Smart Scoring And Filtering of User-Annotated Geocoded Datasets

摘要

A geographic information system and method that facilitate the display of user-annotated datasets. The dataset can include data such as user-generated videos, photos, blogs, etc., and is processed to search for geo-annotations. The geo-annotations and other data signals are utilized by a scorer to determine a level-of-detail for the particular data. The level-of-detail provided by the scorer is utilized by the geographic information system to determine which data to display as a user navigates around a map.

1. A method of modifying a map, comprising:
searching, using a processor, a data element for user generated text that includes one or more apparent textual geo-annotations associated with the data element and input by a user indicating a location of interest;
searching, by the processor, the data element for geocode information specifying a geographic location of the data element;determining, by the processor, a location proximity of (i) a geographic location for each of the one or more apparent geo-annotations to (ii) the geographic location of the geocode information of the data element; calculating, using the processor, a level-of-detail score for the data element based on the apparent geo-annotations in the user generated text and the location proximity of (i) the geographic location for each of the one or more apparent geo-annotations to (ii) the geographic location of the geocode information of the data element, wherein the level-of-detail score is a score corresponding to a geographic level of detail associated with the data element; determining that the score exceeds a threshold level-of-detail score,
and in response, modifying the map to include a reference to the data element, wherein the reference is placed on a the map at a location corresponding to the data element; and storing the modified map including the reference to the data element in a memory device for subsequent presentation.
