industrial experience with building a Web Portal product line using a lightweight reactive approach
Foundations of Software Engineering, 2005Co-Authors: Ulf Pettersson, Stan JarzabekAbstract:Imprecise, frequently changing requirements and short time-to-market create challenges for application of conventional software methods in Web Portal engineering. To address these challenges, ST Electronics (Info-Software Systems) Pte. Ltd. applied a lightweight, reactive approach to support a Web Portal product line. Unique characteristics of the approach were fast, low-cost migration from a single conventional Web Portal towards a reusable "generic Web Portal" solution, effective handling of large number of functional variants and their dependencies, the ability to rapidly develop new Web Portals from the generic one, and to independently evolve multiple Web Portals without ever losing a connection between them and the "generic Web Portal". The initial Web Portal was built using state-of-the-art conventional methods. The Web Portal was not flexible enough to reap the benefits of new business opportunities that required the company to rapidly develop and further maintain many similar Web Portals. To overcome the limitations of the conventional solution, a reuse technique called XVCL was applied incrementally. Over a period of three weeks, the conventional solution was converted into a Web architecture capable of handling nine Web Portals from a base of code smaller than the original Web Portal. In the paper, we describe the process that led to building the above Web Portal product line. We explain the difficulties in building an effective generic Web solution using conventional techniques. We analyze our reuse-based solution in qualitative and quantitative ways.

e government Web Portal adoption a service level and service quality perspective
Hawaii International Conference on System Sciences, 2014Co-Authors: Xiao Jiang, Shaobo JiAbstract:E-government Web Portal service level and service quality are critical factors that determine user's adoption and continuance use. The paper reports results of a study that examines user's adoption and continuance intention (CI) of e-government Web Portal from the perspective of service level and service quality. Three types of user groups are identified based on the purposes of use and the primary activities: information acquisition, information exchange, and transaction processing. Service quality is measured by Web Portal's information quality, design/function, reliability, security and privacy, and system responsiveness. A research model is proposed and tested using data based on a sample of 630 individual e-government Web Portal users in China. Results show that Web Portal's service quality affects user's adoption and continuance intention and the effect differs among different types of user groups. Implications based on the findings of the study are discussed in term of e-government Web Portal implementation.

e government Web Portal adoption the effects of service quality
E-service Journal, 2014Co-Authors: Xiao Jiang, Shaobo JiAbstract:E-government Web Portal service quality is a critical factor that determines user’s adoption and continuance use. The article examines Chinese citizens’ adoption and continuance intention (CI) of e-government Web Portal from the perspective of service level and service quality. Three types of user groups are identified based on the purposes of use and the primary activities: information acquisition, information exchange, and transaction processing. Service quality is measured by Web Portal’s information quality, design/function, reliability, security and privacy, and system responsiveness. A research model is proposed and tested using data based on a sample of 630 individual e-government Web Portal users in China. Our findings revealed that Web Portal’s service quality affects user’s adoption and continuance intention and the effect differs among different types of user groups. Finally, Implications of these findings are discussed.

Computer Self-efficacy and Its Relationship with Web Portal Usage: Evidence from the University of the East
International Journal of Computing Sciences Research, 2017Co-Authors: Rex Perez Bringula, Julius Jan M. Sarmiento, Roselle S. BasaAbstract:Purpose–The University of the East Web Portal is an academic, Web-based system that provides educational electronic materials and e-learning services. To fully optimize its usage, it is imperative to determine the factors that relate to its usage. Thus, this study, to determine the computer self-efficacy of the faculty members of the University of the East and its relationship with their Web Portal usage, was conceived.Method–Using a validated questionnaire, the profile of the respondents, their computer self-efficacy, and Web Portal usage were gathered.Results–Data showed that the respondents were relatively young (M= 40 years old), majority had master’s degree (f = 85, 72%), most had been using the Web Portal for four semesters (f = 60, 51%), and the large part were intermediate Web Portal users (f = 69, 59%). They were highly skilled in using the computer (M= 4.29) and skilled in using the Internet (M= 4.28). E-learning services (M= 3.29) and online library resources (M= 3.12) were only used occasionally. Pearson correlation revealed that age was positively correlated with online library resources (r= 0.267, p

Factors Affecting Faculty Web Portal Usability
Educational Technology & Society, 2011Co-Authors: Rex P. Bringula, Roselle S. BasaAbstract:The study investigated the factors that might significantly affect Web Portal usability. Results of the study were intended to serve as inputs for faculty Web Portal development of the University of the East-Manila. Descriptive statistics utilized questionnaire data from 82 faculty members. The data showed that most of the respondents were relatively young, were Master’s degree holders, were skilled in using the computer and the internet, had internet access at home, and were committed to using the Web Portal. Respondents perceived that the different Web Portal design-related factors were moderately evident in the existing faculty Web Portal. Multiple regression analysis showed that information content as a Web Portal design-related factor was the only significant predictor of Web Portal usability. Thus, the null hypothesis stating that faculty-related and Web Portal design-related factors do not significantly affect faculty Web Portal usability is accepted except Information Content. The study also discussed the guidelines for Web Portal developers, as well as the limitations and implications of the study for future research.
