bert-web-bg
New upgraded and cased version of the model available here: bert-web-bg-cased There was a reported bug in this model with the Bulgarian letter "й" which is solved in the new version of the model.
This model is pretrained from scratch BERT on Bulgarian dataset created at the Bulgarian Academy of Sciences under the ClaDa-BG Project . It achieves the following results on the evaluation set:
- Loss: 1.4510
- Accuracy: 0.6906

Uses
The model is trained on the masked language modeling objective and can be used to fill the mask in a textual input. It can be further finetuned for specific NLP tasks in the online media domain such as Event Extraction, Relation Extracation, Named Entity Recognition, etc. This model is intended for use from researchers and practitioners in the NLP field.

Bias, Risks, and Limitations
We examine whether the model inherits gender and racial stereotypes. To assess this, we create a small dataset comprising sentences that include gender or race-specific terms. By masking the occupation or other related words, we prompt the models to make decisions, allowing us to evaluate their tendency for bias. Some examples are given below:

bert_web_bg = pipeline('fill-mask', model='usmiva/bert-web-bg')
