Identifying particular images from a collection
A method of identifying one or more particular images from an image collection, includes indexing the image collection to provide image descriptors for each image in the image collection such that each image is described by one or more of the image descriptors; receiving a query from a user specifying at least one keyword for an image search; and using the keyword(s) to search a second collection of tagged images to identify co-occurrence keywords. The method further includes using the identified co-occurrence keywords to provide an expanded list of keywords; using the expanded list of keywords to search the image descriptors to identify a set of candidate images satisfying the keywords; grouping the set of candidate images according to at least one of the image descriptors, and selecting one or more representative images from each grouping; and displaying the representative images to the user.
1. A method of identifying one or more particular media objects from a collection, comprising using a data processing system for:
(a) indexing the collection to provide descriptors for each media object in the collection such that each media object is described by one or more of the descriptors;
(b) receiving a query from a user specifying at least one keyword for a media object search, wherein the at least one keyword is not an image descriptor;
(c) using the keyword(s) to search a second collection of tagged media objects to identify co-occurrence keywords;
(d) using the identified co-occurrence keywords to provide an expanded list of keywords;
(e) using the expanded list of keywords to search the descriptors to identify a set of candidate media objects satisfying the keywords;
(f) grouping the set of candidate media objects according to at least one of the descriptors, and selecting one or more representative media objects from each grouping; and
(g) displaying the representative media objects to the user.
2. The method of claim 1 wherein the media object comprises a music or audio file.
