Computer program, computer readable storage device and information processing method for aggregating recursive relationships among items among plural users

摘要

PROBLEM TO BE SOLVED: To provide a content system which enables easy discovery of connection of recursive and indirect relation between items by automatically connecting plural pieces of knowledge and information (especially one in which identification information on items is described in a natural language) about relation between items (other than IDs of users) collected from plural users.SOLUTION: There is provided a computer program for allowing users to input relation between plural items to a computer to make the computer store it. For recursive relation between three or more items identified by using character strings, after a first user inputs relation between a first item and a second item to the computer to make the computer store it, the computer program allows a second user to input the same relation between the second item and a third item to the computer to make the computer store it and expresses the recursive relation between the input first item, second item and third item with display position relation in display on a display device (that may include sound display) connected to the computer.
