1. An information providing device configured to propose a trip to multiple users in parallel, the information providing device comprising:

  • a degree-of-affinity estimation unit configured to estimate a degree of affinity of each of the users with respect to another one of the users;

    a proposal subject determination unit that selects, from the multiple users, a combination of users of which the degree of affinity is greater than or equal to a first degree-of-affinity threshold value and determines that the users included in the selected combination are users that are subject to the trip proposal;

    a degree-of-interest estimation unit configured to estimate a degree of interest in each of a plurality of locations that are destination candidates for each of the subject users;

    a trip preference estimation unit configured to estimate a trip preference that is an index indicating a degree of preference for taking a trip for each of the subject users; and

    a proposal execution unit configured to set 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 destination of the trip proposal and provide the subject users with the trip proposal in which the location is set as the destination,wherein the proposal execution unit is configured to provide a second one of the subject users with a first trip proposal if the degree of affinity between the subject users is greater than or equal to a second degree-of-affinity threshold value, which is greater than the first degree-of-affinity threshold value, when the degree of interest of the second user in the set location is greater than or equal to the predetermined degree-of-interest threshold value and the trip preference of the second user is greater than or equal to a predetermined trip preference threshold value,the proposal execution unit is configured to provide the second user with a second trip proposal if the degree of interest of the second user in the set location is less than the predetermined degree-of-interest threshold value or if the trip preference of the second user is less than the predetermined trip preference threshold value, andin the second trip proposal, a degree of recommendation of the trip proposal is increased from the first trip proposal.
