Scalable Annotation Mechanisms for Digital Content Aggregation and Context-Aware Authoring

Abstract

This paper discusses the role of context information in
building the next generation of human-centered information
systems, and classifies the various aspects of contextualization
with a special emphasis on the production and consumption of digital content.
The real-time annotation of
resources is a crucial element when moving from content
aggregators (which process third-party digital content) to
context-aware visual authoring environments (which allow
users to create and edit their own documents). We present a
publicly available prototype of such an environment, which
required a major redesign of an existing Web intelligence
and media monitoring framework to provide real-time data
services and synchronize the text editor with the frontend’s
visual components. The paper concludes with a summary of
achieved results and an outlook on possible future research
avenues including multi-user support and the visualization
of document evolution.
