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.

First claim

1 . An instruction device comprising:
a provided data acquiring unit configured to acquire provided metadata, which is attribute information relating to one or more attributes of sensing data to be output from a sensor, the provided metadata having one or more hierarchy levels that contain information shared by a plurality of sensors; a provided data storage unit configured to store the provided metadata; a usable data acquiring unit configured to acquire usable metadata, which is attribute information relating to one or more attributes of an application that uses sensing data to provide a service; a usable data storage unit configured to store the usable metadata; 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, which is a sum of the inter-level matching degrees of all of the hierarchy levels; a matching result storage unit configured to store the overall matching degree; and an instruction unit configured to transmit a data flow control instruction that specifies the application that corresponds to the usable metadata and the extracted sensor based on the overall matching degree, to a managing device, which manages control of transmitting data of a predetermined sensor to a predetermined application.

2 . The instruction device according to claim 1 ,
wherein the matching unit includes:
a hierarchical data checking unit configured to check an identification sign contained in the provided metadata, the identification sign indicating a link to another hierarchy level;
a hierarchical data acquiring unit configured to acquire provided metadata of the hierarchy level that corresponds to the identification sign from the provided data storage unit; and
a hierarchical data matching unit configured to perform matching between the provided metadata of the sensor acquired for each hierarchy level and the usable metadata, and calculate the inter-level matching degree.

3 . The instruction device according to claim 1 ,
wherein, before calculating an inter-level matching degree of matching between given provided metadata and given usable metadata, the matching unit checks whether or not a corresponding calculated inter-level matching degree is stored in the matching result storage unit, and if it is confirmed that the corresponding inter-level matching degree is stored, calculation of a matching degree of the matching is omitted.

4 . The instruction device according to claim 1 ,
wherein the matching unit performs matching between the provided metadata and the usable metadata for each hierarchy level, calculates, for each sensor, an overall matching degree indicating a matching degree of the matching with the usable metadata based on the inter-level matching degrees, and extracts a sensor capable of providing the sensing data that satisfies a request of the application based on the overall matching degree, and the matching result storage unit stores the overall matching degree of the matching with the usable metadata for each sensor, and the instruction unit transmits a data flow control instruction that specifies the application that corresponds to the usable metadata and the extracted sensor, based on the overall matching degree.

5 . The instruction device according to claim 1 ,
wherein the provided data acquiring unit acquires the provided metadata by acquiring metadata, which is attribute information relating to one or more attributes of the sensing data, from a plurality of sensors, classifying the acquired metadata into pieces of metadata that contain information shared by the plurality of sensors, and hierarchizing the metadata acquired from the plurality of sensors such that each of the pieces of metadata corresponds to any of the one or more hierarchy levels, and the lower the hierarchy level is, the smaller the number of sensors to which the metadata corresponds is.

6 . The instruction device according to claim 1 ,
wherein the hierarchy includes one or more tree structures with one or more branches derived from the highest hierarchy level, the highest hierarchy level corresponds to one piece of provided metadata shared by a plurality of sensors, the one or more tree structures being such that the lower the hierarchy level is, the smaller the number of sensors to which the metadata specific thereto corresponds is, and the lowest branch is in the lowest hierarchy level corresponding to provided metadata specific to one sensor.

7 . An instruction system comprising:
a hierarchization device; and an instruction device, wherein the hierarchization device is configured to acquire metadata, which is attribute information relating to one or more attributes of sensing data to be output from a sensor, from a plurality of sensors, classify the acquired metadata into pieces of metadata that contain information shared by the plurality of sensors, and hierarchize the metadata acquired from the plurality of sensors such that each of the pieces of metadata corresponds to any of the one or more hierarchy levels, and the lower the hierarchy level is, the smaller the number of sensors to which the metadata corresponds is, and the instruction device includes:
a provided data acquiring unit configured to acquire provided metadata, which is attribute information relating to one or more attributes of sensing data to be output from a sensor, the provided metadata having one or more hierarchy levels that contain information shared by a plurality of sensors;
a provided data storage unit configured to store the provided metadata;
a usable data acquiring unit configured to acquire usable metadata, which is attribute information relating to one or more attributes of an application that uses sensing data to provide a service;
a usable data storage unit configured to store the usable metadata;
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, which is a sum of the inter-level matching degrees of all of the hierarchy levels;
a matching result storage unit configured to store the overall matching degree; and
an instruction unit configured to transmit a data flow control instruction that specifies the application that corresponds to the usable metadata and the extracted sensor based on the overall matching degree, to a managing device, which manages control of transmitting data of a predetermined sensor to a predetermined application.

8 . An instruction method comprising the steps of:
acquiring provided metadata, which is attribute information relating to one or more attributes of sensing data to be output from a sensor, the provided metadata having one or more hierarchy levels that contain information shared by a plurality of sensors; acquiring usable metadata, which is attribute information relating to one or more attributes of an application that uses sensing data to provide a service; performing matching between the provided metadata obtained from a provided metadata storage unit in which the provided metadata is stored and the usable metadata obtained from a usable metadata storage unit in which the usable metadata is stored for each hierarchy level, calculating, for each hierarchy
