Use Cases

  • Tagging emails: Text classification functionality is applied on incoming emails to identify customer satisfaction through email tagging. A text model is created with three topics, Satisfied, Neutral, and Not Satisfied with related words. The appearance of related words in email subject and body identifies the topics, and tags the email to it. These email tags can be used to analyze customer satisfaction. 
  • Request classification and task assignment: Text classification activity picks topics from the received requests, classifies the text and feeds the result to an assign activity that assigns these requests to relevant teams for processing.
