Create intents and add utterances

When it comes to designing and implementing a Microsoft Azure AI solution, creating intents and adding utterances play a crucial role in building an effective conversational experience. Intents define the goals or tasks the user wants to accomplish, while utterances represent examples of user input that are associated with specific intents. In this article, we will explore the importance of intents and utterances and learn how to create them in Azure AI.

Understanding Intents and Utterances

Intents and utterances form the building blocks of conversational AI. Intents represent the users’ intentions, and they help the AI system understand what the user wants to achieve. For example, in a customer support chatbot, intents could be “Get Support,” “Place an Order,” or “Check Order Status.”

Utterances, on the other hand, are the actual user inputs associated with specific intents. These inputs can be in the form of text or speech. For instance, an utterance for the intent “Get Support” could be “I need help with my account.” By associating utterances with intents, the AI system can learn to recognize patterns and respond accordingly.

Creating Intents in Azure AI

In Azure AI, intents are created using the Language Understanding (LUIS) service. LUIS is a powerful cloud-based service that enables developers to build language understanding into their applications. To create intents in Azure AI, follow these steps:

1. Create a new LUIS resource in the Azure portal.
2. Define the intents that align with the tasks or goals you want your AI solution to support. For example, you might create intents like “Book Flight,” “Cancel Reservation,” or “Get Weather.”
3. Train the LUIS model by providing a set of example utterances for each intent. Ensure that the examples cover a wide range of variations that users might input.
4. Optionally, you can annotate the example utterances with entities to extract specific information. Entities represent important pieces of information within an utterance, such as dates, locations, or product names.
5. After training, test the LUIS model using sample inputs to verify its performance. Iterate and refine the model as needed.

Adding Utterances to Intents

Once you have defined the intents in LUIS, the next step is to add utterances to each intent. Utterances provide real-world examples of how users might interact with your AI solution. To add utterances, follow these steps:

1. Navigate to the LUIS portal and select your LUIS model.
2. Open the “Intents” section and select the intent you want to add utterances to.
3. Click on the “Add utterance” button and provide a sample user input in the text box.
4. Repeat this process for multiple utterances, ensuring that you cover various ways users might express the same intent.
5. As you add utterances, LUIS will automatically suggest the intent for each input based on your predefined intents. Review and confirm the suggested intent for each utterance.

Train, Test, and Refine

After adding utterances, it’s essential to train and test your LUIS model to improve its accuracy and effectiveness. Training helps the model learn from the provided data, while testing validates its performance. To train and test your LUIS model, follow these steps:

1. Click on the “Train” button in the LUIS portal to initiate the training process.
2. Once training is complete, test the model using sample inputs. Evaluate whether the model accurately predicts the correct intents for the given utterances.
3. Analyze the test results and make necessary refinements to improve the model’s accuracy. This can involve adding more utterances, providing alternative phrasing, or adjusting the intent classification thresholds.

Conclusion

In the world of conversational AI, creating intents and adding utterances are pivotal in building an effective Microsoft Azure AI solution. With Azure’s Language Understanding service, developers can define intents, associate utterances, and train models to understand user inputs accurately. By carefully crafting intents and providing diverse utterances, you can create an AI solution that delivers an exceptional conversational experience to users. So, start exploring intents and utterances in Azure AI and unleash the power of conversational AI in your applications.
