-This is an overview of existing tag set drivers. Tag-set or language specific issues are described here.+This is an overview of existing tag set drivers. Tag-set or language specific issues are described here. I also try to keep track of the work time needed for particular drivers because the original motivation behind DZ Interset was to save time and effort.
  
-===== Chinese =====+===== Arabic (ar) ===== 
 + 
 +==== CoNLL 2006 ==== 
 + 
 +The Arabic CoNLL tags are derived from the tags of the Prague Arabic Dependency Treebank. 
 + 
 +Created in 2006-2007. 
 +Total work time: 13 hours 
 + 
 +==== CoNLL 2007 ==== 
 + 
 +The Arabic tags in CoNLL 2007 slightly differed from 2006. There are also new tags. The driver ''ar::conll2007'' was cloned from ''ar::conll'' and modified. 
 + 
 +Created: 23.6.2011 
 +Total work time: 2 hours 
 + 
 +===== Bulgarian (bg) ===== 
 + 
 +The Bulgarian CoNLL tags are derived from the tags of BulTreeBank. Speciality: sophisticated system of pronouns includes interrogative adverbs and numerals. 
 + 
 +Created in 2007. 
 +Total work time: 35 hours 
 + 
 +The main reasons why the implementation took so long: 
 +  * Necessity to re-work the system of main word classes, especially pronouns. 
 +  * Necessity to separate morphological and lexical definiteness (there are indefinite pronouns morphologically definite, and vice versa). 
 +  * Necessity to separate morphological and lexical aspect (aorist vs. imperfect tense; there are perfective verbs that can occur in imperfect tense). 
 +  * Driver tester required that encode(decode(x))=x. However, the CoNLL incarnation of the tags was inconsistent, in the order and form in which it presented features. 
 + 
 +===== Chinese (zh) =====
  
 The only corpus covered so far is the Sinica Treebank, converted to the CoNLL format. The tag set lacks comprehensive documentation (almost zero supplied with CoNLL data, and only a little found in the web). The tags do not encode any morphological features. Instead, there is a comprehensive (but undocumented) hierarchy of word classes and subclasses. Most of the information encoded in the tags cannot be mapped to Interset. The only corpus covered so far is the Sinica Treebank, converted to the CoNLL format.

-===== Time needed for tag set conversion =====+===== Croatian (hr) =====
  
-Poznamenávám si, kolik času mi zabral který ovladač, abych to mohl publikovat. Srovnání potřebného času s časem potřebným na obyčejný převod je zajímavé, i když vím, že ve skutečnosti ušetřím až při opakovaném využití ovladače.+==== Multext ====
  
-Ruský treebank (nejen značky, ale vůbec převod formátu): +The tagset of the MULTEXT-EAST project as used in the SETimes.HR corpus. Documentation lists 1291 tags, we removed one wrong tag and kept 1290.

-4:45+1+1:40 = 7:25+Work finished: 17.7.2014 
 +Total work time: 5:45 h
  
-České značky PDT (přes 4000 značek; jádro Intersetu vzniklo jako vedlejší produkt, když jsem dělal tohle) +This is the second Multext-East tagset covered by DZ Interset. Adding it was not too difficult because much of the previous effort on ''cs::multext'' could be reused.
-asi 2 dny, tedy dejme tomu 18 hodin+
  
-Dánské značky DDT/Parole (144 značek s košatým popisem) +===== Czech (cs) =====
-asi 7 hodin+
  
-Švédské značky Mamba (48 značek) +==== Prague Dependency Treebank (PDT) ====
-asi 3 hodiny+
  
-Penn Treebank (36 značek) +Při práci na tomto ovladači jsem ještě neměl k dispozici chytré funkce pro zajištění povolených značek.
-asi 3 hodiny, ale tady jsem to ještě neměřil, takže to je jen hrubý zpětný odhad+
  
-Hajičovy švédské značky +Jde zatím o nejrozsáhlejší sadu značek, se kterou jsem se setkal. Obsahuje 4288 značek.
-0:32 - tady zjevně chybí úplná statistika+
  
-Arabské značky CoNLL +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.
-4:33+5:19+3:16 = 13:08+

-1:44+3:20+6:05 = 11:09+
  
-Bulharské značky CoNLL +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]]

-(ale u bulharštiny jsem se dost natrápil s jevy, které do té doby nebyly v intersetu podchycené)+
  
-Anglické značky CoNLL +The list of tags of this tagset contains equivalents of all original PDT tags. In addition, it contains those tags with the ''Sem'' feature set, that occur in CoNLL data, and a few more. The ''Sem'' values are currently stored in the ''other'' feature of Interset. At the same time, ''subpos = "prop"'' is set if ''Sem'' is set and ''subpos'' would otherwise be empty. (The original PDT tags cannot distinguish proper from common nouns.) If the encoder encounters ''subpos = "prop"'', it uses the default value "Sem=m". The "few more" tags were added to the list whenever there was a tag ''Foo=bar|Sem=something'' and there was not the default ''Foo=bar|Sem=m''.
-0:48 - možná tady chybí statistika, ale možná taky ne, protože stačilo upravit existující ovladač Penn Treebanku, ne?+
  
