A Pretraining Numerical Reasoning Model for Ordinal Constrained Question Answering on Knowledge Base
EMNLP 2021finding
Knowledge Base Question Answering (KBQA) is to answer natural language questions posed over knowledge bases (KBs). This paper targets at empowering the IR-based KBQA models with the ability of numerical reasoning for answering ordinal constrained questions. A major challenge is the lack of explicit…
