This looks cool but there's not a lot of documentation about how this works or how the bot reads in the training data.

There's the example file here: https://github.com/olivia-ai/olivia/blob/master/res/intents....

But trying every variation of "hi" doesn't return any of the correct responses from the online demo. And Olivia doesn't seem to do text normalization (stripping out punctuation), so saying "Hey." instead of "Hey" or "Hey!" doesn't work.
