# CategoryFindRelevantSentences

Return the most relevant sentences in a document, a file, or a piece of text, based on training about which documents are relevant and which are irrelevant.

In most cases, you train two categories (one with relevant data and one with irrelevant data), and build the categories by using the CategoryBuild action with the Relevance parameter. If you create only one Relevance category, `CategoryFindRelevantSentences` returns all sentences. If you create more than two categories, you must use the RelevantCat parameter for the CategorySetDetails action to mark one of the categories as the relevant category, and all other categories are treated as irrelevant. The `CategoryFindRelevantSentences` action requires one of the child categories to be set as the RelevantCat.

Like Simple categories, you create groups of Relevance categories by creating them under different parent categories. When you send the `CategoryFindRelevantSentences` action, you must specify the parent ID to determine which set of Relevance categories to use.

You can specify secure documents for this action. Use the SecurityInfo parameter to specify the security string to use.

NOTE: This is an administrative action that can be sent only by users that belong to an authorization role that allows the `Admin` standard role, or which enables the action explicitly. See Authorization Roles Configuration Parameters.
