Using Collectionlinks and Documents as Context for INEX 2008

摘要

We present in this paper the work of the Information Retrieval Modeling Group (MRIM) of the Computer Science Laboratory of Grenoble (LIG) at the INEX 2008 Ad Hoc Track. We study here the use of non structural relations between document elements (doxels) in conjunction with document/doxel structural relationships. The non structural links between doxels of the collection come from the collectionlink doxels. We characterize the non structural relations with relative exhaus-tivity and specificity scores. Results of experiments on the test collection are presented. Our best run is in the top 5 for iP[0.01] values for the Focused Task.
