KBQA is a task that requires to answer questions by using semantic structured
information in knowledge base. Previous work in this area has been restricted
due to the lack of large semantic parsing dataset and the exponential growth of
searching space with the increasing hops of relation paths. In this paper, we
propose an efficient pipeline method equipped with a pre-trained language
model. By adopting Beam Search algorithm, the searching space will not be
restricted in subgraph of 3 hops. …
