AraT5: Text-to-Text Transformers for Arabic Language Generation


This is the repository accompanying our paper AraT5: Text-to-Text Transformers for Arabic Language Understanding and Generation. In this is the repository we Introduce AraT5MSA, AraT5Tweet, and AraT5: three powerful Arabic-specific text-to-text Transformer based models;

A new version of AraT5 comes out and we recommend using the AraT5v2-base-1024 instead of this version.

How to use AraT5 models

Below is an example for fine-tuning AraT5-base for News Title Generation on the Aranews dataset

!python run_trainier_seq2seq_huggingface.py \
        --learning_rate 5e-5 \
        --max_target_length 128 --max_source_length 128 \
        --per_device_train_batch_size 8 --per_device_eval_batch_size 8 \
        --model_name_or_path "UBC-NLP/AraT5-base" \
        --output_dir "/content/AraT5_FT_title_generation" --overwrite_output_dir \
        --num_train_epochs 3 \
        --train_file "/content/ARGEn_title_genration_sample_train.tsv" \
        --validation_file "/content/ARGEn_title_genration_sample_valid.tsv" \
        --task "title_generation" --text_column "document" --summary_column "title" \
        --load_best_model_at_end --metric_for_best_model "eval_bleu" --greater_is_better True --evaluation_strategy epoch --logging_strategy epoch --predict_with_generate\
        --do_train --do_eval

In addition, we release the fine-tuned checkpoint of the News Title Generation (NGT) which is described in the paper. The model available at Huggingface (UBC-NLP/AraT5-base-title-generation).

    abstract = "Transfer learning with a unified Transformer framework (T5) that converts all language problems into a text-to-text format was recently proposed as a simple and effective transfer learning approach. Although a multilingual version of the T5 model (mT5) was also introduced, it is not clear how well it can fare on non-English tasks involving diverse data. To investigate this question, we apply mT5 on a language with a wide variety of dialects{--}Arabic. For evaluation, we introduce a novel benchmark for ARabic language GENeration (ARGEN), covering seven important tasks. For model comparison, we pre-train three powerful Arabic T5-style models and evaluate them on ARGEN. Although pre-trained with {\textasciitilde}49 less data, our new models perform significantly better than mT5 on all ARGEN tasks (in 52 out of 59 test sets) and set several new SOTAs. Our models also establish new SOTA on the recently-proposed, large Arabic language understanding evaluation benchmark ARLUE (Abdul-Mageed et al., 2021). Our new models are publicly available. We also link to ARGEN datasets through our repository: https://github.com/UBC-NLP/araT5.",
