Title:
PREDICATE ARGUMENT STRUCTURE MODIFICATION PROGRAM, PREDICATE ARGUMENT STRUCTURE MODIFICATION METHOD, AND INFORMATION PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/123716
Kind Code:
A1
Abstract:
The present invention enables correction of an estimation error of the range of an argument. An information processing device (10) acquires predicate argument structure information (1) indicating the result of predicate argument structure analysis that analyzes a relation between a predicate and an argument of a sentence to be analyzed. Next, the information processing device (10) performs syntax analysis for the sentence to generate syntax tree information (2) representing, as a syntax tree, the result of the syntax analysis for the sentence. Further, the information processing device (10) compares, for each subtree of the syntax tree represented by the syntax tree information, a correct range candidate indicating the range of words included in the subtree within the sentence with an argument range (4) indicated by the predicate argument structure information. Then, when no correct range candidate of each subtree matches the argument range, the information processing device (10) modifies the argument range in the predicate argument structure information (1) on the basis of the correct range candidate of each subtree.
