Care through Social Network Analysis: A Study on Social Isolation Detection and Recommender Systems

Time: 11:00 am – 12:00 pm

Location: Erie Hall, Room 3123


Abstract: Social network analysis (SNA) is a powerful tool for understanding and modelling the relationships between entities in a social system. This talk explores the application of social network analysis, particularly in graph-based recommendation systems. We explore the intersection of data science and artificial intelligence, focusing on developing AI models.

One significant application discussed in this work is the detection of social isolation within community-based palliative care networks. Social isolation is a critical public health concern, significantly impacting older adults and palliative patients, often worsened by factors such as disease and limited daily capabilities. In response to this challenge, we propose a framework that views social isolation as an outlier detection problem within community-based social graphs. Our approach involves mapping the network to an attributed weighted social graph, where each patient is intricately linked to informal and formal care providers. Using formulae and indices, the societal norm is extracted by evaluating structural connections and quality-of-life features. The algorithm is validated using real-life data from the Windsor Essex Compassion Care Community (WECCC) and synthetic social graphs.

Future work will focus on developing a recommender system to suggest community resources to individuals to mitigate the impact of social isolation. We discuss the potential integration of deep learning and sequential recommender systems. The main goal is to identify and recommend the optimal combination of community support events and practices based on multiple objectives and criteria.
