Abstract

A provider-side metadata acquisition part acquires provider-side metadata regarding a sensing data providing terminal. The provider-side metadata includes a current position of the sensing data providing terminal. Also, the user-side metadata acquisition part acquires user-side metadata regarding sensing data using terminal. A matching part performs matching with the user-side metadata, using the current position of the sensing data providing terminal included in the provider-side metadata and the current time, and decides whether to request the sensing data providing terminal to provide the sensing data. A request part requires the sensing data providing terminal to provide the sensing data in accordance with the decision by the matching part.

First claim

1 . A matching apparatus comprising:
a provider-side metadata acquisition part configured to acquire provider-side metadata regarding a first terminal that provides sensing data, the provider-side metadata including at least a current position of the first terminal; a user-side metadata acquisition part configured to acquire user-side metadata regarding sensing data that is to be used by a second terminal; a matching part configured to perform matching with the user-side metadata, using the current position of the first terminal included in the provider-side metadata and the current time, and decide whether to request the first terminal to provide the sensing data; and a request part configured to request the first terminal to provide sensing data, based on the decision by the matching part.

2 . The matching apparatus according to claim 1 ; wherein
the first terminal includes a position measurement part configured to measure a position of the first terminal, and the current position of the first terminal included in the provider-side metadata is a position of the first terminal measured by the first terminal using the position measurement unit.

3 . The matching apparatus according to claim 1 , wherein
the user-side metadata includes a content of the sensing data, an acquisition position of the sensing data, and an acquisition time of the sensing data, and if the difference in time between:
the time when the first terminal reaches a position, where the distance of the first terminal from the sensing data acquisition position included in the user-side metadata is shorter than or equal to a first setting distance, and
the sensing data acquisition time included in the user-side metadata is within a first setting time period, then the matching part decides to request the first terminal to provide the sensing data.

4 . The matching apparatus according to claim 3 ; wherein
the request part is configured to separately request the first terminal to provide:
first sensing data in which the difference in time between the time when the first terminal reaches a position, where the distance of the first terminal from the sensing data acquisition position included in the user-side metadata is shorter than or equal to a second setting distance which is shorter than a first setting distance, and the sensing data acquisition time included in the user-side metadata, is within a second setting time period which is shorter than a first setting time period, and
second sensing data other than the first sensing data.

5 . The matching apparatus according to claim 3 ; wherein
when requesting the first terminal to provide the sensing data as determined by the matching part, the request part notifies the first terminal of a content of the sensing data, an acquisition position of sensing data, and an acquisition time of the sensing data.

6 . The matching apparatus according to claim 1 , further comprising:
a user-side metadata storage part configured to store user-side metadata regarding sensing data that is to be used by the second terminal, and the user-side metadata acquisition part reads out the user-side metadata from the user-side metadata storage part.

7 . The matching apparatus according to claim 1 , further comprising:
a communication unit configured to receive the user-side metadata that is transmitted from the second terminal and is regarding sensing data that is to be used by the second terminal.

8 . The matching apparatus according to claim 1 , wherein
the provider-side metadata includes a movement schedule of the first terminal, and the matching part is configured to perform matching with the user-side metadata, and to decide whether to request the first terminal to provide the sensing data, using the movement schedule of the first terminal included in the provider-side metadata as well.

9 . A terminal comprising
a display control part for displaying a screen in accordance with a request from the matching apparatus according to claim 4 , for providing sensing data wherein the display control part displays a screen in which a request for providing the first sensing data and a request for providing the second sensing data are separate.

10 . A sensor network system comprising:
the matching apparatus according to claim 1 , the first terminal, and the second terminal, wherein the matching apparatus, the first terminal, and the second terminal are connected to one another via a network so that they can communicate digitally with each other.

11 . A matching method wherein a computer executes steps comprising:
a provider-side metadata acquisition step of acquiring provider-side metadata regarding a first terminal that provides sensing data, the provider-side metadata including at least a current position of the first terminal, a user-side metadata acquisition step of acquiring user-side metadata regarding sensing data that is to be used by a second terminal, a matching step of performing matching with the user-side metadata, using the current position of the first terminal included in the provider-side metadata and the current time, and deciding whether to request the first terminal to provide the sensing data, and a request step of requesting the first terminal to provide the sensing data in accordance with the decision in the matching step.

12 . A matching program for causing a computer to execute:
a provider-side metadata acquisition step of acquiring provider-side metadata regarding a first terminal that provides sensing data, the provider-side metadata including at least a current position of the first terminal, a user-side metadata acquisition step of acquiring user-side metadata regarding sensing data that is to be used by a second terminal, a matching step of performing matching with the user-side metadata, using the current position of the first terminal included in the provider-side metadata and the current time, and deciding whether to request the first terminal to provide the sensing data, and a request step of requesting the first terminal to provide the sensing data in accordance with the decision in the matching step.

13 . The matching apparatus according to claim 4 ; wherein
when requesting the first terminal to provide the sensing data as determined by the matching part, the request part notifies the first terminal of a content of the sensing data, an acquisition position of sensing data, and an acquisition time of the sensing data.

14 . The matching apparatus according to claim 2 , wherein
the provider-side metadata includes a movement schedule of the first terminal, and the matching part is configured to perform matching with the user-side metadata, and to decide whether to request the first terminal to provide the sensing data, using the movement schedule of the first terminal included in the provider-side metadata as well.

15 . The matching apparatus according to claim 3 , wherein
the provider-side metadata includes a movement schedule of the first terminal, and the matching part is configured to perform matching with the user-side metadata, and to decide whether to request the first terminal to provide the sensing data, using the movement schedule of the first terminal included in the provider-side metadata as well.

16 . The matching apparatus according to claim 4 , wherein
the provider-side metadata includes a movement schedule of the first terminal, and the matching part is configured to perform matching with the user-side metadata, and to decide whether to request the first terminal to provide the sensing data, using th
