Library
Web of Knowledge(Institute for Scientific Information)
• ISI Web of Science
• Web of Science top tab (default)
–Reference guide (11 languages)
Library
Bibliography-buildingSearching & Citations
• Topic• Author• Cited references• Breakout (eg. by year)
• Export• Times cited
• Citation report• h-Index• Search history• Alerts• Mapping citations• Scientific Web beta
Library
Phrase definition & authors
• Phrase Searching
eg. “inflation targeting” finds records containing this exact phrase
• Parentheses
Use parentheses to group compound statements. For example:
(Eurozone OR Euro) AND (“inflation targeting”)
• Author Name
Enter the last name first, followed by a space and up to five initials.
- Artis M* finds: Artis M, Artis JM, Artis Michael &c.
- Artis finds all authors with the last name Artis
Library
h-Index
• Developed by Jorge E. Hirsch'An index to quantify an individual’s scientific research output'– http://www.pnas.org/content/102/46/16569.abstract
Proceedings of the National Academy of Sciences, 102 (46) November, 2005
Library
Calculation
• H-index of 7 means there are 7 items that have 7 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."
Library
Institutional SearchRankings
• Times Higher Education– 2011 World University Rankings
• Using 'Advanced Search'• OG= Organisation
Library
World University RankingsTimes Higher Education, 6 October 2011
• The Learning Environment (30%)• Citations / Research Influence (30%)• Research volume, income, reputation (30%)• International outlook: people, research (7.5%)• Industry Income: innovation (2.5%)
pp.28-29, Times Higher Education rankings supplement, 6 October 2011
Library
Some Caveats: international coverage
• 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."
Library
Caveats…• ‘Main’ articles sometimes mis-classified as ‘reviews’• Language coverage – diacritic errors in citation • 'Web of Science' does not correct/change metadata• Abstracts only since 1992• Not all series are indexed – eg. NBER
• Author names – variations• Citation because of ‘controversial’ or ‘bad science’
Library
Upgrades
– Book Citation Index – Scientific Web Plus (beta) in development
• Top right of records' screen
– More normalisation for disciplines– Collaboration indicators (geo/institutional)
Library
Bibliometrics
• Data about publications• Citation patterns
• Impact factors
• Quantitative analysis
Library
Bibliometrics Usage
• Funding authorities• University administrators• Information science• Scientific ‘competitiveness’
– eg. UNESCO Science Report
• As indicators in ‘core’ research• Bibliometrics as a ‘sub-discipline’
Library
Academic CommunicationPaper and Electronic
• Books & e-Books• Journals & e-Journals – licensed/open access
• ‘Advanced’ OA / Web dissemination• Example of PLoS article (Nov. 2011)
Library
