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. Progressive delivery enables users to get fast access to the most relevant parts of a document. Given the reduced bandwidth and the high costs of mobile communication the idea of progressive delivery offers a promising improvement especially for mobile e-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. Using XML technology documents are automatically adapted to fit both personal user profiles and device constraints. A prototypical mobile news service exemplifies our approach to content selection, but our framework promises to be applicable to a broad range of future Internet services
