• Google Scholar’s simplicity may actually be a boon • Some institutions cannot afford Web of Science • Google Scholar offers some non-periodical sources • Google-Scholar is much more clumsy to use, if you’re going to collect (download & analyze) citation data • Google-Scholar is valuable for international and different formats • Don’t trust Google Scholar to sort properly, detect duplicates, etc. • Google scholar looks at nonscholarly sources, and this can be useful, or a distraction • Accuracy of Google Scholar is lower… • Web of Science is criticized for being American-based, Englishlanguage • Google Scholar is better at finding citing sources in nonEnglish literature from Africa, Asia and Central and South America. • All three tools yielded unique material • There’s no simple solution 1994 1999 2000 A certain published paper, 2004 2002 2003 … Time … 2005 2008 2011 2012 ROBIN LARSON ELLIOTT FISHER Robin & Elliott’s paper, 2004 … Time … 18 papers, from 2005 to 2011 40 papers, from 1976 to 2003 Robin & Elliott’s paper, 2004 … Time … 18 papers, from 2005 to 2011 40 papers, from 1976 to 2003 Robin & Elliott’s paper, 2004 … Time … 18 papers, from 2005 to 2011 Web of Knowledge Web of Science Inspec MEDLINE Journal Citation Reports Web of Knowledge Web of Science • Science Citation Index (1899-present) • Social Sciences Citation Index (1956present) • Arts & Humanities Citation Index (1975present) Impact Factor How many times were these articles cited this year # of articles published in the Journal in previous two years How many times were these articles cited this year # of articles published in the Journal in previous two years Impact Factor How many times were these articles cited this year # of articles published in the Journal in previous two years Amim, M and Mabe, M (2007) Impact factors: use and abuse Amim, M and Mabe, M (2007) Impact factors: use and abuse Amim, M and Mabe, M (2007) Impact factors: use and abuse Amim, M and Mabe, M (2007) Impact factors: use and abuse Eigenfactor Score • Times articles from a journal have been cited over past 5 years – Gives more weight to highly cited journals – Journal self citations are removed – The scores of all JCR journals add up to be 100 Article Influence Score • A weighted 5 year impact factor – Normalized so the average influence score = 1 See Eigenfactor.org for more information
