“…An audio segment related to a text segment by a long overlap might, for instance, be regarded as more relevant with respect to the content of the text than another audio segment related to the text by a meet relation. An empirical investigation of the space of temporal relations along the lines of the strategy proposed in [20] might be useful in this context.…”

Abstract. This paper presents an approach to the issue of adding structure to recordings of collaborative meetings supported by an audio channel and a shared text editor. The virtual meeting environment used is capable of capturing and broadcasting speech, gestures and editing operations in real-time, so recording results in continuous multimedia data. We describe the implementation of a browser which explores simple linkage patterns between these media to support information retrieval through non-linear browsing, and discuss audio segmentation issues arising from this approach.

“…The study of temporal relations between elements of a process is a very active topic of research, with a wide range of applications: biomedical informatics [5,20], law [17], media [2,4,8] etc. Temporal reasoning enables to analyze the content of a document in order to infer high-level information.…”

Abstract. This paper is originally motivated by an application where the objective is to generate a video summary, built using intervals extracted from a video source. In this application, the constraints used to select the relevant pieces of intervals are based on Allen's algebra. The best state-of-the-art results are obtained with a small set of ad hoc solution techniques, each specific to one combination of the 13 Allen's relations. Such techniques require some expertise in Constraint Programming. This is a critical issue for video specialists. In this paper, we design a generic constraint, dedicated to a class of temporal problems that covers this case study, among others. ExistAllen takes as arguments a vector of tasks, a set of disjoint intervals and any of the 2 13 combinations of Allen's relations. ExistAllen holds if and only if the tasks are ordered according to their indexes and for any task at least one relation is satisfied, between the task and at least one interval. We design a propagator that achieves bound-consistency in O(n + m), where n is the number of tasks and m the number of intervals. This propagator is suited to any combination of Allen's relations, without any specific tuning. Therefore, using our framework does not require a strong expertise in Constraint Programming. The experiments, performed on real data, confirm the relevance of our approach.
