Despite a large number of studies in personalizing e-learning systems, only a few sufficiently cover the impact of personalization on university emails. Either universities impose the use of university email or students are reluctant to use it. For instance, It was found that at King Abdulaziz University only 23% of students were using the university email to communicate regularly, unlike the faculty members, who showed an 80% commitment. However, this paper attempts to investigate the effect of applying different personalized systems on the university email and whether using adaptation and adaptability techniques in the university email will cover the huge gap between the university and its members. Specifically, frameworks were built to evaluate the efficiency, frequency of error occurrence, effectiveness, and user satisfaction in each experiment. We focused on testing the usability of personalized email against the existing university email and then evaluate which approach (adaptive, adaptable, or mixed-initiative) is more favorable to personalize the university email. These were conducted and evaluated using 40 subjects. Interestingly, results show that subjects with personalized emails were most efficient and satisfied as well as errors were reduced by 42%. Furthermore, significant differences were found between the three approaches (adaptive, adaptable, and mixed-initiative), and the adaptive approach was the most preferred by the respondents. A set of empirically derived guidelines was also discussed as a basis for developing a suitable university email structure.

“…User testing is considered as an important approach in order to identify the problems encountered using a product or a website (Barnum, 2002;Dumas and Redish, 1999). In user testing, users are observed, while they perform the pre-determined tasks related to website (Bastien, 2010;Roy and Pattnaik, 2013). During the tests, users are asked to think aloud and this is an effective technique called "Think Aloud Protocol" to get the verbal feedback of the users (Ericsson and Simon, 1980;Lazar, 2006;Nielsen, 1993).…”

“…Questionnaires are useful post-data collection instruments in order to measure the user satisfaction and to obtain the user comments on the system usability (Dumas and Fox, 2009;Roy and Pattnaik, 2013;Rubin and Chisnell, 2008). User satisfaction was accepted as an important indicator for website usability by several studies (Bertot et al, 2006;King and Jannik, 2005;Ferreira and Pithan, 2005;Preece et al, 1994;Roy and Pattnaik, 2013). In accordance with this statement, users are asked to rate the website in the post-questionnaire, after the tasks are completed on that site by the user.…”

“…In several studies (Casalo et al, 2007;Lavie and Tractinsky, 2004;Pearson et al, 2007) ease of use is identified as an important factor for web users, and task completion time is the major indicator for that factor. In this manner, task completion time and task success ratio were selected as the performance indicator (Roy and Pattnaik, 2013). Thus, time spent for each task was recorded until the participant completed the task successfully or unsuccessfully.…”

Purpose – The purpose of this paper is to statistically explore the relationship between web usability and web presence of the universities. As a case study, five Turkish universities in different rankings which were selected from Webometrics rankings were evaluated and compared. Design/methodology/approach – Two different methods were employed for performing usability evaluation of the selected universities: a user testing was used to measure the user performance on the selected tasks and a questionnaire to assess the user satisfaction on the website use. Both usability evaluation methods were applied on the pre-determined tasks for each university by participation of 20 subjects. After the usability evaluation, the universities were ranked in terms of usability results and finally, the relationship between web usability and web presence of universities was statistically investigated by using Kendall’s rank correlation. Findings – Several common usability problems which were asserted by related previous studies were identified at the end of usability evaluation of university websites. The usability results also revealed that selected Turkish university websites suffer from numerous usability problems. Further, a strong positive correlation (p < 0.05) between the usability of the university websites and their web presences were identified. Hence, the participants showed a higher success and satisfaction while performing the tasks on the university websites which have strong web presences. Practical implications – The findings from this study have practical implications for universities. Correlation results showed that universities can improve their web usability by giving importance to their web presence volumes. Universities can estimate their web usability levels by investigating their web presence rankings and they can also raise their rankings in Webometrics ranking system by improving the usability of their websites. Moreover, university web developers can design more usable and more user-friendly websites by avoiding usability and design problems identified through usability evaluation. Originality/value – Different from the prior research efforts focussing on usability of educational web pages, this study contributes to the growing literature by statistically exploring the relationship between web presence and web usability of universities. This study is also precious from the point of view that it is one of the first attempts to evaluate and compare usability levels of a set of universities’ websites from Turkey.

“…Roy and Pattnaik [10] in 2013 have proposed usability evaluation techniques to evaluate the usability of web services based on specific usability attributes. The authors identified two new usability factors namely device independence and provision for physically disabled person in addition to the current attributes which enriches the quality of the web services and increase the global value of the products.…”

Cloud computing is a style of computing which thrives users requirements by delivering scalable, on-demand and pay-per-use IT services. It offers different service models, out of which Storage as a Service (StaaS) is the fundamental block of Infrastructure cloud that fulfills user’s excess demand of elastic computing resources. But considering the competitive business scenario choosing the best cloud storage provider is a difficult task. Thus, usability is considered to be the key performance indicator which evaluates the better cloud storage based on user’s satisfaction. This paper aims to focus on the usability evaluation of StaaS providers namely Google drive, Drop box and One drive. This paper proposed a fuzzy based AHP model for measuring user satisfaction. Usability evaluation is carried out based on user feedback through Interview and Questionnaire method. Analysis of user feedback is done based on the fuzzy approach in order to remove vaguness. Whereas, AHP model is used for measuring satisfaction degree of the different cloud storage services and it solves the problem of selecting best cloud storage.
