第一步:安装rank_bm25库 rank_bm25是一个Python库,用于实现BM25算法。在开始使用之前,我们需要先安装这个库。可以使用pip命令进行安装,命令如下: pip install rank_bm25 在执行这个命令之后,我们就可以开始使用rank_bm25库了。 第二步:准备数据集 在使用rank_bm25算法之前,我们需要准备一个数据集,其中包含
pip install rank_bm25 If you want to be sure you're getting the newest version, you can install it directly from github with pip install git+ssh://git@github.com/dorianbrown/rank_bm25.git Usage For this example we'll be using the BM25Okapi algorithm, but the others are used in pre...
首先,你需要确认 rank_bm25 模块是否已经在你的Python环境中安装。你可以尝试在Python解释器或交互式环境中导入该模块来检查: python import rank_bm25 如果导入成功,说明模块已安装;如果导入失败并抛出 ModuleNotFoundError,则需要继续以下步骤。 通过pip安装rank_bm25模块: 如果模块未安装,你可以使用 pip 命令来安...
Once theconda-forgechannel has been enabled,rank-bm25can be installed withconda: conda install rank-bm25 or withmamba: mamba install rank-bm25 It is possible to list all of the versions ofrank-bm25available on your platform withconda:

为了完整性,我们还展示了 Elastic Rerank 在各个数据集上的结果。这代表了整个套件中平均 39% 的提升。截至撰写本文时,BM25 经重排序后在MTEB 排行榜上大约位列第 20 名。所有更有效的模型都使用了大嵌入,至少有 1024 维,并且模型显著更大(平均比 Elastic Rerank 大 30 倍)。
