Interface OraTextTransform

All Superinterfaces:

OraTransformation

public interface OraTextTransform

extends OraTransformation

Text transform is used to convert the text columns to the nested table columns that can be used for data mining. Nested table will have the extracted words/terms as attribute names. For example, let us say CUSTOMER table has "COMMENTS" column of type CLOB. COMMENTS column could have all the comments made by the customer. It is a useful information that can be used for data mining, but CLOB is not a supported data type for the model build. So a text transform need to be performed to convert the CLOB column as a nested column that will have the extracted words from the comments.

Method Summary

void	setCaseId(java.lang.String caseId) Set the case id column for the input dataset
void	setFeatureTables(java.lang.String[] featureTables) Set the list of text columns and associated feature tables.
void	setTextColumnList(java.lang.String[] textColumnNames) Set the list of text columns that need to be converted to nested columns.
