Discovering the structure of natural language sentences by unsupervised and semi-supervised methods

(Odhalování struktury vět přirozeného jazyka pomocí neřízených a částečně řízených metod)

This is my topic for PhD studies (and my dissertation). I am only starting my work on the topic. However, my work on HamleDT is also part of my studies, as it is related to the topic.

Fairytale Child Chatbot / Chatbot Pohádkové dítě

EN: A simple console chatbot that wants to hear a fairly tale from you!
CS: Jednoduchý konzolový chatbot, který od vás chce vyprávět pohádku!
Visit/navštivte Pohádkové dítě / Fairytale Child


I am a member of HamleDT, which is a project of harmonizing dependency treebanks for various languages.


Depfix is a system for automatic post-editing of machine translation outputs. It was developed as a part of the Faust project and its development continues as a part of the QTLeap project.


Currently, my main project is QTLeap, a project aimed at significantly improving the quality of machine translation using deep language processing approaches.


I am also currently employed on the Khresmoi project, focusing of machine translation of medical texts for information retrieval (translation of search queries and resulting snippets).


MSTperl is a reimplementation of the Maximum spanning tree dependency parser (McDonald et al., 2005) in Perl. It is tuned for Czech and has several advanced features that are useful for parsing the machine-translated sentences by Depfix.

Curriculum Vitae

You can download my CV either in English or in Czech.


I help Zdeněk Žabokrtský with teaching the NLP Technology course.
