Professor Aravind Joshi, dr.h.c. of Charles University, has died

Professor Aravind Joshi, Henry Salvatori Professor Emeritus of Computer and Cognitive Science Computer and Information Science at University of Pennsylvania, PA, USA and a honorary doctor of Charles University has passed away on December 31st, 2017. As an outstanding scientist in the field of computational linguistics and cognitive science, he was the author of the formalism of tree-adjoining grammar, a formalism the primitive notions of which are trees rather than strings and which stands in-between the context-free and context sensitive types of grammars. More recently, he devoted lot of interest in the analysis of discourse and its application for the development and annotation of computational text corpora. Professor Joshi was deeply interested in the research carried out at the Institute of Formal and Applied Linguistics at the Faculty of Mathematics and Physics at Charles University, frequently visited Prague, delivered lectures there and was our partner in joint research projects. His friendly advice, substantial contribution to our research and, last but not least, his charming smile will never be forgotten.

Valency Lexicon of Czech verbs


The book is a collection of linguistically annotated data and documentation, resulting from a formal description of valency frames of Czech verbs.

The data, more than 10 800 lexical units, is extended by a grammar capturing systemic changes in valency structure.

Introducing Jana Straková Kravalová

My research interests involve named entity recognition, tagging and artificial neural networks.

My doctoral thesis Neural Network Based Named Entity Recognition presents recent advances in Czech NER.

I am one of the authors of NameTag, an open-source software for NER.
