Excluding concepts from extraction
When reviewing your results, you may occasionally find concepts that you did not want extracted or used by any automated category building techniques. In some cases, these concepts have a very high frequency count and are completely insignificant to your analysis. In this case, you can mark a concept to be excluded from the final extraction. Typically, the concepts you add to this list are fill-in words or phrases used in the text for continuity but that do not add anything important and may clutter the extraction results. By adding concepts to the exclude dictionary, you can make sure that they are never extracted.
By excluding concepts, all variations of the excluded concept disappear from your extraction results the next time that you extract. If this concept already appears as a descriptor in a category, it will remain in the category with a zero count after re-extraction.
When you exclude, these changes are recorded in an exclude dictionary in the Resource Editor. If you want to view all of the exclude definitions and edit them directly, you may prefer to work directly in the Resource Editor. See the topic Exclude dictionaries for more information.
To exclude concepts
- In either the Extraction Results pane , Data pane, Category Definitions dialog box, or Cluster Definitions dialog box, select the concept(s) that you want to exclude from the extraction.
- Right-click to open the context menu.
- Select Exclude from Extraction. The concept is added to the exclude dictionary in the Resource Editor and the Extraction Results pane background color changes, indicating that you need to re-extract to see your changes. If you have several changes, make them before you re-extract.
