QARiB: QCRI Arabic and Dialectal BERT

About QARiB

QCRI Arabic and Dialectal BERT (QARiB) model, was trained on a collection of ~ 420 Million tweets and ~ 180 Million sentences of text. For the tweets, the data was collected using twitter API and using language filter. lang:ar. For the text data, it was a combination from Arabic GigaWord, Abulkhair Arabic Corpus and OPUS.

QARiB: Is the Arabic name for "Boat".

Model and Parameters:

  • Data size: 14B tokens
  • Vocabulary: 64k
  • Iterations: 10M
  • Number of Layers: 12

Using QARiB

You can use the raw model for either masked language modeling or next sentence prediction, but it's mostly intended to be fine-tuned on a downstream task. See the model hub to look for fine-tuned versions on a task that interests you. For more details, see Using QARiB

How to use

You can use this model directly with a pipeline for masked language modeling:

>>>from transformers import pipeline
>>>fill_mask = pipeline("fill-mask", model="./models/data60gb_86k")

>>> fill_mask("شو عندكم يا [MASK]")
