Challenges for Data-driven Dialogue Systems: Finding the Goldilocks Zone for Conversational Data

Oliver Lemon

I will review current approaches to data-driven dialogue systems, both for tasks and social chat, focusing on three main issues: synthetic data, big data, and noisy data. With reference to some of our current projects, I will illustrate (1) the limitations of using synthetic data; (2) how linguistic knowledge, in the form of a semantic grammar, can be used in combination with machine learning to bootstrap dialogue systems from very small amounts of data; and (3) how our Amazon Alexa Challenge system has been built to avoid some of the problems of large amounts of real but problematically noisy data.
