VIPAS: Virtual Link Powered Authority Search in the Web

This chapter proposes a new algorithm with the idea of using virtual links that are created according to what the user behaves in browsing the output list of the query result. These virtual links are then employed to identify authoritative resources in the Web. Specifically, the algorithm referred to as algorithm “virtual link powered authority search” (VIPAS) is divided into three phases. The first phase performs basic link analysis. The second phase collects statistics by observing the user behavior in browsing pages listed in the query result, and virtual links are then created according to what is observed. In the third phase, these virtual links as well as real ones are taken together to produce an updated list of authoritative pages that will be presented to the user when the query with similar keywords is encountered next time. © 2003 Elsevier Inc.
