Adaptive WAP Portal

摘要

Mobile Internet browsing using WAP phones has created unique problems of its kind. One of the challenges that consumers faced is that they are only equipped with a small screen for browsing WAP contents. This makes navigating to WAP sites of interest on WAP portals a hassle. WAP portals served as consumers' gateway to the WAP sites offered by third party content providers. These portals usually organize the list of WAP sites into a multi-level tree hierarchy structure. Consumers are required to navigate deep down the tree to access their favorite sites. This paper proposes methods for making WAP portals adaptive. Such portals reduce time spend by consumers in navigation henceforth more time for content browsing. The proposed methods do not require explicit consumers' input for adaptation but rather, they implicitly track consumers' navigation activities among WAP sites and use these input to form the basis of consumers' preferences for adaptation. The methods had also taken into account possible drift of consumers' interest over time and weighted computation is used to achieve adaptation that will be of relevance to consumers at any point of time. Preliminary experiments with mobile users have yield promising results.
