title: Text mining and analysis of "data available upon request" statements in scientific articles. (Data)

description: This Zenodo record contains the data and data tables used to analyse the use of “data available upon request” style statements in the genomics, genetics, and bioinformatics literature (2010–2025).

This dataset accompanies the corresponding code repository (GitHub) and the automatically archived code release on Zenodo (Code - Text mining and analysis of "data available upon request" statements in scientific articles.).

The analyses quantify how often the "upon request" wording is used, how it changes over time, and how it relates to other signals of open science support at the article and journal level.

Overview

Using full-text XML articles from the PubMed Central Open Access Subset, the pipeline detects “upon request” sentences, classifies them (vague versus linked to explicit access mechanisms or legitimate restrictions), and extracts several open science indicators (for example public repository deposition, dataset identifiers, code availability signals, protocol sharing, and source data mentions). The tables in `2.data/` are the inputs and derived metadata used to run the analyses and reproduce the manuscript figures and summary statistics.
