rwse-checker

Real-word spelling errors (RWSEs) pose special challenges for detection methods, as they ‘hide’ in the form of another existing word and in many cases even fit in syntactically. rwse-checker is a modern Transformer-based implementation of earlier probabilistic methods based on confusion sets. It detects RWSEs with a good balance between missing errors and raising too many false alarms. The confusion sets are dynamically configurable, allowing teachers to easily adjust which errors trigger feedback.

Example Usage

from rwse import RWSE_Checker 

checker = RWSE_Checker()
checker.set_confusion_sets([['their','there'],['to','too','two']])

print(checker.check("there", "I want to buy [MASK] cars."))
print(checker.check("too", "I want [MASK] buy their cars."))

which yields

('their', 0.003510827198624611)
('to', 0.9989504218101501)
