Claim 0:
1. A method for identifying correlation between property listings, the method comprising:
identifying, within a geographic area of a predetermined size, a source property listing and a target property listing;
storing, in a first database, at least one image corresponding to the source property listing;
storing, in a second database, at least one image corresponding to the target property listing;
for each image corresponding to the source property listing and each image corresponding to the target property listing, identifying a group of keypoints in the image, each keypoint corresponding to a keypoint descriptor;
for each image corresponding to the source property listing, determining an image category for the image;
for each image corresponding to the source property listing,
(i) comparing the keypoint descriptors of the group of keypoints in the image to the respective keypoint descriptors of the group of keypoints in each of the at least one images corresponding to the target property listing;
(ii) determining, based on the comparing, a number of shared keypoints between the image corresponding to the source property listing and each respective image corresponding to the target property listing;
(iii) determining, for each image corresponding to the target property listing, based on the determination of the number of shared keypoints, whether to pair the image corresponding to the source property listing with the image corresponding to the target property listing;
determining a likelihood of correlation between the source property listing and the target property listing based on one or more of: (1) a number of shared keypoints between a first image corresponding to the source property listing and a second image corresponding to the target property listing, (2) whether the first image is paired with one or more images corresponding to the target property listing, and (3) the image category for the first image; and
removing, from the first database, at least one image corresponding to the source property listing having an image category of view.
