Revisión sistemática de los métodos de evaluación de experiencia de usuario de sitios web informativos

El presente trabajo de tesis consiste en una revisión sistemática, presentada como artículo científico, sobre los métodos de evaluación que son empleados actualmente para la evaluación de la experiencia de usuario en sitios Web informativos. El trabajo de investigación consiste en una revisión de la literatura para identificar los métodos, criterios y herramientas empleadas para evaluar la experiencia de usuario en sitios web de acuerdo a la definición planteada para ambos términos en la ISO 9241. Las investigaciones consideradas para la revisión fueron encuestas, estudios de casos, estudios comparativos y experimentos que incluyan la descripción de la metodología aplicada. El artículo fue publicado en Springer como parte de la participación en el evento "HCI International 2017", realizado en Vancouver (Canadá) en el 2017.Trabajo de Investigació

Developing design process model and measuring acceptance of polytechnic cooperative e-retail website

Research on the process model of e-retail web design using Content Management System (CMS) remains scarce. CMS is one way of developing website quickly, with less cost and usage of IT expertise. Researchers mostly focus on identifying the significant relationship towards particular website especially on web design and suggest for practical implementation. Previous studies on web development are on the architecture of CMS while the use of CMS attracts little interest among researchers. Only a number of researchers concentrate on the process development of e-retail website especially using CMS. To fill the practical gap, this research proposed a process model of e-retail website through SDLC and extended the model with the introduction of internet marketing. It was tested in the development of a e-retail website. Each stage is discussed in details along the way of the web development. After the website was successfully developed, this research examined the acceptance of e-retail website by measuring consumers’ behavioural intention and actual usage using Unified Theory of Acceptance and Use of Technology (UTAUT). In addressing the theoretical gap, this research provides an empirical test of three forms of self-efficacy (Computer Self-efficacy, Internet Self-efficacy, and Online Shopping Self-efficacy) and anxiety (Computer Anxiety, Internet Anxiety, and Online Shopping Anxiety) towards behavioural intention to shop online. The research subjects were 91,830 polytechnic students from 33 polytechnics in Malaysia. A total of 357 fulltime polytechnic students from five polytechnics in Malaysia have been involved in this research. From a list of students’ name, self-administered survey questionnaires were distributed at response rate of 77.8%. Correlation and Multiple Regression were used to test the significant relationship while Hierarchical Regression was used to test the moderator of gender. The research reveals that Performance Expectancy, Social Influence, Facilitating Condition and Online shopping Self-Efficacy are found to have significant effect on students Behavioural Intention to use polytechnic co-operative eretail business. E-retailer needs to encourage the potential customer to make on-line purchasing because it is no longer a norm against the use of the Internet and computer. The process model is readily transferable to another website so that it describes as sufficient for use. The future research shall apply the extended UTAUT in different subject (adult) and the process model shall extend until the Return on Investment (ROI)

Enhancing navigability in websites built using web content management systems

Websites built using Web Content Management Systems (WCMSs) usually provide their users with three types of access structures to surf their contents: indexes of categories, breadcrumb trails, and sitemaps. In addition, to find contents of his/her interest, a user can perform more or less advanced full-text searches. In this paper we propose an automatic approach to extend the navigation structure of websites developed using WCMSs with Semantic Navigation Maps (SNMs), a complementary navigation structure that enables linking and navigating contents based on their lexical similarity. The approach uses an information retrieval technique (namely, Latent Semantic Indexing) to identify lexical similarities between textual contents, and a fuzzy clustering algorithm to form groups of similar web pages. For each page of the website, a set of navigation links towards pages showing similar content and a measure of such similarity is provided. The paper presents the approach to generate SNMs, an implementation for the Joomla! open source WCMS, and the results of an empirical evaluation involving two real world websites built using this WCMS. </jats:p
