A Content Provider-Specified Web Clipping Approach for Mobile Content Adaptation

In this paper a new mobile content adaptation method based on web clipping is introduced. In this method, a clip is automatically extracted from a source page based on a clip specification provided by a content provider and transformed into a target page according to a set of conversion rules. A new XML-based language, WCML (Web Clipping Markup Language) is defined to store the clips in an intermediate meta-language, which are later transformed into multiple presentation pages in different target markup languages. A clip editing tool is designed and implemented to allow the content provider to easily provide clip specifications and preview and work with the layout of target pages through a graphic user interface. Transcoding of image objects in major image file formats is also supported.
