Classification of support tickets by machine learning is a well-known use case, but in the course of working with customers on this problem, we have come across a frequent problem where customers do not yet have (good) enough data for training a customized model that can classify according to their business categories.
One of the ways to overcome this entry barrier is to use pre-trained Natural Language Processing (NLP) models that detect the ticket language or sentiment to help in ticket triage.
In the 2003 update of Service Ticket Intelligence, we added support for language and sentiment detection for the Classification API. As these are pre-trained models, there is no need for training, and using it is as simple as specifying this in the Services Object during the inference call.

Yes, it was - what we made possible now is the ability to get the detected language even without any models trained (or activated).
Here are the environment variables in postman:
Notice below that there is no need to enter a value for model_id if you are using the pre-trained services.
Next, step through the postman collection with the following:
Here's the response from List active models, showing that there are currently no active models in my account.
Request to classify a single message with services options
"field" is a required property generally used to describe the input field to classify in a custom model. In this case, it does not matter what the value is in the "field" property.
Sample Response
Yes, you can - you would need to add "detect_category" to the services object. In this request below, I have already activated one of the models which I trained earlier with both category & priority.

Hang on - wasn't language detection always in the classification API?
Yes, it was - what we made possible now is the ability to get the detected language even without any models trained (or activated).
Here are the environment variables in postman:
- Access the Service Ticket Intelligence sample postman collection
- Follow the steps here to create your Service Ticket Intelligence service keys
Notice below that there is no need to enter a value for model_id if you are using the pre-trained services.
Next, step through the postman collection with the following:
- Get Access Token
- List active models
- Classify single message (with services options) > sample code below
Here's the response from List active models, showing that there are currently no active models in my account.

}Great! So can I also add these services to my custom trained model?
Yes, you can - you would need to add "detect_category" to the services object. In this request below, I have already activated one of the models which I trained earlier with both category & priority.
