To illustrate the method, literature on the field of tribology covered in Science Citation Index Expanded of Web of Science published during 2001 – 2010 is used. As tribology is highly multidisciplinary in nature, which can be demonstrated by the proposed method, the method can be used for other subject disciplines.

Literature on tribology research was selected as the sample and Science Citation Index Expanded of WOS is used to retrieve the related bibliographic records. The studied parameters are: yearly share, document type and language, number of references, number of authors, share of single authored papers and average number of keywords. The results show that there is a significant difference in characteristics between cited and uncited papers.

India’s global publication share, annual output, and its citation impact of Indian contribution, partner countries, leading contributors, leading institutes, and highly cited papers were analyzed. Additionally, a cloud technique is used to map frequently used single words in titles. It is observed that India ranks in the 7th position with a global publication share of 3.83% and an annual average growth rate of 25.58% during the period 2001–2012. The citation impact of India’s contribution is 6.05 which decreased from 12.74 during 2001–2006 to 4.62 during 2007-2012. 17.4% of India’s total research output was published with international collaboration.

SCOPUS database has been used to retrieve the bibliographic records for the study period. The authors analyzed the document type, authorship and publication pattern of tribology research output among the BRIC countries. Statistical methods and scientometric tools such as, growth rate, collaboration co-efficient, co-authorship index and transformative activity index are used for the study. The quality and impact of tribology research output among the BRIC countries have been analyzed with citations per paper and relative citation impact. Further highly productive journals have been mapped and ranked based on h-index.

The SCOPUS database was used to retrieve records related to the nanotribology research for the period 1996–2010. Publications were counted on a fractional basis. The level of collaboration and its citation impact were examined. The performance of the most productive countries, institutes and most preferred journals is assessed. Various visualization tools such as the Sci2 tool and Ucinet were employed. The USA ranked top in terms of number of publications, citations per paper and h-index, while Switzerland published a higher percentage of international collaborative papers. The most productive institution was Tsinghua University followed by Ohio State University and Lanzhou Institute of Chemical Physics, CAS. The most preferred journals were Tribology Letters, Wear and Journal of Japanese Society of Tribologists. The result of author keywords analysis reveals that Molecular Dynamics, MEMS, Hard Disk and Diamond like Carbon are major research topics.
