RRF_all — Retrieval Only Task

Is this a manual (human intervention) or automatic run?: automatic
Does this run leverage neural networks?: yes
Does this run leverage proprietary models in any step of the retrieval pipeline?: no
Does this run leverage open-weight LLMs (> 5B parameters) in any step of the retrieval pipeline?: no
Does this run leverage smaller open-weight language models in any step of the retrieval pipeline?: yes
Was this run padded with results from a baseline run?: yes
What would you categorize this run as?: Multi-Stage Pipeline pointwise
Please provide a short description of this run: A hybrid retrieval pipeline combining BM25 with query expansion, dense embedding search, and neural rerankers (ColBERTv2, MiniLM). Results are fused via RRF, with the top-100 outputs submitted.
Please give this run a priority for inclusion in manual assessments.: 1 (top)
