Cited references and Medical Subject Headings (MeSH) as two different knowledge representations: clustering and mappings at the paper level

Abstract: 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, we provide methods and routines that make MeSH terms amenable to broader usage in the study of science indicators: using Web-of-Science (WoS) data, one can generate the matrix of citing versus cited documents; using PubMed/MEDLINE data, a matrix of the citing documents versus MeSH terms can be generated analogously. The two matrices c… Show more

“…Limited evidence exists specifically regarding hyperoxia in trauma patients. Based on our review of the literature via a systematic Medical Subject Headings search, prior studies are limited to mostly traumatic brain injury (TBI) patients and do not account for cumulative oxygen exposure ( 15 ).…”

“…The selection of terms with a minimum of ten occurrences is attributed to the fact that the network visualization becomes clear and avoids overlapping of labels. Furthermore, selecting ten or more than ten terms help to perform core set analysis (Leydesdorff et al , 2016) with an ease of interpretation. For example, Van Eck and Waltman (2017) selected minimum of ten terms for cluster creation with the reason that “when the number of objects to be clustered is relatively limited, analyzing and interpreting the results obtained from a clustering technique usually does not cause any significant difficulties.” The top 10 keywords with the highest frequency are; “Cov” (694), “Coronavirus” (601), “Virus” (346), “Hospital” (254), “Impact” (218), “Approach” (175), “Outcome” (172), “Pneumonia” (169), “Development” (137) and “Challenge” (127).…”

“…As the names of drugs and diseases in different datasets often vary in their vocabulary, this required consideration and adjustment for standardization. For example, the drug names in the indication dataset, side effect dataset, and contraindication dataset were from DrugBank ( Wishart et al, 2007 ), ATC ( Miller and Britt, 1995 ), and RxNorm ( Nelson et al, 2011 ), respectively, while the corresponding disease names in these three datasets were from OMIM ( Hamosh et al, 2005 ), UMLS ( Bodenreider, 2004 ), and MeSH ( Leydesdorff et al, 2016 ), respectively. To unify the drug and disease names, we mapped their names to Unified Medical Language System (UMLS) ontology.…”
