Guest Editors' Introduction: Multimedia Metadata and Semantic Management
2009
This special issue assesses the current status and technologies and describes major challenges and proper solutions for effective multimedia production and management related to evolving Semantic Web strategies. The included articles, which cover different facets of the semantic management of multimedia and multimedia metadata from retrieval and processing to consumption and presentation, represent a step forward in research targeted at improving aspects of the semantic metadata life cycle.
Towards a Novel Approach to Multimedia Data Mixed Fragmentation
2009
International audience; Distributed multimedia applications have emerged at an increasing rate during the last decade in several domains (video conferencing, e-health, virtual meeting rooms, etc). This has created several new challenging problems related to the data integration and fragmentation, user-oriented and adaptive interfaces, real time and network performances, etc. In this paper, we focus on the problem of data(base) fragmentation in a multimedia context. We recall in this respect that data fragmentation consists of reducing irrelevant data accesses by grouping data frequently accessed together in dedicated segments. We mainly address the issue of query and predicate implication r…
Detecting Inference Channels in Private Multimedia Data via Social Networks
2009
International audience; Indirect access to protected information has been one of the key challenges facing the international community for the last decade. Providing techniques to control direct access to sensitive information remain insufficient against inference channels established when legitimate data reveal classified facts hidden from unauthorized users. Several techniques have been proposed in the literature to meet indirect access prevention. However, those addressing the inference problem when involving multimedia objects (images, audio, video, etc.) remain few and hold several drawbacks. In essence, the complex structure of multimedia objects makes the fact of detecting indirect a…
Automatic Temporal Formatting of Multimedia Presentations Using Dynamic Petri Nets.
2009
An efficient authoring tool would provide support for automatic temporal formatting and modeling of multimedia presentations. Automatic temporal formatting is a process of converting the given presentation specifications into a required temporal format. This paper presents an algorithm that can convert a temporal layout into a dynamic petri net (DPN )w hich can represent iterative and interactive presentation components effectively. The prototype of the authoring tool extracts the temporal layout from any given SMIL file representation and uses the proposed algorithm to automatically convert it into a DPN. The DPN generated automatically at compile-time helps the run-time components in effe…
Semantic aware RSS query algebra
2010
International audience; Existing XML query algebras are not fully appropriate to retrieve RSS news items mainly due to three reasons: 1) RSS is text rich and its content is dependent on the wording and verbification of the author, thus semantic aware operators are needed; 2) news items are dynamic and consequently time oriented retrieval is needed; 3) a news item may evolve through time, or overlap with other news items and hence identifying relationships between items is also needed. In this paper, we aim to solve these issues by providing a dedicated RSS algebra based on semantic-aware operators that consider RSS characteristics. The provided operators are application domain specific and …
Implicit motor learning in discrete and continuous tasks: Toward a possible explanation of discrepant results

Abstract
Why elevator trips are comparable to piano lessons and not to pet-sitting: world semantics guiding analogies between arithmetic word problems
2017
DOI: 10.13140/RG.2.2.35896.65284, document consultable : https://www.researchgate.net/publication/318672689; International audience; Arithmetic word problems of analogous objective mathematical structure can lead to dramatically different success rates depending on their wording (Hudson, 1983), and transfer between problems can be significantly favored or hindered by the cover stories used (Bassok, Wu & Olseth, 1995). But what promotes the perception of the analogy between different wordings of a same problem? Previous works have hinted at the existence of abstract semantic dimensions stemming from the solvers’ knowledge about the world and influencing the encoding and solving of problem st…

Homme et animal, la question des frontières.
2009
214 pages; Certains arguments permettent aujourd'hui de réévaluer la thèse de la singularité de l'homme. Du point de vue de l'identité psychologique et des performances cognitives, la différence entre les grands singes et l'homme ne serait pas de nature mais seulement de degrés. La biologie considère également les distinctions homme/animaux comme des différences dans la nature, et non entre nature et culture. Au plan éthique, les formes d'appropriation des animaux ont conduit à les instrumentaliser. À cela s'ajoutent les menaces sur les espèces sauvages dues au développement industriel. Certains admettent ainsi une véritable solidarité d'ordre moral ou juridique entre les formes de vie huma…
