I work on several different projects. Mostly involving searching, browsing and editing various language corpora (PML-TQ). I am also author of the Treex::Web - a web frontend for modular NLP framework Treex.
Most projects has their repository in redmine at: https://redmine.ms.mff.cuni.cz/projects
PML Tree Query
PML-TQ is a powerful open-source search tool for all kinds of linguistaically annotated treebanks with several client interfaces and two search backends (one based on a SQL database and one based on Perl and the TrEd toolkit).
Simple web frontend build on the top of the PML Tree Query service. It's aim is to be successor of the old CGI interface.
Technically a web client for NLP framework Treex. Currently in development alpha/beta state, but is already accessible online as a part of Lindat infrastructure at: https://ufal-point.mff.cuni.cz/services/treex-web/
