johannes p osterhoff - CONTENTUS

My esteemed collegues Harald Sack, Jörg Waitelonis and I wrote a paper about our recent project CONTENTUS, the semantic multimedia retrieval system.

We stressed the “browsing” capabilites of its user interface and its multi-modal presentation of search results.
The paper present the semantic search engine CONTENTUS and its user interface, a multimedia retrieval system developed in the context of the German research project THESEUS. This interface uses content-based suggestions and a multi-modal presentation of search results to support semantic search. In addition, the system deploys a combination of a facetted browsing and breadcrumb-based navigation; a time-line enables time based filtering of the search results and the system suggests related search results according to the user’s preferences. Finally, CONTENTUS has become more than the sum of its parts. Its unique feature combination facilitates search to become a more efficient and overall more pleasant user experience.

When showing various media types on one result page, special care has to be devoted to the feedback that lets the user know why exactly the listed items have been presented. To find an appropriate balance between the demand for details on the one hand and ease of use on the other hand is subject to further research on CONTENTEUS.

The paper was accepted at the workshop VISSW 2011 Visual Interfaces to the Social and Semantic Web held in conjunction with the International Conference on Intelligent User Interfaces (IUI 2011) in Palo Alto.
