  1. SpellGCN: Incorporating Phonological and Visual Similarities into Language Models for Chinese Spelling Check (2020 · 199 citations)
    Chinese Spelling Check (CSC) means finding and fixing misused characters in Chinese text. Many such errors involve characters that sound or look alike but differ completely in meaning. Earlier systems used confusion sets only to narrow down candidate replacements. They did not model how similar characters relate to…
  2. OpenCoder: The Open Cookbook for Top-Tier Code Large Language Models (2025 · 81 citations)
    Most open code LLMs publish only their weights. Their training data, cleaning pipelines and training recipes stay hidden, which makes it hard for researchers to reproduce results or build strong baselines. OpenCoder addresses this gap. It is a code LLM family released with everything needed to rebuild it: weights…
