Research Paper Overview
Conf-Profile: A Confidence-Driven Reasoning Paradigm for Label-Free User Profiling
Summary
User profiling aims to infer structural attributes from user data. This paper introduces ProfileBench, a benchmark from a real-world video platform with heterogeneous user data and a profiling taxonomy. To address label scarcity and noisy data, Conf-Profile uses a two-stage confidence-driven framework: synthesizing high-quality labels with confidence hints, followed by confidence-weighted voting and calibration. The approach aggregates multiple profile results and confidence scores into a lightweight model, enhanced by confidence-guided unsupervised reinforcement learning. Experiments show significant performance gains, improving F1 by 13.97 on Qwen3-8B.
