2007 Second International Workshop on Semantic Media Adaptation and Personalization (SMAP 2007)  
In this paper, a multimedia reasoning architecture is presented using the fuzzy extension of expressive SHIN , f-SHIN .  ...  First a segmentation algorithm generates a set of oversegmented regions and a classification process is employed to assign those regions with semantic labels.  ...  As pointed out in the fuzzy DL literature [11, 10] , fuzzy extensions of DLs involve only the assertion of individuals to concepts and the semantics of the new language.  ...
