Text-to-text Multi-view Learning For Passage Re-ranking

Jia-Huei Ju, Jheng-Hong Yang, Chuan-Ju Wang · Proceedings of the 44th International ACM SIGIR Conference on Research and Development in Information Retrieval · 2021

Recently, much progress in natural language processing has been driven by deep contextualized representations pretrained on large corpora. Typically, the fine-tuning on these pretrained models for a specific downstream task is based on single-view learning, which is however inadequate as a sentence can be interpreted differently from different perspectives. Therefore, in this work, we propose a text-to-text multi-view learning framework by incorporating an additional view – the text generation view – into a typical single-view passage ranking model. Empirically, the proposed approach is of help to the ranking performance compared to its single-view counterpart. Ablation studies are also reported in the paper.
