Interacting Annotations in MADCOW 2.0

MADCOW 2.0 is a system for annotation of Web content, supporting the production and exploration of personal and public annotations on text, images and videos in aWeb page. Its design starts from the main requirement that the annotation activity does not have to disrupt the normal browsing of Web pages by a user. MADCOW 2.0 allows interaction with the annotated portions of the page to provide access to the annotation content. Conversely, the representation of the existing notes supports different forms of exploration of the Web page, and can become the starting point for further navigation over the Web. A uniform style of interaction has been adopted for creating and accessing annotations on text, images and videos, and some novel solutions have been introduced to cope with overlaps between the annotated portions. The annotation user experience is facilitated by enabling forms of in-place annotation and manipulation of both the annotated portion and the annotation content. Copyright © 2010 ACM.
