Abstract

Provided is an information processing apparatus that extracts a character string to be a candidate of an item value corresponding to a predetermined item, from among multiple character strings included in a document image to be processed. The information processing apparatus first obtains information indicating a conceptual feature group of a preset extraction target, then identifies a conceptual feature group to which each of the character strings included in the document image to be processed belongs from among predetermined multiple conceptual feature groups based on a feature vector corresponding to each character string, and then extracts the character string whose identified conceptual feature group is the same as the conceptual feature group associated with the same attribute information as the conceptual feature group of the extraction target, from among the character strings included in the document image, as the candidate.
