A chatbot must be able to understand different variations of text to respond to users in a better way. This is where the “synonym” feature can help. It allows you to configure synonyms from Bot Builder.
When you configure synonyms from Bot Builder, you basically design a chatbot design that can understand user queries in a better way and then match with the corresponding knowledge base.
If the customer uses jargon in his query, the system will understand all the synonyms of it and can use it to match with the corresponding knowledge base.
