Natural language processing and machine learning enable IBM Watson to derive insights from various types of digital communication. With its text analysis services, users can understand the sentiment and concepts of content, get personality characteristics of individuals based on textual information, develop human-like conversations with virtual agents, etc.

Detecting tone of customer messages—whether they are text or audio—is also among the many possible scenarios of employing Watson. For a hands-on session on a Bluemix day at the IBM Finland office, we prepared a microservice-based app that analyzes text and provides emotion scores for customer feedback. This post shares the details on how this app was implemented using several Bluemix services and reveals some lessons learned.
