 The [[:format-conll|CoNLL data format]] has changed. Formerly (2006 and 2007) there were three relevant columns (coarse-grained part of speech, fine-grained part of speech, and features) that we combined (using tabs) into one tag string. As of 2009, there are only two columns left, namely part of speech and features. For the Czech tags this further means that there is a new feature in the 'features' column. It is called ''SubPOS'', it is present in all tags and its value is one character, copied from the second position of the standard PDT tag. Otherwise, the tags should be identical to those of CoNLL 2007, including the ''Sem'' feature. The [[:format-conll|CoNLL data format]] has changed.

 +The ''Sem'' feature can have more values than previously. This is caused by the extension of the [[http://ufal.mff.cuni.cz/~zeman/publikace/2005-01/mmanual.html#lemma-term|term value set]] in the Prague Dependency Treebank 2.0 (in contrast to 1.0), so the change actually applied already to CoNLL 2007 data. However, CoNLL 2007 uses the older ''cs::conll'' driver.
