Annotation-Based Web Content Transcoding

Users are increasingly accessing the Internet from information appliances
such as PDAs, cell phones, and set-top boxes. Since these devices do not
have the same rendering capabilities as desktop computers, it is necessary
for Web content to be adapted, or transcoded, for proper presentation on
a variety of client devices. In this paper, we propose an annotation-based
system for Web content transcoding.
First, we introduce a framework of external annotation, in which existing
Web documents are associated with content adaptation hints as separate
annotation files. We then explain an annotation-based transcoding system
with particular focus on the authoring-time integration between a WYSIWYG
annotation tool and a transcoding module. Finally, after giving an
example of content adaptation using a page fragmentation module for
small-screen devices, we compare our approach with related work.
