Abstract : Webometrics is concerned with measuring aspects of the web: websites, web pages, parts of web pages, words in web pages, etc. This study examines 40 central universities websites in India. Investigates domain systems of the websites, analyses the number of webpages and link pages and calculates the simple web impact factor, self link web impact factor, external link web impact factor and revised web impact factor for Central universities in India and ranks the websites as per the WIF. It also develops a novel network diagram showing link structures between web nodes in webometric analysis. This study warns against taking the analogy between citation analysis and link analysis too far.

Abstract : The volume of world wide web (WWW) is increasing enormously due to a world wide move to migrate information to online sources. To search some information on WWW, search engines are used, which when presented with queries, return a list of web pages ranked on the basis of estimation of relevance. Generally the search engines due to the abundance of information available on the web return millions of pages. But user studies indicate that a common user browses through top 10 or 20 documents only. So it’s all-important to get into those top 10 documents. To achieve this web authors are increasingly beginning to rely on underhand techniques to ensure their sites get seen, in turn affecting the performance of search engines. The existing measures to evaluate these systems’ performance are not adequate in the current world of highly interactive end-user systems. In this study a metric 'Ranked Precision' is proposed to evaluate the performance of search engines.

Abstract : Sources of information available via the Internet are increasing exponentially, leading to steady increase in the use of Internet for education and research. Since past few years, free online information sources like ejournals, e-books, e-databases have increased considerably. Earlier, information and knowledge were passed by word of mouth or through manuscripts, and communication was a slow process. Today, it is passed from one individual to an infinite number of other users through a number of media and formats which makes rapid and widespread dissemination of information possible. This paper discusses utilisation of digital resources by faculty and research scholars of Manonmaniam Sundaranar University, Tirunelveli. Results show that 67.14 per cent of the faculty is familiar with the use of digital resources, and majority of these members are using digital resources for research purpose. Study also reveals that majority of the faculty members are learning the required skills for the usage of digital resources through self-study.
