Bibliometrics toolkit Website: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Further info: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Scopus Scopus was launched by Elsevier in 2004 The suite of citation analysis tools provided within Scopus is called Research Performance Management – RPM Scopus offers Live Chat to support users of the product There are over 18,000 journal titles indexed in the product Key facts The database contains over 30 million citations Citations are only indexed from publications from 1996 which is a disadvantage in comparison to the ISI suite of products The main calculations such as author h-index are also only worked out cited material from 1996 on, cites to earlier items are discarded before calculating There are 18,000+ peer reviewed titles in Scopus - a lot more than other data sources and this makes the product better for some fields such as Engineering The range of materials included is said to be better for humanities and in 2009 a significant increase in such titles took place There is more European content and it does include more languages other than English than ISI – 60% of coverage is outside the USA Open Access titles, proceedings, web pages, patents, book series are all included Main alternative citation data sources for comparison Thomson Reuters ISI product suite including Web of Science and Journal Citation Reports Google Scholar with the Publish or Perish software application Subject specialist databases with citation information, available in some fields - Life Sciences get better coveriage in Medline for example, Computer Science in CiteseerX or ACM Authors Journals Articles Citation Overview Use the tools provided to select one author or a group of authors – you can filter by affiliation, country and subject area and pick variant forms of an author name. This is a strong feature of the product, providing assistance in isolating a set of the correct research outputs, particularly where names are common. Then click on View Citation Overview to create a sumary of the selected author or group of authors. The Citation Overview shows: The number of documents cited in any year range current The pattern of citation by year and total cites Self-citations can be removed if wished The citing documents can be viewed – however unlike ISI there is no analysis offered by geography, discipline or document type The author(s) h-index is provided, based on publications 1996 onwards. For example, there may be 16 documents found that are cited but the h-index is calculated only on the 12 published from 1996 Graphs are provided for the h-index, publication count and citation count Journal Analyzer Pick the Analytics tab to use Journal Analyzer to select a journal title or build up a group of titles. The analysis includes both graphs and tabular displays of: Number of articles published per year in the title(s) from 1996 to date Number of citations in total to the articles per year Number of articles per year not cited, as a percentage Trend line showing the average number of citations per paper every year Two key metrics are provided: SJR which weights according to impact of the citing journal and SNIP which is a complex attempt to normalise based on citing depth and speed of citation in the discipline, plus allowing for the amount of material in the source dataset. SNIP is designed to allow cross- discipline comparison, normally not possibly with these metrics Selecting a number of titles allows you to see the relative performance of each, best with the graph display Unlike JCR, this analyser does not provide ranked lists of journals for your field. However, the free SCImago website uses the Scopus data set to provide this type of ranked listing comparable to the ISI JCR product Each document returned in a search has an indication of the number of citations to it found in Scopus The citing documents can be viewed in turn as a list if desired. Or, for any particular article in the set, citation tracker can be used to get a more detailed analysis of the citations by year for that item - as well as viewing the citing articles.
