This paper firstly discusses three kinds of level in the fineness hierarchy of semantic roles,and introduces their application in some systems of natural language processing(NPL).Then it introduces three approaches to treat semantic roles in three semantic resources for NPL:(i) the frame elements in the semantic frame which is situation based——the semantic roles in the FramNet of California University at Berkeley;(ii) the numbered pro-typical arguments which is special verb based——the semantic roles in the PropBank of Pennsylvania University;(iii) the thematic roles of arguments which is special predicate(verb or adjective) based——the semantic roles in the NetBank of Peking University.Finally,these three semantic resources(i.e.,annotation corpora) are compared from their goals,methodologies,annotation contents and constitutions.
