Rasa: how can I make use of Duckling in RASA NLU?

[dilipbobby]

Used backend / pipeline (spacy_sklearn.):

Operating system (UBUNTU):

Issue:
I want an example of using duckling in rasa NLU.

Content of configuration file (if used & relevant):

[wrathagom]

I answered this on Gitter, are the docs insufficient?

https://rasa-nlu.readthedocs.io/en/latest/pipeline.html#ner-duckling

In short:

• Install duckling (java version or docker version)
• Add Duckling to your pipeline (ner_duckling or ner_duckling_http respectively to above)
• Train some data
• Parse data and see duckling output

@dilipbobby did that help?

[dilipbobby]

for now I'm clear :) thank you .if I have any problem I will reopen the issue

[anaportela]

will ner_duckling classify any named entity a user specifies, or do I need to add training data with that entity?

[ConstantinPeticila]

Hello!
My current config file is in json format and I install duckling module but I don't know how to add it in the config file.This is the content of file(path and data are not relevant):
{
"project":"nav-os",
"language":"en",
"pipeline":"spacy_sklearn",
"path" :"/home/costi/Documents/arhive/automated-data-training-master",
"data" :"/home/costi/Documents/arhive/rasa_train.json"
}
I don't have acces to your Gitter.Thanks

[akelad]

which version of rasa_nlu are you using? this is a very old config format 😄
you should change your pipeline to contain all the specific components, and then add ner_duckling like specified here: https://nlu.rasa.com/pipeline.html#ner-duckling

Is duckling also supported for german? The wit.ai website does not list german:
https://duckling.wit.ai/

But the python wrapper does:
https://github.com/FraBle/python-duckling/blob/master/duckling/language.py#L8

Now I am wondering if german duckling is supported and the docs are just old. Did you test that?

[akelad]

it does indeed support it

[reza-ebrahimi]

@akelad Is there any way to use wit.ai duckling component in rasa_nlu? or is they are same?

[wrathagom]

It is the same. Keep in mind though that ner_duckling is being phased out and uses a very old version of Wit's Duckling. It's recommended to use ner_duckling_http, which can use the latest version of Duckling.

@wrathagom unlike ner_duckling, ner_duckling_http doesn't work at all. Can you help me, why? Here is my pipeline

pipeline:
- name: "nlp_spacy"
- name: "tokenizer_spacy"
- name: "intent_entity_featurizer_regex"
- name: "intent_featurizer_spacy"
- name: "ner_crf"
- name: "ner_duckling_http"
- name: "ner_synonyms"
- name: "intent_classifier_sklearn"

[akelad]

please ask usage questions on the forum, there's info on how to configure this here: https://rasa.com/docs/nlu/components/#ner-duckling-http

[Shreeti17]

@wrathagom can I user 'ner_duckling_http' and 'ner_cnf' both in the configuration file or 'ner_duckling_http' is enough?

@akelad - the sad part is the urls you have specified seems to be not working now. We keep getting "Oops… this page doesn't exist." error when we navigate.
