Description

This project funded by the Federal Commission for Technology and Innovation (KTI no. 12747) joins an interdisciplinary team of researchers from the University of St. Gallen, the Zurich University of Applied Sciences, and the University of Zurich (Institute of Biomedical Ethics & Department of Geography) together with a business partner Atizio (AG), an internet start-up company. The project goal is the development of novel online text data mining methods coupled with innovative information visualization displays for the effective and efficient exploration of rapidly growing online text data bases generated through crowd sourcing and virtual idea brainstorming platforms.

The core algorithm allows for a semantic analysis in a growing text space on the basis of a self-learning neural network.
