Open Domain Question Answering Using Web Tables [article]

Kaushik Chakrabarti, Zhimin Chen, Siamak Shakeri, Guihong Cao
2020 arXiv   pre-print
However, many queries answerable using tables are non-factoid in nature. In this paper, we develop an open-domain QA approach using web tables that works for both factoid and non-factoid queries.  ...  Previous works on question answering (QA) using web tables have focused on factoid queries, i.e., those answerable with a short string like person name or a number.  ...  answering using web tables: Our work is most related to previous works on question answering using web tables [16, 21] .  ...
