Chatbot researchers and practitioners are invited to CONVERSATIONS 2020, a two-day workshop on chatbot research and design. This is the fourth event in the CONVERSATIONS workshop series, where chatbot researchers collaborate and share their work. No registration fee is required for the workshop, and it is a stimulating venue to explore actively this rapidly advancing field.

Due to the corona pandemic, this year’s edition of CONVERSATIONS will be a virtual event. All paper presentations and collaborative activities will be conducted online.

KEY CHALLENGES
Building on the results from previous CONVERSATIONS workshops we outline the following clusters of challenges to be addressed:
1. USER AND COMMUNICATION STUDIES. How do users perceive and communicate with chatbots? To what extent do chatbot features, dialogue style and content influence these perceptions? What is the impact of personal, social and cultural factors on chatbot uptake and use?
2. CHATBOT USER EXPERIENCE AND DESIGN. How to understand, investigate and strengthen chatbot user experience? How to improve chatbot interface and interaction design? How to design for novel and improved chatbot user experiences? How to conduct user-centred evaluations?
3. CHATBOT FRAMEWORKS, PLATFORMS AND APPLICATIONS. Research-based knowledge on current and future frameworks and platforms for chatbot development and delivery. Challenges pertaining to data access, NLP, and context awareness. Chatbot training. Chatbots that learn through use. Generative chatbots. Multimodal chatbot interaction.
4. CHATBOTS FOR COLLABORATION. How to understand and design chatbots in networks of humans and intelligent agents? For example, for social networks, teamwork, or service provision.
5. DEMOCRATIZING CHATBOTS - CHATBOTS FOR ALL. How to use chatbots to improve availability, accessibility, effectiveness, and efficiency to information and services? How can chatbots bridge digital divides. How to design inclusive chatbots?
6. ETHICS AND PRIVACY IN CHATBOTS. Ethical and privacy implications of chatbots. Design for ethics and privacy in chatbots. Trust in chatbots. Trustworthy chatbot design. Addressing unethical chatbot use. Malicious bot detection.
