An Efficient Object Hierarchy Construction for Viewing Internet Products on Mobile Phones

With the advances of wireless technologies and mobile computing, m-commerce is being realized for many kinds of mobile devices. Service contents for m-commerce are usually newly written to meet specific characteristics of the target mobile devices. To avoid these formidable efforts, it is very important to effectively exploit the Internet merchant information currently served for e-commerce. However, bringing the Internet contents to mobile devices is far from straightforward due to the many limitations of mobile devices such as little memory, small displays, low processing speeds, and so forth. In this paper, assuming that the Internet merchant information is written in XML, we will suggest four methods to construct the object hierarchy for viewing the documents on the mobile phones. We then will compare them by experiment in terms of response times and memory space.
