Botium Box includes a paraphraser to quickly generate new user examples based on given ones. After adding a handful of user examples to the utterance list, click on the Paraphrase it! button to get a couple of suggestions for additional user examples and select the ones you want to use.
Before using the Paraphraser, you have to configure the Paraphraser API Key in the Botium Box System Settings.
The result is a big number of additional similar user examples to use for further training.
