Abstract: This invention further enhances the possibility of sensing data being distributed in the case where matching of metadata determines that conditions do not coincide. A data intermediary server 3 performs matching of provider-side metadata transmitted from a sensor management apparatus and user-side metadata transmitted from a data user-side server 2 on an item-by-item basis, calculates scores according to the degree of matching therebetween, and, in the case where the total value of the scores (similarity) does not meet a predetermined first threshold but is greater than or equal to a second threshold, generates provider-side metadata to which the total value of the scores and information on unmatched items of the user-side metadata are appended, and notifies this provider-side metadata to the sensor management apparatus as notification information.

Abstract: An instruction device includes: an acquiring unit configured to acquire provided metadata, which is attribute information relating to one or more attributes of sensing data, the provided metadata having one or more hierarchy levels that contain information shared by a plurality of sensors; an acquiring unit configured to acquire usable metadata, which is attribute information relating to one or more attributes of an application; a matching unit configured to perform matching between the provided metadata and the usable metadata for each hierarchy level, calculate, for each hierarchy level, an inter-level matching degree that indicates a degree of matching in the hierarchy level, and extract a sensor capable of providing the sensing data that satisfies a request of the application, based on an overall matching degree; and an instruction unit configured to transmit a data flow control instruction that specifies the application and the extracted sensor.

Abstract: One mode of the present invention is configured to acquire sensor-side metadata including a first label corresponding to a label showing a name given in order to identify event data, to acquire app-side metadata including a second label that is an event condition showing a condition of an event and corresponds to the label, to determine, in a case where sensing data satisfies a requirement of an application, whether the first label and the second label are identical, and to transmit, in the case where these labels are identical, a dataflow control command including information specifying a sensor, information specifying the application and the event condition included in the app-side metadata.

Abstract: A sensor management unit transmits first sensing data obtained by a first sensor monitoring a target to an external device external to the sensor management unit. The sensor management unit includes a processor, and a memory storing a program. The memory stores obtaining condition information that defines obtaining conditions for obtaining a plurality of candidate items of metadata to be associated with the first sensing data. The program causes the processor to implement obtaining at least one of the candidate items of metadata in accordance with the obtaining conditions and transmitting, to the external device, the obtained first sensing data and the obtained metadata in a manner associated with each other.

Abstract: First and second data catalogs each indicate sensing data attributes. The first and second data catalogs each include a first word indicating an observation object of a sensor that generated sensing data and a second word indicating an observation characteristic of the sensor. A score calculation unit includes a first weight determination part, a second weight determination part, and a score calculation part. The first weight determination part determines a first weight value relating to the observation object, based on the relationship between the first words included in the first and second data catalogs. The second weight determination part determines a second weight value relating to the observation characteristic, based on the relationship between the second words included in the first and second data catalogs . The score calculation part calculates a score relating to the coincidence of the first and second data catalogs, using the first and second weight values.

Abstract: A sensing device management apparatus easily and appropriately generates a data catalog corresponding to sensor metadata. A device information obtaining unit obtains, based on data obtained by a sensing device for performing sensing on a measurement target, an address for obtaining device information about the sensing device, and obtains the device information by accessing the address. A data catalog generation unit generates a data catalog using the device information about the sensing device obtained by the device information obtaining unit.
