Connected Papers is an online scholarly literature discovery platform that uses visual graphs to analyze the relationships between papers via citations and semantic connections, helping users quickly discover and understand literature networks in a given field.
The tool primarily relies on co-citation and bibliographic coupling to assess similarities between papers by measuring overlap in citation relationships, and presents them as a force-directed visualization.
There are free and paid versions. The free plan allows up to 5 graph generations per month; paid plans offer unlimited graph generation, with academic and commercial options.
Supports starting inputs via DOI, arXiv ID, title, Semantic Scholar or PubMed links, among other identifiers.
Mainly sourced from the Semantic Scholar paper corpus, covering hundreds of millions of interdisciplinary papers.
Primarily useful for university researchers, students, teachers, and anyone needing in-depth literature research and scholarly exploration.
Node size usually represents citation count, while color typically encodes the publication year, helping users quickly gauge influence and timeliness.
They state that usage data is collected to improve the service, such as email, username, saved paper lists, and page usage behavior.
