%T IMKA: A Multimedia 		Organization System Combining Perceptual and Semantic Knowledge
%B ACM Multimedia
%C Ottawa, Cananda
%X In this demo, we present the IMKA system, which 		 implements the innovative approach of integrating perceptual 			 information such as low-level features and images, and symbolic 			 information such as words to represent the knowledge associated 			 with a large multimedia collection for multimedia organization and 			 retrieval. The IMKA system utilizes the unique MediaNet framework, 		 which greatly extends existing knowledge representation tools in 			 the text domain (e.g., semantic networks and WordNet) and the 			 multimedia domain (e.g., Multimedia Thesaurus) by combining 			 perceptual and semantic concepts in the same network and by 			 supporting perceptual and semantic relationships among concepts 			 exemplified by different media. It also brings the level of 			 multimedia retrieval closer to users needs by translating 			 low-level feature queries to high-level semantic queries and vice 			 versa. We will demonstrate the process of constructing the 			 MediaNet knowledge base and new ways of searching multimedia in 			 the IMKA system by presenting the current implementation of the 			 IMKA system that uses image collections from online sources.
