Information in this document applies to any platform.


Currently use ctxsys.drvodm.feature_prep to extract features to build svm models like this:

CREATE TABLE model_src.km_pvy4_labeled_DATA_TERMS AS
select sequence_id, attribute_id, value
 FROM TABLE(ctxsys.drvodm.feature_prep (

This extracts features for all documents in the index. It takes too long to extract everything since the index is huge.

If more docs are indexed, Is there a way to just extract features for new docs and not all documents in the index?
