This is my personal project on cross-lingual syntax modelling. It is a realization of my PhD topic (the full official topic is "Odhalování struktury vět přirozeného jazyka pomocí neřízených a částečně řízených metod", the so far unofficial English translation is "Discovering the structure of natural language sentences by unsupervised and semi-supervised methods"), and it is realized under my GAUK grant, Modelling dependency syntax across languages.


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


My second-main project is HimL, focusing on semantically sane translation of medical texts from English to Czech, German, Romanian and Polish (also see Depfix).

HamleDT & Universal Dependencies

I am a member of the HamleDT group, which is a project of harmonizing dependency treebanks for various languages. (This is closely related to my dissertation.) I am also a member of the Universal Dependencies project.


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 HimL project.


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. Recently, I have started using it for delexicalized parser transfer, so it now also has some advanced features for that.
