Overview

The node fetches a list of academic papers similar to a specified paper using its identifier. It is useful for researchers or academics who want to discover related work based on a known paper. For example, given a DOI or other paper ID, the node returns similar papers, optionally including citation graph edge data, helping users explore related literature efficiently.

Use Case Examples

  1. Finding similar research papers to a given DOI to expand literature review.
  2. Discovering related academic articles based on an ArXiv or PubMed ID.

Properties

Name Meaning
Fields to Return Specifies which fields to include in the results, such as title, authors, year, abstract, DOI, URL, PDF URL, date, total citations, total references, provider information, and raw provider-specific metadata. Leaving this empty returns all default fields.
Paper ID The identifier of the paper to find similar papers for. Supports various ID types such as DOI, Semantic Scholar ID, ArXiv ID, PubMed ID, OpenAlex ID, or URL. This is a required field.
Limit Maximum number of similar papers to return, with a minimum of 1 and maximum of 100.
Include Edges Boolean flag indicating whether to include citation graph edge data (citingIds, citedByIds) in the results.

Output

JSON

  • title - Title of the similar paper.
  • authors - Authors of the similar paper.
  • year - Publication year of the similar paper.
  • abstract - Abstract of the similar paper.
  • doi - DOI of the similar paper.
  • url - URL of the similar paper.
  • pdfURL - PDF URL of the similar paper.
  • date - Date associated with the similar paper.
  • totalCitations - Total number of citations the similar paper has received.
  • totalReferences - Total number of references cited by the similar paper.
  • provider - Provider name of the paper metadata.
  • providerURL - Provider's URL for the paper.
  • providerData - Raw provider-specific metadata for the paper.
  • citingIds - IDs of papers citing the similar paper (included if 'Include Edges' is true).
  • citedByIds - IDs of papers cited by the similar paper (included if 'Include Edges' is true).

Dependencies

  • An API key credential for the PDF Vector API

Troubleshooting

  • Ensure the Paper ID is correctly formatted and supported (DOI, Semantic Scholar ID, ArXiv ID, PubMed ID, OpenAlex ID, or URL).
  • If the API returns errors, check the API key credential and network connectivity.
  • Limit parameter must be between 1 and 100; values outside this range may cause errors.
  • If 'Include Edges' is enabled, the response may be larger and slower; consider disabling if performance issues occur.
