The Linguistic Data Consortium (LDC) is pleased to announce the
availability of the Prague Dependency Treebank 1.0.
http://www.ldc.upenn.edu/Catalog/LDC2001T10.html
This single CD-ROM Czech language release contains the following
material:
* Morphologically and syntactically annotated Czech data, 1.8MW
* Czech-English parallel Corpus, aligned, 0.9MW/1MW
* Czech raw texts (newspaper and journals), over 30MW
* Czech NLP tools (morphology, tagging)
* General annotation tools (tree editors, tree viewer)
The Prague Dependency Treebank (PDT) is currently being developed
by Jan Hajic, Eva Hajicova, Petr Pajas, Jarmila Panevova, Petr Sgall,
Barbora Vidova Hladka at Charles University, Prague in the Czech
Republic. This long-term project consists of two major phases. During
the first phase (1996-2000), the morphological and syntactic analytic
layers of annotation were completed. This annotation, together with a
preview of tectogrammatical layer annotation, is available as PDT 1.0.
PDT 0.5 ('half through') was released online by Charles University in
1998 and it contains 456,705 tokens (words and punctuation) in 26,610
sentences. This release has been downloaded by 90 researchers and/or
sites from 19 countries. The current release, PDT 1.0, contains about
three times more tokens and sentences than PDT 0.5.
During the second phase (2000 - 2004), the tectogrammatical layer
of annotation will be conducted; at the conclusion of this phase,
PDT 2.0 will be available.
Institutions that have membership in the LDC during the 2001

Nonmembers may purchase this publication for $100. Please note
that an online user agreement form must be completed for both member
requests and nonmember purchases.
