APA Labs: An experimental web-based platform for the retrieval and analysis of news articles

In this paper, we present APA Labs, an experimental, Web-based platform supporting retrieval and analysis in the news archives of the Austrian Press Agency. APA Labs has been designed as a combination of a rich internet application with a modular system of interactive visualizations backed by server-side entity extraction and three-dimensional rendering capability. This paper outlines concepts and implementation details of APA Labs and presents several visualization modules based on research results from the field of Information and Knowledge visualization.
