The research group, founded in 1996, is headed by Prof. Alexander Gelbukh and includes faculty members Prof. Grigori Sidorov and Prof. Ildar Batyrshin, external collaborators Hiram Calvo, Olga Kolesnikova, Sofía Galicia Haro, Igor Bolshakov, Soujanya Poria, and a number of PhD and MSc students from various countries. Our students have received important awards. Here is an older version of this page.

The group conducts research in natural language processing and related disciplines and application fields of artificial intelligence and soft computing. Current research interests of the members of the group include:

We organize the annual series of international conferences CICLing, participate in the organization of the international conferences MICAI and of 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.
