  1. 1. How to Search Literature In Citation Databases (Web of Science , SCOPUS) Journal Paper & Thesis Writing Workshop, PGSS FS 2011SITI NISRIN MOHD ANIS,RESEARCH SUPPORT DEPT, PERPUSTAKAAN SULTANAH ZANARIAH,UTM, SKUDAI , JOHOR2 November 2011Blog : |
  2. 2. How to access?
  3. 3. OR
  4. 4. Steps:PSZ portal Databaseschoose WOS or SCOPUS login through EZProxy ( your
  6. 6. WOS : By Topic / Subjects
  7. 7. SCOPUS : by Topic / Subjects
  8. 8. Web of Science SCOPUS Refine OptionWeb of Science Refine Option SCOPUS Refine Option
  9. 9. Other output categories in SCOPUS• More – The reference icon indicates that a document is not available in the Scopus database, but is extracted from references list in Scopus documents• Web - Web results by SCIRUS• Patents
  10. 10. To search for list of Impact Factor ONLY available in WOS via Journal Citation Reports (JCR)
  11. 11. H-index• to measure both the productivity and impact of the published work of a scientist or scholar.• The index is based on the set of the scientists most cited papers and the number of citations that they have received in other peoples publications.• The index can also be applied to the productivity and impact of a group of scientists, such as a department or university or country.• The index was suggested by Jorge E. Hirsch, a physicist at UCSD, as a tool for determining theoretical physicists relative quality[1] is sometimes called the Hirsch index or Hirsch number.
  12. 12. H-index is available in WOS & SCOPUS• Example, Prof Norsarahaida Amin• List the author abbrevations: – Amin, N – Amin, Norsarahaida – Amin, Norsarahaida S
  13. 13. In WOS , use Author Finder
  14. 14. H-index for Prof Amin, NCitation count for Prof Amin, N
  15. 15. In SCOPUS, use Author Search + Affiliation
  16. 16. H-Index : WOS vs SCOPUS• Example :Prof Norsarahaida Amin  H-index WOS : 11 || Citation WOS : 372  H-index SCOPUS : 12 || Citation SCOPUS : 455• Q: Usually, h-index / citation in SCOPUS will be slightly higher or higher than h-index in WOS, why? A: Both databases covers different regions (WOS more to US , SCOPUS more to European & Asian )
  17. 17. What is citation?• citation is a reference to a published or unpublished source• The usage : to attribute prior or unoriginal work and ideas to the correct sources to allow the reader to determine independently whether the referenced material supports the authors argument in the claimed way (wikipedia)
  18. 18. Citation Calculation• Differs between WOS, SCOPUS & Google Scholars• WOS provides more details calculation• Publish or Perish (PoP) Software helps to calculate citation of Google Scholars• Usually, citation counts in SCOPUS is higher than WOS• Sometimes, Google Scholars citation counts is higher than both prominent citation databases• Nevertheless, WOS is the citation pioneer & their data is trustworthy
  19. 19. Example of citation count (SCOPUS): by topic
  20. 20. Sort by:
  21. 21. Example of citation count (Web of Science) : by Topic
  23. 23. About Web of Science• The Institute for Scientific Information (ISI) was founded by Eugene Garfield in 1960.• It was acquired by Thomson Scientific & Healthcare in 1992, became known as Thomson ISI• and now is part of the Healthcare & Science business of the multi-billion dollar Thomson Reuters Corporation.• Source :
  24. 24. About Web of Science• ISI offered bibliographic database services• Its speciality: citation indexing & analysis• It maintains citation databases [print-based indexing services: Science Citation Index (SCI), Social Sciences Citation Index (SSCI), Arts and Humanities Citation Index (AHCI).• All of these are available via ISIs Web of Knowledge database service.
  25. 25. What is Web of Knowledge ?• Web of Knowledge is a research platform• it brings together many different types of content for searching [ Journal articles, patents, websites, conference proceedings, Open Access material ]• all can be accessed through one interface
  26. 26. Web of Science VS Web of Knowledge • Web of Science® can be found within Web of Knowledge • This resource offers access to journal articles in the sciences, social sciences and arts and humanities. • Contains over 100 years of valuable research, fully indexed and cross-searchable.
  27. 27. Web of Science Content1. Science Citation Index Expanded (SCI-EXPANDED) -- 1990-present2. Social Sciences Citation Index (SSCI) --1990-present3. Arts & Humanities Citation Index (A&HCI) --1990- present4. Conference Proceedings Citation Index- Science (CPCI- S) --2004-present5. Conference Proceedings Citation Index- Social Science & Humanities (CPCI-SSH) --2004-present
  28. 28. Useful Links:• Link to List of Science Citation Index Journal : – bin/jrnlst/jloptions.cgi?PC=K• Link to List of Art & Humanities Citation Index Journal – bin/jrnlst/jloptions.cgi?PC=H
  29. 29. Useful Links: Useful Links:• Link to List of Social Science Citation Index Journal• bin/jrnlst/jloptions.cgi?PC=J•• Link to Conference Proceedings Citation Index• s/science/science_products/a- z/conf_proceedings_citation_index
  30. 30. In SCOPUS You can start your search by:• Document Search – Article Title, Abstracts , Keywords – Source Title ( journal / conf. titles) – Authors• Authors Search• Affiliation Search (by authors institution)• Advanced Search (with OPERATORS & specialized codes)
  31. 31. Define Impact Factor• A citation metric• the impact factor of a journal is the average number of citations received per paper published in that journal• The journal must be published in 2 consecutive years, so the IF can be calculated in the 3rd year
  32. 32. Example of IF calculation• In 2008, a journal has an impact factor of 3.0• it means papers published in 2006 and 2007 received 3 citations each on average. Calculation: 2008 impact factor = A/B
  33. 33. 2008 impact factor = A/BA = the number of times articles published in 2006 and 2007 were cited by indexed journals during 2008B = the total number of "citable items" published by that journal in 2006 and 2007. ("Citable items" are usually articles, reviews, proceedings, or notes; not editorials or Letters-to-the-Editor.)
