Service interactions handled through chatbots is a top priority for many telecom operators because of their benefits like better customer experience, human replacement for routine tasks, cost reduction, etc. As per a Forrester finding, the use of virtual agents has jumped from 28% in 2012 to 58% in 2015. This indicates the increase in scope of deploying them for enhanced self-service levels. Apart from the basic technology elements, it is knowledge management that drives a chatbot to the best of its purpose. Having an updated database of knowledge is crucial since answers to customer queries majorly rely on the same. Also, to facilitate human-like conversations, knowledge has to be customized for user understanding.
