Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • WoS and Scopus have specific deficiencies including inconsistencies of journal coverage, inaccuracy of subject classification schemes, missing citation information or citation links, incorrect and missing DOI numbers, duplicate entries, and inconsistent publication dates.

    “Meanwhile, other authors discussed more specific deficiencies of the DBs, such as inconsistencies of journal coverage [63], the accuracy of subject classification schemes [64], missing citation information or citation links [40,65,66], incorrect and missing DOI numbers [53,67-69], duplicate entries [30], and inconsistent publication dates [53].”
  • In a large-scale comparison of WoS and Scopus subject classification schemes, WoS performed significantly better than Scopus, especially regarding cases of journals with weak relations to the categories they are assigned to.

    “The analysis showed that WoS performs significantly better than Scopus, especially regarding the cases of journals with weak relations to the categories that they are assigned to.”
  • The number of such journals was higher in Scopus compared to WoS.

    “the number of such journals was higher in Scopus as compared to WoS”
  • Scopus uses a two-level classification: four major disciplines (Life Sciences, Physical Sciences, Health Sciences, Social Sciences and Humanities), subdivided into 27 categories, further broken down into more than 300 subject fields based on ASJC.

    “Scopus uses classification of two levels. All of the sources are divided into four major disciplines: Life Sciences, Physical Sciences, Health Sciences, and Social Sciences and Humanities. These disciplines are subdivided into 27 categories, which are further broken down into more than 300 subject fields, based on All Science Journal Classification (ASJC)”
  • The situation of journals showing strong relations to categories they are not assigned to was less pronounced in both DBs, and the difference between WoS and Scopus was far less noticeable.

    “the situation of journals showing strong relations to the categories that they are not assigned to was less pronounced in both DBs, and the difference between WoS and Scopus was far less noticeable”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
