comp and extensions #

Universal #

The comp relation is used for arguments of verbs, nouns, adjectives, adverbs, auxiliaries, adpositions and conjunctions.

This relation is refined into several extensions:

• comp:aux (auxiliary argument)
• comp:cleft (cleft clauses)
• comp:obj (direct object)
• comp:obl (oblique argument)
• comp:pred (predicative argument)

In most cases, SUD native corpora are directly annotated with the extensions, rather than with the comp relation. However, comp may sometimes be used when one has difficulty deciding between comp:obj and comp:obl.
