In FIG. 7, the user who is the application system 30 is a consulting business, for example, a sales promotion consulting business. The application system 60 of the sales promotion consulting company is connected to the device 70 of the monitor store A. The apparatus 70 of the monitor store A includes an environmental sensor I that measures temperature, and a POS data unit that manages sales of the store A, and transmits temperature and POS data to the application system 60 via the network 90. The POS data is the amount of sales accumulated in the cash register system of the store A, for example, sales products over time and their sales amount. The application system 60 takes in sales products over time, the amount of sales, and temperature data, for example, a temperature at which sales of a product (or service) becomes noticeable at a predetermined temperature, here 25 ° C. And correlation with sales can be obtained.

Further, the application system 60 sends the use side search condition 301 to the search data generation unit 50. The search data generation unit 50 is connected to, for example, the consulting target stores B, C, and D as a provider, and receives provider search data. The consulting target stores B, C, and D have the same configuration as the device 70 of the monitor store A. The search unit 53 of the search data generation unit 50 matches the provider search data 101 with the data of the conversion format table 500.

In the example of FIG. 7, for example, a value 25 (° C.) is input in the item of temperature as the use-side search condition. Next, the procedure processing of the sales promotion consulting in (1) to (3) in the figure will be described.

(1) The sales promotion consulting business operator receives provision of sales data (POS data) and environmental sensing data such as the temperature in the store from the device 70 of the monitor store A which has a monitor contract with the company, and the monitor store A The analysis data on the correlation between product sales and in-store environment is held from sales data and environmental sensing data. In this example, it is assumed that when the store internal temperature is 25 ° C., there is a correlation with the increase in sales of a specific product (service).

(2) At the next stage, the sales promotion consulting business operator is sensing data of environmental sensor II (81, 82, 83) installed in the consulting target stores (B, C, D, ...) contracted with the company. The sales promotion support is performed while acquiring the matching with the temperature information by the search unit 53 here.

When there is no reception of the use side search condition 301, this flow is passed, and when there is reception of the use side search condition 301, extraction of input data is performed from among the use side search conditions 301 (step S3). Next, the extracted input data is written to the corresponding item of the conversion format table 500 for sensing data (step S5).

The writing of input data that is the use side search condition 301 from the application system 30 side that is the use side to the corresponding item of the conversion format table 500 for conversion of sensing data is not limited to the manner in which the contents are transferred as it is. As shown in, the aspect may be such that the operation result obtained through the conversion equation is written. Alternatively, the relationship between the data (metadata) on the sensing device 20 and the sensing data in relation to the observation target is associated in advance with the related items of the conversion format table 500, and the use side search condition 301 is used. When the item to be input is input, the search condition may be written according to the association content. Furthermore, relevant information (specifications of the sensing device 20, etc.) is collected by performing a keyword search (browse) or the like on the related site (data server) on the network 90 for the contents input as the user-side search condition 301. If matching is performed in association with the corresponding item of the conversion format table 500, the search accuracy is further improved compared to the input operation.

In step S7, the provider search data 101 is fetched (step S7), and then a search, that is, a matching process is performed (step S9). Then, a process according to the matching result is executed (step S11). For example, when the matching is established, the matching sensing device 20 and the sensing data are transmitted to the use side which is the search request source of the application system 30. Further, the establishment of the matching is notified to the provider of the sensor network unit 10 that has created the provider-side search data 101. On the other hand, when the matching is not established, the fact may be transmitted to the user who is the search request source.
