# Spoken-Arabic Named-Entity Dataset (Levantine NER v1.0)

A curated corpus of Levantine-Arabic sentences annotated for Named Entities, plus parallel dual-annotator files for assessing annotation noise.  
Ideal for fine-tuning Arabic-BERT–style models on noisy, spoken data and testing cross-register robustness.
