Access and extract data from over 250 million scientific research papers through the OpenAlex Scientific Research and Citations Scraper API, which provides information on academic authors, DOI citations, institutional affiliations, and links to open-access PDF files from the comprehensive OpenAlex knowledge graph.
The OpenAlex API returns comprehensive bibliographic metadata for scientific research papers, including information on authors, DOI citations, publication dates, citation counts, institutional affiliations, and links to open-access PDF files.
Key fields in the response include "id," "title," "status," "result," "inputReceived," and "data," which contains attributes like "relevanceScore," "summary," and "timestamp."
Users can customize their requests using parameters such as "searchQuery," "publicationYear," "hasOpenAccess," and "maxPapers" to filter and limit the results.
The response data is structured as a JSON array, with each entry containing metadata about a specific research paper, including its attributes and relevant scores, making it easy to parse and analyze.
The data is sourced from the OpenAlex knowledge graph, which curates bibliographic metadata from a wide range of scholarly works, ensuring a comprehensive and reliable dataset.
Typical use cases include conducting literature reviews, performing citation analyses, assessing research trends, and evaluating the influence of specific academic works for researchers and institutions.
Users can analyze the "relevanceScore" to prioritize findings, use "summary" for quick insights, and access "links" to open-access PDFs for further reading, facilitating efficient research workflows.
Data accuracy is maintained through regular updates and quality checks within the OpenAlex knowledge graph, ensuring that the information reflects the latest scholarly publications and citations.
