# BERTic-Incorrect-Spelling-Annotator

This BERTic model is designed to annotate incorrectly spelled words in text. It utilizes the following labels:

- 0: Word is written correctly,
- 1: Word is written incorrectly.

## Model Output Example

Imagine we have the following Croatian text:

_Model u tekstu prepoznije riječi u kojima se nalazaju pogreške ._

If we convert input data to format acceptable by BERTic model:

_[CLS] model [MASK] u [MASK] tekstu [MASK] prepo ##znije [MASK] riječi [MASK] u [MASK] kojima [MASK] se [MASK] nalaza ##ju [MASK] pogreške [MASK] . [MASK] [SEP]_

The model might return the following predictions (note: predictions chosen for demonstration/explanation, not reproducibility!):

_Model 0 u 0 tekstu 0 prepoznije 1 riječi 0 u 0 kojima 0 se 0 nalazaju 1 pogreške 0 . 0_

We can observe that in the input sentence, the word `prepoznije` and `nalazaju` are spelled incorrectly, so the model marks them with the token (1).

## More details

Testing model with **generated** test sets provides following result:

Precision: 0.9954
Recall: 0.8764
F1 Score: 0.9321
F0.5 Score: 0.9691

Testing the model with test sets constructed using the **Croatian corpus of non-professional written language by typical speakers and speakers with language disorders RAPUT 1.0** dataset provides the following results:

Precision: 0.8213  
Recall: 0.3921  
F1 Score: 0.5308  
F0.5 Score: 0.6738
