AZFAKENEWS: A BENCHMARK DATASET FOR FAKE NEWS DETECTION IN THE AZERBAIJANI LANGUAGE
Disinformation on digital platforms is a very important problem for public trust and political debate. Even so, most research on automated fake news detection has stayed on a small number of high-resource languages. This paper presents AzFakeNews, the first large-scale benchmark dataset for fake news detection in Azerbaijani. Azerbaijani is a low-resource Turkic language with more than 30 million speakers. We built the dataset from two sources: scraping of news articles from five major Azerbaijani media websites, and generation of synthetic fake articles via Meta's LLaMA language model. The final dataset has 3,782 articles (3,000 authentic and 782 synthetic) across 34 topic categories. For the baseline we fine-tuned the Azerbaijani aLLMA model on this corpus. It reached 91.03% accuracy and 91.11% macro-F1 on the test split, because of which we consider it a strong baseline compared to mBERT, XLM-RoBERTa and the base LLaMA on the same data. We hope the dataset helps close a gap in Azerbaijani NLP and supports cross-language research on disinformation.
