让论文构思随文献阅读动态调整，提升创新性与理解深度
LitPivot: Developing Well-Situated Research Ideas Through Dynamic Contextualization and Critique within the Literature Landscape
- 边写边看文献，根据当前想法实时推荐相关论文
- 17位研究者使用后，想法质量更高且对文献掌握更深入
- 适合需要反复打磨研究创意的学者，尤其适合初学者
构思新研究课题难度大，需在区别于已有工作的同时有效继承其成果。这要求研究者不断回顾文献并基于所读内容迭代优化想法；但一旦想法变动，相关文献也随之改变。现有工具支持有限：文献工具仅帮助理解固定文献集，而构思工具则以静态预选论文为评估基准。本文提出‘文献驱动的思路转向’机制——通过文献互动触发研究想法的修订，同时修订也改变相关文献范围。我们实现该机制于LitPivot系统中，支持研究者同步撰写与检验想法。LitPivot会动态检索与当前想法片段相关的论文聚类，并提供基于文献的改进建议。实验室研究（n=17）表明，使用LitPivot的研究者产出的想法评分更高，且自评对文献空间的理解更深入；开放性研究（n=5）揭示了用户如何利用该工具持续演化自身研究构想。
原文摘要 · Abstract (English)
Developing a novel research idea is hard. It must be distinct enough from prior work to claim a contribution while also building on it. This requires iteratively reviewing literature and refining an idea based on what a researcher reads; yet when an idea changes, the literature that matters often changes with it. Most tools offer limited support for this interplay: literature tools help researchers understand a fixed body of work, while ideation tools evaluate ideas against a static, pre-curated set of papers. We introduce literature-initiated pivots, a mechanism where engagement with literature prompts revision to a developing idea, and where that revision changes which literature is relevant. We operationalize this in LitPivot, where researchers concurrently draft and vet an idea. LitPivot dynamically retrieves clusters of papers relevant to a selected part of the idea and proposes literature-informed critiques for how to revise it. A lab study ($n{=}17$) shows researchers produced higher-rated ideas with stronger self-reported understanding of the literature space; an open-ended study ($n{=}5$) reveals how researchers use LitPivot to iteratively evolve their own ideas.
