The PropBank dataset (or, Proposition Bank) [1] is annotated with Semantic Role Label.
The dataset is available via Language Data Consortium (LDC) [2].
Semantic role label of the PropBank is predicate-argument relation. Each sentence in the text of the original Penn Treebank is annotated with a set of semantic roles defined for each verb. For example,
Ex: [Arg0 He][ArgM-MOD would][ArgM-NEG n't]accept [Arg1 anything of value][Arg2 from those he was writing about]. (wsj_0186)
Frameset '''accept.01''' "take willingly" Arg0: Acceptor Arg1: Thing accepted Arg2: Accepted-from Arg3: Attribute
Hand-checked syntactic parse trees are available since annotation was performed on the Penn Treebank corpus.
