Table_4_Introducing the open biomedical map of science.csv

This article introduces work in progress to develop a new, open biomedical map of science (OBMS) using the PubMed citation database. The new science map represents bimodal network relationships between journals and medical subject heading (MeSH) descriptors, based on a journal's articles indexed in the MEDLINE component of PubMed. We review the current efforts to use PubMed data in science of science studies and science mapping. As part of the development process, we compare the journals indexed in PubMed with journals included in the 2011 UCSD map of science to establish a baseline of disciplinary coverage of PubMed for the period 2009–2019. Journal article frequency is analyzed to establish the minimum number of citations required by a journal for inclusion in a map of science. A prototype OBMS is presented, and we discuss the strengths and weaknesses of the OBMS, as well as the next steps for using and productizing this new open map for general and free usage.

本文介绍了一项基于PubMed引文数据库开发新型开放生物医学科学图谱（Open Biomedical Map of Science, OBMS）的在研工作。该新型科学图谱基于PubMed的MEDLINE数据库模块中收录的期刊论文，构建了期刊与医学主题词（Medical Subject Headings, MeSH）之间的双峰网络关联关系。本文综述了当前在科学学研究与科学图谱构建中使用PubMed数据的相关探索。作为开发流程的一部分，我们将PubMed收录的期刊与2011年UCSD科学图谱所纳入的期刊进行对比，以确立2009年至2019年期间PubMed的学科覆盖基线。本研究通过分析期刊论文发文频次，确立了期刊被纳入科学图谱所需的最低引文量标准。本文展示了OBMS的原型系统，并讨论了该图谱的优势与局限，同时阐述了将这一新型开放图谱进行产品化以实现通用免费使用的后续推进方向。
