====== Corpus SYN2006PUB ======

The SYN2006PUB is a synchronic corpus of written journalism of 300 million of words (tokens). It contains exclusively journalistic texts from November 1989 to the end of 2004, that is the time period covered by corpora [[en:cnk:SYN2000]] and [[en:cnk:SYN2005]]. All three corpora are disjunctive as to the texts used, that is no text, which is part of one corpus, is included in the other two. Corpora [[en:cnk:SYN2000]], [[en:cnk:SYN2005]] and SYN2006PUB thus contain a total of 500 million text words (tokens).

===== Changes compared to the SYN2005 corpus =====

The lemmatization and morphological tagging of the SYN2006PUB corpus have been improved in comparison with the [[en:cnk:SYN2005]] corpus, although the difference is not as striking as in the case of [[en:cnk:SYN2000]] and [[en:cnk:SYN2005]] corpora. The system of morphological tags, the tokenization (division of the corpus into words) and segmentation (division into sentences) remains the same as in the [[en:cnk:SYN2005]] corpus.

===== Composition of the SYN2006PUB corpus =====

In should be stressed that the SYN2006PUB corpus does not claim to be representative in any way. It is clear from the charts below that the corpus composition is balanced neither according to the year of issue, nor according to the titles. The SYN2006PUB corpus will thus be appreciated mainly by users who need to work with large amounts of data.
