Simulated Testing of an Adaptive Multimedia Information Retrieval System

Frank Hopfgartner, Jana Urban, Robert Villa, Joemon Jose
2007 2007 International Workshop on Content-Based Multimedia Indexing  
One way to increase the communication between user and system is to take advantage of the user's action with a system, e.g. to infer the relevance or otherwise of a video shot viewed by the user.  ...  In this paper we introduce a novel video retrieval system and propose a model of implicit information for interpreting the user's actions with the interface.  ...  It is the view of the authors but not necessarily the view of the communities.  ...
