Given a set of itemsets, the algorithm attempts to find subsets that are common to at least a minimum number of the itemsets. Answer: Apriori algorithm Diff: 2 Page Ref: 229 60) One way to accomplish privacy and protection of individuals' rights when data mining is by ________ of the customer records prior to applying data mining applications, so that the records cannot be traced to an individual. Answer: de-identification Diff: 2 Page Ref: 237 61) List five reasons for the growing popularity of data mining in the business world. Answer: • More intense competition at the global scale driven by customers' ever-changing needs and wants in an increasingly saturated marketplace • General recognition of the untapped value hidden in large data sources • Consolidation and integration of database records, which enables a single view of customers, vendors, transactions, etc. • Consolidation of databases and other data repositories into a single location in the form of a data warehouse • The exponential increase in data processing and storage technologies • Significant reduction in the cost of hardware and software for data storage and processing • Movement toward the demassification (conversion of information resources into nonphysical form) of business practices Diff: 2 Page Ref: 194 62) List 3 common data mining myths and realities. Answer: 1) Myth: Data mining provides instant, crystal-ball-like predictions. Reality: Data mining is a multistep process that requires deliberate, proactive design and use. 2) Myth: Data mining is not yet viable for mainstream business applications. Reality: The current state of the art is ready to go for almost any business type and/or size. 3) Myth: Data mining requires a separate, dedicated database. Reality: Because of the advances in database technology, a dedicated database is not required. 4) Myth: Only those with advanced degrees can do data mining. Reality: Newer Web-based tools enable managers of all educational levels to do data mining. 5) Myth: Data mining is only for large firms that have lots of customer data. Reality: If the data accurately reflect the business or its customers, any company can use data mining. Diff: 2 Page Ref: 239
