Acknowledged organizations in biomedical and life sciences research: a large-scale analysis of classification, citation, and topic evolution.

This article systematically analyzes the roles and impacts of different types of organizations acknowledged in biomedical and life sciences research publications. Using a large dataset from PubMed Central, organizations were categorized into universities, enterprises, research institutions, private foundations, government agencies, and others, with government agencies and universities being the most frequently acknowledged. Citation analysis revealed that papers acknowledging enterprises and research institutions tend to have higher citation impacts than those acknowledging universities, while the National Institutes of Health (NIH) emerged as a central and influential funding organization within co-acknowledgement networks. Topic modeling showed that funding priorities align with distinct research themes across organization types, such as enterprises focusing on pharmaceutical support and government agencies on public health initiatives. The study highlights the complementary value of acknowledgements in understanding research collaboration, funding influence, and scholarly impact beyond traditional citation metrics.
