Look Who’s Talking

Towards Engaging Long-Term Interactions with Conversational Agents

About the project

Look Who’s Talking is an interdisciplinary collaboration between three universities from the Netherlands, funded by the Dutch Research Council (NWO), working together to develop and test a new generation of conversational agents (chatbots) which can engage with humans in long-term motivational interactions. The ​ main aim of this project is to create and field-test chatbots designed to develop and foster long-term engaging and human-like conversations with humans for two technologically and linguistically diverse domains (smoking cessation and promotion of safe sex, respectively) based on recent insights from artificial intelligence, computational linguistics, humanities, and social sciences with expertise from our societal partners. Additionally, we will study if and how people build up a social relationship with such more advanced chatbots, and what the ethical implications of communication with such health chatbots are.

Chatbots

Roby the smoking cessation bot

Roby’s main function is getting to know smokers’ behaviour by a conversational assessment. It also provides personalized normative feedback and discusses with smokers potential reasons to quit smoking. We “trained” Roby with motivational interviewing techniques and skills, to be a helpful addition in motivating smokers to quit!

MISH the sexual health bot

MISH is a text-based chatbot that primarily makes use of motivational interviewing (MI) techniques to promote sexual health. This prototype has been designed to address condom use. While the intended target population is heterosexual couples in a steady relationship, initial testing will be conducted with individuals.
