Evaluation of library websites is a key to realize the extent of user acceptance to the website and to improve overall quality of website. Usability is a highly recognized factor to determine how easy to use the website. The models of usability evaluations evaluate the ease of use of website operations and see whether the users can perform their tasks easily. Moving on further, this study has been undertaken in context of library websites in Sri Lanka with the main purpose of exploring the favourable weights of the seven key dimensions and 20 measuring items with the aids of experts in the related field. These dimensions and measuring items were identified from our previous study which have been tested its reliability and validity in assessing library website usability in Sri Lanka with the aids of actual library users in Sri Lanka. Fuzzy theories together with the extent analysis fuzzy analytic hierarchy process method were applied. It was expected to identify the relative importance of the criteria of interest while avoiding uncertainty, ambiguity, loss of data, and difficulties faced in assessment cycle. Triangular fuzzy numbers were used to represent the judgments on the relative importance between each pair of factors that makes experts consensus uniform rather than using linguistic values. The research findings concluded that satisfaction was the dimension that the experts considered most important in evaluating library website usability. The experts rated accessibility as the least important dimension.","PeriodicalId":448883,"journal":{"name":"Int. J.

The Internet has proven itself to be a valuable resource in the enhancement of knowledge production and dissemination. The purpose of the study was to establish how excessive non-academic use of the Internet detrimentally affects undergraduate students’ daily lives. Using survey design, a total of 390 University undergraduate students comprising mainly adolescents/ young adults were selected using stratified random sampling at two South African universities, namely Fort Hare and Nelson Mandela. Data were collected using the Modified Internet Addiction Test for Undergraduates (MIATU), a modification of Internet Addiction Test (IAT) questionnaire. 282 (72.3%) use of the respondents indicated that they make use of the Internet daily with 34.8% spending more than 10 hours. More than 60% have access to at least two electronic devices. Most of the respondents stayed online longer than intended (x 2.88), slept less at night due to Internet use (x 2.63) and hence spent less time studying owing to Internet surfing (x 2.27). Furthermore, the amount of time spent on the Internet had a significant relationship with the level of influence the use of the Internet had on respondents (B = 0.250, t = 4.850, p < 0.05). The findings are indications that the excessive amount of time spent on the Internet served as a distraction from school work, a situation that put students at a disadvantage in as far as academic productivity was involved. These findings clearly suggest that the uncontrolled use of new media is both a hazard and a potential danger to academic productivity.","PeriodicalId":448883,"journal":{"name":"Int. J.

Therefore, multi-cloud environment (MCE) is a promising solution in competitive market. Nevertheless, uncertainty relevant to security principles such as availability, integrity and confidentiality is the main challenge in this ambit. Virtualization as a key technology is pervasively being exploited in datacenters; so, variety known/unknown cybersecurity attacks threat mutli-tenant cloud datacenters. On the other hand, each service provider publishes same web services with different pricing scheme and different security level. We propose a framework in which every cloud can register its pricing scheme and its cybersecurity threats on a data warehouse via its broker module. Later, each security level can be measurable by our novel approach. Then, the web service composition problem is modeled to multiobjective optimization by monetary cost and cybersecurity viewpoints. We design and implement a multi-objective genetic approach to combine web service composition based on user cost and security requirement. Our proposed method well constitutes Pareto curve by finding non-dominance points. Simulation on different scenarios proves our approach dominance against a single objective heuristic ones.","PeriodicalId":448883,"journal":{"name":"Int. J.

Unfortunately, identifying localizable queries is not sufficient per se for performing successful location-sensitive searches, unless there exists a geo-referenced index of data sources against which localizable queries are searched. In this paper, we propose a novel approach towards the automatic construction of a geo-referenced search engine index. Our approach relies on a geo-focused crawler that incorporates a structural parser and uses GeoWordNet as a knowledge base in order to automatically deduce the geo-spatial information that is latent in the pages’ contents. Based on location-descriptive elements in the page URLs and anchor text, the crawler directs the pages to a location-sensitive downloader. This downloading module resolves the geographical references of the URL location elements and organizes them into indexable hierarchical structures. The location-aware URL hierarchies are linked to their respective pages, resulting into a georeferenced index against which location-sensitive queries can be answered.","PeriodicalId":448883,"journal":{"name":"Int.
