Hi, I am little confused with providing the entities in .txt in lookup file. What should be the format of the .txt file [‘Rakesh’, ‘Micheal’,‘Stan’,‘Rita’] Rakesh Micheal Stan Rita I have tried three approches none of them are succesfull in extracting entities rather than example entity provided in nlu.md file. If I ma doing anything wrong please specify.

hey rakesh can you add some more examples i mean 2-3 matching entites related to names

try adding more examples from your .txt file to your nlu data. Sometimes it needs more examples to pick that table. I used ner_spacy for this purpose, it tends to serve me well.

@Akshit Any idea the least number of examples I should add? And also, How do I use ner_spacy? I mean where and how do I have to use it?

Sorry for late reply. I don’t know an exact amount as it depends on how much examples you have in table. I had a table of 50-60 names and I added 8-9 examples in my nlu data and it worked fine. For ner_spacy, you add it in your pipeline and It works very well with certain entities but I personally like duckling because of it’s date filter.

Thanks @Akshit . One more question, can we use both regex and lookup for the same entity ?

Do any one know how to attach .txt file with lookup in rasa 2.0

Hi sorry to interrupt the thread. I am having issues with providing lookup tables in .txt format. I tried the code as advised by @ChikkaUdayaSai but I get this error. [image] Any help will be greatly appreciated. Thanks!

this leads to exception in data/nlu.yml:3: Key 'lookup' was not defined. Path: '/nlu/0' in data/nlu.yml:3: Key 'files' was not defined. Path: '/nlu/0'

Hi @Jason73 , and @susajsnair . You no longer need to point to the file in nlu.yml, instead you can include the files in the same folder that your nlu.yml file is in (default is data), and rasa will search the subdirectories in data recursively.

@fkoerner can you provide a small example! if so it will be helpful. Thanks

We can represent lookup tables like this in Rasa 2.0.

 - lookup: location
   files: |
     - location.txt
