Integrating Rasa with a knowledge base to encode domain knowledge and resolve entities

tutorial-knowledge-base's Issues

graql command not recognized + excepetion error 'action_query_entities'

After I train, rasa actions server, and rasa shell I get this error after a few lines of dialogue, I say hello, bot replies "I can give you some info......", I ask

"Can you give me information on my account please"

I get;

Encountered an exception while running action 'action_query_entities'. Bot will continue, but the actions events are lost. Make sure to fix the exception in your custom code

When first building the bot;

When I get to this command:

graql console --keyspace banking --file knowledge_base/schema.gql

I get no command found, but I can change the graql to grakn and it works?

I've installed grakn, run the server no problem, when I run; python knowledge_base/migrate.py

I get some errors, listed below

Copy of the question from the forum

https://forum.rasa.com/t/are-there-any-existing-working-examples-of-rasa-2-grakn-out-there/40408

Are there any existing working examples of Rasa 2 + Grakn out there? Ideally - with Rasa Knowledge Actions (if they are stable enough).
I saw an old demo https://github.com/RasaHQ/tutorial-knowledge-base 1

The thing is that it will be perfect not to battle with migration to Rasa 2, new features of Knowledge Actions, and a fresh version of Grakn at the same time :slight_smile:

@tabergma maybe you know of some new projects in this area that can be scaffolded? Chat knowledge bases are a really interesting topic, especially with the rich structure of Grakn that got things like Workbase and GraMi

I saw several requests for update - so I hope it’s interesting not only for me. Will be happy to help where I can.
Thanks!

Updating to typeDB

could you please update this tutorial to typeDB ?
Precisely how is get_concepts() replaceable in typeDB ?

Update to latest Rasa & grakn versions

Hello,

Has anyone been able to run this with current Rasa 1.10.2 and grakn 1.8 versions?

Hi @tabergma

I am having an issue with 'entity-type-mapping' too.
When I run rasa shell it gives me this error.

Glad if could you help me with this error.
I am using python 3.7
rasa 1.1.4
grakn 1.5.7

And i did not do any changes in actions.py or graph_database.py or any other file in the repository.

Update lookuptables

I see reference to lookup lists are used in the training samples for query_kb intents.
Talking with reference to the banking demo,
does this imply every time an entry is made to the kb like a person / bank, it needs to be added in this list and model has to be retrained?

Can you please update the tutorial to the lates versions of rasa and grakn.

@tabergma Can you Please update the repository to the latest versions of the grakn and rasa, Or add a file to do all the necessary modifications in the current repository to make it run with latest versions.

why do we have two schema files?

can someone explain why did we need another schema file (schema.gql, schema.py)?
and why does schema.py which has representation and keys, not have all attributes of an entity?
does that imply something or am i getting it wrong?

Using for multi-language

Can we us this knowledge-based feature for multiple language?

Cannot create Grakn Table

Hello @tabergma !

I just read your post about using the Knowledge Base for expanding Rasa's functionality, trust me its one of the Most Awesome integration idea I have ever read with Rasa!. The post was a wonderful article that certainly intrigued my attention towards using a Knowledge Base in my personal project.

However I was thrilled to learn and use Grakn for my pet project, I stumbled upon the below error:

Also, I checked the other issue posted by someone here; regarding almost the same thing and tried your suggestion of ensuring that Grakn is running OR not. However, my Grakn server is up and running at least what I make out of these lines:
