Welcome to the Text Transformation Wizard

Oracle Data Mining lets you build classification, regression, anomaly detection, feature extraction, and k-Means clustering models 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 appropriately. The way that the text column is prepared depends on how the data will be used.

This wizard transforms the selected text column into a nested table consisting of items of type DM_Nested_Numericals or DM_Nested_Categoricals. The transformed column can be used in a PL/SQL program that uses the DBMS_DATA_MINING PL/SQL program.

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