Research Output from IISc during 1999-2020: Scientometrics Analysis Case Study

Over the past Seven decades the knowledge or web of science database maintaining the core collections of Science Citation Index Expanded, and past Conference Proceedings Citation IndexScience and past two decades SciELO Citation Index, Journal citation reports. This paper analyses a results of a scientometric analytical case study of the research activities of highly cited papers from 1999 to 2020. This paper study a growth of publications, citations, average citations per publication and Hindex of top scientists or researchers, at Indian Institute of Science, Bengaluru, India. Besides that, this paper presents a citation-based mapping of data on global scientific activities from Indian Institute of Science, Bengaluru, India research publications using Web of Science Database. Using different kind of scientometric approaches, such as a h-index and Global Citation Scores. Researchers have published 32191 publications during 19992020 and cited at least 5519 times by end of 2020 are analyzed. Authors have been able to place their papers in high impact journals such as Physics, Engineering, Chemistry, Materials Science, Science & Technology, Computer Science, Biochemistry Molecular Biology, Mechanics, Mathematics, Telecommunications, and Crystallography. The study discloses an output of Indian Institute of Science Research Publications has greatly increased over period.


Introduction
In the area of library and information science scientometrics is a branch. Scientometrics tools shall be used to measure and compare the scientific activities at various levels including distribution of publications such as year wise, document type-wise, subject wise, source/journal wise, countries-wise, authors wise and highly cited papers with citation map. It is concerned with a characteristics of science and scientific research and quantitative features.

About Indian institute of science
Indian Institute of Science, Bengaluru, is a forefront of research and education in a basic science subjects and engineering technology subjects. Today, Institute has a very high international reputation in the academic world, in view of the fact; it has expertise both in conventional and emerging areas of science and engineering. It also offers post graduate research and course work. The Institute has more than 45 departments and centers staffed by high caliber scientists. The Institute offers an opportunity for young researchers to pursue doctoral and post-doctoral studies in science subjects and engineering subjects. The institute also offers undergraduate program by providing an opportunity for young scientist.

Objectives of the study:
 To analyze the yearly growth of publications and it related citations.  To analyze the document type-wise distribution of publications.  To know the top subject-wise publications.
 To know the top country-wise publications.  To know the top source/journal-wise publications.  To identify the prolific authors wise distributions of Publications.  To identify the highly cited papers with Citation Map from Indian Institute of Science, Bangalore

Material and methods
From Web of Science database the data collected for the period 1999-2020. It can be seen that nearly 32191 bibliographic records of contribution by Indian Institute of Science Bengaluru, India researchers over the period of 22 years. The researcher applied a search strings "Indian Inst Sci" that has used for related information abstraction from the database of Science Citation Index total 21 years to download related data. A total of 32191 records are downloaded by using Web of Science inbuilt software applications as per the objectives of the study. Further based on citation per paper with number of high quality papers are also applied to find out the quality. The study aims to analyze the thrust areas of research concentration.

Document wise Distribution of Publications
The table 2 depicts the top 10 document wise distribution of articles published in the journal during 1999 to 2020. The productivity of scientists spreads over variety of publication media, such that journal articles; article, proceedings paper; Meeting abstract, review; letter; editorial materials; correction; meeting abstracts; article, book chapters; correction, Item about an individual and other news items.

Shows journal articles is top ranked with 25666 (77.15%) and News item is lowest rank with 31 (0.09%)

Subject Wise Distributions of publications
The table 3 depicts the top 10 subject-wise distribution of articles published in the journal during 1999 to 2020 Materials Science Multidisciplinary subject is top ranked with 5051 (21.03%) publications, followed by Engineering Electrical Electronic subjects with 3813 (8.09%) publications, while Physics Applied subject ranked third with 3009 (14.74%) publications and followed by remaining subjects.

In this analytical period, authors were published 32191 paper contributions scattered over 500 premier journals. The first 10 of authors are identified highest contributors of research at Indian Institute Science, Bengaluru. The

Citation Map of Highly Cited Authors
A Citation Map shows that the citation relationships between a paper and other papers using various visualization tools and techniques. Citation mapping analysis can be applied as subject similarity indicators. It is defined as "the frequencies with two documents are cited together". (Source: Web of Science Database)

Citation Map of Schuh, Christopher A.
Out of the total 32191 numbers of publications, author Schuh, CA is Global Citation Scores 1890 and single paper received 13 citations. The ACPP of Schuh, CA 21.54. The h-index is 9 and below figure 8 shows the citation map.

Conclusion
In my research study discloses the following findings.

Acknowledgments
This paper would not be complete without acknowledging the Thomson Reuters Web of Science database. Of course the paper collected 22 years data has been collected form Web of Science database due to this the paper accomplishment successfully. As I knew without data it is not possible to complete the objectives of these study in this paper.
I also takes this opportunity to thanks all authors in the references I has been mentioned in the bellow. Who are published in the previous years, I have been referred their published article and got clear idea to write this paper successfully.

Disclosure of conflict of interest
As the paper is authored by single author so there is no conflict of interest.
