Information Security Management Handbook

Discusses the concept of data mining that has emerged as a technique of discovering new meaning in data implicit in a large data warehouse, in order to facilitate better strategies and smart decisions. The standard tasks involved in data mining process are explained. Such pattern-seeking techniques usually performed with a wide range of related areas (viz. statistics, neural networks, genetic algorithms, machine learning, pattern recognition, knowledge-based systems, etc.) are described. Draws attention to useful applications of data mining in varying degrees and illustrates the benefit of this powerful technology with several instances of providing solutions to challenging problems. Also focuses on bibliomining opportunities to be useful to information retrieval, semantic analysis of unstructured texts, web-usage mining and to make proactive as well as knowledge-driven decision across library services; that help researchers in linking information for novel discovery and insight. The discussion illuminates the wrong things that happen with data mining applications and cautionary tales for avoiding serious consequences. Suggests use of data mining in combination with other techniques of evaluation, exploiting large data warehouses by skilled specialists, and advises for ethical uses without privacy invasion.

Usefulness and applications of data mining in extracting information from different perspectives

The scholarly output of the new coronavirus research has been proliferating. During five months, an amount of 14,588 scientific publications about nCoV-2 and COVID-19 has been generated intensively (as indexed in Scopus on 31 May 2020). Such a knowledge outburst has created ample interest in understanding the research landscape of this newly configured area. This paper demonstrates on scientometric dimensions of the novel coronavirus (2019-nCov) research using quantifiable characteristics of the publication dataset. Findings reveal that the rate of publication growth (1600%) is very significant to a synergic response of the researchers to combat with the most extended sequence of an RNA virus. Indeed their response has geared up to an average of 100 articles per day. Many scholarly publishers have disclosed their preprint servers to make the publications available immediately, even by enabling Open Access. The scientific contents have published in more than 500 journals from 240 academic publishers. While the top-ten publishers occupied almost 70% of the articles, then about 25% of the studies were sponsored by 300 funding agencies. Among the notable journals Lancet, Nature, BMJ, JAMA, JMV, and NEJM are prominent. Findings also reveal that majority of the contributions have occurred in Medical Science, focusing on virology, immunology, epidemiology, pharmacology, public health, critical care, and emergency medicine. However, the closely associated terms are virus transmission, infection control, asymptomatic, quarantine, pneumonia, human, disease severity, clinical trials, viral pathogenesis, pandemic, risk, and mortality. The study suggests that academic hubs are located mostly in the USA, China, Italy, and the UK. Among the productive institutions; Huazhong Univ (China), Tongji Med. College (China), Harvard Med. School (USA), Univ of Milan (Italy), INSERM (France), UCL (UK) are outstanding. The G7 countries together produced 50% of the global research output on nCov-2. It also noted an encouraging trend of collaborative research across many countries and disciplines, where the values of CI (6.46), DC (0.79), and CC (0.59) are very significant. It examines the geographical diversity of the collaborating authors, thereby visualized their linkages via co-authorship occurrences. Finally, it analyzed the publications' impact to showcase the most influential contributions of the new coronavirus research.

Visualizing the knowledge outburst in global research on COVID-19.

The quantification of scholarly performance has become an obvious necessity in many academic pursuits. Evaluation of research output is, therefore, an integral element of R&D institutions worldwide. This paper critically scrutinizes the literature on research productivity concerning scientific institutions (include universities and departments) in an informational context. It provides a thorough review to map the quantum of knowledge relating to ‘institutional research productivity’ correlating the Indian vista. The paper also offers a few recommendations to undertake evaluative studies with caution. Thus it shows a coherent picture of this emerging area in the sociology of science.

Evaluation of Institutional Research Productivity

Marriage information is an integral part of the knowledge base in any civilized society. In India, several non-government agencies as well as de-institutionalized sources provide a great variety of marriage related information in different domains of the society. Despite various modes in transferring matrimonial information, increasing use of social networks offers new opportunities for newer matrimony services. The purpose of this paper is to present the state-of-the-art of popular matrimony service portals emerged in India for providing SDI (selective dissemination of information) based personalized services to multifarious groups of the nation. Addresses of selective portals provide glimpses of current Indian activities on matrimonial information systems and services. It also examines the potentialities of the four biggest matrimonial players (viz. shaadi, bharatmatrimony, jeevansathi and simplymarry) in the country consistent with the present and anticipated needs of the marriage-information-seekers. Comparison has been carried out based on the web metrics. The paper noticed that online matrimony services would have ever-increasing importance in satisfying the objectivity of social networking practices.

Social Networks Enabling Matrimonial Information Services in India

Information security has been a crucial issue in modern information management; thus cryptographic techniques have become inevitable to safeguard the digital information assets as well as to defend the invasion of privacy in modern information society, and likely to have far reaching impact on national security policies. This paper demonstrates the intellectual development of cryptographic research based on quantifiable characteristics of scholarly publications over a decade of the present century (2001 to 2010). The study critically examines the publication growth, authorship pattern, collaboration trends, and predominant areas of research in cryptology. Rank list of prolific contributors, productive institutions, and predominant countries have been carried out using fractional counting method. Strenuous efforts have been made to perform the activity index (performance indicator) of JOC, to determine the degree of collaboration in quantitative terms, to ascertain the collaboration density, as well as to test the empirical validation of Lotka's law in this scientific specialty. Major findings reveal that performance of JOC in cryptographic research corresponds precisely to the growth of world's publication activity (activity index = 1.1) over a decade of time; single-authored papers count only 25 % and average authorship accounts for 2.4 per paper; an increasing trend of multi-authored publications and a significant degree of collaboration (DC = 0.74) implies that cryptographers prefer to work in highly collaborative manner; author productivity distribution data partially fits the Lotka's law, when the value of ? (productivity parameter) approximated to 2.35 (instead of 2) and the number of articles does not exceed two. While large majority of collaborations constituted across the countries (56 %), then adequate amount of inter-country bilateral and multilateral collaboration signifies higher density or greater strength in the research network; most of the potential collaborators are emanated from 10 institutions of 5 different countries; however, cryptographic research is dominated by USA and Israel. More interestingly, vast majority among top-twenty ranked productive authors are affiliated in USA and Israel; Yehuda Lindell is found to be the most prolific author followed by Rosario Gennaro (USA), Tamir Tassa (Israel), Jonathan Katz (USA), etc.; Anglo-American institutions are more open than their overseas competitors; University of California (six centers) is placed on the top of the productive institutions. The study entails distinct subject clusters (research streams); and author-assigned keyword frequencies revealed that cryptanalysis, discrete logarithm, elliptic curve, block cipher, provable security, cryptography, secure computation, oblivious transfer, public-key encryption, zero-knowledge are more prevalent and active topics of research in cryptology. The implications of empirical results to the field are discussed thoroughly, and further analyzes are proposed to visualize this assessment in a better way.
