- Title: An Online Question Answering System based on Sub-graph Searching
- Authors: Shuangyong Song
- Abstract summary: We design a sub-graph searching mechanism to solve this problem by creating sub-graph index, and each answer generation step is restricted in the sub-graph level.
We use this mechanism into a real online QA chat system, and it can bring obvious improvement on question coverage by well answer-ing entity based questions.

- Abstract: Knowledge graphs (KGs) have been widely used for question answering (QA)
applications, especially the entity based QA. However, searching an-swers from
an entire large-scale knowledge graph is very time-consuming and it is hard to
meet the speed need of real online QA systems. In this pa-per, we design a
sub-graph searching mechanism to solve this problem by creating sub-graph
index, and each answer generation step is restricted in the sub-graph level. We
use this mechanism into a real online QA chat system, and it can bring obvious
improvement on question coverage by well answer-ing entity based questions, and
it can be with a very high speed, which en-sures the user experience of online
QA.

We introduce REALTIME QA, a dynamic question answering (QA) platform that announces questions and evaluates systems on a regular basis.
We build strong baseline models upon large pretrained language models, including GPT-3 and T5.
GPT-3 tends to return outdated answers when retrieved documents do not provide sufficient information to find an answer.

We address the problem of how the Question Answering (QA) quality of a given system can be improved.
Our main contribution is an approach capable of identifying wrong answers provided by a QA system.
In particular, our approach has shown its potential while removing in many cases the majority of incorrect answers.

Our model shows SOTA performance of SQ generation on the NQ dataset (20.1 BLEU-4).
We further apply our model on out-of-domain news articles, evaluating with a QA system due to the lack of gold questions and demonstrate that our model produces better SQs for news articles -- with further confirmation via a human evaluation.
