1. A system for summarizing a concept for a summarization size, the system comprising: a receiving module to receive a query corresponding to the concept; a concept collecting module to collect a plurality of images along with descriptive information corresponding thereto, the plurality of images being collected from a source corresponding to the query; a processing module comprising: an image processing module configured to convert the plurality of images into corresponding feature vectors, and a text processing module configured to process the descriptive information corresponding to each image of the plurality of images; a topic distribution module configured to identify one or more topics for the plurality of images based on the processed descriptive information, and assign one or more topic distribution values corresponding to the one or more topics to each image of the plurality of images; a summarizing module to define a sparse kernel classifier to determine a sparse set of images from the plurality of images to summarize the concept, the sparse set of images being determined based on the feature vectors and the assigned topic distribution values; and an output module to provide the sparse set of images responsive to the query.
