Set-Encoder

This repository contains the code for the paper: Set-Encoder: Permutation-Invariant Inter-Passage Attention for Listwise Passage Re-Ranking with Cross-Encoders.

We use lightning-ir to train and fine-tune models. Download and install the library to use the code in this repository.

Model Zoo

We provide the following pre-trained models:

Model Name	TREC DL 19 (BM25)	TREC DL 20 (BM25)	TREC DL 19 (ColBERTv2)	TREC DL 20 (ColBERTv2)
set-encoder-base	0.724	0.710	0.788	0.777
set-encoder-large	0.727	0.735	0.789	0.790

Inference

We recommend using the lightning-ir cli to run inference. The following command can be used to run inference using the set-encoder-base model on the TREC DL 19 and TREC DL 20 datasets:

lightning-ir re_rank --config configs/re-rank.yaml --config configs/set-encoder-finetuned.yaml --config configs/trec-dl.yaml
