DEBII Seminar by Prof. Arno Scharl on "Relation Analysis and Visualization for Evolving Networks (RAVEN)"


The Digital Ecosystems and Business Intelligence Institute (DEBII) is pleased to invite you to a presentation by Prof. Arno Scharl, Vice President of MODUL University Vienna and Head of the Department of New Media Technology on "Relation Analysis and Visualization for Evolving Networks (RAVEN)".


Professor Arno Scharl
Date: Tuesday, 2nd Feb 2010
Time: 11 am
Location: "Workplace Room", Enterprise Unit 3, Techpark, Bentley

Presentation Outline

This presentation summarizes the lessons learnt from the RAVEN project (01/2008 to 06/2010), which aims to determine trends in the frequency and sentiment of tokens, terms and concepts within composite information spaces built from endogenous and exogenous sources. RAVEN annotates information objects to control data flows or backup priorities within an organization, for example, or to track media coverage on a recently launched product line. Ambiguity and subtle incremental changes of tonal expressions between different versions of a document complicate this process.
Animated visualizations of temporal-semantic relations will help analysts comprehend and utilize very large data sets comprising millions of documents. A Javascript framework embeds temporal controls into ensembles of tightly coupled views in multiple-screen setups. RAVEN will use this framework to investigate the benefits of spherical geometries for user interface design, and provide add-on components to use virtual globes as generic image rendering engines for various types of data.
