3 Bibliography buildingBibliometrics Topic / keywordCitation metrics AuthorJournal ranking Cited referencesImpact factors Shared referencesData by discipline Save & exportUniversity metrics

4 Coverage 12,600 refereed journals Titles of non-English journal articles translated Abstracts of non-English language articles available in English from 1990 Social Sciences & Humanities databases

5 Search Phrase searching – eg. “inflation targeting” finds this exact phrase Author names – Last name, followed by first, or initial Lemley, Mark Search operators http://images.webofknowledge.com/WOK46P9/help/WOS/ht_operators.html

6 New Web of Science Consolidated search field Simplified navigation and grouping of functional controls Multiple expanded search fields available

7 Cross-links from Web of Science to Google Scholar Google Scholar automatically displays link to full text at user’s university if available based on IP address.

10 5-year Impact factor The 5-year Journal Impact Factor: – "The 5-year journal Impact Factor is the average number of times articles from the journal published in the past five years have been cited in the Journal Citations Report year. It is calculated by dividing the number of citations in the Journal Citation Report year by the total number of articles published in the five previous years." http://admin-apps.webofknowledge.com/JCR/help/h_impfact.htm

12 h-Index Developed by Jorge E. Hirsch 'An index to quantify an individual’s scientific research output'An index to quantify an individual’s scientific research output – Proceedings of the National Academy of Sciences, 102 (46) November, 2005

13 Calculation H-index of 3 means there are 3 items that have 3 citations or more. "This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited."

14 h-Index

15 Controversies Book-intensive disciplines 'under-weighted' Number of authors per work not factored. Multi- authored papers favoured Variation of citation numbers/patterns in different disciplines and sub-disciplines not factored No citation context: eg. 'routine' background/theory citations and 'bad science' citations Cannot account for bias or 'author cartels'

16 Caveats Web of Science a database of refereed article records ‘Main’ articles sometimes mis-classified as ‘reviews’ Language coverage Thomson Reuters does not correct/change metadata Abstracts only since 1992 Author names – variations/diacritics Citation because of ‘controversial’ or ‘bad science’ Differences between disciplines: citation patterns.

17 Database caveats The journal selection process – "Many excellent regional journals target a local, rather than an international, audience. Therefore, the emphasis on extensive international diversity is less than for internationally focused journals."

18 Scientometrics as sub-discipline Key in WoS: “bibliometrics"

31 U-Multirank (EC funded) U-Multirank is a new multidimensional, user- driven approach to international ranking of higher education institutions. It compares the performances of universities in 5 dimensions: (1) teaching and learning (2) research (3) knowledge transfer (4) international orientation (5) regional engagement http://www.umultirank.org/#!/methodology?trackType=home&sightMode=undefined

32 The Debate Authors’ societies / language groups Briefings (eg) ANVUR (Roma) 17 November La valutazione della ricerca nelle Humanities and Social SciencesANVUR (Roma) 17 November Chronicle of Higher Education Times Higher Education
