Information Processing Device, Information Processing Method, And Information Processing Program

Abstract: An information processing device (1) equipped with: a morphological analysis unit (12) for acquiring object spacetime information (A1) that includes spacetime information indicating the coordinates of a plurality of objects in spacetime and the name of each of the plurality of objects, and for carrying out a morphological analysis, which is a process for deconstructing the names of the plurality of objects included in the object spacetime information (A1) into one or more words, thereby generating morphologically analyzed object spacetime information (A2); a peripheral object information acquisition unit (13) for acquiring morphologically analyzed names (A3) of peripheral objects, which are objects existing at the periphery of each of the plurality of objects in spacetime, from the morphologically analyzed object spacetime information (A2); a peripheral object name word distribution calculation unit (14) for calculating a peripheral object name word distribution (A4) from the morphologically analyzed names (A3), the peripheral object name word being a word included in the name of each of the peripheral objects at the periphery of the plurality of objects; and spacetime information-encompassing distributed expression conversion unit (15) for converting the peripheral object name word distribution (A4) into a spacetime information-encompassing distributed expression (A5) for the word.
