Overview

This dataset contains 738,474 matched records linking arXiv preprints to their published counterparts. It is part of the COMET (Collaborative Metadata) initiative, specifically produced as a result of the matching strategy developed during COMET's pilot phase.

Data Structure

Each record contains the following fields:

• input_doi: The DOI of the ArXiv preprint (format: 10.48550/arxiv.XXXX.XXXXX)
• matched_doi: The DOI of the published work in Crossref that corresponds to the preprint
• confidence: A confidence score (0-1) indicating the reliability of the match
• matched_doi_type: The type of the matched publication (journal-article, proceedings-article, book-chapter, or report )

File Formats

The dataset is available in two formats:

• CSV: 20250615_arxiv_preprint_matching_results.csv
• JSON: 20250615_arxiv_preprint_matching_results.json
