LoL

This repository contains the code and trained models for our SIGIR paper LoL: A Comparative Regularization Loss over Query Reformulation Losses for Pseudo-Relevance Feedback .

Usage

Setup

Our experiments are conducted in the following environment with 4 V100 (32 GB) GPUs, where one GPU is dedicated to retrieval and the rest for reformulating queries. At least two GPUs are needed to get it running.

conda create -n cr python=3.8
conda activate cr
conda install -c conda-forge openjdk=11 maven tensorboard jupyterlab ipywidgets
conda install pytorch=1.11 torchvision torchaudio cudatoolkit=10.2 faiss-cpu -c pytorch
conda install -c huggingface -c conda-forge tokenizers=0.12.1 datasets=2.1.0 transformers=4.19.2
# If libs from huggingface don't work, try to install with pip
# pip install tokenizers==0.12.1 datasets==2.1.0 transformers==4.19.2
pip install scipy pyserini pytrec_eval

The corpus, datasets, document matrices, first-pass retrieval results, and model checkpoints can be downloaded from my OneDrive. After downloading, please merge them into this project. Of these, the largest files are those matrices in data/msmarco-passage/matrix/. If you don't want to download them, you need to generate them by running notebooks/prepocess_index_*.ipynb. Simply put, those two notebooks convert the prebuilt-index loaded from pyserini into a specified number of document vectors, which will be used during training or inference.
