筆記與文獻之間的雙向連結建立視覺化關係圖譜，並可匯出為 Neo4j 友善格式。
Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2). It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.
