The advent of media-sharing sites has drastically increased the volume of multimedia resources on the web, yet these collections become more difficult for searching and navigating result from their magnitude. This paper present a novel search system called ContextSeer to improve search quality:

1. To develop wc-tf-idf, by improving the concept tf-idf with more emphasis on the higher-ranked object, since the context cues of lower-ranked objects should be less important than those of higher- ranked ones.
2. To propose a efficient canonical image selection algorithm cannoG, which generates multiple representative views related to the query.
   
3. To form a new benchmark Flickr550, which contains 0.5 million public photos from Flickr through Flickr API, for evaluating ContextSeer.
