用可视化论文图谱探索学术文献
每张图谱把种子论文放在最相关的文献之间，并按共同被引或共享参考文献的密度聚类。
分别展示论文所依据的基础工作与其后的发展，非常适合追溯研究脉络。
可从论文标题、DOI、URL 或会议论文集链接开始，用手头已有的信息直接进入图谱。
当需要具体信息而非全局概览时，可通过排序列表按相关性浏览相关文献。
Rayyan is an AI-assisted systematic review platform that helps research teams import, deduplicate, screen, extract data from, and report on literature across the full evidence synthesis workflow.
The Systematic Auto-Resolver deduplicates up to 200,000 references using your own inclusion and exclusion protocol with one click.
ResearchPilot delivers zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and auto-extraction to speed up search, screening, and data capture.
Work through title, abstract, and full-text screening with inclusion and exclusion tagging, conflict resolution, and blinded reviewer modes.
Capture structured study data with configurable extraction fields, apply PICO frameworks, and export results with auto-generated PRISMA diagrams.
