Abstract
AbstractOne of the main differences between Spoken Document Retrieval (SDR) systems and Text Retrieval systems is the need of a segmentation process that detects the story boundaries. However, until now, SDR researchers have not paid attention in building correct segments more than considering slidding windows of a fixed size in time. In this paper, new methodology for evaluating segments to SDR task, and the evaluation of three possible strategies are presented over the TREC-9 SDR collection. Moreover, the justification of each strategy is discussed.
