SocialPersona: Benchmarking Personalized Profiling and Response with Multimodal Social-Media Context
The authors introduce SocialPersona, a benchmark designed to evaluate whether multimodal large language models (MLLMs) can recover revealed preferences from longitudinal social-media timelines and use them in dialogue. This work addresses the limitation of current evaluations that focus only on explicit memory by testing a model's ability to infer interests from natural multimodal traces.
