A richly annotated and genre-diversified language resource, The Prague Dependency Treebank – Consolidated 1.0 (PDT-C 1.0, or PDT-C in short in the sequel) is a consolidated release of the existing PDT-corpora of Czech data, uniformly annotated using the standard PDT scheme. PDT-corpora included in PDT-C: Prague Dependency Treebank (the original PDT contents, written newspaper and journal texts from three genres); Czech part of Prague Czech-English Dependency Treebank (translated financial texts, from English), Prague Dependency Treebank of Spoken Czech (spoken data, including audio and transcripts and multiple speech reconstruction annotation); PDT-Faust (user-generated texts). The difference from the separately published original treebanks can be briefly described as follows: it is published in one package, to allow easier data handling for all the datasets; the data is enhanced with a manual linguistic annotation at the morphological layer and new version of morphological dictionary is enclosed; a common valency lexicon for all four original parts is enclosed. Documentation provides two browsing and editing desktop tools (TrEd and MEd) and the corpus is also available online for searching using PML-TQ.
This paper introduces some major conceptual enhancements to the morphological annotation of the SYN series corpora of the Czech National Corpus. Apart from minor changes in tokenization and in the positional tagset, three major conceptual changes have been applied which affect the representation of various lexical and grammatical patterns. In the paper, we present the actual impact of the changes in linguistic data and search for possibilities in three linguistic areas. First, the treatment of phonic, graphemic, and morphological variants via a two-tier lemma structure is discussed; second, a new approach to periphrastic verb forms, auxiliaries, participles and the interpretation of verbal grammatical categories through a new attribute, called verbtag, is explained; and third, a complex multi-value treatment of multiword tokens is introduced.
