DCU Linking Runs at MediaEval 2013: Search and Hyperlinking Task

All measures, except the MAP-tol measure, are notably higher in the experiments in which we did not remove par- tially overlapping segments from the list of the retrieved segments..

For our participation in the Hyperlinking sub-task of Search and Hyperlinking of Television Content in MediaEval 2014, we developed a new strategy of target segment determina-

The calculated V isualSimilarity was used to modify the final score of the segment in the retrieval for a particular query segment as follows (the W eight parameter was tuned on

Given the fact that the baseline system can be beaten on the training set, results over the test set suggest that models optimised on MRR, mGAP, and MASP for a known-item

The Search and Hyperlinking Task at MediaEval 2013 envisioned the following scenario: a user is searching for a segment of video that they know to be contained in a video

The retrieved keyframes associated with an anchor require a further processing to generate a ranked list of temporal video segments.. Our approach is based on the assumption that

• part-sc-C: Partial scenes search from shot boundary using textual and visual cues following three steps: filtering of the list of videos; querying for shots inside each video;

For search, we compute word- based similarity (from transcript and metadata) between queries and all segments in the collection, using a vector space model based and TF-IDF
