Abstract
To provide an information processing device, an information processing method and a program capable of coping with even an atypical business form in reading image data of a table having a nest structure to output information of an item of the nest structure.SOLUTION: An information processing device includes: an acquisition part for acquiring image data of a business form including a table composed of a plurality of cells; an extraction part for extracting a ruled line of the table on the image data; a recognition part for recognizing a plurality of cells of the table; a combination specification part for specifying one or more candidates for a combination of a parent cell and a child cell in a parent-child relation in the plurality of recognized cells; a selection part for selecting a combination to be adopted from among candidates on the basis of a positional relation between the parent cell and the child cell and an arrangement state of the ruled line between the parent cell and the child cell; and an output part for outputting information showing the parent cell and information showing the child cell on the basis of the selected combination.SELECTED DRAWING: Figure 2
