Automated Citation Network Builder for Academic Papers

This n8n workflow automates the process of building a citation network among academic papers based on input paper IDs such as DOIs or PubMed IDs. Starting with a set of seed papers, it fetches detailed information including titles, authors, publication years, and citation counts. The workflow then retrieves citing papers within a specified depth, creating a network graph that visually illustrates the citation relationships. It constructs nodes and edges representing papers and their citations, combines data from multiple papers, and exports the results as a JSON file and a GEXF format compatible with visualization tools like Gephi. This workflow is particularly useful for researchers who want to analyze citation patterns, identify influential papers, or visualize scholarly knowledge landscapeswithout manual effort.
