βοΈ Auto labeling documents with prebuilt models or one of your own models
In custom extraction model labeling page, you can now auto label your documents using one of Document Intelligent Service prebuilt models or models you previously trained.
For some documents, there can be duplicate labels after running auto label. Make sure to modify the labels so that there are no duplicate labels in the labeling page afterwards.
βοΈ Auto labeling tables
In custom extraction model labeling page, you can now auto label the tables in the document without having to label the tables manually.
βοΈ Add test files directly to your training dataset
Once you train a custom extraction model, make use of the test page to improve your model quality by uploading test documents to training dataset if needed.
If a low confidence score is returned for some labels, make sure your labels are correct. If not, add them to the training dataset and relabel to improve the model quality.
βοΈ Make use of the document list options and filters in custom projects
Use the custom extraction model labeling page. You can now navigate through your training documents with ease by making use of the search, filter, and sort by feature.
