====== Corpus SYN2013PUB ======

The SYN2013PUB is a synchronic corpus of written journalism, a sequel to [[en:cnk:SYN2006PUB]] and [[en:cnk:SYN2009PUB]]. It contains exclusively journalistic texts from 2005 to 2009, 44 different titles, the total size of the corpus is 935 million of words (tokens). All the [[en:cnk:SYN|SYN-series]] corpora are **disjunctive** as to the texts used, that is no text, which is part of one corpus, is included in another one. Overall size of all the SYN-series corpora thus exceeds 2 200 million text words (tokens).

===== Changes compared to previous journalistic corpora =====
The [[en:pojmy:lemma|lemmatization]] and [[en:pojmy:tag|morphological tagging]] of SYN2013PUB were improved in comparison with the previous corpora. Apart from that, the tagset itself was further simplified in a few cases when the information provided in the tags would be superfluous, hardly recognizable in the context, and thus unreliable. The changes concerned the following:
  * removing number for reflexive pronouns
  * removing possessor's gender for pronouns //jeho//, //jejich//
  * removing person and number for the word form //by//

===== Composition of SYN2013PUB =====

In should be stressed that the SYN2013PUB corpus does not claim to be representative in any way. The main reason for its compilation was a need for more data available in comparable proportions. After inclusion of SYN2013PUB, corpus [[en:cnk:SYN]] in version 3 contains complete volumes of major Czech newspapers from 1998–2009 period. Works on supplementing the synchronic written corpora with newer data are underway.
