What is Connected Papers?
Connected Papers builds visual similarity graphs from academic papers, helping researchers discover relevant prior works, derivative literature, and field trends across disciplines.
Connected Papers is an academic exploration platform designed to help researchers visually analyze scientific literature. Powered by the Semantic Scholar database spanning hundreds of millions of papers across disciplines, the service generates visual graphs based on co-citation and bibliographic coupling rather than direct citation chains alone. Starting from a single seed paper or search query, the tool constructs a network graph showing closely related publications, their relative influence, and their connections. Researchers can toggle between distinct analytical perspectives, including a Prior Works view to identify foundational ancestor papers and a Derivative Works view to locate subsequent literature reviews and state-of-the-art advances. In addition to single-paper graphs, the system supports multi-origin graphs, saved paper lists, and graph history tracking. Its database covers natural sciences, machine learning, medicine, humanities, and social sciences, making it a cross-disciplinary utility for literature reviews, bibliography assembly, and landscape exploration.
Unlike standard search engines that return linear lists of citations, Connected Papers visualizes citation clusters and similarity networks, surfacing seminal prior papers and recent derivative works without requiring manual bibliography tracing.

Workflow
How Connected Papers works
- Enter a paper title, DOI, or search topic into the search bar.
- Connected Papers analyzes co-citations and bibliographic metrics from the Semantic Scholar database.
- A graph network is rendered showing related papers, clustering strength, and connection intensity.
- Explore ancestor papers via Prior Works or recent literature surveys via Derivative Works.
- Save papers to your account or launch new multi-origin graphs to broaden the scope.
