RANKING IMAGES FOR WEB IMAGE RETRIEVAL
A system, method, and computer-readable media are disclosed for providing images in a ranked order. The system can include an aggregation component for aggregating a plurality of images with corresponding text. Additionally, the system can include a name detector a name detector for detecting names within a search query. Moreover, the system can include a ranking component for ranking the aggregated images based on whether the name detector detects a name.
1 . A method for providing images in a ranked order, comprising:
identifying at least one image on a web page of a website;
identifying at least one item of text associated with the at least one image on the web page;
associating the at least one image and the at least one item of text within a database; and
ranking the at least one image based on one or more ranking factors within the database, wherein at least one of the one or more ranking factors considers a link relationship between the at least one image and at least one other image.
2 . The method according to claim 1 , wherein the one or more ranking factors include a ranking factor that considers a number of websites that include an identical copy of the at least one image.
3 . The method according to claim 1 , wherein the one or more ranking factors include a ranking factor that considers a number of websites that include a similar version of the at least one image.
4 . The method according to claim 1 , wherein the one or more ranking factors include a ranking factor that considers an image size of the at least one image.
5 . The method according to claim 1 , wherein the one or more ranking factors include a ranking factor that considers the total number of links there are to the URL of the at least one image.
6 . The method according to claim 1 , wherein a first set of metadata associated with the at least one image is shared by each image having the link relationship.
7 . The method according to claim 1 , wherein the one or more ranking factors include a ranking factor that considers the frequency that the at least one image appears on the website.
8 . A system for providing images in a ranked order, comprising:
an aggregation component for aggregating a plurality of images with corresponding text;
a name detector for detecting names within a search query;
a ranking component for ranking the aggregated images based on whether the name detector detects a name.
9 . The system according to claim 8 , further comprising a face detector.
10 . The system according to claim 9 , wherein images within the aggregated images that are detected by the face detector to include at least one face of a person are ranked higher when the name detector detects a name of a person within the search query.
11 . The system according to claim 9 , wherein images within the aggregated images that are detected by the face detector to include at least one face of a person are ranked lower or higher when the name detector does not detect a name of a person within the search query.
12 . The system according to claim 8 , wherein the ranking component further ranks the aggregated images based on at least one image feature.
13 . The system according to claim 12 , wherein the at least one image feature includes at least one of a number of pixels, an aspect ratio, an image file size, image entropy, and image gradient.
14 . One or more computer-readable media having computer-usable instructions stored thereon for performing a method of providing images in a ranked order, the method comprising:
receiving a search query including at least one item of text;
identifying at least one image related to the search query;
ranking the at least one images using one or more ranking factors, wherein at least one of the one or more ranking factors considers a distance the at least one item of text is to the at least one image on a web page; and
providing the ranked one or more images.
15 . The computer-readable media according to claim 14 , further comprising converting the distance for each item of text within the search query to a preliminary score using a sigmoid function.
16 . The computer-readable media according to claim 15 , wherein the preliminary score for each item of text is summed in order to calculate an overall score.
17 . The computer-readable media according to claim 14 , wherein the distance is determined by considering one or more of a number of intervening words, symbols, and tags between the at least one item of text and the at least one image.
18 . The computer-readable media according to claim 14 , wherein the one or more ranking factors includes a ranking factor that considers whether the at least one image includes a face of a person.
19 . The computer-readable media according to claim 14 , wherein the one or more ranking factors includes a ranking factor that considers whether the search query includes a name of a person.
20 . The computer-readable media according to claim 14 , wherein the one or more ranking factors includes a ranking factor that considers the total number of images on the web page.
