Abstract: A circuitry estimates a degree of interest in each of destination candidates for each of subject users included in a user group determined based on degree of affinity among multiple users. The circuitry sets a location in which the degree of interest of a first one of the subject users is greater than or equal to a predetermined degree-of-interest threshold value as a first destination. The circuitry provides a second one of the subject users with a first trip proposal when the degree of interest of the second user in the first destination is greater than or equal to the predetermined degree-of-interest threshold value. The circuitry provides the second user with a second trip proposal when the degree of interest of the second user in the first destination is less than the predetermined degree-of-interest threshold value.

Abstract: A proposal subject determination unit selects, from multiple users, a combination of users of which the degree of affinity is a first degree-of-affinity threshold value or greater and determines that the users included in the selected combination are subject to the trip proposal. A proposal execution unit sets a location in which a degree of interest of a first one of the subject users is greater than or equal to a predetermined degree-of-interest threshold value as a destination of the trip proposal and provides the trip proposal having the set location as a destination to the subject users. The proposal execution unit gives a first trip proposal or a second trip proposal to a second user in accordance with a degree of affinity between the subject users, a degree of interest of the second user in the set location, and a trip preference of the second user.
