    Which metric to use?

    What level am I assessing? Article, Journal, Researcher, Institution, etc. What type of impact am I assessing? Scientific, Clinical, Societal, Educational, etc. What methods are available based on above? Quantitative: citation, usage, media, h-index, SNIP, SJR, etc. Qualitative: Peer-review, etc. Bibliometrics (quantitative measures used to asses research output) Basic premise = Citation is a form of endorsement Bibliometricians agree that no single metric can effectively capture the entire spectrum of research performance because no single metric can address all key variables

  • Слайд 21

    Which journal is best? They are all the best – all the top of their subject categories *Journal Citation Reports 2009 Journal Impact Factor

  • Слайд 22

    Vanclay, J, Impact factor: outdated artefact or stepping-stone to journal certification, Scientometrics, Volume 92, Issue 2 (August 2012) “[Publishers should] Greatly reduce emphasis on the journal impact factor as a promotional toolideally by ceasing to promote the impact factor or by presenting the metrics in the context of a variety of journal based metrics … that provide a richer view of journal performance” - From The San Francisco Declaration on Research Assessment (DORA) http://am.ascb.org/dora/ Journal Impact Factor

    SJR: SCImago Journal Rank

    Prestige metric: Prestige transferred when a journal cites Citations are weighted depending on where they come from A journal’s prestige is shared equally between its citations Life Sciences journal High impact, lots of citations One citation = low value Arts & Humanities journal Low impact, few on citations One citation = high value SJR normalizes for differences in citation behaviour between subject fields

    Books expansion initiative

    Further benefits: Improve Arts & Humanities coverage in Scopus Enhance discoverability of books and book content Measure the impact of books Increase accuracy of Author Profiles

  • Слайд 33

    Scope and selection of books expansion

    Will cover scholarly books that represent fully-referenced, original research or literature reviews. Book selection via a publisher-based approach (no suggestions). All books from selected publishers deemed “in scope” will be selected for coverage. Selection depends on: Reputation and impact of the publisher Size and subject area of the books list Availability and format of the book content Publication policy and editorial mission Quality of published book content
