1. A method of identifying one or more particular images from an image collection, comprising using a data processing system for:

  • (a) 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 image descriptor, with or without user input;

    (b) receiving a query from a user specifying at least one keyword for an image search, wherein the at least one keyword is not an image descriptor;

    (c) using the keyword(s) to search a second collection of tagged images or a lexical database to identify keywords that are co-occurrent with the user-provided keyword(s);

    (d) using identified co-occurrence keywords to provide an expanded list of keywords;

    (e) using the expanded list of keywords to search the image descriptors to identify a set of candidate images satisfying the keywords;

    (f) 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

    (g) displaying the representative images to the user.
