STEP 4: Click on the columns tab to verify the columns. Here, we can uncheck the unwanted columns.
Drag the OLE DB source output arrow onto the Term Extraction Transformation to perform a transformation on the source Data.
STEP 5: Double click on the Term Extraction Transformation will open the Editor to configure it. Within the Term Extraction tab, You need to choose the column to use for the Extraction from the available input columns. We left the output column names to the default Term and Score.
Exclusion Tab: If you want to exclude specific terms during term extraction, configure this Tab by specifying a column that contains exclusion terms.
In this example, let us leave this because we want to extract all the Nouns from the source data.
STEP 6: Advanced tab of the Term Extraction Transformation Editor Dialog box is essential to select Term Type, Source Type, and Frequency Threshold. In this example, we are extracting Noun only. So, we chose Noun as the term type and selected the Frequency Threshold as 1.
From the below screenshot, you can see there is a warning symbol on the Term Extraction Transformation. It shows that the error output is not connected. You can remove the warning symbol by configuring the error output of the Term Extraction Transformation. So double-click on the Configure Error Output button opens a new window to set the error output.
The default configuration of a Term Extraction Transformation is to redirect error rows. You can get rid of this warning by connecting the error output. Or by changing the default behavior to Ignore Failure or Fail Component. Let’s change to Ignore Failure
