Toward Mining of Temporal Roles
[chapter]

Lecture Notes in Computer Science

First we formally define the Temporal Role Mining Problem (TRMP), and then show that the TRMP problem is NP-complete and present a heuristic approach for solving it. ...
Existing role mining techniques, however, cannot be used to process the temporal element associated with roles in these models. ...

Current video mining systems face the problem of the semantic gap (i.e., the difference between the semantic meaning of video contents and the digital information encoded within the video files). ...
We think that the introduction of semantics during these steps can be ensured by user interaction. We then propose a generic framework to deal with video object mining. ...
