4. Determine data mining goals 4.1 Determine data mining goals A business goal states objectives in business terminology, a data mining goal states project objective in technical terms. For example, the business goal might be "Increase catalogue sales to existing customers" while a data mining goal might be "Predict how many widgets a customer will buy, given their purchases over the past three years, relevant demographic information and the price of the item." Describe the intended outputs of the project that enable the achievement of the business objectives. Note that these are normally technical outputs. Activities: Translate the business questions to data mining goals (e.g., a marketing campaign requires segmentation of customers in order to decide whom to approach in this campaign; the level/size of the segments should be specified). Specify data mining problem type (e.g., classification, description, prediction and clustering).
