Abstract: Provided is a work machine and a work machine management system that enable more appropriate transmission of information of a high-priority work machine even when there is a large number of work machines. A work machine 10 comprises an information controller 20. The information controller 20 acquires operation information of the work machine 10; receives management server information from a management server 90 provided outside the work machine 10; determines a transmission priority order of the operation information based on content of the operation information and the management server information; and transmits the operation information to the management server 90 or a relay 80 according to the transmission priority order.

Abstract: Provided is a data intermediary system, comprising a processor and a storage unit. The storage unit stores therein usage information indicating usage of services. The processor acquires information indicating a data item that needs to be provided by a user as required by a provider of a first service that the user wishes to use, based on terms of use of the first service, selects a second service from services that the user has used in the past, based on the usage information, extracts a difference between the required data items and data items provided based on terms of use of the second service, outputs information indicating the extracted difference, and controls, when the user has accepted the terms of use of the first service, a flow of data from a provider holding the required data to the provider that provides the first service.

Abstract: A data intermediary system includes a processor and a storage unit. The storage unit stores, for a plurality of services used by a user in the past, provision situation information indicating data for each item of the data provided to a service provider to use the service. The processor acquires information indicating an item of data requested, by the service provider, acquires the provision situation of data of the same item as the item of the data requested by the service provider, determines that an item of the data whose provision situation satisfies a predetermined condition is provided to the service provider, and controls distribution of the data to the service provider that that holds the data of the item determined to be provided.

Abstract: Disclosed is a vehicle information management system 1 for choosing a second vehicle 3B corresponding to a first vehicle 3A by selecting a vehicle having a functional configuration corresponding to that of the first vehicle as a candidate of the second vehicle, and selecting, as the second vehicle, a vehicle having a use environment corresponding to that of the first vehicle from the selected candidates of the second vehicles.
