A small subset of PDT 2.0 made available under a permissive license.
Prague Dependency Treebank 2.0 (PDT 2.0) contains a large amount of Czech texts with complex and interlinked morphological (2 million words), syntactic (1.5 MW) and complex semantic annotation (0.8 MW); in addition, certain properties of sentence information structure and coreference relations are annotated at the semantic level.
PDT 2.0 is based on the long-standing Praguian linguistic tradition, adapted for the current Computational Linguistics research needs. The corpus itself uses the latest annotation technology. Software tools for corpus search, annotation and language analysis are included. Extensive documentation (in English) is provided as well. and * Ministry of Education of the Czech Republic projects No. VS96151, LN00A063, 1P05ME752, MSM0021620838 and LC536,

The Prague Dependency Treebank 2.5 annotates the same texts as the PDT 2.0. The annotation on the original four layers was fixed or improved in various aspects (see Documentation). Moreover, new information was added to the data:

PDT 3.0 is a new version of Prague Dependency Treebank. It contains a large amount of Czech texts with complex and interlinked morphological (2 million words), syntactic (1.5 MW) and semantic annotation (0.8 MW); in addition, certain properties of sentence information structure, multiword expressions, coreference, bridging relations and discourse relations are annotated at the semantic level. and the Grant Agency of the Czech Republic: grants P406/12/0658 "Coreference, discourse relations and information structure in a contrastive perspective", P406/2010/0875 "Computational Linguistics: Explicit description of language and annotated data focused on Czech", 405/09/0729 "From the structure of a sentence to textual relationships", and GPP406/12/P175 (Selected derivational relations for automatic processing of Czech);

The Prague Dependency Treebank 3.5 is the 2018 edition of the core Prague Dependency Treebank (PDT). It contains all PDT annotation made at the Institute of Formal and Applied Linguistics under various projects between 1996 and 2018 on the original texts, i.e., all annotation from PDT 1.0, PDT 2.0, PDT 2.5, PDT 3.0, PDiT 1.0 and PDiT 2.0, plus corrections, new structure of basic documentation and new list of authors covering all previous editions. The Prague Dependency Treebank 3.5 (PDT 3.5) contains the same texts as the previous versions since 2.0; there are 49,431 annotated sentences (832,823 words) on all layers, from tectogrammatical annotation to syntax to morphology. There are additional annotated sentences for syntax and morphology; the totals for the lower layers of annotation are: 87,913 sentences with 1,502,976 words at the analytical layer (surface dependency syntax) and 115,844 sentences with 1,956,693 words at the morphological layer of annotation (these totals include the annotation with the higher layers annotated as well). Closely linked to the tectogrammatical layer is the annotation of sentence information structure, multiword expressions, coreference, bridging relations and discourse relations.
The Prague Dependency Treebank of Spoken Czech 2.0 (PDTSC 2.0) is a corpus of spoken language, consisting of 742,316 tokens and 73,835 sentences, representing 7,324 minutes (over 120 hours) of spontaneous dialogs. The dialogs have been recorded, transcribed and edited in several interlinked layers: audio recordings, automatic and manual transcripts and manually reconstructed text. These layers were part of the first version of the corpus (PDTSC 1.0). Version 2.0 is extended by an automatic dependency parser at the analytical and by the manual annotation of “deep” syntax at the tectogrammatical layer, which contains semantic roles and relations as well as annotation of coreference.
Annotation of discourse relations is a project related to the Prague Dependency Treebank 2.5. It represents a new manually annotated layer of language description, above the existing layers of the PDT, and it portrays linguistic phenomena from the perspective of discourse structure and coherence. and GACR P406/12/0658, GACR P406/2010/0875, GACR 405/09/0729, Ministry of Education ME10018, Ministry of Education LM2010013
PDiT 2.0 is a new version of the Prague Discourse Treebank. It contains a complex annotation of discourse phenomena enriched by the annotation of secondary connectives.
The Prague Discourse Treebank 3.0 (PDiT 3.0) is a new version of annotation of discourse relations marked by primary and secondary discourse connectives in the data of the Prague Dependency Treebank. With respect to the previous versions, PDiT 3.0 brings a largely revised annotation of discourse relations and offers the data also in the Penn Discourse Treebank 3.0 (PDTB 3.0) format and sense taxonomy.
Preamble 1.0 is a multilingual annotated corpus of the preamble of the EU REGULATION 2020/2092 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL. The corpus consists of four language versions of the preamble (Czech, English, French, Polish), each of them annotated with sentence subjects.
The data were annotated in the Brat tool (https://brat.nlplab.org/) and are distributed in the Brat native format, i.e. each annotated preamble is represented by the original plain text and a stand-off annotation file.
The dataset used for the Ptakopět experiment on outbound machine translation. It consists of screenshots of web forms with user queries entered. The queries are available also in a text form. The dataset comprises two language versions: English and Czech. Whereas the English version has been fully post-processed (screenshots cropped, queries within the screenshots highlighted, dataset split based on its quality etc.), the Czech version is raw as it was collected by the annotators.
