(mandhra.m@gmail.com) ABSTRACT This study is a scientometric analysis of the research publication output of Thiagarajar College of Engineering (TCE), Madurai. Data for the study have been collected from the Scopus database from the beginning of 1972 to Among the 1497 papers published in the span of 43 years, highest number of 259 papers can be traced in Among the total output, 1231 papers (82.23%) were published during the last seven years ie. from 2008 to Dr.R.Rajaram and Dr.R.Sukanesh are the most productive authors with 60 papers each. Journal is the most sought form of publication with 977 papers. H Index of TCE is 34. This study reveals that TCE has notably contributed to the research in science, engineering and technology and the publications of faculty have increased significantly during the last seven years. Keywords: Research publication, Publication output, Thiagarajar College of Engineering, TCE, Bibliometrics, Scientometrics, Scopus. INTRODUCTION Scientometrics, a term invented by Vasily Nalimov is the study of measuring and analysing the published literature. Scientific output in the form of publications can be measured by using bibliometric / scientometric techniques like number of publications based on author, institution, country, year, type, subject and citation etc 1. In practice, scientometrics is often done using bibliometrics which is a measurement of the impact of (scientific) publications. In this study, the author has made an attempt to study the research output of the faculty of Thiagarajar College of Engineering (TCE), Madurai by using bibliometric / scientometric techniques. THIAGARAJAR COLLEGE OF ENGINEERING Thiagarajar College of Engineering (TCE), Madurai, an ISO 9001:2008 certified institution affiliated to Anna University is one among the several educational and philanthropic institutions founded by Philanthropist and Industrialist Late. Shri. Karumuttu Thiagarajan Chettiar. It was established in the year TCE is funded by central & state governments and management. The courses offered in TCE are approved by the AICTE. It was granted Autonomy in TCE has also been accredited by the NBA. TCE offers 7 UG programmes, 14 PG programmes and doctoral programmes in engineering, science and architecture 2. REVIEW OF LITERATURE Maharana and Sethi (2013) 3 have studied the publication output of publication in Sambalpur University during 2007 and 2011 and reported that Chemistry is the most sought area of research and publication of faculty followed by Physics and Plant Science etc. Mandhirasalam (2014) 4 analysed the publication output of Coimbatore Institute of Page491

3 Technology (CIT) and reported that significant contribution (86.38%) in the total publication output (639 papers) exits from the year 2006 onwards. Mandhirasalam (2015) 5 analysed the publication output of PSG College of Technology (PSGCT) and reported that 2357 papers were published in the span of 44 years ie. from 1971 to 2014 and 2112 papers (89.6%) were published during the last ten years. OBJECTIVES The objectives of the study include: To find out the year-wise research publication output of TCE To know the types of publication To determine the most productive authors and authorship pattern To identify the research collaboration of TCE with other countries and institutions To identify the journal-wise output To examine the major areas and subjects of publication output To analyse the citation receipt of publications of TCE. METHODOLOGY Data on the research publication output of TCE were collected from the Scopus 6 database including all the years (papers), ie. from 1972 to Scopus, a product of Elsevier is the largest abstract and citation database of peer-reviewed literature: scientific journals, books and conference proceedings. It gives a comprehensive overview of the world's research output in the fields of science, technology, medicine, social sciences, and arts and humanities. It offers the number of citations has received by each published document. It has a facility to calculate h-index of authors and institutions 7. The keywords Thiagarajar College of Engineering were used in the document search option and selecting the address category. Query: (AFFILORG(Thiagarajar College of Engineering) AND PUBYEAR < 2015). 8 DATA ANALYSIS AND RESULTS Table 1: Year-wise Output of Publications Year Papers Percent to Total Table 1 shows significant increase in publication started from 2008 with 113 publications and 2014 is the most productive year with 259 (17.3%) publications followed by 2013 and 2011 with 224 (14.96%) and 202 (13.49%) publications respectively. The publications output of last seven years, ie. from 2008 to 2014 contributes 1231 (82.23%) publications among the total of 1497 in 43 years (1972 to 2014). Page492

They have also presented their papers in 404 (26.99%) conferences and contributed 516 papers ( 34.47%) in the proceedings. They have published 96 (6.41%) book series as well. Other types like books and trade publications are very less (20 with 1.34%).

Double authored papers ( 563 with 37.61%) are more among the collaborative papers followed by three (494 with 33%) and four (260 with 17.37%) authored papers. Only 27 papers (1.8%) were contributed by single authors. Degree of Collaboration of Publications The extent of collaboration can be measured with the help of multi-authored papers. Collaborative co-efficient is used to measure the collaborative research publications. Collaborative co-efficient is the ratio of the number of collaborative research publications during a particular period of time. The value of collaboration lays between 0 and 1 according to the formula of Subramanyam 9 that determine the degree of collaboration in a discipline. To examine the degree of collaboration of publications, the number of single authored and multi-authored publications is calculated using the Subramanyam formula: C=Nm/Nm+Ns C = Degree of Collaboration Nm = Number of multi-authored publications Ns = Number of single authored publications Hence C = 1470/ = Hence, it is found that the degree of collaboration of publications of TCE is Table 5: Country wise Collaboration (Top 5 Ranked Countries) Rank Country Papers 1 Malaysia 34 2 USA 24 3 Singapore 15 4 Taiwan 10 4 United Kingdom 10 5 Australia 9 Table 5 shows that the faculty of TCE collaborated with researchers of Malaysia and USA for 34 and 24 publications respectively. Researchers of Singapore worked with faculty of TCE for 15 publications. Authors of Taiwan and UK collaborated for 10 publications each. Authors from Australia collaborated for 9 papers.

9 4 papers have received more than 100 citations and 10 papers have received 50 to 99 citations. 775 (51.77%) papers have not received a single citation. Total citation receipt of 722 cited papers is Among them, 1381 (22.14%) citations were received in 2014 and 1136 (12.32%) in H Index of TCE is 34. This means 34 papers have been cited at least 34 times. CONCLUSION The quality of teaching and learning process of any institution can be measured on the basis of its R&D and publication output. The quality of R&D and publications can be measured through scientometric studies by means of quantitative (papers) and qualitative (citations) analysis. This study has been carried out by analyzing the quantity and quality of publication output of TCE to notify the faculty, scientists and scholars to know the research trend and the subject areas of research and help them to do further research in their field. The findings show that TCE has notably contributed to the research in the fields of science, engineering and technology. REFERENCE 1. Leydesdorff, L. & Milojevic, S. (2015). Scientometrics.