-Žádné z výše uvedených převodů (tedy vše napsané před říjnem 2007) ještě neměly k dispozici chytré funkce pro nahrazování nepovolených hodnot.+Work started: 25.3.2008 
 +Work finished: 25.3.2008 
 +Total work time: 6:02 h 
 + 
 +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. 
 + 
 +Work started: 24.3.2009 
 +Work finished: 24.3.2009 
 +Total work time: 1:10 h 
 + 
 +==== 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. 
 + 
 +Work started: 16.2.2009 
 +Work finished: 18.2.2009 
 +Total work time: 16:36 h 
 + 
 +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. 
 + 
 +Work started: 26.11.2009 
 +Work finished: 4.10.2010 
 +Total work time: 57 hours 
 + 
 +===== Danish (da) ===== 
 + 
 +Tags of the Danish Dependency Treebank converted to CoNLL format. 144 tags with complex documentation in Danish. 
 + 
 +Total work time: about 7 hours 
 + 
 +===== English (en) ===== 
 + 
 +==== Penn Treebank Tagset ==== 
 + 
 +Penn Treebank (45 atomic tags). Detailed classification of punctuation. 
 + 
 +Total work time: about 3 hours 
 + 
 +==== CoNLL 2006 ==== 
 + 
 +The driver is just an envelope around the ''en::penn'' driver. 
 + 
 +Total work time: 48 minutes 
 + 
 +==== CoNLL 2009 ==== 
 + 
 +Another envelope around the ''en::penn'' driver. However, three new tags required changes even in the older drivers: ''HYPH'', ''AFX'' (''PRF'') and ''NIL''. 
 + 
 +Work started: 25.3.2009 
 +Work finished: 25.3.2009 
 +Total work time: 2:57 h 
 + 
 +===== German (de) ===== 
 + 
 +==== Stuttgart-Tübingen Tagset (STTS) ==== 
 + 
 +This is the tagset used in the Tiger treebank. It is quite syntax-oriented, often the same word can be tagged in couple different ways according to its function in a particular sentence. Pronouns are systematically categorized as substitutive (occur instead of an NP), attributive (occur inside an NP) and adverbial. 
 + 
 +The tags omit inflectional information (number and case of pronouns and articles, degree of comparison of adjectives, tense (Präteritum, Konjunktiv), person and number of verbs). 
 + 
 +Work started: 29.3.2008 
 +Work finished: 29.3.2008 
 +Total work time: 4:00 h 
 + 
 +==== CoNLL 2006 ==== 
 + 
 +Only simple envelope around the STTS driver needed. 
 + 
 +Work started: 31.3.2008 
 +Work finished: 31.3.2008 
 +Total work time: 10 min 
 + 
 + 
 +==== CoNLL 2009 ==== 
 + 
 +This tagset is derived from the STTS, too. Unlike CoNLL 2006, there are also morphological features this time, which required additional processing effort. 
 + 
 +Work started: 5.4.2009 
 +Work finished: 6.4.2009 
 +Total work time: 9:39 h 
 + 
 +===== Polish (pl) ===== 
 + 
 +Based on the [[http://korpus.pl/index.php|Korpus Języka Polskiego IPI PAN]]. (Saša tyhle značky potřebuje zpracovat v Intercorpu.) Moderate amount of new stuff but it is one of the fairly complex Slavic tagsets. And it contributed to [[how-to-write-a-driver#replacing-and-the-other-feature|new treatment of o-tags]] (those setting the ''other'' feature) when learning permitted feature-value combinations. 
 + 
 +Work started: 4.9.2009 
 +Work finished: 8.9.2009 
 +Total work time: 9:54 h 
 + 
 +===== Portuguese (pt) ===== 
 + 
 +The Portuguese CoNLL treebank contains tags with 149 different features. Big part of them are noise, probably introduced by the conversion procedure from the original Floresta format to the CoNLL format. The driver is designed so that it accepts all incorrect tags on decoding but encodes only corrected tags. Incorrect tags are not on the list of possible tags so the driver tester will not complain.

 +http://en.wikipedia.org/wiki/Portuguese_grammar 
 + 
 +Work started: 2.4.2008 
 +Work finished: 24.4.2008 
 +Total work time: 28:18 h 
 + 
 +The CoNLL version of the Floresta tagset was a real pain. Not only is the tagset complex with many features, some of them strangely overlapping, some of them undocumented. There was also a terrible proportion of noise, typos or otherwise introduced errors in annotation.
