The paper focuses on the Web presence and visibility of Asian countries websites. The paper tries to highlight the Web presence using some webometric indicators like Internet access, webpages, number of Internet users, and link studies. The study analyzes the web presence using popular search engines like Altavista, Google, Yahoo and MSN. An attempt has also been taken to find out the Web Impact Factor (WIF) for selected Asian countries. The result shows that China (43.7%), Japan (16.7%) and India (10.4%) occupy highest web presence amongst Asian countries based on the total number of effective Internet users. China being the second highest number of Internet users having 11.8% after USA (19.7%) followed by India with 4.9% of world Internet Users and Japan is having the highest number of webpages followed by China and South Korea.
Web contents are interlinked at each other through hyperlinks. Inter-linking nature of web explores significant sources of information. In the context of exploring hyper-linking behaviour of the web and retrieving relevant information, search engines and web crawlers play a predominant role as data sources but search engines had mostly withdrawn their supports after December 2011. An attempt has been taken to evaluate search engines (Google, AoL, Bing, Yahoo!) using some criteria and found that AoL has the highest coverage among these search engines. The paper also identifies various alternative data sources to carry out webometric research. The finding of the study shows that majestic.com is a predominant and comprehensive data source among alternative data sources in webometric research.
Immersive environments refer to a computer-simulated 3-dimensional virtual world. Libraries worldwide have been adopting and implementing new immersive technologies to enhance users’ experience and learning. The Central Library of IIT Kharagpur offers (i) web-based augmented reality (WebAR), (ii) virtual reality (VR), and (iii) data visualisation immersive services. This research investigates the users’ perceptions on factors that influence their satisfaction with WebAR/VR services. The study surveyed 135 random users to note their immersive library experience; out of them, only 100 users responded to our survey. The results show that 90 per cent of the respondents were satisfied with our services. Secondly, the respondents revealed that data privacy, health, and safety were some of the critical factors that influenced their satisfaction. Further, 14 per cent were apprehensive in terms of their health & safety. In fact, these users reported vision problems, disorientation, dizziness, sweating, and nausea. Based on the data collected, we prepared a framework, using The DELOS DL reference model for information delivery, along with educational and research activities. We believe that this study would lend crucial insights to academic libraries that may be planning to adopt and implement AR/VR as part of their immersive environment.
The article investigates the relationship among top ten world universities (TTWU), top ten Asian universities (TTAU) and top ten Indian universities (TTIU) based on the exploratory study of weblink analysis. Inlinks and outlinks analysis try to explore the relationship among these universities. The findings suggest that although TTIU are generating 3.71 % outlinks to TTWU but receives only 0.67 % inlinks from them. On the other hand, inlinks and outlinks to TTAU are far less than TTWU. An interesting result reflects that the percentage of inlinks and self-links for top ten Indian (30.51% and 69.49%) and Asian universities (31.45 % and 68.55 %) are less than top ten world universities (55.25% and 44.75%).
