Query: TAT-QA: A Question Answering Benchmark on a Hybrid of Tabular and
  Textual Content in Finance   Hybrid data combining both tabular and textual content (e.g., financial
reports) are quite pervasive in the real world. However, Question Answering
(QA) over such hybrid data is largely neglected in existing research. In this
work, we extract samples from real financial reports to build a new large-scale
QA dataset containing both Tabular And Textual data, named TAT-QA, where
numerical reasoning is usually required to infer the answer, such as addition,
subtraction, multiplication, division, counting, comparison/sorting, and the
compositions. We further propose a novel QA model termed TAGOP, which is
capable of reasoning over both tables and text. It adopts sequence tagging to
extract relevant cells from the table along with relevant spans from the text
to infer their semantics, and then applies symbolic reasoning over them with a
set of aggregation operators to arrive at the final answer. TAGOPachieves 58.0%
inF1, which is an 11.1% absolute increase over the previous best baseline
model, according to our experiments on TAT-QA. But this result still lags far
behind performance of expert human, i.e.90.8% in F1. It is demonstrated that
our TAT-QA is very challenging and can serve as a benchmark for training and
testing powerful QA models that address hybrid form data.