  34. 34. Reminder!• 2008 impact factors are actually published in 2009• it cannot be calculated until all of the 2008 publications have been processed by the indexing agency
  35. 35. From UTM Pub List 2010
  36. 36. Related to IF : Immediacy Index• immediacy index is a measurement of the skewness of the curve• Its calculate of how quickly items in that journal get cited upon publication
  37. 37. Related to IF : Cited-half life• is a measure of the rate of decline of the citation curve• Its calculate of how long articles in a journal continue to be cited after publication
  38. 38. Related to IF : Citing-half life• the median age of articles cited by the journal in the JCR year.• For example, in JCR 2003, the journal Food Biotechnology has a citing half-life of 9.0. That means that 50% of all articles cited by articles in Food Biotechnology in 2003 were published between 1995 and 2003 (inclusive).
  39. 39. Related to IF : Citing-half life• Only journals that publish 100 or more cited references have a citing half-life• Cited-only journals do not have a citing half- life
  40. 40. SUMMARY OF CITATION MEASUREMENT• the journal impact factor, the ratio of the number of citations to the previous 2 years of the journal divided by the number of articles in those years — this is essentially the average number of recent citations per article• the journal immediacy index, the number of citations that year to articles published the same year• the journal citing half life, the median age of the articles that were cited by the articles published in the journal that year• the journal cited half life, the median age of the articles in the journal that were cited by other journals during the year
  41. 41. Another citation metric : Eigenfactor• a measure of journal influence• Unlike traditional metrics [Impact Factor] the Eigenfactor method weights journal citations by the influence of the citing journals.• As a result, a journal is influential if it is cited by other influential journals.
  42. 42. Other definition of Eigenfactor Score• The Eigenfactor Score calculation is based on the number of times articles from the journal published in the past five years have been cited in the JCR year• It also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser cited journals.• References from one article in a journal to another article from the same journal are removed, so that Eigenfactor Scores are not influenced by journal self-citation
  43. 43. Related to Eigenscore : Article Influence Scoredetermines the average influence of ajournals articles over the first five yearsafter publication.calculated by dividing a journal’sEigenfactor Score by the number ofarticles in the journal, normalized as afraction of all articles in all publications.
  44. 44. The mean of Article Influence Score is 1.00 • A score greater than 1.00 indicates that each article in the journal has above- average influence. •A score less than 1.00 indicates that each article in the journal has below-average influence.
  45. 45. Journal Citation Report (JCR)• An annual publication by the Healthcare & Science division of Thomson Reuters• It has been integrated with the Web of Knowledge, by Thomson Reuters• Can be accessed from the Web of Science to JCR Web
  46. 46. About H-index : the formula‘ A scientist has index h if h of [his/her] Np papers have at least h citations each, and the other (Np − h) papers have at most h citations each’Example, Prof Norsarahaida Amin has h-index of 12, total pub of 49 articlesfrom 49 articles she published in SCOPUS, at least 12 of the articles is cited 12 times
  47. 47. Other citation analysis tool : Harzing Publish or Perish The founder : Prof Anne-Will Harzing
  48. 48. Harzing’s software (free download)
  50. 50. Example of HarzingPublish or Perish
  51. 51. How to search for subject not cover in Web of Science ?Example : Thermofluids• Step 1 : identify terms and keywords,synonyms and related terms for the said topic• Step 2: Use WOS to search for relatedjournals
  52. 52. Search by Subject / Topic
  53. 53. Output display  refine by Subject Areas
  54. 54. In refine by Subject Areas, click at ‘more options/values  choose most suitable subject  then analyze results
  55. 55. In Rank the records, choose Source Title ( journal title)
  57. 57. NoteQ1 : Does Proceeding has impact factor?A1 : Usually, NO, example,“AMS2010: Asia Modelling Symposium 2010 - 4th International Conference on Mathematical Modelling and Computer Simulation”  no impact factorQ2: Journal title exist, but no impact factor ?A2: The journal is not publish in 3 consecutive years
  58. 58. Other Info• ISI publishes Science Watch, a newsletter which identifies every two months one paper published in the previous two years as a Fast breaking paper in each of 22 broad fields of science, such as Mathematics (including Statistics), Engineering, Biology, Chemistry, and Physics
  59. 59. “ the life of a professor is great – it’s either publish or PARIS!!”????
