Hi Mudassir,

To get it to work for other cities as well, you could introduce either RegexEntityExtractor (Components) or RegexFeaturizer (Components) in your config.yml. Also, in your training data, you should add a lookup table (NLU Training Data) so that the model is able to pick up other cities without having them explicitly in your intent examples.

Hope this helps, let me know if you have other inquiries.

Regards, Nikola

What is your configuration? Do you have an entity extraction method and did you define them in your domain file correctly?

If you have list cities then do add a lookup table listing all the cities and think you need to add the RegexEntityExtractor. Otherwise I think you could also use spacy. You can read more here: Using Custom spaCy components | The Rasa Blog | Rasa
