World Wide Web (WWW) is a vast resource of hyperlinked and heterogeneous information including text, image, audio, video, and metadata. It is estimated that WWW has expanded by about 2000% since its evolution and is doubling in size every six to ten months. With the rapid growth of information sources available on the WWW and growing needs of users, it is becoming difficult to manage the information on the web and satisfy the user needs. Actually, the authors are drowning in data but starving for knowledge. Therefore, it has become increasingly necessary for users to use some information retrieval techniques to find, extract, filter and order the desired information.
