Dr. Leung’s is currently leading a project to develop an Artificial Intelligence (AI)-based system to support safety and patient outcomes for a national online cancer support group service. The system, based on Deep Learning and Natural Language Processing algorithms, will be designed to act as a “co-group facilitator” to assist therapists during the sessions to keep track of group participants’ progress while gaining insights into treatment processes. The AI system will be used to conduct sentiment analysis using group discussion text, and generate analytics including the context of the posts and emotion trajectory. These information will be used to train new online therapists and to facilitate client-treatment matching in supporting a stepped-care model. This project will transform the way psychosocial intervention is delivered and evaluated, while enhancing safety and uptake of online supportive services, which especially supports those living in non-urban settings, and other access barriers.
