This study aims to evaluate the publications in Encephalitis journal during the year 2008-2017. The data were retrieved from the Web of Science database maintained by Thomson Reuters, analyzed using tools like HisCite and Microsoft Excel. The adopts various method like relative growth rate, exponential growth rate, doubling time, degree of collaboration, etc. Focusing on various aspect of the journal such as document types, year-wise distribution of publication, authorship pattern, institutions involved, country-wise, keyword wise distribution, etc. The study reveals that Encephalitis published 6,405 articles. The highest number of publications in terms of articles was in the year 2017 followed by 2016. The study shows that most of the papers (93.97%) were contributed jointly whereas 6.02% of papers were contributed by single authors. It reveals that Vincent A. is the most productive author contributing 65 (1.01%) of articles in Encephalitis. The country-wise distribution shows that the highest number of contribution comes from the USA: 2,331 (36.39%).

Review Of Literature

Ritu Gupta, Gupta, B.M., and Mueen, M. (2014) have analysed the publications of limbic encephalitis during the period 2004-2013. They found that the maximum publications with account of 154 were in the year 2013 & minimum publications with a count of 43 were in the year 2004. They enunciated that totally 901 records were published during that period retrieved from Scopus data base. The study reveals that the annual average growth rate of 17.27% and an average citation impact per paper of 5.76%. The largest publication share (91.56%) in limbic encephalitis came from medicine, followed by neurosciences (34.52%). Three countries namely Spain, Austria, and U.K, out of 10 have achieved higher share of relative index than the average relative citation index of 1.91 of top 10 countries during 2004-13.

Ritu Gupta, and Gupta, B.M. (2016) discussed the research on “Japanese encephalitis” is 2496 publications indexed in Scopus data base during 2003-12, witnessing an annual average growth rate of (7.41%) and citation impact per paper of (5.26%). Japanese encephalitis publication out came from 79 countries, of (UK, India, China, Japan, etc.) accounted for 88.90%) global publication share during 2003-12. The largest publication share (65.06%) of out on Japanese Encephalitis came from medicine, followed by immunology & microbiology (40.71%), biochemistry, genetics & molecular biology (18.55%), pharmacology, toxicology & pharmaceutics(9.33%), veterinary science (9.13%), neurosciences (6.69%), during 2003-12. Six countries, namely UK (2.01), USA (1.91), France (1.27), Thailand (1.19), Australia (1.15) and South Korea (1.04) have achieved relative citation rate above 1.

Key Terms in this Chapter

Scientometrics: The field of study which concerns itself with measuring and analysing scientific literature. Scientometrics is a sub-field of bibliometrics. Major research issues include the measurement of the impact of research papers and academic journals, the understanding of scientific citations, and the use of such measurements in policy and management contexts.

Encephalitis: An inflammation of the brain tissue. The most common cause is viral infections. In rare cases it can be caused by bacteria or even fungi. There are two main types of encephalitis: primary and secondary. Primary encephalitis occurs when a virus directly infects the brain and spinal cord. Secondary encephalitis occurs when an infection starts elsewhere in the body and then travels to your brain. Encephalitis is a rare yet serious disease that can be life-threatening. You should call your doctor immediately if you have symptoms of encephalitis.

Citation Analysis: The examination of the frequency, patterns, and graphs of citations in documents. It uses the pattern of citations, links from one document to another document, to reveal properties of the documents. A typical aim would be to identify the most important documents in a collection.

Impact Factor (IF) or Journal Impact Factor (JIF): A scientometric index which reflects the yearly average number of citations to recent articles published in that journal. It is frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factors are often deemed to be more important than those with lower ones.
