Scientometrics (bibliometrics) • Scientometrics (bibliometrics) - The measurement of scientific output activity through statistics on academic publications • The scope of bibliometrics includes: “all quantitative aspects and models of science communication, storage, dissemination and retrieval of scientific information”.
تعريف علمسنجی • آن دسته از روشهای کمّی را که به تحليل علم بعنوان يک فرآيند اطلاعاتی تأکيد دارند ”علم سنجی“ مینامند. • ”علم سنجی“ به تعبيری ساده تر عبارت است از دانش اندازهگير علم.
Scientometrics informetrics bibliometrics scientometrics cybermetrics webometrics
Informetrics • broader than bibliometrics and scientometrics • Informetrics examines patterns that show up not only in publications but also in many aspects of life as long as the patterns deal with information. e.g. Willis Law deals with the relationships between the age of a group of the animal and plant species and the habitation of these species • its concepts, formulas applicable to publication patterns.
Bibliometric dataused for.. • Scientific output evaluation • Impact • Citations • History of science • Publication strategies • Science policy; resource allocation • Collection management • Sociology of science • Information organization • Information management & utilization

نمونه ايميل ارسالی برای مکاتبه برای ادغام تنوعهای نوشتاری اسامی افراد در Scopus آدرس ارسال ايميل: ScopusAuthorFeedback@elsevier.com Dear Colleague This is a request to merge the papers of an author in our university which his papers divided in two author affiliation format. His name is Reza Madani & unfortunately his total papers are divided mainly in his 2 separate author identities as Author ID's 36601112600 & 9246620000. Of course all the 2 authors-affiliation listed below, are really his own papers. As these two Author ID really belong to one person & he is Reza Madani, I appreciate you if you merge these 2 together in one Author ID. Your action & attention is appreciated. Best Regards Payam Kabiri

Other Tools Available • Other bibliometric indicators: • Journal Citation Reports (JCR) • Other indicators databases (national, essential, university, institutional) • ISIHighlyCited.com
Scopus • Positioning itself as an alternative to ISI • More journals from smaller publishers and open access (+18,000 journals; +1000 conf proceedings) • Source data back to 1960. • Excellent for physical and biological sciences; poor for social sciences; does not cover humanities or arts. • Better international coverage (60% of titles are non-US) • Back to 1996 ! (e.g. citation data for the last decade only) • Easy to use in searching for source publications; clumsy in searching cited publications. • Citation tracker works up to 1000 records only.
Google Scholar • Better coverage for all citations as it retrieve web ! • More coverage of references also gray literature ! • Coverage and scope? • Inclusion criteria? • Very limited search options • No separate cited author search • Back to 1990 NOT more ! • Free!
Web of Science(Now Thomson Reuter ISI) • Covers around 10,000 journal titles and 110,000 conference proceedings & alos 200 book series divided between SCI, SSCI and A&HCI. • Over 40 million records! • Electronic back files available to 1900 for SCI and mid- 50s for SSCI and mid-70s for A&HCI. • Very good coverage of sciences; patchy on “softer” sciences, social sciences and arts and humanities. • Full coverage of citations.

Web of Science If a journal is in Web of Science, it means it should have Impact Factor & vice versa. Don’t confuse Web of Sciences Journals with ISI Master list Journals ! Web of Science indexed about 10,000 Journals while ISI Master List 14,000 Journals.
The Journal Impact Factor The Journal Impact Factor is calculated for those journals only which are indexed & included in Web of Sciences Databases, NOT more ! The database which contain the Journal Impact Factors is Journal Citation Report abbreviated JCR.
What is Journal Impact Factor? The average citation frequency for articles published in a journal, or how many times, on average, during the study year the articles that appeared in the 2 preceding years of that journal received citations in other (ISI) indexed journals only.
Impact Factor Calculation • Citations in the current JCR year to articles published in the previous two years divided by the number of articles published in the previous two years. Citations in 2007 to articles published in 2005 + 2006 IF= Total 2005 + 2006 Papers
Citation Source paper – published in 2007 Cited reference – published in 2006 or 2005 Immediacy Index 2007 2006 2005 All Previous Years Impact Factor Cited ½ Life Cited reference – published in 2007
How to Find Impact Factors? • Directly from Journal Citation Report Database through ISI. • Using the Excel & PDF Datasheets, prepared especially for this matter. • www.hbi.ir • www.sid.ir
The h-index شاخص جديدي از شاخصهاي علمسنجي است. اين شاخص در سال 2005 ميلادي توسط Jorge Hirsch در دانشگاه کاليفرنيا ابداع شد. اين شاخص در واقع با هدف ارزيابي کيفي اثر و ارزيابي کمي برونداد پژوهشي محققين ابداع شده است.
The h-index مفهوم H-Index عبارت است از تعداد مقالات نويسنده که تعداد ارجاعات برابر با h و يا کمتر از آن دارند. مثلا چنانچه H-Index محققي 5 باشد، مفهوم آن اين است که اين محقق 5 مقاله منتشر شده دارد که هرکدام حداقل 5 استناد يا Citation دارند. به عبارت ديگر مفهوم آن اين است که ساير مقالات اين محقق کمتر از 5 استناد دارند. امروزه اين شاخص معادل Impact Factor براي محققين محسوب ميشود.
The H-index: a definition • ‘The H-index is the highest number of papers a scientist has that have at least that number of citations.’ Nature (2005)
H-index was born ! • We need an Index both to include quantity & also quality of an authors' paper • Productivity • Impact • Not affected by “big hits” • Not affected by “noise”
How to calculate the h-index? • You can calculate the h-index through the following citation databases: • Web of Science • Scopus • Google Scholar • (http://scholar.google.com)
h-index Calculation through Google Scholar To calculate h-index thriough Google Scholar, you shodul use the 3rd parties services. Some softwares has been developed for this matter, like: Publish or Perish
Publish or Perish Software You can download from: http://www.harzing.com/ It’s a free software which can be dwonloaded directlfy at: http://www.harzing.com/pop.htm
