Text Mining in Oracle Data Mining

A source table for Data Mining may include one or more columns of text. A text column cannot be used as a target. The case table itself must be a relational table; it cannot be created as a view.

Text must undergo a transformation process described in Data Preparation for Text before it can be mined. Once the data has been properly transformed, the case table can be used for building, testing, or scoring data mining models. The following Oracle Data Mining algorithms support text:


Note:

These algorithms do not support text:
  • O-Cluster

  • Decision Tree when you connect to an Oracle Database 11g

  • Association (Apriori)

Any text attributes are automatically filtered out for model builds when you use O-Cluster or Decision Tree connected to an Oracle Database 11g.
