Webometric analysis of departments of librarianship and information science: a follow-up study

This paper reports an analysis of the websites of UK departments of library and information science. Inlink counts of these websites revealed no statistically significant correlation with the quality of the research carried out by these departments, as quantified using departmental grades in the 2001 Research Assessment Exercise and citations in Google Scholar to publications submitted for that Exercise. Reasons for this lack of correlation include: difficulties in disambiguating departmental websites from larger institutional structures; the relatively small amount of research-related material in departmental websites; and limitations in the ways that current Web search engines process linkages to URLs. It is concluded that departmental-level webometric analyses do not at present provide an appropriate technique for evaluating academic research quality, and, more generally, that standards are needed for the formatting of URLs if inlinks are to become firmly established as a tool for website analysis

Web Impact Factor and link analysis of Central University Websites of North Eastern States of India

This study was conducted to observe the websites of Ten Central Universities situated in the north-eastern states of India and find out the three different Web Impact Factors viz. Simple, Revived & External Web Impact Factors of the websites under study. This paper shows the status of those websites finding out different number of hyperlinks to and from the websites. The paper also shows how the numbers of webpages in a websites as compared to the number of different links plays huge role in the utility of the website

Global Visibility and Web Impact of Leading Universities of SAARC Nations

In the present time, the World Wide Web (WWW) is one of the main platforms for every forum who wants to be recognized on in the ‘factual world’. At the academic level, universities have to play significant part for communicating scientific and cultural achievements. Publication by scholars of the institutions on the internet I snot only a tool for scholarly communication but it is also a way to reach larger audiences and thus represents the performance of the institutions globally. Thus, there have been numerous endeavours to develop the web indicators that can eventually lead to build a university’s rankings (Aguillo, Ortega & Fernandez, 2008). In this milieu, the Web Ranking of Universities originally aims at promoting Web publications. The Webometrics ranking is not only centralized towards scholarly output but also in other indicators which may reflect better global quality of scholars and presence of research institutions worldwide. The present study made an attempt to explore the top universities of SAARC nations in order to find out their performance, web-presence and impact. It has been observed from the study that Indian universities are performing better than other SAARC nation universities in terms of average world rank, continental rank, impact rank and openness rank while as Pakistan outpace in terms of average presence rank. This indicates that Indian universities have better scholarly output though Pakistan universities are more visible on the WWW

ArticleRank: a PageRank-based alternative to numbers of citations for analysing citation networks

Purpose - The purpose of this paper is to suggest an alternative to the widely used Times Cited criterion for analysing citation networks. The approach involves taking account of the natures of the papers that cite a given paper, so as to differentiate between papers that attract the same number of citations. Design/methodology/approach - ArticleRank is an algorithm that has been derived from Google's PageRank algorithm to measure the influence of journal articles. ArticleRank is applied to two datasets - a citation network based on an early paper on webometrics, and a self-citation network based on the 19 most cited papers in the Journal of Documentation - using citation data taken from the Web of Knowledge database. Findings - ArticleRank values provide a different ranking of a set of papers from that provided by the corresponding Times Cited values, and overcomes the inability of the latter to differentiate between papers with the same numbers of citations. The difference in rankings between Times Cited and ArticleRank is greatest for the most heavily cited articles in a dataset. Originality/value - This is a novel application of the PageRank algorithm

Web manifestations of knowledge-based innovation systems in the UK

Innovation is widely recognised as essential to the modern economy. The term knowledgebased innovation system has been used to refer to innovation systems which recognise the importance of an economy’s knowledge base and the efficient interactions between important actors from the different sectors of society. Such interactions are thought to enable greater innovation by the system as a whole. Whilst it may not be possible to fully understand all the complex relationships involved within knowledge-based innovation systems, within the field of informetrics bibliometric methodologies have emerged that allows us to analyse some of the relationships that contribute to the innovation process. However, due to the limitations in traditional bibliometric sources it is important to investigate new potential sources of information. The web is one such source. This thesis documents an investigation into the potential of the web to provide information about knowledge-based innovation systems in the United Kingdom. Within this thesis the link analysis methodologies that have previously been successfully applied to investigations of the academic community (Thelwall, 2004a) are applied to organisations from different sections of society to determine whether link analysis of the web can provide a new source of information about knowledge-based innovation systems in the UK. This study makes the case that data may be collected ethically to provide information about the interconnections between web sites of various different sizes and from within different sectors of society, that there are significant differences in the linking practices of web sites within different sectors, and that reciprocal links provide a better indication of collaboration than uni-directional web links. Most importantly the study shows that the web provides new information about the relationships between organisations, rather than just a repetition of the same information from an alternative source. Whilst the study has shown that there is a lot of potential for the web as a source of information on knowledge-based innovation systems, the same richness that makes it such a potentially useful source makes applications of large scale studies very labour intensive.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Advantages and Disadvantages of the Webometrics Ranking System

Today, there are several well-known global ranking lists for ranking universities in the world. While some of them ranked only a few hundreds of best and most influential universities, there are those that include a much larger number of ranking scientific institutions. One such global list which ranks the largest number of scientific institutions and scientists in the world is called Webometrics list. This list is very important for less developed economies and developing countries which have not established a sufficient quality control system of higher education quality, so this list serves as a corrective to the international evaluation of a wide range of universities in the world. In such a complex IT system of ranking an extremely large number of institutions and scientists, this system shows some disadvantages when ranking, which of course can be overcome by introducing certain improvements within the system of ranking. Systems that perform the collection, analysis, and indexing data have their advantages and disadvantages, which can sometimes lead to a misinterpretation of the data collected. Among other things, we will consider the possible solutions which would improve the rating system and prevent possible manipulation and uncertainty in the presentation of current and final results ranking
