Annotating data for text relation extraction.
In addition to creating a dataset from a JSON file, you can use the annotation platform to annotate your data.
This example demonstrates how to use the annotation platform. In the project that you just created, create an annotation task.
Enter a name for the dataset and upload the raw data file to be annotated. After the upload is complete, click Next. On the settings page for entity and relation names, click Add Entity and Add Relation. Then, enter the names of the entities and relations to extract, as follows:
Entity configuration
Relation configuration
Click the Add Entity and Add Relation buttons until all required entities and relations are displayed. Then, click Submit. After the uploaded dataset is parsed, you can begin annotating. Follow the on-screen instructions to annotate the data.

Annotation guidelines
Annotate all entities and entity relations that appear in the document.
If an entity is already annotated in one document, does it need to be annotated again in another document? Yes, it does.
An annotated entity cannot contain a line feed character ("\n") or a period ("."). If an entity contains one of these characters, the platform cannot detect the entity. However, this does not affect the training process.
