Abstract

A map system for presenting Point of Interest (POI) information is provided with an interface module, a storage unit, and a processing module. The interface module is coupled to a display device and provides an operation interface for receiving a search query and a condition of time period. The storage unit stores a plurality of POIs data and verified data of the POIs each corresponding to a respective one of different time periods. The processing module filters the POIs and the verified data according to the search query and the condition of time period to generate an electronic map, and displays the electronic map to present the filtered POIs via the interface module and the display device.

a processing module, collecting original data of the POIs corresponding to the time periods from a plurality of sources, analyzing the original data of each of the POIs corresponding to each of the time periods to generate attribute information for the original data of each of the POIs corresponding to each of the time periods, comparing the generated attribute information with the standard attribute information to determine a number of respective original data whose attribute information matches with the standard attribute information of the respective POI, generating the verified data according to the number of the respective original data, filtering the POIs and the verified data according to the search query and the condition of time period to generate an electronic map, and displaying the electronic map to present the filtered POIs via the interface module and the display device,

wherein the respective original data has an attribute-counted number which exceeds a threshold value, and the attribute-counted number is an amount for the attribute information of the respective original data, which is the same as the standard attribute information of the respective original data.

2. The map system of claim 1, wherein the processing module further performs a semantic analysis for at least one of contents, tags, titles, notations, abstracts, and descriptions of the original data to generate the attribute information.

3. The map system of claim 1, wherein, when the sources comprise social networks and web albums and the original data comprises photographs, checkin information, and geographic information, the processing module further analyzes tags, titles, and descriptions of the photographs, the checkin information, and the geographic information, for the generation of the attribute information.

4. The map system of claim 1, wherein the processing module further performs one of the following for generating the verified data:

using the number of the respective original data as the verified data, and determining the POIs with the verified data which is greater than zero as the filtered POIs;

setting the verified data of a respective POI to indicate that the respective POI has been successfully verified when the number of the respective original data of each of the POIs exceeds another threshold value, and setting the verified data of a respective POI to indicate that the respective POI has not been successfully verified when the number of the respective original data of each of the POIs is less than the another threshold value; and

setting a respective weight for each of the sources, and accumulating products of the number of the respective original data from each of the sources and the corresponding weight, to generate the verified data.

5. The map system of claim 1, wherein the processing module further periodically collects the original data, analyzes the original data for generating the attribute information, and compares the attribute information with the standard attribute information, to update the generation of the verified data, and stores the updated verified data in the storage unit.

6. The map system of claim 1, wherein the processing module further generates popularity information of each of the POIs according to the number of the respective original data, and presents the filtered POIs with different presentations corresponding to differences between the popularity information in the electronic map via the interface module and the display device.

7. The map system of claim 1, wherein the operation interface comprises an input column and a time scroller for a user to input the search query and the condition of time period, respectively, wherein the time scroller is operable to indicate a time from which a search time period corresponding to the condition of time period is reversed back, and the processing module further updates the displayed filtered POIs in the electronic map via the interface module and the display device when the time scroller is operated to modify the condition of time period.

8. A method for presenting Point of Interest (POI) information in an electronic map, executed by a processor, comprising:

providing an operation interface for receiving a search query and a condition of time period;

retrieving, from a storage unit, a plurality of POIs data, verified data of the POIs each corresponding to a respective one of a plurality of time periods, and standard attribute information of each of the POIs;

collecting original data of the POIs corresponding to the time periods from a plurality of sources, wherein the respective original data has an attribute-counted number which exceeds a threshold value, and the attribute-counted number is an amount for the attribute information of the respective original data, which is the same as the standard attribute information of the respective original data;

analyzing the original data of each of the POIs corresponding to each of the time periods to generate attribute information for the original data of each of the POIs corresponding to each of the time periods;

comparing the generated attribute information with the standard attribute information to determine a number of respective original data whose attribute information matches with the standard attribute information of the respective POI;

generating the verified data according to the number of the respective original data;

filtering the POIs and the verified data according to the search query and the condition of time period to generate the electronic map; and

displaying the electronic map to present the filtered POIs via a display device.

9. The method of claim 8, further comprising:

performing a semantics analysis for at least one of contents, tags, titles, notations, abstracts, and descriptions of the original data to generate the attribute information.

10. The method of claim 8, wherein, when the sources comprise social networks and web albums and the original data comprises photographs, checkin information, and geographic information, the step of analyzing the original data for the generation of the attribute information further comprises analyzing tags, titles, and descriptions of the photographs, the checkin information, and the geographic information.

11. The method of claim 8, further comprising one of the following steps for generating the verified data:

using the number of the respective original data as the verified data, and determining the POIs with the verified data which is greater than zero as the filtered POIs;

setting the verified data of a respective POI to indicate that the respective POI has been successfully verified when the number of the respective original data of each of the POIs exceeds another threshold value, and setting the verified data of a respective POI to indicate that the respective POI has not been successfully verified when the number of the respective original data of each of the POIs is less than the another threshold value; and
