Based on this observation, we present a new viewpoint to perform semantic movie analysis. Through checking the co-occurrence of roles in different scenes, we construct a roles' social network to describe their relationships. We introduce the concept of social network analysis to elaborately identify leading roles and the hidden communities. With the results of community identification, we perform storyline detection that facilitates more flexible movie browsing and higher-level movie analysis. The experimental results show that the proposed community identification method is accurate and is robust to errors. ©2007 IEEE.en-USSemantics; Co-occurrence; Community identification; Movie analysis; Movie understanding; Storylines; Motion picturesconference paper10.1109/ICME.2007.42849222-s2.0-38049042317http://ntur.lib.ntu.edu.tw/bitstream/246246/220320/-1/16.pdf
