0:52 Outline of the talk
1:26 When the result of a clustering displays a chronological signal: some context
5:24 2 criteria to evaluate the consistency between a tree and a chronological order
5:38 A first criterion: the minimum number of leaves to delete
6:32 A second criterion: the number of conflicts
8:10 The two criteria are not equivalent
9:25 Finding the optimal order for each criterion
11:01 Evaluating the significance of the obtained results
11:59 Perspectives and conclusion
