WISER: Bibliometrics I Who’s citing you? Angela Carritt & Juliet Ralph March 2011

In this session Citation tracking - what it is and why its important Finding out who’s citing you using: Web of Science Scopus Google Scholar. Creating citation alerts Next session WISER Bibliometrics II: The Black Art of Citation Ranking - more on measuring research impact

} Papers that share one or more citation in common - related Later papers that cite “your” paper { } Earlier papers referred to in “your” paper 2007

Why bother Trace the progress of research backwards, forwards and sideways Identify research papers in your field / stay ahead of competitors Assess the impact of your research – grants / jobs

Web of Science Science Citation Index Expanded (SCI) present Social Sciences Citation Index (SSCI) present Arts & Humanities Citation Index (A&HCI) present Conference Proceedings Citation Index- Science (CPCI-S) present Coverage: thousands of journals, conference papers, review papers, notes of meetings, letters, book reviews, art exhibits, poetry…but not books (yet!)

Search example Bartsch, R.A. & Cobern, K.M. 2003, "Effectiveness of PowerPoint presentations in lectures", Computers & Education, vol. 41, no. 1, pp. 77. Effectiveness of PowerPoint presentations in lectures Bartsch, RA & Cobern, KM Source: COMPUTERS & EDUCATION Volume: 41 Issue: 1 Pages: Published: AUG 2003 Cited references Times cited

General v Cited Reference General quick and easy but may be incomplete can also search for book reviews Cited Reference search Thorough – picks up variant citations Includes books (cited by papers on WOS) Includes publications that pre date the citation indexes (cited by WOS)

WoS: Book Citation Index Coming soon…second quarter of 2011 Initially 25,000 book titles Scholarly titles containing original research (not text books etc) back to 2005 for Sciences back to 2003 for Social Sciences / Humanities Includes references, footnotes, bibliographies

Cited references in Scopus Huge bibliographic database covering 18,000 scholarly journals & conference proceedings in Science, Medicine, Social sciences & Humanities “View references” displays the article’s bibliography. “Citations” column indicates times the article was cited by other articles in Scopus since 1996.

Citations column

NB ‘since 1996’

Cited references in Google Scholar References include ‘cited by’ data based on articles known to Google Scholar Entries ranked by number of cites Picks up citations in journals not covered by WoS or Scopus (especially non-English language), plus conferences, books, dissertations/theses, unpublished items such as Powerpoint shows etc… Not possible to sort, save sets or analyse

How did they compare? In October 2010: Web of Science 42 citing articles; 19 unique to WoS Scopus 45 citing articles; 10 unique to Scopus Google Scholar 117 citations; 79 unique But beware of phantom citations 19 references in common across the 3 databases.

Other databases Citing articles are becoming a feature in many databases Historical Abstracts Medline, Embase, PsycInfo, BIOSIS Previews …and other life science databases on the Ovid platform JSTOR Full-text databases such as ScienceDirect, Wiley Online Library Number of times it has been cited in that database. Look for links such as “Cited by”, “Citing articles”

Quality or quantity? Meho, L. I.; Yang, K. (2007). "Impact of Data Sources on Citation Counts and Rankings of LIS Faculty: Web of Science vs. Scopus and Google Scholar". Journal of the American Society for Information Science and Technology 58 (13): 2105–2125.Journal of the American Society for Information Science and Technology doi: /asi.20677doi /asi.20677

Meho and Yang’s study found that: Google Scholar identified more citations than Web of Science and Scopus combined but most of those extra ones were from low-impact journals or conference proceedings.

Coverage compared Web of Science - strong coverage of journal publications, but poor coverage of high impact conferences. Scopus - better coverage of conferences, but poor coverage of publications prior to Google Scholar - best coverage of conferences and most journals (though not all), but like Scopus has limited coverage of pre-1990 publications.

Bibliometrics If you want to count or analyse your citations or ‘impact’, the tools to use are Web of Science Scopus
