Companies want to offer chat bots to their customers and employees to answer questions, enable self-service, and showcase their products and services. Implementing and maintaining chat bots by hand costs time and is expensive. Companies typically have web APIs for their services, which are often documented with an API specification. This paper presents a compiler that takes a Swagger API specification and automatically generates a chat bot that helps the user make API calls. The generated bot is self-documenting, using descriptions from the API specification to answer help requests. Unfortunately, Swagger specifications are not always good enough to generate high-quality chat bots.
This paper addresses this problem via a novel in-dialogue curation approach: the power user can improve the generated chat bot by interacting with it. The result of this interaction is then saved back into the original API specification. This paper reports on the design and implementation of the chat bot compiler, the process of in-dialogue curation, as well as working case studies.
