Abstract: A document processing device 100 is provided, the device 100 comprises an accessing part 110, a collecting part 120, a morpheme analysis part 130, an extracting part 140, a storing part 150, and a displaying part 160. The collecting part 120 collects evaluation comments aiming at a certain evaluation subject as a first evaluation comment group from the database 180, and collects evaluation comments, in which these evaluation comments are comments on evaluation subjects other than the said certain evaluation subject by valuers who provided evaluation comments on the said certain evaluation subject as a second evaluation comment group from the database 180. The morpheme analysis part 130 segments sentences included in the said first and second evaluation comment groups into pairs of an attribute having at least one predetermined keyword and an attribute value having at least one part of speech regarding the attribute using a morpheme analysis technique.
