Watson Workers

Type: NLP Worker

A Watson worker takes user input and sends it to Watson bot for natural language processing. A Watson worker can be created through the CLI, or through portal.

Creating a Watson Assistant

The following contains useful documentation on getting started with a Watson Assistant, which will be needed in the next sections https://cloud.ibm.com/docs/assistant/services-information.html

Assuming you have setup a Watson Assistant, you can find the required information for creating a watson worker within Watson by following these steps:

  • Navigate to the the Watson Assistants dashboard, which looks like this Watson Assistants Dashboard

  • Navigate to the settings of your Watson Assistant by clicking the Settings option here Watson Assistant Settings

  • Click on the API details tab, and take note of the following:

    • Assistant ID
    • Assistant URL
    • API key

The page should look something like this: Watson Assistant Settings

Details for Watson Worker Configuration

Once you have this information, you can derive the details which will be required for creating a watson worker:

  • Secret: The secret is the Watson Assistant API key that will be used to communicate with Watson. This is the API Key mentioned above on the Watson Assistant API Details section. See Creating a Watson Secret for more information on creating the secret.

  • AssistantId: The identifier of the particular assistant you wish to use hosted in the assistant resource, this is available on the Watson Assistant API Details page.

  • ServiceUrl: The Watson service url to use for communicating with Watson. This can be obtained from the Assistant URL you retrieved from the API Details section of your Watson Assistant. The Watson Assistant URL will be in the form https://api.eu-gb.assistant.watson.cloud.ibm.com/instances/some-id/v2/assistants/some-id/sessions. Your ServiceUrl for your worker configuration is just this section of the url https://api.eu-gb.assistant.watson.cloud.ibm.com.

  • AssistantInstance: The identifier of the watson assistant resource, this can be taken from the Assistant URL you retrieved from the API Details section of your Watson assistant. The image highlights the section of the url which contains the instance id.

  • NluConfidenceThresholdOverride [Optional] You can use this as an override of the returned detected intent confidence. If this value is higher than that returned from the nlu provider it will change the response to be a fallback, this value defaults to 0.
