Every **SYN corpus** contains all the [[en:pojmy:synchronni|synchronic]] [[en:pojmy:psany|written]] corpora of the [[en:cnk:syn|SYN]] series published up until the time of the given version's publication. The corpus SYN version 8 therefore contains the corpora [[en:cnk:syn2000|SYN2000]], [[en:cnk:syn2005|SYN2005]], [[en:cnk:syn2006pub|SYN2006PUB]], [[en:cnk:syn2009pub|SYN2009PUB]], [[en:cnk:syn2010|SYN2010]],[[en:cnk:syn2013pub|SYN2013PUB]] and [[cnk:syn2015|SYN2015]]; additionally, it contains a journalistic component predominantly from the years 2010–2017 (already included into [[en:cnk:syn:verze4|SYN version 4]], [[en:cnk:syn:verze5|SYN version 5]], [[en:cnk:syn:verze6|SYN version 6]] and [[en:cnk:syn:verze7|SYN version 7]]) and as yet **unpublished journalistic texts from 2018** in yearly volume around 150 mil. words.
Because all of these corpora are **disjunctive** (i.e. they do not contain the same texts), the total size of the SYN version 8 is given by their sum, which makes 4.5 billion words ([[en:pojmy:token|tokens]] without punctuation). The SYN corpus is not [[en:pojmy:reprezentativnost|representative]]; the dominant component is journalism, which is the result of the predominance of journalistic corpora [[en:cnk:syn2006pub|SYN2006PUB]], [[en:cnk:syn2009pub|SYN2009PUB]], [[en:cnk:syn2013pub|SYN2013PUB]] and the journalistic component from the years 2010--2018.
The SYN version 8 corpus is [[en:pojmy:referencni|referential]], and will remain accessible to users even after newer versions have been published. It is however necessary to keep in mind that the linguistic information will become outdated, as a natural result of the referential nature of the corpus. Individual versions of the corpus SYN will continue to be published regularly every year with the addition of current journalistic data, and every new addition will be given the attribute value '''' equal to the version of the SYN corpus in which the given text first appeared; for example a [[en:pojmy:subkorpus|subcorpus]] corresponding to the above mentioned (as yet unpublished) journalistic component can be [[en:manualy:kontext:subkorpus#vytvoreni_noveho_subkorpusu|created]] from the SYN version 8 with the help of the condition ''syn="v8"''.

==== Journalism in SYN version 8 ====
The composition of the journalistic part of the corpus SYN version 8 covers the production of most of the national daily newspapers (//Mladá fronta DNES, Lidové noviny, Právo, Hospodářské noviny, Blesk, Sport//), regional daily newspapers (chiefly //Deníky Bohemia// and //Moravia// published by Vltava Labe Media) and non-specialized magazines (//Reflex, Respekt, Týden//) from the years 1998--2018; the total number of journalistic titles is almost 200. The following graphs show the composition of the SYN corpus based on the [[en:pojmy:txtype_group|main text types]] over the years and offer a closer look at the composition of the journalistic section.

====== Structure and annotation of SYN version 8 ======
SYN v8 is identical to its predecessors ([[en:cnk:syn:verze7|version 7]], [[en:cnk:syn:verze6|version 6]], [[en:cnk:syn:verze5|version 5]] and [[en:cnk:syn:verze4|version 4]]) as regards its structure and annotation of texts, i.e. it is based on the [[en:cnk:syn2015#struktura_korpusu_a_strukturni_znacky|hierarchy of structural tags]] and their attributes (e.g. '''' was replaced by ''''), and also on the [[en:cnk:klasifikace_textu_syn2015|classification of texts]] from [[en:cnk:syn2015|SYN2015]], with these two exceptions:
* introducing the additional attribute '''' for the [[en:cnk:syn#reference_corpora_as_subcorpora_in_syn|creation of subcorpora corresponding to the original reference corpora]];
* replacing [[en:pojmy:syntakticka_analyza|syntactic annotation]] in the corpus SYN2015 with a pilot version of **[[en:seznamy:frazemy|phraseme annotation]]**.
