Features of Connected Papers

Generates visual networks of relationships between papers using co-citation and bibliographic coupling to reveal topic connections.

Presents a force-directed layout for visualization, clustering similar papers to reveal the structure of the literature network.

Supports starting papers input via multiple identifiers—DOI, title, arXiv ID, or paper URL.

Includes 'Prior Works' and 'Derivative Works' views to map the evolution and lineage of research within a field.

Allows you to save generated graphs and view history for easy management and future reference.

Node size typically indicates citation count, while color encodes the publication year, helping quickly assess a paper's influence and recency.

Enables direct viewing of abstracts, citations, and other details from the graph, with interactive exploration.

Data is primarily drawn from the Semantic Scholar corpus, covering hundreds of millions of interdisciplinary papers.

Use Cases of Connected Papers

When researchers enter a new field, to quickly understand the core literature and research landscape.

When writing a paper or a literature review, to help find and assemble relevant references.

Track new findings in a rapidly evolving area (e.g., AI) to avoid missing important papers.

For literature reviews or proposal writing, to visualize the current state and trends of research on a specific topic.

In teaching scenarios, to show students the classic literature and knowledge structure of a topic.

In team-based research, to synchronize and share understanding of literature in a field.

For personal academic management, to collect and organize a literature network closely related to one's research.
