What is bert-base-arabertv02?
bert-base-arabertv02 is an advanced Arabic language model based on Google's BERT architecture, specifically designed for Arabic language understanding. It represents a significant improvement over previous versions, trained on a massive dataset of 77GB of Arabic text including Wikipedia dumps, news articles, and the OSCAR corpus. This version does not use pre-segmentation, making it more flexible for various Arabic NLP tasks.
Implementation Details
The model was trained using TPUv3-8 hardware, processing 420M examples with sequence length 128 and 207M examples with sequence length 512. It implements improved preprocessing techniques, particularly around handling punctuation and numbers, and uses a refined wordpiece vocabulary system.
- Trained for 3M total steps with varying batch sizes
- Implements better pre-processing with space insertion between numbers and characters
- Uses BertWordpieceTokenizer for improved tokenization
- Supports Fast tokenizer implementation from the transformers library
Core Capabilities
- Sentiment Analysis across multiple datasets (HARD, ASTD-Balanced, ArsenTD-Lev, LABR)
- Named Entity Recognition with ANERcorp
- Arabic Question Answering on Arabic-SQuAD and ARCD
- General Arabic language understanding tasks
