The Unified Linguistic Annotation (ULA) project seeks to integrate into one framework different layers of annotation (e.g., semantics, discourse, temporal, opinions) using various existing resources, including PropBank, NomBank, TimeBank, Penn Discourse Treebank and coreference and opinion annotations. The Unified Linguistic Annotation Text Collection consists of two separate corpora: The Language Understanding Annotation Corpus (LDC2009T10) and REFLEX EntityTranslation Training/DevTest (LDC2009T11).
