1. An information processing device comprising:
processing circuitry
to acquire object spatiotemporal information including spatiotemporal information indicating coordinates of a plurality of objects in time and space and a respective name of each of the plurality of objects and to generate morphological analysis-undergone object spatiotemporal information by executing a morphological analysis as a process of analyzing the respective name of each of the plurality of objects included in the object spatiotemporal information into one or more words;
to acquire morphological analysis-undergone names of vicinal objects, as objects existing in a vicinity of each of the plurality of objects in time and space, from the morphological analysis-undergone object spatiotemporal information;
to calculate a distribution of vicinal object name words, as words included in the names of the vicinal objects of each of the plurality of objects, from the morphological analysis-undergone names; and
to convert the distribution of the vicinal object name words to a spatiotemporal information-considered distributed representation regarding words.
