"Text mining, also referred to as text data mining, roughly equivalent to text analytics, refers to the process of deriving high-quality information from text.

In this intoductory chapter we begin with the essence of data mining and a dis-cussion of how data mining is treated by the various disciplines that contribute to this field. We cover "Bonferroni's Principle," which is really a warning about overusing the ability to mine data. This chapter is also the place where we summarize a few useful ...

Call the coefficient vector for this model ß 1. Use the subset selection options in XLMiner to choose a model using only the training data. Call the coefficient vector for this model ß 2. Use the Validation Data to compute the mean and the standard deviation of errors for Model1 by copying ß 1 into cells B5 through K5.

Classification: Definition. - Each record contains a set of attributes, one of the attributes is the class. Find a model for class attribute as a function of the values of other attributes. Goal: previously unseen records should be assigned a class as accurately as possible. - A test set is used to determine the accuracy of the model.

Data Mining is: The efficient discovery of previously unknown, valid, potentially useful, understandable patterns in large datasets. The analysis of (often large) observational data sets to find unsuspected relationships and to summarize the data in novel ways that are both understandable and useful to the data owner.

Classification: predicts categorical class labels (discrete or nominal) classifies data (constructs a model) based on the training set and the values (class labels) in a classifying attribute and uses it in classifying new data. Prediction: models continuous-valued functions, i.e., predicts unknown or missing values.
