Cloud Computing and its Applications in Library: A Review
(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Raja, S.; Krishnan, V.
Cloud computing have not been a new technology that suddenly appeared on the web but it is a new form of computing. Cloud computing is a kind of computing technology which facilitates in sharing the resources and services over the internet rather than having these services and resources on local servers/ nodes or personal devices. Cloud computing is a kind of computing technology which facilitates in sharing the resources and services over the internet rather than having these services and resources on local servers/ nodes or personal devices. The combination of servers, networks, connection, applications and resources is defined as 'cloud'. Application of cloud computing user would be able to browse a physical shelf of books, CDs or DVDs or choose to take out an item or scan a bar code into his mobile device. All historical and rare documents would be scanned into a comprehensive, easily searchable database and would be accessible to any researcher. Many libraries already have online catalogues and share bibliographic data with OCLC. More frequent online catalogues are linked to consortium that share resources. The combination of servers, networks, connection, applications and resources is defined as 'cloud'. This article describes models of Cloud computing, applications in library, advantages, disadvantages of cloud computing in library and its barriers.
International Research Publications on Education in Sri Lanka: A Scientomeric Study.
(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya,Sri Lanka., 2017) Navaneethakrishnan, S.; Raja, S.; Kupeshan, R.
Quantitative studies of scholarly communication activities tend to have a better understanding of phenomena of construction, dissemination and use of scientific and technical knowledge. Nowadays scientometrics is considered as a standard tool of science policy and research management. It is also realized that this is the opportune time for the library professionals to study the current trend of Sri Lankan education system in the view international scholars to identify the role of the libraries in fulfilling the obligations specified in these research studies. This study was carried out with the intention to analyze the international research publications on education in Sri Lanka. The process of selection of publications was utilizing scientometric approach of research publications indexed by the web of science (WoS) database. Quantitative research methodological approach was taken, based on scientometric analysis. Results of this study shows a total of 201 publications were released by the Global scientists in education during 2010-2016 which received 4873 citations. The mean number of publications per year was 16.57%. It states that globally 9.45percents of items were from lone authors, pursued by 16.42% authors by double authors etc. 0.91 percent of collaborative author’s articles released throughout the study periods. The value of a mean RGR of publications which declined from 3.32 in 2010 to 0.32 in 2016, simultaneously the values of doubling time (Dt) of publications expanded from 0.21 in 2010 to 3.04 in 2016. The high frequency keywords were “Sri lanka” 109 (54.2%, TCLS 14, TGCS 332). The foremost cited quotation is Katulanda P, 2008, diabetic med, V25, P1062, DOI 10.1111/j.1464-5491.2008.02523.x. The suggestion of this research is to setup an enabling environment for more studies across the nations on Sri Lankan education and international researchers need to be encouraged on this.
Research Performance of Cloud Computing in BRICS Countries
(Department of Library and Information Science, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Raja, S.
Research performance of BRICS countries has been studied using publications indexed in the Web of Science (WoS) database core collection. “Cloud computing” as a search term in the address tag fetched 2537 records and the period of coverage from 1989 to 2016. The downloaded data were analyzed using MS Excel, VOS Viewer, and HistCite software applications. The analysis revealed that there are 6767 authors from among 5 countries; 623 journals; 9 types of documents; 2130 institutions; 63,005 times cited by local and global references. 93.9% of publications are scholarly articles. The highest productive year is 2015 (28.6%) (TGCS- 843) and lowest is 1991 (TGCS-25). Of the 73 countries, Peoples R China stands first, USA and India in the second and third places respectively. “International Journal of Grid and Distributed Computing”, “IEEE Transactions on Parallel and Distributed Systems”, “Concurrency and Computation-Practice & Experience” are the most productive journals involved in this study. Among the 6767 authors, “Li J” has earned the highest publication. “Chinese Academy Science” and “Tsinghua University” dominate other institutions in terms of number of records. 63,005 cited references were measured from the data and most cited authors were “Armbrust M”, “BUYYA R”, and “Dean J”; most cited journals were “COMMUN ACM”, “FUTURE GENER COMP SY”, and “COMMUN ACM”.
