SocialPersona: Benchmarking Personalized Profiling and Response with Multimodal Social-Media Context
arXiv:2606.26654v1 Announce Type: new Abstract: Personalized language-model assistants are often evaluated through a memory lens: can a model recall preferences users have explicitly stated in dialogue? More comprehensive personalization demands a harder capability -- inferring what users care about from the multimodal traces they naturally leave behind. We introduce SocialPersona, a benchmark for evaluating whether multimodal large language models (MLLMs) can recover revealed preferences from longitudinal social-media timelines and use them in dialogue. Built from longitudinal timelines of 17
The proliferation of multimodal social media data and the rapid advancements in MLLMs make comprehensive personalized profiling a critical next step in AI development.
This development moves beyond explicit preference recall, enabling AI to infer user needs from passive digital traces, which is crucial for more sophisticated and proactive AI assistants.
AI models will transition from merely remembering user inputs to actively interpreting and anticipating user preferences based on their broader digital footprint.
