In this paper, we present information providing a method to realize semantic representation of train service situations by a combination of sign-logo images. Through this method, multiple images having visual meanings such as pictograms, icons and sign-logos are combined to represent images to express train service situations in the railway space based on the knowledge of the railway company such as transfer ways in accidents. Features of this method are as follows: (1) To express events occurred in railway space by combining multiple images as visual communication based on '5W1H' that corresponds with human communication and information understanding. (2) To dynamically calculate the correlation between an event and meaning of the combined sign-logo images. (3) To be associated with the event of a railway space including an attractive tour guide to foreign visitors by combining sign-logo images. We have developed an experimental system as a digital signage and have applied the method in order to realize a sign-based guide at all train stations for foreign visitors in Japan. The effectiveness and feasibility of this method are shown in this paper.
