PRODUCT OVERVIEW
What is Connected Papers?
Connected Papers is a visual research tool for researchers and applied scientists who need to find and explore papers relevant to their field. Enter a paper identifier such as a DOI, arXiv, Semantic Scholar or PubMed URL, or a title, and it builds a graph of similar papers drawn from the Semantic Scholar corpus. Papers are arranged by similarity based on co-citation and bibliographic coupling, so related works cluster together even without direct citations. Prior Works and Derivative Works views help locate ancestor studies, literature reviews and newer state-of-the-art papers. Use it to get an overview of a new field, check for missed important papers, or fill gaps in a thesis bibliography. A free tier includes all features with 5 graphs per month; Academic and Business plans unlock unlimited graphs.
