- TripleFact: Defending Data Contamination in the Evaluation of LLM-driven Fake News Detection (2025 · 12 citations)
Large language models can see evaluation benchmarks during pre-training. This benchmark data contamination (BDC) can make fake news detection look better than it really is, because models may recall debunked claims instead of reasoning about them. Static datasets such as LIAR assume test items are unseen, and LLMs… - Advancing Arabic Sentiment Analysis: ArSen Benchmark and the Improved Fuzzy Deep Hybrid Network (2024 · 4 citations)
Arabic sentiment analysis has few resources, and the common benchmarks (Gold Standard, SemEval) are old and contain fewer than 10,000 items. - LiveFact: A Dynamic, Time-Aware Benchmark for LLM-Driven Fake News Detection (2026 · 2 citations)
Benchmarks for fake news detection are mostly fixed snapshots. LLMs may have absorbed them during pre-training (benchmark data contamination, BDC), and they usually hand the model all the evidence at once, which does not match how verification works as a story is still unfolding. LiveFact addresses this with a…
