Texto completoPour s'affranchir des langages ou formats de description multimédia, nous abstrayons les documents en une structure exprimant l'ensemble des relations entre objets du document. Les relations entre objets sont d'ordre temporel, spatial, hypermédia voire inter-dimensionnel, et peuvent être de nature qualitative. Cette structure capture la sémantique des documents car elle est capable de couvrir chacune de ses exécutions potentielles. Dans ce contexte, adapter va consister à calculer un ensemble d'exécutions le plus proche possible de ces exécutions potentielles qui satisfont les contraintes d'adaptation imposées par une plate-forme cible. À cet effet, les relations de la structure abstraite sont modifiées de sorte de satisfaire ces contraintes d'adaptation. Nous montrons, pour chaque dimension du document, comment réaliser ceci de manière réaliste.
Afin de montrer l'applicabilité d'une telle approche, nous la développons dans un cadre adapté au standard SMIL pour lequel nous déclinons les adaptations spatiales, temporelles, spatio-temporelles et hypermédia. Nous sommes amenés à développer des techniques spécifiques pour les représentations spatiales et temporelles efficaces. Nous explorons aussi des approches impliquant la suppression d'objets.

Texto completoA multimedia document combines text, image, sound and video technologies. Currently, multimedia documents may have to be executed on multiple devices such as mobile phones, PDAs, desktop computers, set-top boxes, etc. Hence, usage and platform diversity requires document adaptation according to execution contexts, sometimes unpredictable at design time. We propose to abstract from format specific details by defining a structure which expresses a set of multimedia objects and the relations between them. These relations can be described qualitatively and may be temporal, spatial, hypermedia and spatio-temporal-hypermedia. This document abstraction captures document semantics because it is able to cover all the potential executions of the document. In this context, adapting amounts to find a set of executions as close as possible to potential ones which satisfy adaptation contraints imposed by the target device. For that purpose, the relations contained in the document abstraction are modified in order to satisfy these adaptation constraints. We show how to achieve this convincingly on all the document dimensions. In order to show the applicability of our framework, we implement a prototype which adapts the temporal, spatial and hypermedia dimensions of SMIL documents. We develop specific efficient techniques for the temporal and spatial representations. Moreover, we explored other approaches such as considering multimedia object deletion

Texto completoThis thesis is about to explore the use of tools to support semantics of data in the field of multimedia. The first contribution concerns the generation of high-level descriptions. We propose a description language that allows high-level definition of events and objects from low-level features. The second contribution is the exploration of certain types of uncertainty reasoning in the context of multimedia semantics. We propose a semantic language (based on fuzzy conceptual graphs) for descriptions of videos and define mechanisms underlying reasoning. The third contribution relates to the semantic indexing and retrieval in multimedia databases. We propose a query language from deductive databases for the expression of spatiotemporal and semantic queries

Texto completoRecent research in Deep Learning has sent the quality of results in multimedia tasks rocketing: thanks to new big datasets of annotated images and videos, Deep Neural Networks (DNN) have outperformed other models in most cases. In this thesis, we aim at developing DNN models for automatically deriving semantic representations of images and videos. In particular we focus on two main tasks : vision-text matching and image/video automatic captioning. Addressing the matching task can be done by comparing visual objects and texts in a visual space, a textual space or a multimodal space. Based on recent works on capsule networks, we define two novel models to address the vision-text matching problem: Recurrent Capsule Networks and Gated Recurrent Capsules. In image and video captioning, we have to tackle a challenging task where a visual object has to be analyzed, and translated into a textual description in natural language. For that purpose, we propose two novel curriculum learning methods. Moreover regarding video captioning, analyzing videos requires not only to parse still images, but also to draw correspondences through time. We propose a novel Learned Spatio-Temporal Adaptive Pooling method for video captioning that combines spatial and temporal analysis. Extensive experiments on standard datasets assess the interest of our models and methods with respect to existing works
Harrando, Ismail. "Representation, information extraction, and summarization for automatic multimedia understanding". Electronic Thesis or Diss., Sorbonne université, 2022. http://www.theses.fr/2022SORUS097.
Texto completoWhether on TV or on the internet, video content production is seeing an unprecedented rise. Not only is video the dominant medium for entertainment purposes, but it is also reckoned to be the future of education, information and leisure. Nevertheless, the traditional paradigm for multimedia management proves to be incapable of keeping pace with the scale brought about by the sheer volume of content created every day across the disparate distribution channels. Thus, routine tasks like archiving, editing, content organization and retrieval by multimedia creators become prohibitively costly. On the user side, too, the amount of multimedia content pumped daily can be simply overwhelming; the need for shorter and more personalized content has never been more pronounced. To advance the state of the art on both fronts, a certain level of multimedia understanding has to be achieved by our computers. In this research thesis, we aim to go about the multiple challenges facing automatic media content processing and analysis, mainly gearing our exploration to three axes: 1. Representing multimedia: With all its richness and variety, modeling and representing multimedia content can be a challenge in itself. 2. Describing multimedia: The textual component of multimedia can be capitalized on to generate high-level descriptors, or annotations, for the content at hand. 3. Summarizing multimedia: we investigate the possibility of extracting highlights from media content, both for narrative-focused summarization and for maximising memorability

