Abstract

Provided is a technology that allows use of a trend rating acquired more objectively. A POI information providing device includes: a storage unit which stores POI data including a POI name; a posted data acquisition unit which acquires posted data through a network; a trend rating acquisition unit which obtains a matching degree between a word included in the posted data and the POI name for each piece of the posted data, and uses a predetermined calculation expression for the matching degree to calculate and acquire a trend rating indicating an attention degree of a POI; a trend rating identification unit which identifies, when a request for the trend rating is received from another device connected through the network, the trend rating corresponding to the request; and a transmission unit which transmits the trend rating identified by the trend rating identification unit to the another device.

First claim

What is claimed is:

1. A POI information providing device, comprising:
a storage unit which stores POI data comprising a POI name;
a posted data acquisition unit which acquires posted data through a network;
a trend rating acquisition unit which obtains a matching degree by matching consecutive characters between a word comprised in the posted data and the POI name for each piece of the posted data based on whether the POI name is included in the posted data, and uses a predetermined calculation expression for the matching degree to calculate and acquire a trend rating indicating a trend in popularity of a POI;
a trend rating identification unit which identifies, when a request for the trend rating is received from another device connected through the network, the trend rating corresponding to the request; and
a transmission unit which transmits the trend rating identified by the trend rating identification unit to the another device.

2. A POI information providing device according to claim 1 , wherein:
the POI data has positional information on the POI corresponding to the POI name; and
the trend rating identification unit identifies, based on the request, the trend rating of the POI existing within a predetermined distance from a moving path of the another device.

3. A POI information providing device according to claim 1 , wherein the trend rating acquisition unit identifies, based on a number of the POIs relating to the posted data and whether or not a posted location of the posted data and a location of the POI match each other, the trend rating by using a value obtained by summing up the matching degree obtained for each piece of the posted data for each of the POIs relating to the posted data.

4. A POI information providing device according to claim 1 wherein the trend rating acquisition unit is configured to perform one of multiplication and addition of the trend rating by and to an index defined based on date and time at which the posted data is posted.

5. A POI information providing device according to claim 1 , wherein:
the POI data has a keyword corresponding to the POI name; and
the trend rating acquisition unit is configured to perform one of addition and multiplication of the trend rating to and by a predetermined value in accordance with a number of the keywords comprised in the posted data.

6. A POI information providing system, comprising:
a mobile terminal; and
a POI information providing device which provides the mobile terminal with information relating to a POI,
the mobile terminal and the POI information providing device being connected to each other through a network,
the POI information providing device comprising:
a storage unit which stores POI data comprising a POI name;
a posted data acquisition unit which acquires posted data through the network;
a trend rating acquisition unit which obtains a matching degree by matching consecutive characters between a word comprised in the posted data and the POI name for each piece of the posted data based on whether the POI name is included in the posted data, and uses a predetermined calculation expression for the matching degree to calculate and acquire a trend rating indicating a trend in popularity of the POI; and
a trend rating identification unit which identifies, when a request for the trend rating is received from the mobile terminal, the trend rating corresponding to the request,

the mobile terminal comprising a recommendation degree output unit which outputs a recommendation degree calculated based on the trend rating identified by the trend rating identification unit.

7. A POI information providing system according to claim 6 , wherein:
the POI data stored in the storage unit has positional information on the POI corresponding to the POI name; and
the trend rating identification unit identifies, based on the request, the trend rating of the POI existing within a predetermined distance from a moving path of the mobile terminal.

8. A POI information providing system according to claim 7 , wherein the recommendation degree output unit outputs the recommendation degree calculated based on the trend rating of the POI and a distance from the moving path to the POI.

9. A POI information providing system according to claim 6 , wherein the trend rating acquisition unit identifies, based on a number of the POIs relating to the posted data and whether or not a posted location of the posted data and a location of the POI match each other, the trend rating by using a value obtained by summing up the matching degree obtained for each piece of the posted data for each of the POIs relating to the posted data.

10. A POI information providing system according to claim 6 , wherein the trend rating acquisition unit is configured to perform one of multiplication and addition of the trend rating by and to an index defined based on date and time at which the posted data is posted.

11. A POI information providing system according to claim 6 , wherein:
the POI data has a keyword corresponding to the POI name; and
the trend rating acquisition unit is configured to perform one of addition and multiplication of the trend rating to and by a predetermined value in accordance with a number of the keywords comprised in the posted data.

12. A POI information providing system according to claim 11 , wherein the recommendation degree output unit outputs screen information on a screen which displays the recommendation degree of the POI, the POI name of the POI, and the keyword associated with the POI.

13. A POI information output device, comprising:
a transmission unit which transmits a request for a trend rating indicating a trend in popularity of a POI to a POI information providing device connected through a network; and
a recommendation degree output unit which outputs a recommendation degree calculated based on the trend rating acquired in response to the request,
wherein the transmission unit transmits the request for the trend rating calculated by using a predetermined calculation expression for a matching degree by matching consecutive characters between a word comprised in posted data acquired through the network and a name of the POI based on whether the name of the POI is included in the posted data.

14. A POI information providing method for a POI information providing device comprising a storage unit which stores POI data comprising a POI name,
the POI information providing method comprising:
acquiring posted data through a network;
obtaining a matching degree by matching consecutive characters between a word comprised in the posted data and the POI name for each piece of the posted data based on whether the POI name is included in the posted data, and using a predetermined calculation expression for the matching degree to calculate and acquire a trend rating indicating a trend in popularity of a POI;
identifying, when a request for the trend rating is received from another device connected through the network, the trend rating corresponding to the request; and
transmitting the trend rating identified in the identifying to the another device.
