[Problem] To determine, when an expression related to a predetermined subject is present within a document, whether or not an expression related to a predetermined item that should be described in association with the predetermined subject is described within an appropriate range. [Solution] A document data processing device is equipped with: a co-occurrence range setting means for determining a first range on the basis of the distribution in a first document with respect to minimum distance between the appearance position of a predetermined first expression related to a predetermined subject and the appearance position of a predetermined second expression related to a predetermined item that should be described in association with the subject, said first range being the range in which the second expression should be located relative to the appearance position of the first expression in a second document, which is the same document as the first document or a different document; and an insufficient details detection means for detecting that the predetermined item that should be described in association with the subject is not described within an appropriate range when the second expression does not appear within the first range in the second document. |
