Information processing device and information processing method for judging the semantic relationship between words and sentences
5 Dec 23
An information processing device includes processing circuitry to acquire object spatiotemporal information including spatiotemporal information indicating coordinates of objects in time and space and a name of each of the objects and to generate morphological analysis-undergone object spatiotemporal information by executing a morphological analysis as a process of analyzing the name of each of the 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 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 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.
