A text generation method and a text generation device generate a meaningful text even though the number of input keywords is insufficient. In order to achieve this object, keywords are input to the text generation device. In the text generation device, a Bunsetsu-generation-rule acquisition unit acquires a Bunsetsu generation rule from a corpus and a Bunsetsu-candidate generation unit generates Bunsetsu candidates from the keywords. A text candidate generation unit generates text candidates with assuming a dependency relation among the Bunsetsu candidates. An evaluation unit evaluates the text candidates and outputs text in accordance with the evaluation.
