Cost-Benefit Analysis of Bags in a Web Warehouse
Conference Proceeding Article
Sets and bags are closely related structures and have been studied in relational databases. A bag is different from a set in that it is sensitive to the number of times an element occurs while a set is not. In this paper, we introduce the concept of web bag in the context of a web warehouse called WHOWEDA (Warehouse Of Weda Data) which we are currently building. Informally, a web bag is a web table which allows multiple occurrences of identical web tuples.Web bag helps to discover useful knowledge from a web table such as visible documents (or web sites), luminous docu-ments and luminous paths. In this paper, we provide a cost-benefit analysis of materializing web bags as compared to web tables with distinct web tuples.
