An information processing apparatus for processing image data including character information, the processing of image data including a process of inserting interpretation information corresponding to the character information. The information processing apparatus includes an image data acquisition unit, an interpretation information retrieval unit, an area information definition unit, and an insertion style determination unit. The image data acquisition unit acquires the image data including the character information composed of a plurality of characters having a first string of characters. The interpretation information retrieval unit retrieves first interpretation information to be attached to the first string of characters. The area information definition unit computes insertable area information on a first insertable area, usable for inserting the first interpretation information, based on coordinate data of characters in the acquired image data. The insertion style determination unit determines an insertion style of the first interpretation information based on the insertable area information.
