Discourse structure analysis system and discourse structure analysis program

摘要

PPROBLEM TO BE SOLVED: To provide a discourse structure analysis system which is robust to characteristics of discourse data of spoken words, noise, etc., and analyzes a structure of discourse data to generate semantics of a discourse structure available for various uses. PSOLUTION: A discourse structure analysis system 1 which receives discourse data 100 to output discourse semantics 200 includes: a flow analysis rule 22 including flow expressions for determining information of flows of respective statements and flow definitions designating flows to be set to statements having expressions matching the flow expressions; and a flow analysis part 20 which performs matching between each statement and respective flow expressions in the flow analysis rule 22 and sets a flow designated by a corresponding flow definition in the flow expression matching the statement to output flow information 21 including the statement and the flow corresponding to each other. The flow information 21 is output as discourse semantics 200. PCOPYRIGHT: (C)2011,JPO&INPIT
