Configuring text extraction analysis

Configure text extraction analysis by specifying tags, keywords, entity extraction models, and pattern extraction rules. Use tags and keywords to mark specific terms and their synonyms that you want to identify in the analyzed text. Text and pattern extraction models help to identify various types of named entities.

Text extraction analysis helps you track the activity of your customers and competitors or discover the products and features that customers comment on most often.

1. In the Records panel, click Decision > Text Analyzer.
2. Open the Text Analyzer rule that you want to edit.
3. Perform any of the following actions:
   • To detect the most relevant words or phrases in a document to, for example, create word clouds, or perform a faceted search, in the Text extraction section, select the Enable auto-tag extraction check box and perform one of the following actions:
     • To detect all significant tags in the document, select the Detect all tags radio button.
     • To detect a specific number of tags in the document, select the Detect top N tag(s) radio button and specify the number of tags that you want to detect, starting from the most significant one.
   • To extract keywords, named entities of specific types, or entities whose names follow various patterns, in the Text extraction section, select the Enable text extraction check box.
4. If you enabled the Text extraction setting, configure one of the following text extraction options:
