Configuring classification settings

Classification settings give you control over how the text is categorized, depending on the selected level of classification granularity. The Classification settings section is available only when the Classification analysis is enabled on the Select Analysis tab.

1. Open an instance of the Text Analyzer rule and click the Advanced tab.
2. In the Classification settings section, select the granularity level for the analyzed text:
   • Select Sentence Level for high-precision analysis. When you select this option, the system analyzes the text at the level of sentence. Use this classification when you analyze large units of text (for example, emails, blog entries, and so on).
   • Select Document Level to categorize the text as a whole, with no further breakdown. Use this classification when you analyze smaller units of text (for example, Facebook posts or tweets).
3. Select the criteria for categorizing text:
   • Select Select top N categories to display only the specific number of categories that received the highest confidence score.
   • Select Select categories above confidence score threshold to limit the number of displayed categories only to those above a specific confidence score threshold.

   This setting is available only when you select Use model based classification if available in the Classification section of the Select Analysis tab.

   For the Sentence level granularity, depending on the criteria that you selected, the system always displays only the top category or categories only above a 0.5 confidence score.

4. Click Save.
