RESEARCH PROJECTS
DIVINE – Dynamic Integration and Visualization of Information from Multiple Evidence Sources. DIVINE integrates data from structured, unstructured and social sources to build information spaces. Lightweight seed ontologies act as focal points for integrating new evidence from third-party sources. Since such evidence is inherently uncertain, source-specific transformation rules assign confidence values to newly acquired pieces of knowledge.
RAVEN – Relation Analysis and Visualization for Evolving Networks. RAVEN keeps analysts and decision-makers up-to-date about the unfolding of events in endogenous and exogenous information spaces, which reflect interconnected events and processes of the real world. RAVEN aims to understand the evolution of such spaces by analyzing temporal-semantic relations between their elements.
IDIOM – Information Diffusion across Interactive Online Media: Linguists define “idiom” as expression whose meaning is different from the literal meanings of its component words. Similarly, the study of information diffusion promises insights that cannot be inferred from individual network elements. Media monitoring projects often focus on a particular medium, or neglect important aspects of the human language. IDIOM addresses these gaps to reveal fundamental mechanisms of information diffusion across media with distinct interactive characteristics.
AVALON – Acquisition and VALidation of Ontologies: Valuable knowledge that surrounds the workflows of business entities can be extracted automatically and represented as ontological structure. AVALON services build upon a cybernetic control system to automatically align extracted knowledge with business processes, external indicators and individual expertise. Such services are particularly useful in volatile business environments, which require dynamic reconfiguration of business processes and a flexible allocation of resources.
European eContent Tourism Survey. Longitudinal survey on behalf of the Austrian Federal Economic Chamber, which contrasted a sample of 500 Austrian tourism sites with the international competition. Selected results were presented at the European Forum Alpbach in August 2001.
