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.

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.

Web of Science “Web of Science” is the database name provided by “Institute of Scientific Information” famous in our country as “ISI”. The company name now is Thomson Reuters, No ISI available there. The Web of Knowledge is a portal in which you can search multiple ISI databases including Medline, Web of Science, Current Content, Biological Abstract & others.

Scopus Positioning itself as an alternative to ISI More journals from smaller publishers and open access (+19,500 journals; conf proceedings) Source data back to 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 11,000 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 11,000 Journals while ISI Master List 15,000 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 IF= Total Papers

Source paper – published in 2007 Cited reference – published in 2007 Cited reference – published in 2006 or 2005 Citation Immediacy Index Impact Factor All Previous Years Cited ½ Life

2010 Impact Factors

2011 Impact Factors

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. امروزه اين شاخص معادل Impact Factor براي محققين محسوب مي‌شود. The h-index

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”

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 Concept through its Graph

The h - Graph

How to calculate the h-index? You can calculate the h-index through the following citation databases: Web of Science Scopus Google Scholar  (

بزرگترين شاخص h در دنيا مربوط به حوزه علوم زيستی برابر با 197 و بزرگترين شاخص h محققان ايران جناب آقای دکتر شمسی پور استاد شيمی دانشگاه رازی کرمانشاه با عدد h برابر 47 می‌باشد.* * مربوط است به سال 1390 The highest h-index in the World & Iran
