Custom API

Supported Labeling Types: Span Labeling, Row Labeling, Bounding Box Labeling

We also support Custom API in case you want to use your own model for ML-assisted labeling by simply providing the API URL. Ensure your custom API follows the required request structure to integrate smoothly with the Datasaur platform. Here’s how to set it up:

Setting Up Your Custom API for ML-Assisted Labeling

1. Create an API: Build an API for your model that adheres to a specific request and response format compatible with the Datasaur App. For guidance, refer to the API Creation Example.

2. Request and Response Structure: You can find example request and response body near the API URL input field or in the examples below.

3. Entering Your API URL: Once your API is ready, fill in the API URL in the designated field under the extension.

4. For Span Based project

   1. Sentences per request (0 = all): Determine how many text you want to include in 1 request to your API service.

5. For Row Based project

   1. Target Text: Choose the text input that your model will use as a reference.

   2. Target Question: Select the output column your model will predict.

   3. Faster Prediction Speed: Optionally, toggle this feature to run predictions faster via the backend.

6. Confidence Score: Adjust the value according to your needs.

7. Apply Labels: After setting up, click "Predict Labels" to automatically apply labels to your document based on your model's predictions.
