No Regex Entity Extraction

Getting Started with Rasa

Hello all,

i’m new to rasa and i’m stuck with entities extraction using RegexEntityExtractor. But i have the same Problem with Ducklings too. My Bot is working so far. But the Entity “trackingid” isn’t recognized/filled.

I hope somebody can show me the right way.

Hey @DrEvil75, welcome to the forum :slight_smile:

it looks like your intent examples have spaces in the entity annotations. This prevents any entity extractor in your NLU pipeline (DIETClassifier or RegexEntityExtractor) to learn to extract the entity. Try to remove the spaces, like this:

that is [1234567890] (trackingid) -> that is [1234567890](trackingid)

In my case, everything works when I delete the spaces. Let me know how it goes for you.
