Summary

The Serbian UD treebank is based on the SETimes-SR corpus and additional news documents from the Serbian web.

Annotation Source

• Lemmas: automatic pretagging + manual correction (there's no format/annotation style for this)
• UPOS, features: converted from MULTEXT-East
• Dependency realations: automatic preprocessing + manual correction, all directly in UD.

Data Split

Training data: 80% of pseudorandom documents from SETimes-SR (sentence ids set*) and 13 web news documents (sentence ids news*), comprising 3497 sentences (77,334 tokens).

Development data: 10% of pseudorandom documents from SETimes-SR (sentence ids set*) and 13 web news documents (sentence ids news*), comprising 476 sentences (11,460 tokens).

Test data: 10% of pseudorandom documents from SETimes-SR (sentence ids set*) and 13 web news documents (sentence ids news*), comprising 411 sentences (8,879 tokens).

The corpus is parallel with a subset of UD Croatian-SET. In release 2.4, the Serbian and Croatian treebanks were re-split so that training, development and test sets are compatible (corresponding documents are in the same section in both languages).
