Information Delivery for Mobile Business: Architecture for Accessing Large Documents through Mobile Devices

In this information-centric age, an organization needs to access the most update and accurate information for fast decision making. Mobile access to Internet provides convenient and portable access to a huge information space. However, loading and visualizing large documents on mobile devices is impossible due to their natural shortcomings such as screen size and computing power. In this chapter, we introduce the fractal summarization model, based on fractal theory, for document summarization on mobile devices. This model generates a brief skeleton of summary at the first stage, and the details of the summary on different levels of the document are generated on demands from users. Such interactive summarization reduces the computation load, which is ideal for wireless access. On the other hand, the hierarchical display in fractal summarization is more suitable for navigation of a large document and it is ideal for small area display. The automatic summarization together with the three-tier architecture and the information visualization are potential solutions to the existing problems in information delivery to mobile devices for mobile business.
