Welcome to the Text Transformation Wizard

Oracle Data Mining lets you build models using the Support Vector Machine and Non-Negative Matrix Factorization algorithms where the input table has one text column. Before you can use a table containing a text column in a mining operation, you must transform the text column into a nested table consisting of items of type DM_Nested_Numericals or DM_Nested_Categoricals. This wizard transforms the text columns for you. The wizard also extracts features from the text column. The text column in a sequence of data mining operations, such as the tables used to build, test, and apply the same model, must be transformed in the same way.

Since the ODM Java interface requires that text be stored in a table but not in a view, the output of this wizard is a table.

For an overview of ODM support for text mining, see Text Mining.
