The multimedia content delivery chain poses today many challenges. The increasing terminal diversity, network heterogeneity and the pressure to satisfy the user preferences are raising the need for content to be customized in order to provide the user the best possible experience. This paper addresses the problem of multimedia customization by (1)(More)
We describe our experiments for the shot boundary detection, high-level feature extraction , search and story boundary detection tasks. In the shot boundary detection task, we employ our proven method based on the calculation of distances between colour histograms of frames over a range of timescales. In the feature detection task we confined our effort to(More)
In this paper we describe the geographic information retrieval system developed and results achieved by the Multimedia & Information Systems team for GeoCLEF 2006. We detail our methods for generating and applying co-occurrence models for the purpose of place name disambiguation, our use of named entity recognition tools and text indexing applications. The(More)
This paper describes the participation of the NovaSearch group at TREC Clinical Decision Support 2014. As this is the first edition of the track, we decided to assess the performance of multiple information retrieval techniques: retrieval functions, re-ranking, query expansion and classification of medical articles into question categories. The best(More)
We propose a novel algorithm for extracting information by mining the feature space clusters and then assigning salient concepts to them. Bayesian techniques for extracting concepts from multimedia usually suffer either from lack of data or from too complex concepts to be represented by a single statistical model. An incremental information extraction(More)
This paper details an integrated methodology to optimise Knowledge reuse and sharing, illustrated with a use case in the aeronautics domain. It uses Ontologies as a central modelling strategy for the Capture of Knowledge from legacy documents via automated means, or directly in systems interfacing with Knowledge workers, via user-defined, web-based forms.(More)
We all had the problem of forgetting about what we just read a few sentences before. This comes from the problem of attention and is more common with children and elderly. People feel either bored or distracted by something more interesting. This paper proposes an application to help people reading news by illustrating the news story. The application(More)
