Anserini supports RM3, Axiomatic Semantic Matching, and BM25prf: https://github.com/castorini/anserini/tree/master/src/main/java/io/anserini/rerank/lib However, only RM3 is exposed in Pyserini: https://github.com/castorini/pyserini/blob/master/pyserini/search/__main__.py#L72 We usually do not find much of a difference between different techniques. |
