Quality modelling and metrics of Web-based information systems

In recent years, the World Wide Web has become a major platform for software applications. Web-based information systems have been involved in many areas of our everyday life, such as education, entertainment, business, manufacturing, communication, etc. As web-based systems are usually distributed, multimedia, interactive and cooperative, and their production processes usually follow ad-hoc approaches, the quality of web-based systems has become a major concern. Existing quality models and metrics do not fully satisfy the needs of quality management of Web-based systems. This study has applied and adapted software quality engineering methods and principles to address the following issues, a quality modeling method for derivation of quality models of Web-based information systems; and the development, implementation and validation of quality metrics of key quality attributes of Web-based information systems, which include navigability and timeliness. The quality modeling method proposed in this study has the following strengths. It is more objective and rigorous than existing approaches. The quality analysis can be conducted in the early stage of system life cycle on the design. It is easy to use and can provide insight into the improvement of the design of systems. Results of case studies demonstrated that the quality modeling method is applicable and practical. Practitioners can use the modeling method to develop their own quality models. This study is amongst the first comprehensive attempts to develop quality measurement for Web-based information systems. First, it identified the relationship between website structural complexity and navigability. Quality metrics of navigability were defined, investigated and implemented. Empirical studies were conducted to evaluate the metrics. Second, this study investigated website timeliness and attempted to find direct and indirect measures for the quality attribute. Empirical studies for validating such metrics were also conducted. This study also suggests four areas of future research that may be fruitful

A Techno-Social Approach for Achieving Online Readership Popularity

Understanding what drives readership popularity in online interactive media has important implications to individual practitioners and net-enabled organizations. For instance, it helps generate a success “formula” for designing potentially popular websites in the increasingly competitive online world. So far, research in this area lacks a unified approach in guiding the design of online interactive media as well as in predicting their successful adoption and use, from both technological and social orientations. Drawing upon the media success literature and related social cognition theories, we establish a techno-social model for achieving online readership popularity, accounting for the impacts of technology-dependent and media-embedded characteristics. The proposed model and hypotheses will be tested by a content analysis of 100+ very popular weblogs and survey of 2000+ active weblog readers. This research carries significant value for sustaining community- and firm-based user networks that have been recognized as an important source of social and knowledge capitals

E-Commerce Applications Ranking

The paper presents the cycle of development of e-Commerce applications. The e-commerce applications are analyzed being considered to be a subject for complex evaluations. A set of criteria and factors are presented being considered relevant for e-commerce applications used in complex assessments. A ranking algorithm is proposed based on the AHP (Analytic Hierarchy Process) process, which was implemented and tested with online application IAID. The objective of this paper is to build, implement and test this algorithm with the online application IAID.E-Commerce, Hierarchy, Evaluation Criteria, Analyses, Ranking Algorithm

On the Impact of Stereo 3D Image on User Learning in the Web Environment

Recent technological breakthroughs have cultivated a Web3D movement. It is safe to say we will see more and more stereo 3D images on websites. This research investigates how stereo 3D can be employed on websites to influence user learning. A set of theory-driven hypotheses were developed to compare websites with embedded stereo 3D and websites with either static 2D images or virtual realities in terms of user comprehension, user control in learning, and user adoption of the website. Controlled experiments were conducted to test the hypotheses. The results show that stereo 3D can reduce learning effort and induce positive user attitude. At the same time, it can also reduce users’ perceived control. While answering some fundamental research questions, this research also reveals that more investigation is needed regarding the use of stereo 3D on websites
