HLT-NAACL-06 Tutorial AutomaticSemanticRole Labeling Wen-tau Yih & Kristina Toutanova 15 Proposition Bank(PropBank) Define the Set of SemanticRoles It’s difficult to define a general set of semantic roles for all types of predicates (verbs). In natural language processing, semantic role labeling is the process that assigns labels to words or phrases in a sentence that indicates their semantic role in the sentence, such as that of an agent, goal, or result. 0000010053 00000 n To make this slightly clearer, we are attempting to label the arguments of a verb, which are labeled sequentially from Arg0 upwards.
