(Major) News

2016/03/01 I have started my Adjunct Professor position at the University of Colorado in Boulder, Department of Computer Science, working with Martha Palmer and others on Computational Linguistics, NLP and new multilingual language resources.

2015/04/28 At the Riga Summit on the European Multilingual Digital Single Market, I was elected the chair of the META-NET Executive Board.

2015/04/20 I will take part in the new CLARIN PLUS eInfra project, just announced (Czech / CUNI PI: Pavel Stranak, UFAL).

2014/09/29 The first ICT H2020 Call results have been announced. Barring any critical problems, I will be the Charles University in Prague PI in CRACKER CSA, HimL Innovation Action and QT21 Research and Innovation Action projects, and will take part in KConnect IA project (CUNI's PI: Pavel Pecina).

Research Interests, Grants

My research interest evolved from morphology and tagging of inflective languages (lexicons, analysis and generation tools - see this demo) to machine translation (French-English while at IBM and Czech-English; also, Czech-Russian and other closely related languages). I am also interested in parsing (see e.g. the CLSP Workshop on parsing Czech) and generation. However, in the past 10 years, I devoted most of my research time to creating linguistic resources, such as the Prague Dependency Treebank family of projects (CzechEnglishArabic) and managing new research projects, mainly funded by the EU (see below for a complete list).

I am also interested in spoken language understanding. I participated in the now finishing project Malach, both on the language modeling part (for ASR), on thesaurus translation and on the IR Czech test collection.

I closely work not only with my students, but also with other Czech and foreign teams, such as the University or West Bohemia in the Czech Republic, Center for Speech and Language Processing at the JHU, Center for Spoken Language Research at CU-Boulder, Linguistic Data Consortium, and several European Universities on EU projects (see below).

I am or have been the PI, or the national PI of several major Czech, EU and NSF (US) research projects. The list of current (or of very recently finished) projects is below.

2005-2011 Center for Computational Linguistics, a virtual Center for joint research with the University of West Bohemia, Masaryk University of Brno, and the Institute of the Czech Language in Prague)
2006-2010 PIRE, a project funded by the NSF to promote U.S. graduate student education in Europe. Topic: Investigation of Meaning Representations in Language Understanding for Speech Reconstruction and Machine Translation Systems.
2002-2007 Malach, project for automatic speech recognition (in many languages) of taped interviews with Holocaust survivors, collected by the Shoah Visual History Foundation. Also, Information Retrieval experiments and resource creation.

Before that, I have been the PI or Co-PI of many other projects, such as the Czech Grant-Agency supported highly collaborative, nation-wide Czech National Corpus project (2003-2006), of several collaborative grants for mutual visits to/from U.S. institutions (Johns Hopkins University, University of Pennsylvania, Univ. of Colorado), and of several smaller subcontracting grants (such as the U.S.-based GALE project). In the 90s, I have been the Czech PI of several collaborative EU projects specifically aimed at the formerly Soviet Bloc Countries (EU project STEEL, EU project CEGLEX).

I have been working on some other grants as a researcher as well, such as the predecessor Center for Computational Linguistics (2000-2004), the Laboratory for Linguistic Data (1996-2000), Czech-English MT project supported by the Czech Grant Agency MATRACE (1993-1995), and many smaller projects.

Several industrial projects have got my attention as well, such as the Czech Grammar Checker project and certain lexicon(s) for Microsoft, morphological databases for companies like IBM, Xerox, Lotus, Morphologic, Zi Corp., Lernout & Hauspie, and cooperation on product development for several Czech companies, such as ASPI (legal information system using NL search), Oracle (the Oracle Context product) and morphological dictionary development for the Czech and Slovak portal centrum.cz and centrum.sk.
