Extraction change history
If your extraction results are not what you expect, you can review the extraction history of your fields.
Here, you see each of your extraction results. With this information it is possible to make changes to field extraction to improve the extraction results.
For the best results, run extraction benchmarks before you make any changes to your extraction settings. Once your changes are made run a second benchmark and compare the two benchmarks. This enables you to see improvements and problems with your overall extraction results.
