 České značky PDT (přes 4000 značek; jádro Intersetu vzniklo jako vedlejší produkt, když jsem dělal tohle) asi 2 dny, tedy dejme tomu 18 hodin. Dalších 11:09 hodin jsem spotřeboval, když jsem začal ovladače testovat a musel jsem tenhle opravovat. Opět platí, že část času zabralo ladění testovacího skriptu, který v té době teprve vznikal.
-==== CoNLL (derived from PDT) ====
+==== CoNLL 2006 ====
 The CoNLL 2006 and 2007 Czech treebanks are data from PDT converted to the CoNLL format. The PDT morphological tags have been decomposed into coarse-grained part of speech, detailed part of speech, and a set of feature values. All PDT tags have unique equivalents in CoNLL. However, the mapping to the original PDT tags is not one-to-one. Some information, encoded in lemmas in the PDT, has been encoded as a new feature called ''Sem'' in CoNLL data. README refers the following documentation: [[http://ufal.mff.cuni.cz/pdt/Corpora/PDT_1.0/References/mman.html#pos-tag|part of speech and most features]] | [[http://ufal.mff.cuni.cz/pdt/Corpora/PDT_1.0/References/mman.html#sem-info|lemma features]]
@@ Line 58: / Line 79: @@
 More than half of the time was consumed during testing for tuning tags containing the Sem feature.
+==== CoNLL 2009 ====
+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 ''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.

+==== Multext ====
+The tagset of the MULTEXT-EAST project and corpora. The file ''mte-lex/wfl-cs.tbl'' contains 1428 unique tags (which is not to say that other tags are not possible). The corpora are stored in a TEI-compliant SGML format. It is easily readable except that non-ASCII characters are encoded using SGML entities.

+Czech tagsets are notoriously complex. This one maps quite nicely to DZ Interset features. However, the few distinctions that are not (yet) represented in DZ Interset made debugging difficult. Clitic_s and generic numerals represented using the ''other'' feature led to wrong feature-value combinations in conversions to/from other Czech sets. DZ Interset had to be slightly modified in response to this tagset, and more changes that initiated here will be done later.
+==== Prague Spoken Corpus ====
+The Prague Spoken Corpus (Pražský mluvený korpus, PMK) is distributed together with the frequency dictionary of spoken Czech (book). It uses very strange tags and very many of them (over 10000!) Extremely high portion of the tags has to rely on the ''other'' feature. There are two types of tags: long and short.
