Answering Open-Domain Multi-Answer Questions via a Recall-then-Verify Framework

This repository includes the original implementation of our ACL2022 paper "Answering Open-Domain Multi-Answer Questions via a Recall-then-Verify Framework", which contains the following two branches:

• retriever: code for finetuning a retriever
• rectify: code for training a recall-then-verify system

Due to the limited upload size, zip files have been chunked into smaller ones whose names share the same prefix except the last letter (e.g., data.zipchunkaa and data.zipchunkab are the first and the second chunk of the original zip file data.zip, respectively). Please merge chunks with the same prefix before unzipping them (e.g., cat data.zipchunka* > data.zip && unzip data.zip).
