lexical resources

  • Syntactic disambiguation, grammars, and parsing

  • Anaphora resolution

• Social network analysis

• Twitter analysis

•  

  Social and human-oriented computing

  • Sentiment analysis

  • Emotion detection

  • Personality recognition from text

  • Social network analysis

  • Analysis of texts in Twitter and Facebook

  • Authorship attribution based on linguistic information

  • Plagiarism detection

  • Applications in law and security and analysis of legal texts

• Soft computing and applications

  • Artificial Intelligence

  •  Machine Learning

  • Theory of association measures

e the annual series of international conferences CICLing, participate in the organization of the international conferences MICAI, COMIA, and a number of other conferences and journals (see e.g. here). We wrote a book on Computational Linguistics (in English) and another book on Natural Language Processing (in Spanish). Many of our publications (below) can be downloaded from this page and from the personal pages of the members of the group. Here is an older version of this page.
