2007 International Workshop on Content-Based Multimedia Indexing, 2007•ieeexplore.ieee.orgThe Semantic Gap is considered to be a bottleneck in image and video retrieval. One way to
increase the communication between user and system is to take advantage of the user's
action with a system, eg 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. The assumptions on
which this model was created are then analysed in an experiment using simulated users …

The Semantic Gap is considered to be a bottleneck in image and video retrieval. 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. The assumptions on which this model was created are then analysed in an experiment using simulated users based on relevance judgements to compare results of explicit and implicit retrieval cycles. Our model seems to enhance retrieval results. Results are presented and discussed in the final section.
