Viewing significant concepts

Concepts are basic units of linguistic or quantitative information that are derived from the textual content of content items. Classification Workbench identifies concepts that are statistically significant to a content item's relationship to a specified category. You can view significant concepts to understand how IBM® Content Classification analyzes and classifies content items.

About this task

Positive concepts are indicative of an item's inclusion in a specified category; negative concepts are indicative of an item's exclusion from a specified category. They are highlighted and color-coded on the Significant concepts window.

Positive concepts are highlighted in light blue.
Negative concepts are highlighted in maroon.

Restriction: Significant concepts are available only for knowledge base projects. The project must contain a relevant knowledge base, for example, a knowledge base that was created by using the Create knowledge base feature. In addition, your project must contain valid analysis data.
