Constraint-free Join Processing on Hyperlinked Web Data

Abstract

In this paper, we introduce the concept of web join for combining hyperlinked Web data. A web join is one of the web algebraic operator in our web warehousing system called Whoweda (WareHouse Of WEb DAta). It can be used to gather useful, composite information from two web tables. Web join and outer web join (a derivative of web join) operations can be used to detect and represent changes to hyperlinked Web data. We discuss the syntax, semantics and algorithms of web join and outer web join operators. We also present how to detect and represent changes to hyperlinked Web data using these two operations. © 2002 Springer-Verlag Berlin Heidelberg.
