An information processing apparatus, comprising: an acquisition unit configured to acquire image information of an image of an examination paper, the image information including a plurality of question-answer pair regions and a plurality of partial score regions; a recognition unit comprising: a question-answer pair region detector configured to detect a region in the image for each question-answer pair in the examination paper; and a partial score recognition unit configured to recognize a partial score written in the examination paper from the image; and an associating unit configured to associate each partial score with one of the question-answer pair regions in accordance with relationships between locations of the question-answer pair regions and locations of the partial score regions, wherein the question-answer pair region detector is configured to detect a question-answer pair region by: detecting a density distribution of the image of the examination paper; identifying locations in the image having density peaks in a vertical direction and density peaks in a horizontal direction as projections having a question or an answer to the question written therein; combining a pair of adjacent projections to form a question-answer pair block; and wherein the associating unit is configured to associate each partial score with a question-answer pair block if the partial score satisfies a predetermined condition with reference to the question-answer pair block, and is further configured to output, for each of the question-answer pairs, the partial score that is associated with the question-answer pair; and further comprising a marked result aggregating unit configured to associate the partial scores with the examinee of the examination paper. an acquisition unit configured to acquire image information of an image of an examination paper, the image information including a plurality of question-answer pair regions and a plurality of partial score regions;
