Query: How to Build Robust FAQ Chatbot with Controllable Question Generator?   Many unanswerable adversarial questions fool the question-answer (QA) system
with some plausible answers. Building a robust, frequently asked questions
(FAQ) chatbot needs a large amount of diverse adversarial examples. Recent
question generation methods are ineffective at generating many high-quality and
diverse adversarial question-answer pairs from unstructured text. We propose
the diversity controllable semantically valid adversarial attacker (DCSA), a
high-quality, diverse, controllable method to generate standard and adversarial
samples with a semantic graph. The fluent and semantically generated QA pairs
fool our passage retrieval model successfully. After that, we conduct a study
on the robustness and generalization of the QA model with generated QA pairs
among different domains. We find that the generated data set improves the
generalizability of the QA model to the new target domain and the robustness of
the QA model to detect unanswerable adversarial questions.
