Introduction

Tamil Nadu is one of India’s 28 states. Chennai (formerly known as Madras) is its capital and largest city. Located in the southernmost part of the Indian subcontinent, Tamil Nadu is bordered by the union territories of Puducherry and Kerala, Karnataka, and Andhra Pradesh, South Indian states. It is bordered on the north by the Western Ghats, the Nilgiri Mountains, the Meghamalai Hills, and on the west by Kerala, on the east by the Bay of Bengal, on the southeast by the Gulf of Mannar, and on the south by the Indian Ocean. The state shares a sea border with the Sri Lankan government. In Tamil Nadu, there are 22 state universities and 29 Deemed Universities operating, which include the disciplines of arts and science, engineering, agriculture and medicine. [2]. University Grant Commission (UGC) is the major funding sponsor in Tamil Nadu publications UGC and other statutory regulatory bodies are responsible for the organization and maintenance of standards in universities and colleges in Tamil Nadu.

Indian Institute of Technology Madras (IITM) got third rank and Anna University got thirteen rank in all over the India during the year of 2019 [3] and National Institute Ranking Framework [4] (NIRF) ranking, the Indian Institute of Technology Madras bagged the 1st ranks and Anna University got 13th rank among the overall institutions in India during the year of 2019 The first university was established in 1857 at Chennai (Madras) University of Madras, followed in 1929 by Annamalai University Annamalai Nagar. These two universities are our nation’s pre-independence universities [5]. In India, one of the most highly ranked institution available state was tamilnadu, by holding IITs, IIMs and leading medical and technical universities. Analyzing the scholarly research output of this Indian state will give an overview of the Indian research growth, further, to identify the gap in the research in different disciplines and research growth this study will give a greater benefit to all the researchers.

Review of Literature

Mohamed Idhris, Manuelraj Peter, Abdurahiman Pattukuthu and Spurgeon Anandraj Samuel [7], the study reveals a gradual increase in work on LUPUS between 2010 and 2017. Highest number of publications related to the year 2016. During 2010-2017, the United States is the top contributor. PETRI M is the lead author with 394 papers comprising 1,017% of the overall publications. Siwach AK et al. [8] research explores Maharshi Dayanand University, Rohtak’s research contributions in terms of publishing output over the period 2000-2013 as reflected in the Scopus database. The research evaluates the year - to-year efficacy of research, its effects on citations, national and international partnerships, top collaborative institutions, subject-matter distribution of articles, journals used for correspondence, most popular journals for publishing, most prolific authors, number of citations earned and top-quoted University papers during the study period.

N Geetha et al. [9] analyzed that her paper on Research Output of Anna University: A Bibliometric Study Based on Scopus Database stated her study shows that there is substantial research output and a steady increase in publications among Anna University academics and the dominance of collaborative work between Anna University. Venkatakrishnan CJ [10] Analysis of the growth trend was carried out and predictions are presented. Prosthodontist exhibited a tendency to publish case reports in general dental journals in international newspapers. Poorni S, et al. [11] analyzed that Most of the 33 papers have been published in the Indian Journal of Dental Research and 25 in the Conservative Dentistry Review. Of these papers, 66 are based on the authors ‘ original research. Kumaragurupari R, et al. [12] revealed that research quality, as reflected in both the number of publications in peer-reviewed journals and those journals ‘ qualitative indicators, improved during the duration of this study.

Methodology

The chosen data were downloaded from Scopus database. The following search terms have been used to retrieve the records from database “AFFILCITY (Tamilnadu) OR AFFILCITY(Tamilnadu) OR AFFILCITY(Chennai) OR AFFILCITY(Vellore) OR AFFILCITY(Tiruvannamalai) OR AFFILCITY(Cuddalore) OR AFFILCITY(Villuppuram) OR AFFILCITY(Kancheepuram) OR AFFILCITY(Tiruvallur) OR AFFILCITY(Kallakurich) OR AFFILCITY(Chengalpattu) OR AFFILCITY(Tirupattur) OR AFFILCITY(Ranipettai) OR AFFILCITY( Coimbatore) OR AFFILCITY(Nilgiris) OR AFFILCITY(Salem AND india) OR AFFILCITY(Dharmapuri) OR AFFILCITY(Erode) OR AFFILCITY(Dindigul) OR AFFILCITY(Karur) OR AFFILCITY(Namakkal) OR AFFILCITY(Krishnagiri) OR AFFILCITY(Tirupur) OR AFFILCITY(Thanjavur) OR AFFILCITY(Tiruchirappalli) OR AFFILCITY( Trichy) OR AFFILCITY(Pudukkottai) OR AFFILCITY(Nagapattinam) OR AFFILCITY(Tiruvarur) OR AFFILCITY(Perambalur) OR AFFILCITY(Ariyalur) OR AFFILCITY(Kanyakumari) OR AFFILCITY( Madurai) OR AFFILCITY(Ramanathapuram) OR AFFILCITY( Tirunelveli) OR AFFILCITY(Virudhunagar) OR AFFILCITY(Sivagangai) OR AFFILCITY(Thoothukudi) OR AFFILCITY(Theni) OR AFFILCITY(Tenkasi)” from 2009 to 2018. No journal or types of article restrictions have been established. All the publications that were displayed were taken into the analysis. In Excel, a data sheet was prepared to record the information and then the data was entered from the paper itself manually.

Table 1 shows the yearly publication of articles published by Tamil Nadu State based on Scopus results. When reviewing the last ten years of publishing results, it is observed that (14.35%) of articles n=26947 published in 2018 and the remaining 85 percent of articles published over a 9-year period. While 2015 has the second highest number of articles n=25899, (13.79 %), the lowest number of articles published in 2009 was n=8188 (4.36%). On an average, n=18781 articles were published per year. After 2014 research publication increased very rapid, and last five years contributed 68.88% of the research output. From Figure 1, we can see an upward trend in Tamil Nadu’s research output regarding the number of publications from the Scopus list (Tables 1 & 2) (Figure 1) [13,14].

Table 3 shows the list of Journals ranked. The most productive journal is the International Journal of Applied Engineering Research with n=5949 articles, followed with n=2155 articles by the Indian Journal of Science and Technology, some of the journals cite score and citations data are not available in the Scopus database. The Journal of Clinical and Diagnostic Research published by (JCDR Research and Publications (Pvt) Limited) n=1053 got least number of publications among top 15 journals list (Table 4) (Figure 2). Another research we performed was to determine the top 15 keywords used in this Tamil Nadu publication. During the last decades from the n=187817 documents found. The top 15 keywords with high frequency of occurrence are “human” utilized n=26525 (14.12%) items, followed by “Controlled Study” n=17223 (9.17%) and “Nonhuman” n=15693(8.36%) items. It was identified that the top listed keywords are mostly from medical and Science background (Table 5) (Figure 3) [15].

Conclusion

The study was conducted based on Scopus database during 2009-2018 of Tamil Nadu. Publication growth in Tamil Nadu is expanding rapidly in recent years. UGC is the major funding sponsor in Tamil Nadu publications and UGC funded publication count is increased year by year nevertheless after between 2015 to 2018 publication count is decreased it shows that lack of publication awareness among the researchers. The Scopus database covered only standard publications that is one of the reasons for it. Most of the top-ranking authors are working in the non-governmental organizations. Publication count has increased to force Nongovernmental organization authors to work under them. In recent years, the number of publication count is increased year by year.
