To quickly check or uncheck those concepts that will be used for scoring, click the toolbar button for Include Concepts..

Figure 1. Include Concepts toolbar button

Clicking this toolbar button will open the Include Concepts dialog box to allow you to select concepts based on rules. All concepts that have a check mark on the Model tab will be included for scoring. Apply a rule in this subdialog to change which concepts will be used for scoring.

You can choose from the following options:

Check concepts based on highest frequency. Top number of concepts. Starting with the concept with the highest global frequency, this is the number of concepts that will be checked. Here, frequency refers to the number of times a concept (and all its underlying terms) appears in the entire set of the documents/records. This number could be higher than the record count, since a concept can appear multiple times in a record.

Check concepts based on document count. Minimum count. This is the lowest document count needed for the concepts to be checked. Here, document count refers to number of documents/records in which the concept (and all its underlying terms) appears.

Check concepts assigned to the type. Select a type from the drop-down list to check all concepts that are assigned to this type. Concepts are assigned to types automatically during the extraction process. A type is a semantic grouping of concepts. Types include such things as higher-level concepts, positive and negative words and qualifiers, contextual qualifiers, first names, places, organizations, and more. See the topic Type dictionaries for more information.

Uncheck concepts that occur in too many records. Percentage of records. Unchecks concepts with a record count percentage higher than the number you specified. This option is useful for excluding concepts that occur frequently in your text or in every record but have no significance in your analysis.

Uncheck concepts assigned to the type. Unchecks concepts matching the type that you select from the drop-down list.
