Before we begin, you must first create a knowledge base. You can create a new knowledge base following these steps:
- Sign in to the QnA Maker portal (qnamaker.ai) with your Azure credentials.
- Click on “Create a knowledge base” from the top navigation bar.
- Fill in the details appropriately while proceeding across the steps. You can choose your QnA service, name your Knowledgebase, and choose languages.
- You can either populate your Knowledge Base with URLs and files or prefer to skip that step if you’re planning to add everything manually.
- Click “Create your KB”.
Adding Question-Answer Pairs
Once your knowledge base is created, we can embark on manually adding the Question-Answer pairs.
Enter the appropriate Question and the corresponding Answer in the respective text fields. You can follow the step-by-step instructions below:
- From your knowledge base, head towards the ‘Edit’ tab.
- In the ‘Add QnA pair’ section below your knowledge base content, click ‘+ Add QnA pair’.
- You can add your own custom question in the ‘Question’ field and its appropriate response under the ‘Answer’ field.
- After you’ve filled in both, click “Save and train” to save and submit the changes made.
You can continue this process to add as many Question-Answer pairs as you require.
Here’s an example of how a typical QnA pair would look like,
| Question | Answer |
|---|---|
| What are Azure cognitive services? | Azure Cognitive Services are APIs, SDKs, and services available to help developers build intelligent applications without having direct AI or data science skills or knowledge. |
QnA Pair Variations
Remember, for a question, there can be multiple versions representing the same intent. To add alternate phrasing for a question:
- Click ‘+ Add alternate phrasing’.
- Enter your alternate phrasing for the question.
- Click “Save and train” to save and submit your changes.
Ensure that these variations still correspond to the same answer, as in this example:
| Question | Alternate phrasing | Answer |
|---|---|---|
| What are Azure cognitive services? | Tell me about Azure cognitive services. | Azure Cognitive Services are APIs, SDKs, and services available to help developers build intelligent applications without having direct AI or data science skills or knowledge. |
In conclusion, manually adding Question-Answer pairs is an instrumental process allowing you to train your AI model to respond as perfectly as possible to a query. The ability to add alternate phrasing enhances the adaptiveness of the model. Regularly updating and training your knowledge base with new QnA pairs can dramatically improve the performance and flexibility of your AI solution.
