A team of scientists from Salesforce Research and Chinese University of Hong Kong have released Photon, a natural language interface to databases (NLIDB). The team used deep-learning to construct a parser that achieves 63% accuracy on a common benchmark and an error-detecting module that prompts users to clarify ambiguous questions.

The team demonstrated Photon at the recent ACL 2020 conference, and team member Victoria Lin described the system in a recent blog post. The core of Photon is a neural-network-based semantic parser which converts natural language questions from a human user into SQL queries; the parser achieves 63.2% exact-match accuracy on the Spider dataset, which is the second highest result achieved to date.
