The Interaction Between Automatic Annotation and Query Expansion: a Retrieval Experiment on a Large Cultural Heritage Archive

Véronique Malaisé, Laura Hollink, Luit Gazendam
2008 Extended Semantic Web Conference  
Improving a search system for large audiovisual archives can be done in two ways: by enriching the annotations, or by enriching the query mechanism.  ...  Both operations possibly benefit from a preliminary terminological enrichment of the controlled vocabulary in use, i.e. the thesaurus.  ...  Acknowledgements This project was done in the context of the CHOICE and MUNCH projects, both part the NWO CATCH program.  ...

The TIB|AV Portal as a Future Linked Media Ecosystem

Paloma Marín Arraiza, Sven Strobel
2015 Proceedings of the 24th International Conference on World Wide Web - WWW '15 Companion  
The segment identification and ontology annotation make the portal a good platform to support the Linked Data and Media. Weaving into a machine-readable metadata format will complete this task.  ...  Various techniques for video analysis, concept mapping, semantic search and metadata management are part of the current features of the TIB|AV Portal as described in this demo.  ...  Therefore, our current projects aim to improve the semantic enrichment of the data so that they can be better explored and reused.  ...

The Importance of being Grid: Chemnitz University of Technology at Grid@CLEF

Maximilian Eibl, Jens Kürsten
2009 Conference and Labs of the Evaluation Forum  
For each language we used two different stemmers and two different retrieval models. One run one was a fusion run combining the results of the four other experiments.  ...  Whereas the different runs demonstrated that the impact of the used retrieval technologies is highly depending on the corpus, the merged approach produced the best results in each language.  ...  This work was partially accomplished in conjunction with the project sachsMedia, which is funded by the Unternehmen Region-program 9 of the German Federal Ministry of Education and Research 10 .  ...
