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

- 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

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)
