Announcing support for synonyms and slot value validation on Amazon Lex

You can now provide synonyms for slot values in Amazon Lex. With the synonym functionality, you can specify multiple synonyms for a slot value in your chatbot. The synonyms specified are resolved to the corresponding slot values. For example, if the slot value is “comedy”, with “funny” and “humorous” specified as synonyms, then user input of “funny” will now be resolved to “comedy”. You can optimize your business logic to implement code for just the slot value instead of entire set of synonyms. In addition, the chatbot automatically resolves minor variants of the slot value to the original value without the user having to explicitly specify the synonym. For example, if “pineapple” is one of the slot values and the user value is “pineapples” then slot is resolved to the value “pineapple”.
