This book presents the outcomes of the 9th International Workshop on Spoken Dialogue Systems (IWSDS), Towards creating more human-like conversational agent technologies. It compiles and provides a synopsis of current global research to push forward the state of the art in dialogue technologies, including advances in the context of the classical problems of language understanding, dialogue management and language generation, as well as cognitive topics related to the human nature of conversational phenomena, such as humor, empathy and social context understanding and awareness.
Introduction.- Language and Social Context Understanding.- Dialogue Management and Pragmatic Models.- Dialogue Evaluation and Analysis.- End-to-end Systems.- Empathic Dialogue Systems.- Humor in Dialogue Agents.- Chat-oriented Dialogue Systems.- Question Answering and other Dialogue Applications.
Prof. Luis Fernando DHaro is an Associate Professor at Universidad Politécnica de Madrid (ETSIT, UPM) in Spain and a member of the Speech Technology Group. His current research mainly focuses on spoken dialogue and natural language processing systems, as well as on different applications of spoken language technologies (especially language and speaker identification), and he has written has more than 15 international publications on dialog systems. He co-led the International Dialog State Tracking Challenges (DSTC) in 2015 and 2016 and is a co-organizer of the DSTC7 challenge, with over 220 registered participants. Since 2015, Prof. DHaro has co-organized the Wo-Chat series of workshops, which have the common goal of advancing chatbot systems and their automatic evaluation.
