[FEATURE REQUEST] Functionality for analyzing the differences between two Annotation objects. #67
Description
Activity
Currently pull request #68 begins preliminary work mentioned above.
Ideas for further improvements:
- Method in
Datasetthat will allow to compare gold and predicted over a whole corpus by utilizing the diff functionality implemented in Added Annotations.diff(); unit tests #68 . - Give the diff method optional
fuzzyparameters that will highlight model predictions that are almost correct (maybe off by a few characters)
- Method in
I believe the functionality you described is covered by Annotations.compare_by_index(), which has the strict parameter for fuzzy predictions.
What problem does your feature solve?
A method to do analysis of annotations (namely for the application of looking at differences between gold and predicted annotations).
Describe the solution you'd like
The Annotation class should be given some static methods like
Annotation.diff(ann_object_1, ann_object_2)will output the difference between to annotation objects. Maybe some parameter for leniency to deal with fuzzy annotation matching.Interface sklearn to compute various evaluation metrics between two annotation files (assuming one is gold and one is predicted).
Additional context
This would be very useful for result analysis and guiding the building of pipelines.
