XFIRM at INEX 2006. Ad-Hoc, Relevance Feedback and MultiMedia Tracks [chapter]

Lobna Hlaoua, Mouna Torjmen, Karen Pinel-Sauvagnat, Mohand Boughanem
Lecture Notes in Computer Science  
Runs were submitted to the ad-hoc, relevance feedback and multimedia tracks.  ...  This paper describes experiments carried out with the XFIRM system in the INEX 2006 framework. The XFIRM system uses a relevance propagation method to answer CO and CO+S queries.  ...  Introduction In this paper, we decribe the IRIT/SIG-RFI participation in the INEX 2006 ad-hoc, relevance feedback and multimedia tracks.  ...

The Wikipedia Image Retrieval Task [chapter]

Theodora Tsikrika, Jana Kludas
2010 ImageCLEF  
The Wikipedia image retrieval task at ImageCLEF provides a test-bed for the system-oriented evaluation of visual information retrieval from a collection of Wikipedia images.  ...  The aim is to investigate the effectiveness of retrieval approaches that exploit textual and visual evidence in the context of a large and heterogeneous collection of images that are searched for by users  ...  track, Thomas Deselaers for invaluable technical support during ImageCLEF 2008, and all the groups that participated in the task and in the relevance assessment process.  ...

A survey on tree matching and XML retrieval

Mohammed Amin Tahraoui, Karen Pinel-Sauvagnat, Cyril Laitang, Mohand Boughanem, Hamamache Kheddouci, Lei Ning
2013 Computer Science Review  
In this paper, we aim at studying the theoretical approaches proposed in the literature for tree matching and at seeing how these approaches have been adapted to XML querying and retrieval, from both an  ...  exact and an approximate matching perspective.  ...  Structure-oriented approaches can still be evaluated with the ad hoc track, but since 2006, structure interest is no more a research priority for the ad hoc track organizers.  ...
