Hereinafter, the specific operation of the information system A in the present embodiment will be described. The conceptual diagram of the information system A is FIG.

Now, the map representation data storage unit 111 stores the map representation data management table shown in FIG. The map representation data management table manages one or more records having "ID", "static attribute value", "dynamic attribute value", and "map representation data".

"ID" is a map identifier. The "static attribute value" is a static attribute value of the map representation data, and here, it has area identification information, a scale ratio of the map representation data, an area of the map representation data, a degree of perfection of the map representation data, and metadata. The area identification information is a set of (latitude, longitude), and since the shape of the map representation data of "ID = M01, M02" is rectangular, the information of the upper left point and the lower right point of the rectangle (latitude, longitude) Has. Further, since there are eight vertices of the map representation data of "ID = M03", the area identification information has eight (latitude, longitude) information. Metadata here is the type of map representation data. The "static attribute value" is information input by the company that operates the information processing device 1.

The "dynamic attribute value" is the dynamic attribute value of the map representation data, and here, it is the user action information. Here, the user action information has "DL number of times", "monthly view number", "average access time", and "evaluation value". The "DL count" is the total number of downloads to one or more terminal devices 2 and displayed on one or more terminal devices 2 so far. The "DL count" may be the total number of downloads to one or more terminal devices 2 so far. The "monthly view number" is the total number of times displayed on one or more terminal devices 2 in the month or the previous month. The "average access time" is an average value of the time displayed on the terminal device 2. The "evaluation value" is an average value of the user's evaluation values.

The "dynamic attribute value" is information acquired by the processing unit 13 of the information processing device 1 using the operation information received from the terminal device 2. That is, the receiving unit 12 of the information processing device 1 receives, for example, the map identifier of the displayed map representation data when the map representation data is displayed on the terminal device 2. Then, the processing unit 13 increments the "DL number" and the "monthly view number" paired with the map identifier by 1. After receiving the map identifier of the displayed map representation data, the processing unit 13 starts measuring the display time using a clock (not shown).

Further, when the map representation data is not displayed on the terminal device 2, the receiving unit 12 of the information processing device 1 receives the information or the map identifier indicating that the map representation data has not been displayed. Then, the processing unit 13 acquires the time when the map representation data is displayed on the terminal device 2 (the time from the start of the measurement of the display time). Then, the processing unit 13 changes the "average access time" using the time required.

Further, the receiving unit 12 of the information processing device 1 receives the map identifier and the evaluation value from the terminal device 2. Then, the processing unit 13 changes the average value of the evaluation values paired with the map identifier.

The "map representation data" here is image data. Needless to say, the "map representation data" may be an image file.

In addition, the storage unit 11 stores information for determining the score of the map representation data. It is assumed that such information is an arithmetic expression here. The calculation formula is the distance between the position indicated by the position identification information and the point representing the map representation data (may be simply called "distance"), scale ratio, area, completeness, metadata, number of DLs, number of monthly views. , Average access time, and evaluation value. The calculation formula is a formula in which the score increases as the distance decreases, the score increases as the scale ratio decreases, and the score increases as the area decreases, and the degree of perfection is high (value of completeness). The higher the number of views, the higher the score. The higher the number of DLs, the higher the score. The higher the number of monthly views, the higher the score. The longer the average access time, the higher the score. This is an expression in which the larger the evaluation value, the larger the score. Further, it is assumed that the storage unit 11 holds the original information of the score corresponding to the metadata. The original information of the score is, for example, "illustration map = 2, old map = 3, approximate map = 1" and the like. Further, the information for determining the score of the map representation data may be a table. The table is a table in which the score is determined once the distance, the scale ratio, the area, the degree of perfection, the metadata, the number of DLs, the number of monthly views, the average access time, and the evaluation value are determined. The information for determining the score of the map representation data is one or two or more of the distance, scale rate, area, completeness, metadata, number of DLs, number of monthly views, average access time, and evaluation value. May be information that determines the score using.

Further, the user information storage unit 112 stores the user information management table shown in FIG. The user information management table is a table that manages one or more user information. The user information includes "user identifier", "user attribute", "history information", and "current information". The "user attribute" is an attribute value of the user, and here, it is "age" and "gender". The "history information" is information related to the history of the map expression data browsed by the user, and here, it has a "browsing date", a "browsing map identifier", and a "browsing time". The "browsing map identifier" is a map identifier of the browsed map representation data. The "current information" is information regarding the map representation data currently being viewed by the user. The "current information" has a "viewing map identifier" and a "browsing time" here. The "viewing map identifier" is a map identifier of the map representation data being browsed.

In addition, the storage unit 11 has a place name position correspondence table shown in FIG. The place name position correspondence table is a table showing the correspondence between the place name information and the position information.

In such a situation, the following four specific examples will be described. A specific example 1 is a case where one or more map representation data is displayed on the terminal device 2 when the position identification information is the position information indicating the current position of the user. A specific example 2 is a case where one or more map representation data is displayed on the terminal device 2 when the position identification information is place name information. A specific example 3 is a case where the user inputs a request instruction for the map expression data to be displayed next when the map expression data is displayed. A specific example 4 is a case where the map representation data for the cache is downloaded to the terminal device 2.
