【 摘 要 】

We describe the runs for our participation in the Search sub-task of the Search and Hyperlinking Task at MediaEval 2012. Our runs are designed to form a retrieval baseline by using time-based segmentation of audio transcripts incorporating pause information and a sliding window to define the retrieval segments boundaries with a standard language modelling information retrieval strategy. Using this baseline system runs based on transcripts provided by LIUM were better for all evaluation metrics, than those using transcripts provided by LIMSI.Categories and Subject DescriptorsH.3.1 [Information Storage and Retrieval]: Content Analysis and Indexing–Indexing methodsGeneral TermsMeasurement, Performance
