Topic models and diversity in video hyperlinking

The use of hierarchical topic models to find anchor-target pairs could potentially improve diversity in video hyperlinking, and the evaluation of video hyperlinking should focus more on assessing serendipity in the links. These are two important findings of the work of Anca-Roxanna Simon who defended successfully her PhD thesis on “Semantic Structuring of Video Collections from Speech: Segmentation and Hyperlinking”, Wednesday 2nd of December at the University of Rennes, France.
