Concept Model: Model Tab

In concept models, the Model tab displays the set of concepts that were extracted. The concepts are presented in a table format with one row for each concept. The objective on this tab is to select which of the concepts will be used for scoring.

Note: If you generated a category model nugget instead, this tab will present different information. See the topic Category Model Nugget: Model Tab for more information.

All concepts are selected for scoring by default, as shown in the check boxes in the leftmost column. A checked box means that the concept will be used for scoring. An unchecked box means that the concept will be excluded from scoring. You can check multiple rows by selecting them and clicking one of the check boxes in your selection.

To learn more about each concept, you can look at the additional information provided in each of the following columns:

Concept. This is the lead word or phrase that was extracted. In some cases, this concept represents the concept name as well as some other underlying terms associated with this concept. To see which underlying terms are part of a concept, display the Underlying Terms pane inside this tab and select the concept to see the corresponding terms at the bottom of the dialog box. See the topic Underlying Terms in Concept Models for more information.

Global. Here, global (frequency) refers to the number of times a concept (and all its underlying terms) appears in the entire set of the documents/records.

• Bar chart. The global frequency of this concept in the text data presented as a bar chart. The bar takes the color of the type to which the concept is assigned in order to visually distinguish the types.
• %. The global frequency of this concept in the text data presented as a percentage.
• N. The actual number of occurrences of this concept in the text data.

Docs. Here, Docs refers to the document count, meaning number of documents or records in which the concept (and all its underlying terms) appears.

• Bar chart. The document count for this concept presented as a bar chart. The bar takes the color of the type to which the concept is assigned in order to visually distinguish the types.
• %. The document count for this concept presented as a percentage.
• N. The actual number of documents or records containing this concept.

Type. The type to which the concept is assigned. For each concept, the Global and Docs columns appear in a color to denote the type to which this concept is assigned. A type is a semantic groupings of concepts. See the topic Type dictionaries for more information.

Working with Concepts

By right-clicking a cell in the table, you can display a context menu in which you can:

• Copy. The selected concept(s) are copied to the clipboard.
• Copy With Fields The selected concept(s) are copied to the clipboard along with the column heading.
• Check Selected. Checks all check boxes for the selected rows in the table thereby including those concepts for scoring.
• Uncheck Selected. Unchecks all check boxes for the selected rows in the table.
• Check All. Checks all check boxes in the table. This results in all concepts being used in the final output.
• Uncheck All. Unchecks all check boxes in the table. Unchecking a concept means that it will not be used in the final output.
