A record in which “Service A” is set and “ABC12345” is set in the column value of the “Contributor ID” item is added to the table of the user information 103.

[Example of route search processing]
Hereinafter, an example of route search processing by the information presentation apparatus 10 according to the present embodiment will be described with reference to the drawings.
FIG. 6 is a diagram illustrating an example of route search result information 104 stored in the information presentation apparatus 10 according to the first embodiment of the present invention. As shown in the figure, the route search result information 104 is a two-dimensional table composed of columns of five items of “user ID”, “departure place”, “departure time”, “destination”, and “guide route”. Format data.

When a route search request is made in the navigation service provided by the information presentation device 10, the user displays a destination, a departure (scheduled) time, and a route search request screen (not shown) displayed on the display unit 250 of the user terminal 20. And information indicating search conditions. Accordingly, a route search request including information indicating the user ID, the departure place, the departure (scheduled) time, the destination, and the guidance route is transmitted from the user terminal 20 to the information presentation device 10.
The search condition is, for example, a condition related to a movement method (for example, movement by car or movement on foot) and a condition related to a charge (for example, whether to use a toll road). .

  For example, when the user ID is “B0001” and the user at the point “B” starts on the route search request screen displayed on the display unit 250 of the user terminal 20 with the destination “Q” and the departure (planned) ) When “8:12”, which is the time, is input, in addition to the input information, “B0001”, which is the user ID, and “B”, which is the position information indicating the current position acquired by the position information acquisition unit 230. The route search request including the information indicating that is transmitted from the user terminal 20 to the information presentation device 10.

The route search unit 114 of the information presentation device 10 calculates a guide route based on the acquired route search request and the map information 101 and the congestion information 102 stored in the storage unit 100. Then, the route search unit 114 adds information based on the acquired route search request and information in which the calculated guide route is associated with the route search result information 104 stored in the storage unit 100.
For example, “B0001” is set as the value of the “user ID” item and “0” is set as the value of the “departure place” item, as in the record in the third row of the table of the route search result information 104 illustrated in FIG. “B” is set, “8:12” is set as the value of the column of “Departure time”, “Q” is set as the value of the item of “Destination”, and the column of the item of “Guide route” A record in which “B → E → H → L → Q” is set to the value of is added to the table of the route search result information 104.

  Note that “B → E → H → L → Q” set in the value of the column of the “guidance route” item indicates the guidance route calculated by the route search unit 114 and is the departure place “ A guide route indicating a route moving from the “B” point to the “Q” point as the destination through the “E” point, the “H” point, and the “L” point in this order is shown.

Then, the route search unit 114 transmits route information indicating the guidance route to the user terminal 20 via the route information presentation unit 115.
When there is a congested location in the guide route, the route search unit 114 transmits route information including information indicating the congested location to the user terminal 20 in addition to the guide route. For example, when the area between the “E” point and the “H” point is a congested part, the route information transmitted from the information presentation device 10 to the user terminal 20 includes the guidance “B → E → H → L → Q”. Information indicating a route and a congested location “E → H” is included.

  When the user terminal 20 acquires the route information transmitted in the above, the user terminal 20 displays an image indicating a guide route based on the route information on a map of a route guide screen (not shown) displayed on the display unit 250. In addition, when the information which shows a congestion location is contained in route information, the user terminal 20 superimposes and displays the information which shows a congestion location on the image which shows said guidance route, and which area is a congestion location. Is displayed so that the user can easily recognize it.

Note that the above route search process is not executed only when the user makes a route search request on the route search request screen, but is repeatedly executed (re-executed while the user is moving along the route). Search). The re-search is executed, for example, every certain time or every time it passes through a waypoint. The route search result information 104 stored in the storage unit 100 is updated with the point where the re-search is performed as a new “departure place” and the time when the re-search is performed as a new “departure time”. Is done.
It is also possible to consider the departure location as the current location by shortening the interval for updating the departure location by re-searching. Furthermore, even when route search and route guidance are not performed, a method of updating the departure place at the same time as the re-search at a constant interval while the application is running is also possible.

[Execution example of information presentation process]
Hereinafter, an example of information presentation processing by the information presentation apparatus 10 according to the present embodiment will be described with reference to the drawings.
FIG. 7 is a diagram showing an example of a navigation screen displayed on the user terminal 20 according to the first embodiment of the present invention. As shown in the figure, a route is displayed on the navigation screen, and a saddle-shaped (half arrow) line is attached to the left of a part of the route along the route. A section on the route with the saddle-shaped line on the left side represents a congested portion.

  When the user wants to acquire information posted to the posted information sharing service in the vicinity of the crowded area, the user designates the area of the crowded area displayed on the navigation screen (for example, touches the screen). As a result, specified location information including information indicating the specified location (congested location), the user ID, and the current time is transmitted from the user terminal 20 to the information presentation device 10.

The posted information collection unit 123 of the information presenting apparatus 10 accesses the posted information sharing server, and collects posted information whose poster ID is “S0050P” or “XYZ56789” and whose posting time is around 8:30. Then, the posted information analysis unit 124 of the information presentation device 10 analyzes the acquired posted information and edits the posted information.
For example, as described above, the posted information analysis unit 124 totals the appearance frequencies in all the acquired posted information for each word included in the posted content included in the acquired posted information, and the totaled frequency is Posting information including posting contents including a high word / phrase (for example, a word / phrase whose appearance frequency is in the top five or a word / phrase having an appearance frequency equal to or higher than a predetermined height) is preferentially extracted. In addition, for example, the posting information analysis unit 124 includes posting information including specific words (for example, words related to congestion and proper nouns such as names of celebrities reminiscent of occurrence of sudden events). Edits such as extracting or excluding post information including the specific phrase.

  The user terminal 20 acquires post information transmitted from the information presentation device 10 via the communication network 50. Then, the user terminal 20 displays information based on the acquired posting information on the navigation screen displayed on the display unit 250. Below, the example of the display of the information based on contribution information is demonstrated.
