Quickstart: Orchestration workflow

Άρθρο
11/21/2024

Use this article to get started with Orchestration workflow projects using Language Studio and the REST API. Follow these steps to try out an example.

Prerequisites

Azure subscription - Create one for free.
A conversational language understanding project.

Go to the Language Studio and sign in with your Azure account.

In the Choose a language resource window that appears, find your Azure subscription, and choose your Language resource. If you don't have a resource, you can create a new one.

Instance detail	Required value
Azure subscription	Your Azure subscription.
Azure resource group	Your Azure resource group.
Azure resource name	Your Azure resource name.
Location	A valid location for your Azure resource. For example, "West US 2".
Pricing tier	A supported pricing tier for your Azure resource. You can use the Free (F0) tier to try the service.

Create an orchestration workflow project

Once you have a Language resource created, create an orchestration workflow project. A project is a work area for building your custom ML models based on your data. Your project can only be accessed by you and others who have access to the Language resource being used.

For this quickstart, complete the conversational language understanding quickstart to create a conversational language understanding project that will be used later.

In Language Studio, find the section labeled Understand questions and conversational language and select Orchestration Workflow.
This will bring you to the Orchestration workflow project page. Select Create new project. To create a project, you will need to provide the following details:

Value	Description
Name	A name for your project.
Description	Optional project description.
Utterances primary language	The primary language of your project. Your training data should primarily be in this language.

Once you're done, select Next and review the details. Select create project to complete the process. You should now see the Build Schema screen in your project.

Build schema

After you complete the conversational language understanding quickstart and create an orchestration project, the next step is to add intents.

To connect to the previously created conversational language understanding project:

In the build schema page in your orchestration project, select Add, to add an intent.
In the window that appears, give your intent a name.
Select Yes, I want to connect it to an existing project.
From the connected services dropdown, select Conversational Language Understanding.
From the project name dropdown, select your conversational language understanding project.
Select Add intent to create your intent.

Train your model

To train a model, you need to start a training job. The output of a successful training job is your trained model.

To start training your model from within the Language Studio:

Select Training jobs from the left side menu.
Select Start a training job from the top menu.
Select Train a new model and type in the model name in the text box. You can also overwrite an existing model by selecting this option and choosing the model you want to overwrite from the dropdown menu. Overwriting a trained model is irreversible, but it won't affect your deployed models until you deploy the new model.

If you have enabled your project to manually split your data when tagging your utterances, you will see two data splitting options:
- Automatically splitting the testing set from training data: Your tagged utterances will be randomly split between the training and testing sets, according to the percentages you choose. The default percentage split is 80% for training and 20% for testing. To change these values, choose which set you want to change and type in the new value.
Note

If you choose the Automatically splitting the testing set from training data option, only the utterances in your training set will be split according to the percentages provided.
- Use a manual split of training and testing data: Assign each utterance to either the training or testing set during the tagging step of the project.
Note

Use a manual split of training and testing data option will only be enabled if you add utterances to the testing set in the tag data page. Otherwise, it will be disabled.
Select the Train button.

Note

Only successfully completed training jobs will generate models.
Training can take some time between a couple of minutes and couple of hours based on the size of your tagged data.
You can only have one training job running at a time. You cannot start other training job wihtin the same project until the running job is completed.

Deploy your model

Generally after training a model you would review its evaluation details. In this quickstart, you will just deploy your model, and make it available for you to try in Language Studio, or you can call the prediction API.

To deploy your model from within the Language Studio:

Select Deploying a model from the left side menu.
Select Add deployment to start a new deployment job.
Select Create new deployment to create a new deployment and assign a trained model from the dropdown below. You can also Overwrite an existing deployment by selecting this option and select the trained model you want to assign to it from the dropdown below.

Note

Overwriting an existing deployment doesn't require changes to your prediction API call, but the results you get will be based on the newly assigned model.
If you're connecting one or more LUIS applications or conversational language understanding projects, you have to specify the deployment name.
- No configurations are required for custom question answering or unlinked intents.
- LUIS projects must be published to the slot configured during the Orchestration deployment, and custom question answering KBs must also be published to their Production slots.
Select Deploy to submit your deployment job
After deployment is successful, an expiration date will appear next to it. Deployment expiration is when your deployed model will be unavailable to be used for prediction, which typically happens twelve months after a training configuration expires.

Test model

After your model is deployed, you can start using it to make predictions through Prediction API. For this quickstart, you will use the Language Studio to submit an utterance, get predictions and visualize the results.

To test your model from Language Studio

Select Testing deployments from the left side menu.
Select the model you want to test. You can only test models that are assigned to deployments.
From deployment name dropdown, select your deployment name.
In the text box, enter an utterance to test.
From the top menu, select Run the test.
After you run the test, you should see the response of the model in the result. You can view the results in entities cards view, or view it in JSON format.

Clean up resources

When you don't need your project anymore, you can delete your project using Language Studio. Select Projects from the left navigation menu, select the project you want to delete, and then select Delete from the top menu.
