Title:
INFORMATION REPRESENTATION STRUCTURE ANALYSIS DEVICE, AND INFORMATION REPRESENTATION STRUCTURE ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2022/215433
Kind Code:
A1
Abstract:
The present invention efficiently extracts target information from an atypical document. This information representation structure analysis device: stores an information representation template, which is a template to be used for generating an information representation pattern as a program code for realizing a function of extracting an extraction target, for each combination of information representation grammar and a support information category as a classification of support information that is information for use in extracting the extraction target; identifies an information representation template to be used for generating an information representation pattern for use in extracting an extraction target from an atypical document, on the basis of the information representation grammar and support information category identified for information representation; and generates an information representation pattern by applying the extraction target and basis information, which is information serving as a basis when extracting the extraction target from the information representation, to the identified information representation template.
