A team of students from The Ohio State University developed TacoBot (TAsk-oriented COllaborative taskBOT), which won the 3rd place in the first Alexa Prize TaskBot Challenge. Equipped with cutting-edge natural language processing (NLP) technologies, TacoBot assists its users to complete multi-step cooking and DIY home improvement tasks via a user-centered collaborative multimodal dialogue experience. Feedback from Alexa users guided our research on dialogue systems, such as natural language understanding, conversational search engine, and dialogue response generation.
