MEDIAEVAL 2014, MediaEval Benchmarking Initiative for Multimedia Evaluation Workshop, October 16-17, 2014, Barcelona, Spain
The paper presents the LinkedTV approaches for the Search and Hyperlinking (S&H) task at MediaEval 2014. Our submissions aim at evaluating 2 key dimensions: temporal gran-
ularity and visual properties of the video segments. The temporal granularity of target video segments is de ned by grouping text sentences, or consecutive automatically de-
tected shots, considering the temporal coherence, the visual similarity and the lexical cohesion among them. Visual properties are combined with text search results using mul-
timodal fusion for re-ranking. Two alternative methods are proposed to identify which visual concepts are relevant to each query: using WordNet similarity or Google Image analysis. For Hyperlinking, relevant visual concepts are identi ed by analysing the video anchor.
