  1. POLITICS: Pretraining with Same-story Article Comparison for Ideology Prediction and Stance Detection (2022 · 70 citations)
    Measuring political ideology from text is central to political science, yet no general tool works reliably across text genres.
  2. ThinkPrune: Pruning Long Chain-of-Thought of LLMs via Reinforcement Learning (2025 · 64 citations)
    Reasoning models trained to produce long chains of thought often generate redundant, inefficient reasoning, which inflates inference cost.
