Abstract: 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.

Abstract: A method and an apparatus for measuring the microforce acting between a micro particle fixed on the probe and the observation plane are described. The probe is feedback-controlled to be held motionless by canceling probe displacements caused by movements of the micro particle fixed on the probe, using irradiation pressure provided by a laser that applies photon pressure. The microforce acting between the micro particle fixed on the probe and the observation plane is measured by recording the time-varying laser output power. This allows probe fluctuations to be reduced to a few angstroms, and permits control of the distance to the target object to within a few nm, enabling measurement of microforces on the order of 0.1 pN.
