Abstract
Influence of items on some other items might not be the same as the association between these sets of items. Many tasks of data analysis are based on expressing influence of items on other items. In this chapter, we introduce the notion of an overall influence of a set of items on another set of items. We also discuss an extension to the notion of overall association between two items in a database. Using this notion, we have designed two algorithms of influence analysis involving specific items in a database. As the number of databases increases on a yearly basis, we have adopted incremental approach to these algorithms. Experimental results are reported on both synthetic and real-world databases.
