Mobile Web Navigation in Digital Ecosystems Using Rooted Directed Trees

Due to advances in techniques for digital ecosystems and cyber engineering, users can now submit queries to search for inclusive information from different Web objects using mobile handheld devices such as smartphones in many real-life situations. As these mobile devices are not necessarily connected to the Internet all the time, users usually want to be able to get information such as e-mail, news, weather, and Web feed as soon as their mobile devices are connected to the Internet. However, these mobile devices have relatively limited resources. In this paper, we focus on mobile web navigation. Specifically, we use rooted directed trees, which enable users to access valuable information from the highly ranked and relevant Web sites, for answering user-inclusive queries.
