| Challenge: | Existing methods for event prediction are incomplete and noisy. |
| Approach: | They propose to use news-related event schemas to extract newsworthy events . they build a demo website and include a video demonstrating the framework . |
| Outcome: | The proposed framework can be applied to a wide variety of newsworthy scenarios. |

| Challenge: | generating and optimizing Hardware Description Languages (HDLs) remains challenging. |
| Approach: | They propose a framework that combines dialectic reasoning with domain-aware code generation and deterministic evaluation to automate RTL optimization. |
| Outcome: | The proposed framework reduces critical path delay and power loss by 25% compared to baselines. |
CAPC-CG: A Large-Scale, Expert-Directed LLM-Annotated Corpus of Adaptive Policy Communication in China (2026.acl-long)
Copied to clipboard
| Challenge: | Adaptive policy communication is a theory of governance in large, decentralized organizations where leaders exercise influence rather than precise control by combining clear and ambiguous instructions to calibrate discipline and flexibility. |
| Approach: | They propose an expert-directed annotation method that integrates codebook design, structured training, a two-step workflow, and LLM-based scaling. |
| Outcome: | The proposed method achieves a Fleiss’ kappa of 0.86 on directive labels, indicating high reliability. |
