Introduction
============

SiR 2.0 is an annotated corpus of Czech articles from a news server of a Czech
public radio iRozhlas (https://www.irozhlas.cz/). It is a collection of
1 718 articles (42 890 sentences, 614 995 words) with manually annotated
attribution. SiR 2.0 is an update of its prior release, SiR 1.0, bringing
expert annotation to two (out of three) original data parts.

For example, in the sentence:
Premiér prohlásil, že platy vzrostou o 10 %.
[The prime minister has stated that salaries will increase by 10%.],
the citation phrase prohlásil [has stated] refers to the citation source
premiér [the prime minister], who provided the information.

The sources are further classified into several classes of named (official
political, official non-political, unofficial) and unnamed (anonymous,
partially anonymous) sources:

 - official (with mandate, also an institution)
   - official political – e.g., předseda vlády [prime minister], Ministerstvo
                          obrany [Ministry of defence]
   - official non-political – e.g., ředitel Národního muzea [director of National
                              muzeum], mluvčí fotbalového klubu [spokesman of
                              a football club], firma Apple [Apple]
 - unofficial (fully specified, without mandate)
   - unofficial - e.g., kytarový virtuos Lubomír Brabec [guitar virtuoso Lubomír
                  Brabec], bývalý prezident Václav Klaus [former president Václav
                  Klaus], New York Times [New York Times]
