NEW CASE GENERATION DEVICE, NEW CASE GENERATION METHOD, AND NEW CASE GENERATION PROGRAM

摘要

A new case whose type is the same as that of a case about information desired to be extracted can be generated with high accuracy.;A new case generation device according to the present invention includes: new case generating means that receives a case about information desired to be extracted and a case context being text data that includes data on the case and parts present near the case, and generates, on the basis of the received case and the received case context, new cases and new case contexts with the use of document data, the type of the new cases being the same as that of the received case, and the new case contexts being text data that includes data on the new cases and parts present near the new cases and being different from the case context; similarity calculating means that calculates similarities between the case context and the new case contexts; and new case narrowing down means that narrows down, on the basis of the similarities calculated by the similarity calculating means, the new cases generated by the new case generating means and outputs a new case selected by the narrowing-down operation.
