CAMeLBERT-CA POS-EGY Model

Model description

CAMeLBERT-CA POS-EGY Model is a Egyptian Arabic POS tagging model that was built by fine-tuning the CAMeLBERT-CA model. For the fine-tuning, we used the ARZTB dataset . Our fine-tuning procedure and the hyperparameters we used can be found in our paper " The Interplay of Variant, Size, and Task Type in Arabic Pre-trained Language Models ." Our fine-tuning code can be found here .

Intended uses

You can use the CAMeLBERT-CA POS-EGY model as part of the transformers pipeline. This model will also be available in CAMeL Tools soon.

How to use

To use the model with a transformers pipeline:

>>> from transformers import pipeline
>>> pos = pipeline('token-classification', model='CAMeL-Lab/bert-base-arabic-camelbert-ca-pos-egy')
>>> text = 'عامل ايه ؟'
>>> pos(text)
[{'entity': 'adj', 'score': 0.9990943, 'index': 1, 'word': 'عامل', 'start': 0, 'end': 4}, {'entity': 'pron_interrog', 'score': 0.99863535, 'index': 2, 'word': 'ايه', 'start': 5, 'end': 8}, {'entity': 'punc', 'score': 0.99990875, 'index': 3, 'word': '؟', 'start': 9, 'end': 10}]

Note : to download our models, you would need transformers>=3.5.0 . Otherwise, you could download the models manually.

    abstract = "In this paper, we explore the effects of language variants, data sizes, and fine-tuning task types in Arabic pre-trained language models. To do so, we build three pre-trained language models across three variants of Arabic: Modern Standard Arabic (MSA), dialectal Arabic, and classical Arabic, in addition to a fourth language model which is pre-trained on a mix of the three. We also examine the importance of pre-training data size by building additional models that are pre-trained on a scaled-down set of the MSA variant. We compare our different models to each other, as well as to eight publicly available models by fine-tuning them on five NLP tasks spanning 12 datasets. Our results suggest that the variant proximity of pre-training data to fine-tuning data is more important than the pre-training data size. We exploit this insight in defining an optimized system selection model for the studied tasks.",
