-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).

+==== Obtaining and License ====
+The original Penn Treebank is distributed by the LDC under the catalogue number [[http://www.ldc.upenn.edu/Catalog/CatalogEntry.jsp?catalogId=LDC99T42|LDC99T42]]. It is free for LDC members 1999, price for non-members is unknown (contact LDC). The [[http://www.ldc.upenn.edu/Catalog/nonmem_agree/generic.license.html|license]] in short:
+  * non-commercial education and research usage
+  * no redistribution
+  * citation in publications not explicitly required but it is common decency
+The CoNLL 2007, 2008 and 2009 versions are also licensed by the LDC and LDC members can keep them after the shared task. Those who have not participated in the shared task may inquire at the LDC about the availability of the datasets. Their republication in LDC is planned but it has not happenned yet.
+The Penn Treebank was created by members of the [[http://www.cis.upenn.edu/|Department of Computer and Information Science]] (CIS), School of Engineering, University of Pennsylvania, Levine Hall, 3330 Walnut Street, Philadelphia, PA 19104-6309, USA. The constituents-to-dependencies CoNLL 2007 conversion of the treebank was prepared by Ryan McDonald.

+==== Domain ====
+Financial news from the Wall Street Journal (1989). The constituent-based Treebank-3 also contains parsed versions of ATIS-3 and of the Brown Corpus. Only WSJ texts have been converted to dependencies for the CoNLL shared tasks.
+==== Size ====
+Size of CoNLL 2007 data was limited because some teams of CoNLL 2006 complained that they did not have enough time and resources to train the larger models. Sections 2-11 of the Wall Street Journal part of the treebank were used for training and a subset of section 23 was used for testing.

+==== Inside ====
+The original Penn Treebank uses the [[:format-penn|Penn MRG ("merged") bracketing format]]. CoNLL 2007 uses the [[:format-conll|CoNLL-X format]]; CoNLL 2008 and 2009 format is slightly different (number and meaning of columns).
+Conversion for CoNLL 2007: Many function tags were removed from the non-terminals in the phrase-structure representation. The phrase structures were converted to dependency structures using the procedure described in [[http://dspace.utlib.ee/dspace/bitstream/handle/10062/2560/reg-Johansson-10.pdf;jsessionid=BB8432D9BAE4FCF9DD9BD746704E796F?sequence=1|(Johansson and Nugues, 2007)]].
+The original Penn Treebank contains non-terminal labels, function tags and part-of-speech tags, all assigned manually. The CoNLL 2009 version contains manual and automatic disambiguation. See above for documentation of the part-of-speech tags. Use [[http://quest.ms.mff.cuni.cz/cgi-bin/interset/index.pl?tagset=en::penn|DZ Interset]] to inspect the tagset. The original treebank and the CoNLL 2007 version does not contain lemmas. The CoNLL 2009 version includes some lemmas but they are just lowercased word forms most of the time, e.g. nouns are not converted to singular. Nevertheless, there is some base-form normalization of verbs.
