Currently ship navigators must manually pick up necessary navigational information from many kinds of printed matters. It is very hard and headachy work for them to retrieve the useful information on board. In this paper, we propose an automatic retrieval system for sailing directions, which is composed of a general-purpose database, a retrieval engine and a user-friendly interface. When the user inputs a navigational route in terms of the departure port, altering points and arrival port on the chart shown on their workstation's graphic display by its mouse pointer device, the system can retrieve relevant landmarks for the route. The database of sailing directions for our retrieval system currently contains only data for 'Seto Inland Sea.' When the user selects a landmark of the landmark list on the graphic display, the system can retrieve and show the contents about the selected landmark. Our system can save time considerably compared with manual operation. Moreover, it retrieves relevant navigational information from the database without any omissions.
