We are a team of student researchers from the IRLab at Emory University (http://ir.mathcs.emory.edu/ ) with enthusiasm in the advancement of conversational AI. We specialize in Information Retrieval, Question Answering, and Web Search, as indicated by our team name, IRIS (Information Retrieval & Informative Suggestion). Our goal is to create an informative search-oriented agent with the capacity of conducting fluent and entertaining conversations. Our team consists of several Ph.D. and undergraduate students with diverse academic backgrounds, such as mathematics, computer science, and engineering. We are excited about the opportunity to extend the state of the art in conversational search, while stress-testing our ideas in an real-world challenge.
