For using PDT 2.0, you have to fill in the License form and sign it electronically (for an exception, see below). See the text of the License in Section 7.1, "License agreement".
There are two ways to get PDT 2.0. The standard way is to order the full PDT 2.0 distribution through the Linguistic Data Consortium at http://www.ldc.upenn.edu; during the ordering process, you will be redirected to the form-based License web page, which you have to fill in for your order to be completed.
The other option is to browse parts of PDT 2.0 directly on our web pages at http://ufal.mff.cuni.cz/pdt2.0; it is an exact copy of the distribution provided by LDC, but only a small sample of the annotated data is included. You can do so before or after filling the registration form based on the License at http://ufal.mff.cuni.cz/corp-lic/pdt20-reg.html, but you are not allowed to use anything what you have downloaded (tools, sample data, etc.) without filling in the form. In other words, this license is not valid until registration.
Parts of the distribution might be covered by the GNU Public License (GPL). Such tools and data packages explicitly say so (they are typically available also from other sources, such as author's personal web pages and standard Open Source and GNU software repositories, e.g. from sourceforge.net). In such a case, the GPL has precedence over this license. If the material you have downloaded or are using consists solely of such GPL-covered tools and data packages, you are not required to register under this license; however, we would like you to do so anyway (even though in fact its rules and conditions do not materially affect you in such a case) to help us secure future funding by having as many registered users as possible.

The Prague Dependency Treebank version 2.0 (PDT 2.0) is a collection of textual data and documentation containing linguistic annotations and software tools for their processing as described in the documentation, developed at and by the Proprietor under the following support: Ministry of Education of the Czech Republic projects No. VS96151, LN00A063, 1P05ME752, MSM0021620838, and LC536, Grant Agency of the Czech Republic grants Nos. 405/96/0198, 405/96/K214 and 405/03/0913, research funds of the Faculty of Mathematics and Physics, Charles University, Czech Republic, Grant Agency of the Academy of Sciences of the Czech Republic No. 1ET101120503 and 1ET101120413, Grant Agency of the Charles University No. 489/04, 350/05, 352/05 and 375/05 and the U.S. NSF Grant #IIS9732388.
The Proprietor is the copyright holder of PDT 2.0 and is entitled to grant a license to the User.
The User is an academic, educational or research institution, or other organization, or an individual wishing to make use of PDT 2.0 for research and/or education purposes.
It is hereby agreed as follows:
This agreement is made on the date of submission and effective immediately.
The User is granted a non-exclusive license to use, modify, enlarge or enrich PDT 2.0 to extract information directly or indirectly in any form and volume, provided that PDT 2.0 itself or any derivative work is used only by the User her/himself or his/her immediate collaborators, employees, managers and/or her/his students from the same Institution for research purposes only, and provided she/he is continuously observing all the terms and conditions contained in this Agreement. If any part of PDT 2.0 contains its own license or an additional restriction, the more restrictive version and/or amendment of the license shall be in effect, unless specifically stated otherwise in such a part. In particular, all the documentation which is provided in either RTF, PDF or PostScript format should be considered a personal copy of the respective Author's reprint and handled as such.
The User shall not use PDT 2.0 itself or any derivative work (including but not limited to statistics obtained by using it or any derivative work thereof) based on it (however small the contribution of PDT 2.0 to such derivative work is) in whatever form for commercial purposes of any kind, nor for a deployment in any routinely used application, regardless whether it is of commercial nature or not.
The User shall include the following notice in all publications or publicly available materials, regardless of their form (printed, electronic, or other), describing work which uses PDT 2.0: "The Prague Dependency Treebank, version 2.0 has been developed by the Institute of Formal and Applied Linguistics, http://ufal.mff.cuni.cz/." In the case of printed materials, such as papers, journal articles, etc., one publication most suitable for reference with regard to User's work should be included from the list in the PDT 2.0 documentation; in the case of electronic publications on the Internet, the reference to the aforementioned web page should be included as a web link. Due to Proprietor's obligations with regard to the text copyright holders, text examples and citations from PDT 2.0 or any derivative work (regardless whether they include any annotations or not) are limited to 200 words per publication or series of publications on the same topic (whether printed, electronic, or in any other form).
The User agrees not to re-distribute or otherwise make publicly available PDT 2.0, or any derivative work based on it as described in paragraph 3, to a third party without a prior written permission of the Proprietor, with the exception of examples and citations as described in paragraph 4.
The User undertakes to adopt any security measures needed to protect the Proprietors' copyright in PDT 2.0 and undertakes to take all reasonable steps to ensure that no unauthorized use is made of PDT 2.0 and of any copies, derivative works or extracts thereof.
Any usage of PDT 2.0 which does not conform to the specification set forth in the 3rd paragraph of this Agreement (such as, e.g., commercial usage of PDT 2.0) is subject of separate negotiations and a written contract between the User and the Proprietor and/or other parties. The Proprietor is in general not obliged to enter and/or conclude such negotiations.
PDT 2.0 is provided as is. Therefore the Proprietor does not warrant the usefulness of PDT 2.0 for any purpose, regardless of formulations which can be found at some places in the accompanying documentation stating the intended purpose and use of PDT 2.0.
If the User reports to the Proprietor any discovered errors, inconsistencies or suggested corrections or improvements to PDT 2.0, the Proprietor undertake: (a) to maintain these comments in confidence and to use them only for the purposes of improving, modifying and/or maintaining PDT 2.0, (b) not to disclose the comments except in confidence to those of their employees or directors who need to know the same for the aforesaid purpose.
Should the Users by themselves or anyone acting on their behalf fail to comply with any of the conditions in this agreement (save with the written consent of the Proprietor) this agreement shall terminate immediately and PDT 2.0, its copies and derivative works based on it shall be destroyed at the User's site and at all sites under his control. Such termination shall be without prejudice to any claim which the Proprietor may have either for monies due and/or damages and/or otherwise.
Failure by the Proprietor to exercise or enforce any rights in this agreement shall not be deemed to be a waiver of any such right nor operate so as to bar the exercise or enforcement thereof at any time or times thereafter.
This agreement terminates if (a) the User destroys all copies of PDT 2.0 or any derivative work thereof, (b) the User or its Institution ceases to exist, unless all its obligations are transferred to a new entity, which is then considered to be bound by this Agreement. The User or its successor shall inform the Proprietor about any such transfer or succession; failure to do so will terminate this Agreement after one month after such transfer or succession. (c) the Proprietor ceases to exist without a legal successor.
The Proprietor shall keep the information about the User provided when submitting this Agreement in confidentiality and will not disclose it to other parties, except in a summary form such that individual users will not be identified, unless they specifically agree to such a disclosure in writing.
This agreement is governed by the laws of the Czech Republic and all disputes concerning this agreement will be resolved by its jurisdiction.
