An Interactive Adversarial Reward Learning-Based Spoken Language Understanding System

Yu Wang, Yilin Shen, Hongxia Jin


Most of the existing spoken language understanding systems can perform only semantic frame parsing based on a single-round user query. They cannot take users’ feedback to update/add/remove slot values through multiround interactions with users. In this paper, we introduce a novel interactive adversarial reward learning-based spoken language understanding system that can leverage the multiround users’ feedback to update slot values. We perform two experiments on the benchmark ATIS dataset and demonstrate that the new system can improve parsing performance by at least 2.5% in terms of F1, with only one round of feedback. The improvement becomes even larger when the number of feedback rounds increases. Furthermore, we also compare the new system with state-of-the-art dialogue state tracking systems and demonstrate that the new interactive system can perform better on multiround spoken language understanding tasks in terms of slot- and sentence-level accuracy.
