Progressive Content Delivery for Mobile E-Services
- In this paper we present a framework for the progressive delivery of Web documents in mobile Internet services.

The central part of the delivery consists of innovative concepts for content selection to determine the most relevant document parts for successive delivery maintaining the documents' readability. To make this selection as flexible and effective as possible we consider the user's notion of relevance together with semantic author annotations and structural document characteristics.
