Project Summary:

The retrieval and marketability of visual content highly depends on the availability of high quality image meta data which enables customers to efficiently locate relevant content in large image collections.


The IMAGINE project develops advanced information extraction methods which exploit the convergence between textual image descriptions and image content as well as linked open data to automatically obtain relevant meta data such as keywords, named entities and topics.


Project consortium

The IMAGINE project is funded by the Swiss Federal Department of Economic Affairs' (FDEA) Commission for Technology and Innovation (CTI).

The project partners include the University of Applied Sciences Chur (Institute for Information Research), and the KEYSTONE AG Zurich, the Swiss provider with the most comprehensive offer of visual content – photography, graphics, video.
