To address this, we propose ELDER\u2010MATCH, a personality\u2010aware expert system that moves beyond conventional interest\u2010 or need\u2010based matchmaking. By leveraging AI\u2010powered social robots as an interactive interface, our system helps elderly individuals form not just connections, but suitable and sustainable social relationships based on a deeper understanding of their personality and compatibility. We adopted a two\u2010stage framework: (1) a BERT\u2010based natural language processing stage deriving knowledge from conversational analysis to infer Big Five personality traits, and (2) a K\u2010means clustering stage employing a hybrid knowledge representation to identify compatible social connections based on weighted combinations of personality vectors, interests, and geographical constraints. The social robot provides an intuitive, accessible interface for knowledge acquisition and recommendation delivery, tailored specifically to elderly users with varying technological familiarity. The system was evaluated with 83 older adults across multiple community\u2010based settings. In Stage 2, our unsupervised learning approach identified seven distinct social compatibility clusters, each with specific reasoning rules guiding the recommendation engine. The expert system effectively facilitated meaningful social connections, with 76% of accepted recommendations resulting in ongoing relationships at the three\u2010month follow\u2010up. Beyond interests and needs, personality\u2010aware introductions reduce first\u2010meeting friction and improve trust calibration for older adults. We position ELDER\u2010MATCH as a mediator of human\u2013human ties, and we articulate a \u201csunset\u2010by\u2010design\u201d principle whereby the system fades as relationships stabilise. Longitudinal assessments revealed significant reductions in loneliness, expansion of participants' social networks, and notable improvements in psychological well\u2010being. These findings demonstrate that a two\u2010stage, personality\u2010aware expert system, coupled with a user\u2010centric interface, successfully bridges technological capabilities and social needs, advancing elderly social wellbeing through responsible AI application within the AI\u2010for\u2010Social\u2010Good paradigm. In practice, personality\u2010aware introductions reduce first\u2010meeting friction and calibrate trust for older adults\u2014benefits that interest\u2010only systems rarely deliver in sustained relationships.<\/jats:p>","DOI":"10.1111\/exsy.70206","type":"journal-article","created":{"date-parts":[[2026,1,16]],"date-time":"2026-01-16T01:33:47Z","timestamp":1768527227000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>ELDER<\/scp>\n                    \u2010\n                    <scp>MATCH<\/scp>\n                    : A Personality\u2010Aware Expert System for Elderly Social Connection Through\n                    <scp>AI<\/scp>\n                    \u2010Powered Social Robots"],"prefix":"10.1111","volume":"43","author":[{"given":"Hsiao\u2010Ting","family":"Tseng","sequence":"first","affiliation":[{"name":"Department of Information Management, Asian Institute for Impact Measurement and Management National Central University  Taoyuan Taiwan (ROC)"}]},{"given":"Meng\u2010Hua","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Information Management, Asian Institute for Impact Measurement and Management National Central University  Taoyuan Taiwan (ROC)"}]},{"given":"Chih\u2010Yun","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Information Management, Asian Institute for Impact Measurement and Management National Central University  Taoyuan Taiwan (ROC)"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8204-3471","authenticated-orcid":false,"given":"Chia\u2010Lun","family":"Lo","sequence":"additional","affiliation":[{"name":"Department of Health\u2010Business Administration Fooyin University  Kaohsiung Taiwan (ROC)"}]}],"member":"311","published-online":{"date-parts":[[2026,1,15]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12369\u2010020\u201000690\u20105"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1287\/isre.2022.1136"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.4017\/gt.2009.08.02.002.00"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/146144481560415"},{"key":"e_1_2_8_6_1","volume-title":"The Scientific Analysis of Personality","author":"Cattell R.
