Abstract

The present invention is directed to a device and method for providing POI information using POI grouping. According to the present invention, POI objects are collected in a preset POI category, a POI group is generated by grouping some of the POI objects using additional information included in each of the POI objects, related POI objects corresponding to a target POI object corresponding to a request from a user are extracted using the POI group, and information corresponding to the related POI objects is transmitted to the user. Related POI objects are extracted and then information is transmitted in response to a request from a user, and thus information about a location desired by the user is provided in a related group, thereby efficiently providing appropriate information.

First claim

1 . A device for providing Point Of Interest (POI) information, comprising:
a POI storage unit configured to collect POI objects in a preset POI category; a POI grouping unit configured to generate a POI group by grouping some of the POI objects using additional information included in each of the POI objects; and a POI communication unit configured to extract related POI objects corresponding to a target POI object corresponding to a request from a user using the POI group, and to transmit information corresponding to the related POI objects to the user.

2 . The device of claim 1 , wherein the POI communication unit recommends at least one or more POI objects close to a current location of the user among the related POI objects using basic information of the related POI objects; generates at least one or more of price comparison information and preference ranking information for the related POI objects and provides the generated information to the user; generates a related POI list using at least one or more of the basic information of the related POI objects and the additional information; and generates at least one or more of the price comparison information and the preference ranking information using the related POI list.

3 . The device of claim 2 , wherein the basic information is information about the POI objects, and the additional information is information about content of the POI objects based on a type of preset POI category.

4 . The device of claim 1 , wherein the POI grouping unit compares the pieces of additional information included in the POI objects; extracts and groups one or more POI objects having identical or similar additional information among the POI objects; searches for a synonym for the additional information using a thesaurus; and determines POI objects having the synonym as the additional information to be the POI objects having similar additional information.

6 . A device for extracting an area of interest (AOI) using a POI distribution chart, comprising:
a keyword input unit configured to transfer a keyword input in accordance with a specific area; a POI distribution chart calculation unit configured to determine location coordinates set for the keyword transferred via the keyword input unit, and to calculate a Point-Of-Interest (POI) distribution chart with the determined location coordinates as its center; and an area setting unit configured to set an area where a number of POIs is equal to or larger than a predetermined value as an AOI based on the POI distribution chart calculated by the POI distribution chart calculation unit; wherein the device for extracting an AOI using a POI distribution chart further comprises an interface unit configured to transmit and receive information to and from one or more terminals; wherein the keyword input unit receives a keyword, input in accordance with a specific area, from any one of the terminals via the interface unit, and determines the keyword; wherein the POI distribution chart calculation unit determines at least one synonym including a name of an administrative address related to the keyword, determines location coordinates set for the keyword and location coordinates set for the synonym, and calculates a POI distribution chart with the determined location coordinates as its center; wherein the POI distribution chart calculation unit calculates the POI distribution chart by sequentially moving a scan area from first determined location coordinates to second determined location coordinates, sets a first scan area having a predetermined size at the first location coordinates, determines a number of POIs within the first scan area, and sets a second scan area larger than the first scan area when a number of POIs within the first scan area is equal to or larger than a predetermined value; and wherein the area setting unit stores information, including at least any one of a name, a category and additional information mapped to at least one POI included in the AOI, with the information being mapped to the AOI.

7 . The device of claim 6 , wherein the area setting unit;
determines a POI included in the second scan area, connects outer coordinate values of the POI, and sets the connected area as an AOI; differently sets the first scan area based on a size of the specific area; and further comprises a service provision unit configured to provide the AOI and information mapped to the AOI in response to a request from a specific terminal.

14 . A space search service device, comprising:
an area storage unit configured to store area objects corresponding to areas within a map; a POI storage unit configured to store a plurality of POI objects, at least some of which match the area objects; and a search unit configured to, when there is an area object matching a POI object corresponding to an input of a user, make a space search for the POI object and provide an extracted child POI object.

15 . The space search service device of claim 14 , wherein:
the space search extracts a POI object, present within an area corresponding to an area object matching the POI object that is a target for the space search, as a child POI object; the search unit makes a space search for the child POI object and then provides an extracted grandchild POI object when there is an area object matching the child POI object; the space search extracts a POI object matching an overlapping area object as a child POI object when there is the area object whose area overlaps an area object, matching the POI object that is a target for the space search, at a predetermined or higher rate; the POI object corresponding to the input of the user corresponds to a building, and the child POI object corresponds to a floor of the building; and areas within the map corresponding to the area objects are polygonal areas.

16 . The space search service device of claim 15 , wherein the search unit provides a child POI object obtained by excluding a POI object corresponding to a grandchild POI object from the extracted child POI object.
