Abstract
Corpus of contemporary written Czech sized more than 4.2 billion running words (i.e. 5.1 billion tokens). It covers mostly the period of 1990-2017 and it features rich metadata including detailed bibliographical information, revised text-type classification etc.
Although it contains a wide range of text types (fiction, non-fiction, newspapers), the newspapers prevail noticeably. The corpus is lemmatized and morphologically annotated by a combination of stochastic and rule-based methods.
The main difference when compared to its predecessor, SYN v6, lies in the update of the newspaper part (publication year 2017 added).
