Projects

Visualisation of Semantic Graphs

COMET project 2012

The project partner m2n operates with large semantic graphs (Ontologies) and therefor needs an intuitive, scalable Web-based visualization component supporting interactive navigation and exploration of such graphs. Within the project a detailed user requirement survey is performed together with m2n. Based on the user requirements a flexible Web-based Software architecture…

Semantic Network Analysis in Large Heterogeneous Repositories

COMET project 2010

The goal of this project, which is performed in cooperation with m2n, is to enable the retrieval, analysis and visualisation of large, heterogeneous, strongly interlinked data repositories. To achieve this, extraction methods were developed which, under consideration of existing knowledge bases, enable semantic enrichment of large heterogeneous data sets. Using…

Topic Seismograph

COMET project 2010

The User Generated Content (UGC) Seismograph project aimed to provide for Kabel TV Wien, a local information provider, a pilot system for analysis of UGC with regional focus. Within the project a number of Web sources, such as Standard Online and ORF Online, have been crawled and analyzed, whereby the…

Service Oriented Architectures for Navigation and Search in heterogeneous Repositories

COMET project 2009

The goal of this project is the development of visual tools and maintainance of the KD-Service webservice. Based on the existing KD-Service framework a client application has been developed which allows a user to interact with a series of visualisations of textual documents. To achieve this, the existing Knowledge Discovery…

Gyro- 3D Knowledge Web Visualisation

Kplus project 2004

"Der Brockhaus" is probably the most famous german encyclopaedia. In its multimedia edition, it offers recherche in 240.000 articles for 320.000 keywords. Information types include images and audio files as well as videos, animations, geographical data and many more. A knowledge web can be displayed for each encyclopaedia entry, showing…

InfoSky: Visualisation of Hierarchical Knowledge Spaces

Kplus project 2002

Employing today’s standard means of navigation and visualisation for large knowledge spaces, the identification of trends, relations and similarities between documents or search results is no trivial task. Knowledge Management Systems add to the problem by structuring documents in hierarchies, which are even less suited for explorative analysis in standard…

WebRat- Interactive Visualisation and Analysis of Web Queries

Kplus project 2002

In the "WebRat" project we have combined the know-how and the exepriences acquired in other projects in the domain of Knowledge Retieval and Knowledge Visualisation to create a prototype tool for performing and refining Web search queries and and interactively visualising the result set. The retrieval and visualisation framework we…

Visualisation of Hierarchical Knowledge Spaces

Kplus project 2001

The “InfoSky” project dealt with design and implementation of a system for interactive search and navigation in very large, hierarchically structured knowledge spaces. The metaphor of the information galaxy, where documents are represented as stars, groups of topically similar documents are represented as clusters of stars and hierarchical entities are…
