Hi everyone, this is my very first post.
Here is my problem:
I have some lookup tables (e.g. countries + others) and I need to pass the valued slots to a remote Action Server.
Everything is working fine but since my extracted values will be used by a case-sensitive query builder I need to ‘normalize’ them.
I know I can set the case_sensitive flag on RegexEntityExtractor, BUT I need to extract the items in the very same way they’re defined in the lists (they’re pre-defined, I can’t modify them)
I try to explain better.
I have a lookup table like this one (showing only a few examples for simplicity)
version: “2.0”
nlu:
- lookup: product
examples: |- laptops
- DVDS
- Lamps
Consider these sentences:
How many laptops did we sell? → it will extract ‘laptops’ 
How many dvds did we sell? → it will extract ‘dvds’ 
Once extracted I call the remote endpoint which will execute a query, hence I have to pass ‘DVDS’ not ‘dvds’ (the ‘where’ condition will work only with ‘DVDS’)
I can’t add a custom component / an intermediate Custom Action and I cannot modify the remote API, all I can do is configure Rasa
If you have any idea about a zero-code solution please let me know,
otherwise please tell me if I can send a PR (I already modified RegexFeaturizer and RegexEntityExtractor to show a possible solution but it must be in Rasa Open Source, not in a fork lol)
Thanks!
Leo
