Prague Discourse Treebank 4.0

Prague Discourse Treebank 4.0 (PDiT 4.0)

The Prague Discourse Treebank 4.0 (PDiT 4.0; Synková et al. 2024) is an annotation of discourse relations marked by primary and secondary discourse connectives in the whole data of the Prague Dependency Treebank - Consolidated 1.0 (PDT-C 1.0). With respect to the previous versions (see a complete list below), annotating discourse relations in the whole PDT-C 1.0 means a significant increase in the size of the annotated data.

PDiT 4.0 annotates the whole PDT-C 1.0, i.e. all of its four subcorpora:

• Prague Dependency Treebank (PDT); in the previous versions, PDiT only covered these data
• Prague Czech-English Dependency Treebank (PCEDT); newly annotated in PDiT 4.0
• Prague Discourse Treebank of Spoken Czech (PDTSC); newly annotated in PDiT 4.0
• Faust; newly annotated in PDiT 4.0

Already since version 3.0, PDiT uses two taxonomies of types of discourse relations:

• the original Prague taxonomy of discourse types, and
• the Penn Discourse Treebank 3.0 (PDTB 3.0; Prasad et al. 2019) taxonomy of discourse senses.

Also since version 3.0, the PDiT data are offered in two formats:

• the native format of the PDT-C 1.0, i.e. the Prague Markup Language, where the discourse relations are annotated on top of deep-syntax dependency trees (tectogrammatics), and
• the Penn Discourse Treebank 3.0 (PDTB 3.0; Prasad et al. 2019) format of stand-off discourse annotation on plain texts.

Previous versions of discourse annotation of the PDT data were published either separately as versions of PDiT, or as a part of versions of the PDT:

• the Prague Discourse Treebank 3.0 (PDiT 3.0; Synková et al. 2022),
  • largely revised annotation of discourse relations, newly also in the PDTB 3.0 format and sense taxonomy
• the PDT part of the Prague Dependency Treebank - Consolidated 1.0 (PDT-C 1.0; Hajič et al. 2020),
  • fixes of individual errors in the discourse annotation
• the Prague Dependency Treebank 3.5 (PDT 3.5; Hajič et al. 2018),
  • fixes of individual errors in the discourse annotation
• the Prague Discourse Treebank 2.0 (PDiT 2.0; Rysová et al. 2016),
  • discourse relations marked by selected secondary connectives, updated discourse relations marked by primary connectives
• the Prague Dependency Treebank 3.0 (PDT 3.0; Bejček et al. 2013), and
  • genres of documents, updated discourse relations marked by explicit (mostly primary) connectives
  • also, as a part of the underlying data, pronominal textual coreference of 1st and 2nd person
• the Prague Discourse Treebank 1.0 (PDiT 1.0; Poláková et al. 2012)
  • discourse relations marked by explicit (mostly primary) connectives
  • also, as a part of the underlying data, extended textual coreference and bridging anaphora
