1st Workshop on Conversational Interaction Systems (WCIS)


Conversational interaction systems such as Alexa, Google Assistant, Siri, and Cortana have become very popular over the recent years. Such systems provide a conversational interface to a wide variety of content and on the web and in turn for IR systems. Some interactive systems like Facebook Portal and Echo Show also involve challenges with language understanding in combination with vision. Research challenges such as Dialogue System Technology Challenges and Amazon Alexa Prize have continued to inspire research in conversational AI bringing together researchers from different communities such as speech recognition, spoken language understanding, reinforcement learning, information retrieval, language generation, and multi-modal question answering.

This workshop aims to bring together researchers from academia and industry to discuss the challenges and future of conversational agents and interactive systems. We will highlight applications like recommendation systems, search, knowledge graph induction, multi-modal interaction and web question answering. The workshop will include talks from senior technical leaders and researchers to share insights associated with building conversational systems at scale. We will issue an open call for papers and will prioritize innovative and impactful contributions. Accepted papers will be presented through contributed talks or poster presentations. We will end the workshop with an open panel discussion consisting of leading researchers.
