Eighteen teams were selected for the inaugural competition last year. To build their socialbots, the students combined state-of-the-art techniques with their own novel strategies in the areas of natural language understanding and conversational AI. This article reports on the research conducted over the 2017-2018 year. While the 20-minute grand challenge was not achieved in the first year, the competition produced several conversational agents that advanced the state of the art, that are interesting for everyday users to interact with, and that help form a baseline for the second year of the competition. We conclude with a summary of the human conversation have applicability in both work that we plan to address in the second year of professional and everyday domains. The first generation of such assistants -- Amazon's Alexa, Apple's Siri, Google The Alexa Prize competition received hundreds of Assistant, and Microsoft's Cortana -- have been applications from interested universities. After a focused on short, task-oriented interactions, such as detailed review of the applications, Amazon playing music or answering simple questions, as announced 12 sponsored and 6 unsponsored teams opposed to the longer free-form conversations that as the inaugural cohort for the Alexa Prize. The teams occur naturally in social and professional human that went live for the 2017 competition, listed alphabetically interaction. Conversational AI is the study of techniques by university, were DeisBot (Brandeis University), for creating software agents that can engage Magnus (Carnegie Mellon University), in natural conversational interactions with humans.
