International Journal of u- and e- Service, Science and Technology Vol. 4, No. 4, December, 2011 15 Quantitative Evaluation of Website Quality Dimension for Web 2.0 Environment Rajeev Saha and Sandeep Grover YMCA University of Science & Technology, Faridabad, Haryana – 121006 INDIA rajeevsaha@gmail.com, groversandeep@hotmail.com Abstract Measuring website quality has been a major concern since the invention of web. Moreover with the advancement of web technology the dimensions to evaluate quality kept on changing. As such it becomes difficult to analyze and focus upon the critical dimensions which should be paid more attention relative to others. Additionally comparing similar websites on quality front need some quantitative approach. In such a scenario, the necessity to develop a quality system model for web 2.0 environment arose which could be pursued quantitatively. Key website quality dimensions are identified and discussed. The effect of interactions of identified website quality dimensions among themselves and overall effect on website quality has been quantified. The purpose of this paper is to represent the effect of ‘website quality dimension in web 2.0 environment’ in terms of a single numerical index by considering their inheritances and interactions. The practical implication of this approach is to provide a methodology for website managers in order to evaluate key quality attributes affecting overall website quality. Keywords: Web 2.0 environment, website quality, graph theory 1. Introduction With increasing rate of growth of rich internet applications, the factors defining its environment change in continuum. Many factors considered important during web 1.0 environment seem trivial in web 2.0 environment. Web 2.0 environment generally employ combination of one or more technologies such as AJAX (Asynchronous JavaScript And XML (Extended Mark-up Language)), Mash up, Flux, etc. in website development, providing richer user experiences through robust functions and elegant user interfaces [1-3]. The focus of such development is getting real time interactions between websites and users or among users, thereby enhancing the website quality and rich user experience. Web 2.0 environments are all about harnessing collective intelligence. Collective intelligence applications depend on managing, understanding, and responding to massive amounts of user-generated data in real time. Thus, real time data usage is the backbone of the next generation of web 2.0 applications. The most significant characteristics that a core ‗Web 2.0 service‘ portrays could be summarized as: a) Web as Platform: Applications based on web 2.0 need not rely on the browser of a particular operating system (Mac, Mobile based or Windows). Contrary to the earlier concept of relying heavily on downloading supportive programs onto the desktop for
