The most cited first (OpenAlex and our library).

1. Opinion Word Expansion and Target Extraction through Double Propagation (2011 · 1,197 citations)
   The paper addresses two linked tasks in opinion mining: growing a domain-specific opinion lexicon and finding the targets that opinions are about, such as product features like "battery life".
2. Towards Scalable Lightweight GUI Agents via Multi-role Orchestration (2026)
   Multimodal LLM agents that operate phone and desktop interfaces work best at large scale, but such models are too costly to run on end-user devices.
