ParsTwiNER dataset created by Aghajani et al. [Paper](https://paperswithcode.com/paper/parstwiner-a-corpus-for-named-entity) |
|
|
|
> As a result of unstructured sentences and some misspellings and errors, finding named entities in a noisy environment such as social media takes much more effort. |
|
> ParsTwiNER contains about 250k tokens, based on standard instructions like MUC-6 or CoNLL 2003, gathered from Persian Twitter. Using Cohen’s Kappa coefficient, the consistency of annotators is 0.95, a high score. |
|
> In this study, we demonstrate that some state-of-the-art models degrade on these corpora, and trained a new model using parallel transfer learning based on the BERT architecture. |
|
> Experimental results show that the model works well in informal Persian as well as in formal Persian. |
