Data-mining the Foundational Patents of Photovoltaic Materials: An application of Patent Citation Spectroscopy
Jordan Comins, Loet Leydesdorff
We apply Patent Citation Spectroscopy (PCS)--originally developed as Reference Publication Year Spectroscopy for studying landmarks and milestones in scientific literature--to pate…
Patent Citation Spectroscopy (PCS): Algorithmic retrieval of landmark patents
Jordan A Comins, Stephanie A Carmack, Loet Leydesdorff
One essential component in the construction of patent landscapes in biomedical research and development (R&D) is identifying the most seminal patents. Hitherto, the identification…
Synergy in the Knowledge Base of U.S. Innovation Systems at National, State, and Regional Levels: The Contributions of High-Tech Manufacturing and Knowledge-Intensive Services
Loet Leydesdorff, Caroline S. Wagner, Igone Porto-Gomez +2
Using information theory, we measure innovation systemness as synergy among size-classes, zip-codes, and technological classes (NACE-codes) for 8.5 million American companies. The…
Citation algorithms for identifying research milestones driving biomedical innovation
Jordan A. Comins, Loet Leydesdorff
Scientific activity plays a major role in innovation for biomedicine and healthcare. For instance, fundamental research on disease pathologies and mechanisms can generate potential…
Cited References and Medical Subject Headings (MeSH) as Two Different Knowledge Representations: Clustering and Mappings at the Paper Level
Loet Leydesdorff, Jordan A. Comins, Aaron A. Sorensen +2
For the biomedical sciences, the Medical Subject Headings (MeSH) make available a rich feature which cannot currently be merged properly with widely used citing/cited data. Here, w…
Referenced Publication Year Spectroscopy (RPYS) and Algorithmic Historiography: The Bibliometric Reconstruction of András Schubert's Œuvre
Loet Leydesdorff, Lutz Bornmann, Jordan Comins +2
Referenced Publication Year Spectroscopy (RPYS) was recently introduced as a method to analyze the historical roots of research fields and groups or institutions. RPYS maps the dis…
Citations: Indicators of Quality? The Impact Fallacy
Loet Leydesdorff, Lutz Bornmann, Jordan Comins +1
We argue that citation is a composed indicator: short-term citations can be considered as currency at the research front, whereas long-term citations can contribute to the codifica…
RPYS i/o: A web-based tool for the historiography and visualization of citation classics, sleeping beauties, and research fronts
Jordan A. Comins, Loet Leydesdorff
Reference Publication Year Spectroscopy (RPYS) and Multi-RPYS provide algorithmic approaches to reconstructing the intellectual histories of scientific fields. With this brief comm…
Identification of long-term concept-symbols among citations: Can documents be clustered in terms of common intellectual histories?
Jordan A. Comins, Loet Leydesdorff
"Citation classics" are not only highly cited, but also cited during several decades. We test whether the peaks in the spectrograms generated by Reference Publication Years Spectro…
