Arabic-Book-Review-Sentiment-Assessment

This model is a fine-tuned version of google-bert/bert-base-multilingual-uncased on labr dataset. It achieves the following results on the evaluation set:

• Loss: 1.5290

Model description

The purpose of this model is to analyze Arabic review texts and predict the appropriate rating for them, based on the sentiment and content of the review. This can be particularly useful in tasks such as sentiment analysis, customer feedback analysis, or any application where understanding the sentiment conveyed in an Arabic textual review is important.

Intended uses & limitations

While the model performs well with formal Arabic text (Examples 1, 3, and 4), it may struggle with slang or informal language, occasionally assigning higher ratings than expected (Example 2). Additionally, the model is not capable of interpreting verbally given ratings (Example 5). Users should be aware of these limitations and provide context-appropriate input for optimal performance.
