ABSTRACT
Growing image collections have created a need for effec-

they often are not sufficient by themselves. Many databases,
such as those at Flickr are augmented by keywords supplied
by its users. A big stumbling block however lies in the fact
that many keywords are actually similar or occur in common
combinations which is not captured by the linear metadata
system employed in the databases. This paper proposes a

feature vectors for each image. The taxonomy tree could
be used to enhance the user search experience in several
