Association Analysis: Basic Concepts and Algorithms

This chapter presents a methodology known as association analysis which is useful for discovering interesting relationships hidden in large data sets The uncovered relationships can be represented in the form of associa-Table 6 1 An example of market basket transactions TID Items 1 {Bread Milk} 2 {Bread Diapers Beer Eggs}

What is a measure of interestingness in association analysis?
In the business world, time is money, so only the most interesting data patterns will be targeted. In association analysis (considered a subset of data mining), we call these rules Measures of Interestingness.
How many patterns can an association analysis algorithm generate?
Association analysis algorithms have the potential to generate a large number of patterns. For example, although the data set shown in Table 6.1 contains only six items, it can produce up to hundreds of association rules at certain support and confidence thresholds.
What is association analysis?
Such valuable information can be used to support a vari-ety of business-related applications such as marketing promotions, inventory management, and customer relationship management. This chapter presents a methodology known as association analysis, which is useful for discovering interesting relationships hidden in large data sets.
What is the purpose of a chapter in association analysis?
The first part of the chapter is devoted to explaining the basic concepts of association analysis and the algorithms used to efficiently mine such pat-terns. The second part of the chapter deals with the issue of evaluating the discovered patterns in order to prevent the generation of spurious results.
