-The original morphosyntactic tags have been converted to fit into the three columns (CPOS, POS and FEAT) of the CoNLL format. There //should// be a 1-1 mapping between the [[http://www.bultreebank.org/TechRep/BTB-TR03.pdf|BTB positional tags]] and the CoNLL 2006 annotation. Use [[http://quest.ms.mff.cuni.cz/cgi-bin/interset/index.pl?tagset=bg::conll|DZ Interset]] to inspect the CoNLL tagset. +The syntactic annotation style and the tagset for dependency relations (analytical functions) in GDT has been modeled after the [[http://ufal.mff.cuni.cz/pdt2.0/doc/manuals/en/a-layer/html/index.html|Prague Dependency Treebank]].
- +
-The morphological analysis does not include lemmas. The morphosyntactic tags have been assigned (probably) manually. +
- +
-The guidelines for syntactic annotation are documented in the other [[http://www.bultreebank.org/TechRep/BTB-TR05.pdf|technical report]]. The CoNLL distribution contains the BulTreeBankReadMe.html file with a brief description of the syntactic tags (dependency relation labels).+
