  • 8,000 science journals2,600 social science journalsSearch by journal title or by discipline (or linked from article page in Web of Science)Rank alphabetically (default) or by Total cites, Impact factor, Immediacy factor and more...http://ezproxy.canterbury.ac.nz/login?url=http://isiknowledge.com/jcr
  • Open access, developed in SpainUses the PageRank algorithm – attributes different weight to citations depending on the prestige of the citing journal, without influence of self-citationsLarger data source than ISIUsed by SCOPUShttp://www.scimagojr.com/
  • Pro: measure simultaneously the quality and steadiness of scientific output, rather than just total number of papers (does not account for quality) or total number of citations (can be disproportionately affected by participation in a single publication of major influence, or having many publications with few citations each).Con: doesn’t account for number or order of authors; fields vary in number of references cited; bounded by number of publications. May produce inconsistent results, eg “if two researchers with a different h-index co-author a paper together, it may lead to a reversal of their position in an h-index based ranking”.Ignores citations over and above what is needed to obtain a certain h-index. Less useful to measure academic achievement of junior academics
  • Can underestimate true citation impact – cited reference search does include citations by non ISI journals (first author only)1. Cited Search for single paper – oxley l* - econ rec – 1995 - Create citation mapCitation alerts2. Citation reportwoodward l – canterbury – View records – create citation reportH-index Citation distribution per year Total Times Cited count Average Times Cited count 3. Researcher ID – show example e.g. les oxley A6075-2008 – register to join
  • Introduced in 2004. Citation data is shown only for the documents from the publication year 1996 onwards, altho older records are listed. 18,500 peer reviewed (cf 12,000 in WoS)Good for science and social sciences, weaker in humanities, usually retrieves more citations?Better systems for identifying unique authorsUse author finder – e.g. woodward l (WoS h-index of 15, h-index of 26 in Scopus)Can display their publications or go straight to View citation overview and graphs of h-index, citations and publicationsRegister for alerts
  • Not very open about its sources – unclear what sources are Studies have found that most of the citations uniquely found in Google Scholar are from refereed sources.Uneven coverage across disciplines e.g. Natural and health sciences well covered in ISISS, humanities benefit from coverage of books, conference proceedings and wider range of journalsWeaker for older publications – but improving as journal back runs are posted on the webScholars have done studies on each discipline Open access – open to spam
  • Measures 3 metricsH index1-10 indexTotal cites Can have a public or private profileShow My profile and search for Michael hall
  • Perform an author search with initial & surname in quotes. Add the years you have been publishing and limit by subject area.You may need to remove false hits.
  • Harzing has written extensively about metrics. PoP gives you more measures than WoS, Scopus or even GS.G-index (Egge) – gives more weight to highly cited articlesVariations of the H-index designed to compensate for co-authorship (so is less than the h-index).AWRC - age weighted citation rate
  • Another open access model – publish in subscription journal but put a copy in open access repository. Indexed by Google Scholar so high visibility.Anything in the research repository has basic download stats available.To add items, when you’re submitting through Profile it’ll ask you to upload documents – if you have it upload published version for PBRF verification and preprint or postprint for repository.*We’ll* do the copyright checking, so you don’t need to worry, we won’t upload anything we’re not allowed to.If you have lots of items you want to upload and no time, contact Grant Barrie – he’s happy to work something out.

  • Have you been cited? Impact measures for PBRF

    1. 1. Have you been cited? “In 1955, it did not occur to me that “impact” would one day become so controversial. Like nuclear energy, the impact factor is a mixed blessing. I expected it to be used constructively while recognizing that in the wrong hands it might be abused.” Eugene Garfield
    2. 2. Today Journal ranking The h-index Finding citation data on:  Web of Science  Scopus  Google Scholar  Publish or Perish Research repository
    3. 3. Journal Citation Reports
    4. 4. SCIMago Journal Rank (SJR)
    5. 5. h-index “A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np − h) papers have no more than h citations each.”
    6. 6. Web of Science Limited to 12,000 WoS journals Strong in natural and health sciences, medicine, chemistry and physics Weaker in social sciences & humanities Less coverage of conferences, books & non-English sources Variations in author names
    7. 7. Scopus Introduced in 2004 by Elsevier 18,500 peer-reviewed journals (including 1,800 Open Access journals) Strong in science, social sciences, weak in humanities
    8. 8. Google Scholar Free, quick, easy to use and comprehensive Includes conference papers, theses, books, chapters etc Not very open about sources Weaker for older publications
    9. 9. Google Scholar Citations My Citations – set up a profile to automatically retrieve publications and citations Includes citations counts, H-Index & i10 Index Future publications and citations automatically updated
    10. 10. Publish or Perish Developed by Anne Wil-Harzing in 2006 Based on Google Scholar data Open source softwarehttp://www.harzing.com/pop.htm
