This paper describes our participation in the ImagePhoto task at CLEF 2008. We present the joint work of two teams belonging to the TEXT-MESS project using a new system that combines the individual systems of these teams, one based on filtering and the other one based on clustering. We have submited experiments using SINAI filtering method with the IR-n output, and the IR-n clustering module with the SINAI output. Our objective was to study the behaviour of these methods with a large number of

The results show that a filtering method is not useful when we use the cluster terms or related words to filter retrieved documents, and that a clustering method can improve the results of cluster detection although at the expense of a decrease in precision of the results that is greater than the gain obtained for the CR20 measure with this method.
