The present invention provides a technique capable of generating and providing information in which various elements are associated with one another in accordance with situations. An information processing system has a server and a plurality of terminals. Each of the terminals obtains element associated information obtained by associating elements belonging to items included in a plurality of element items and transmits the element associated information to the server. The server receives the element associated information from each of the terminals. In the case where one or more terminals included in the plurality of terminals satisfies a specific condition, the server generates network information obtained by associating elements belonging to the items between the items on the basis of one or more pieces of element associated information received from the one or more terminals.
