The research paper "Cura: Curation at Social Media Scale" won the Best Paper Award at CSCW 2023. Explore human-AI collaboration at scale and alternative social media designs for effectively shaping community norms.Elaborate on the curation metaphor: only posts that match curators' tastes (largely upvoted) are published.Design a BERT-based curation system "Cura" to dynamically route posts to the main view or backstage.Design the corresponding interface for interactively defining curators and visualizing curation results.Demonstrate Cura effectively creates different spaces and reduces anti-social content through experiments.

Research paper "Cheater’s Bowl: Human vs. Computer Search Strategies for Open-Domain Question Answering" accepted by findings of EMNLP 2022.Explore how to design better open-domain QA models by learning from human preferences.Design a gamified interface with search engines and collect human data when playing Cheater's Bowl.Analyze differences between human and computer search strategies, including humans prefer precision over recall, humans apply multiple search chains, etc. Propose design suggestions for future models.Design a query-driven QA model based on reinforcement learning that can interact with retrieval systems.

Research paper "HermEs: Interactive Spreadsheet Formula Prediction via Hierarchical Formulet Expansion" accepted by ACL 2023.Explore how NLP models can help increase programming productivity for end users.Design the formula sketch decoder that hierarchically expands non-terminals in the parse tree (CFG).Collect "Formulet'' that contains common 1-to-3-level expansions as the source for expansion prediction.Design an optimization algorithm for the model and provide a mathematical guarantee for its effectiveness.Design a user interface where users write formulas interactively with expansion recommendations.
