To provide an information processing device that improves work efficiency of a user who checks and corrects information extracted from a document.SOLUTION: An image processor 100 extracts a character area from a scan image of a document, performs character recognition on the character area, and extracts, using a result of the character recognition, an item name candidate and an item value candidate. Then, the image processor 100 extracts, based on a predetermined positional relation between the item name and the item value, a candidate for a pair of item name and item value, and performs, when candidates for a pair of item name and item value that should be one or more are not extracted, a re-search to extract the candidate for a pair of item name and item value. After that, the image processor 100 displays the extracted candidate for a pair of item name and item value. In this case, the image processor 100 switches a display method between the candidate for a pair of item name and item value obtained before the re-search and the candidate for a pair of item name and item value obtained by the re-search.SELECTED DRAWING: Figure 2
