WojoodRelations: Arabic Relation Extraction Corpus and Modeling

Relation extraction (RE) is a core task in natural language processing, crucial for semantic understanding, knowledge graph construction, and enhancing downstream applications. Existing work on Arabic RE remains limited due to the language's rich morphology and syntactic complexity, and the lack of large, highquality datasets. In this paper, we present Wojood Relations , the largest and most diverse Arabic RE corpus to date, containing over 33K sentences (∼ 550K tokens) annotated with ∼ 15K relation triples across 40 relation types. The corpus is built on top of Wojood NER dataset with manual relation annotations carried out by expert annotators, achieving a Cohen's κ of 0.92, indicating high reliability. In addition, we propose two methods: NLI-RE, which formulates RE as a binary natural language inference problem using relation-aware templates, and GPT-Joint, a few-shot LLM framework for joint entity and RE via relationaware retrieval. Finally, we benchmark the dataset using both supervised models and incontext learning with LLMs. Supervised models achieve 92.89% F1 for RE, while LLMs obtain 72.73% F1 for joint entity and RE. These results establish strong baselines, highlight key challenges, and provide a foundation for advancing Arabic RE research.
