Spatiotemporal (or 4D) representation and reasoning (or computation in general) has been one of the most prominent themes in AI, especially in terms of progress in cognitive robotics, and a considerable number of approaches have been reported. However, they are quite objective, that is, not based on a certain plausible model of human cognition of 4D world such that it can produce and understand intuitive or subjective 4D expressions in natural language. This paper describes 4D language understanding based on Mental Image Directed Semantic Theory, focusing on intuitive 4D representation and reasoning.
