Publication Open Access Bridging the chatbot connection: the role of AI-driven chatbot affordances in e-commerce purchase intentions(Emerald Publishing, 2025-10-05) Yatawara, K.M.B; Sampath, T; Kalupahana, P.L; Rathnayake, S.O; Jayasuriya, N; Rathnayake, NPurpose – This paper explores how AI-driven chatbots, using social support and affordance theories, influence consumer behavior and purchase intentions (PIs) in e-commerce, addressing challenges like limited understanding and security concerns. Design/methodology/approach – A quantitative study was conducted to collect data from 385 customers who had interacted with AI-driven chatbots on e-commerce platforms. Purposive sampling was employed to ensure the relevance of the respondents. Partial least squares-structural equation modeling (PLS-SEM) analysis was performed using SmartPLS 4 to test the hypothesized relationships and analyze the data. Findings – The results show a small direct effect of chatbot affordances on PI, with stronger indirect effects via customer satisfaction (CS) and trust. Notably, trust does not directly influence PI, suggesting a reliance on word-of-mouth. Customer engagement (CE) plays a minor mediating role, highlighting the importance of emotional and experiential factors. Originality/value – This pioneering study within the Sri Lankan context addresses the underexplored area of AI-driven chatbots and their influence on PI. Additionally, the study provides nuanced insights into the mediating mechanisms of CS, trust and engagement in the relationship between chatbot affordances and PI.Publication Open Access Study on Factors Affecting Purchase Intention of Fashion Clothes Advertised on Social Media Platforms(Department of Mathematics and Statistics, Faculty of Humanities and Sciences, SLIIT, 2025-10-10) Bandara, S.
