Oracle Data Mining has Offered This as Part of ODM since 10g
Amazingly, Teradata just realized that analyzing unstructured data produces large amounts of data, and that analyzing this data is a requirement for customers. It has announced what appears to be beta to test out this functionality.
Oracle has had text mining included with ODM since Oracle 10g. Oracle was on of the first to provide native support XML support in the Oracle database, and Content DB provides industry leading, web services-based capability to securely manage large amounts of unstructured content in a single repository with support for Oracle BPEL for workflow capabilities.
