Homophone Error Degradation in Dense Passage Retrieval Systems

Pre-trained Language Models have recently emerged in Information Retrieval as providing the backbone of a new generation of neural systems that outperform traditional methods on a variety of tasks. However, it is still unclear to what extent such approaches generalize in zero-shot conditions. The recent BEIR benchmark provides partial answers to this question by comparing models on datasets and tasks that differ from the training conditions. We aim to address the same question by comparing models under more explicit distribution shifts. To this end, we build three query-based distribution shif

Research goal: To what extent do homophone errors degrade the performance of dense passage retrieval systems relative to single-character typos across diverse domain datasets?
