Thesaurus with predicate-argument structure to provide base framework to determine states, actions, and change-of-states

The goal with this chapter is to discuss the possibility of language resources in determining the states, actions, and change-of-states of characters in narratives. An overview of previous work on linguistic theory and language resources is given then the Predicate-Argument Structure Thesaurus (PT), a Japanese language resource constructed based on the extended framework of the Lexical Conceptual Structure (LCS), is proposed. The PT provides hierarchical clusters of synonyms for 11,900 predicates and 22,000 example sentences annotated with semantic role labels. Each concept has an abstracted LCS, and example sentences are attached to each concept. By virtue of the structure, a correlation of the arguments between other clusters can be determined. The semantic structure of the PT is investigated to enrich generated texts of narratives, and the high possibility of lexical semantics contributing to narrative processing is revealed.