Texto completoContext-awareness qualifies computing systems which seek to adapt their overall behavior to a set of information, called the context of use. In spite of their heterogeneity, the continuous evolution of mobile devices (MD) towards multipurpose, multi-sensors,a nd Web-enabled devices, transforms them into the ideal environment for context-aware applications. MDs are becoming, thanks to their popularity, the main tool for creating personal multimedia documents (PMD). In this new scenario, high level context information can also play an important role. In fact, information related to the context in which the document was capture or created can offer information rich enough to describe, and, thereafter, identify such documents. This work addresses the intersection of two research domains : Context-aware Computing and Multimedia Management. Context-awareness in the management of PMD is a new research approach, where the proposition of semantic models for representing contextual information and of mechanisms for acquiring and exploiting the high-level information are still unsolved problems. We propose a new context-aware architecture for the management of PMD called CoMMediA (Context-aware Mobile Multimedia Architecture) which is inspired by frameworks oriented to the adaptation of Mobile Information Systems. Our contributions consists of : I) a semantic model for representing multimedia metadata (Context Multimedia), described in OWL and following a new notion of context, II) an adaptative middleware for context acquisition and multimedia creation (called DevAC), which takes into account the heterogeneity and the intrinsic limitations of MDs during the deployment of mobile applications, and III) a platform that enriches contextual metadata (ContextAnnotator). Our objective is to promote the automatic production of metadata, and also to propose mechanisms for the integrating this high-level and semantic metadata in the processes of organization, annotation, sharing, and keyword-based retrieval of DMP. Moreover, DevAC and our mobile applications of DMP management are based on a component middleware and a semantic description of services. The ultimate goal is to assist developers in the development and deployment of multimedia and context-aware applications which can be adapted according to the models of users' MDs, without the need to rewrite their code
Guerry, Michèle. "La représentation sémantique des verbes d'attitude propositionnelle". Poitiers, 1994. http://www.theses.fr/1994POIT5022.
Texto completoThe object of this research is to study the semantic representation of some epistemic modality markers; i. E. Mental verbs. It aims at: 1) characterizing the main dimensions of the semantic field of those verbs, 2) assessing the psychological relevance of a mental model partitioned into spaces and integrating the "belief spaces". A first set of tests (classification according to the similarity principle, assessment of the degree of certainty and probability), makes it possible to bring forth two main aspects: - the first concerns the degree of certainty of the speakers's utterance, - the second one concerns the source of the assertion. Besides, the results of the experiments show that, even though the relative degree of certainty associated with the various mental verbs constitutes a relatively stable scale, its absolute value is sensitive to "contextual" parameters linked to the source of the assertion. A second group of tests (valuation of recognition times) shows a functional difference between various representation sets (reality space of the speaker, "belief space" of another speaker). Moreover, a variation in the recognition timess depending on the degree of probability endorsed by the verb, can be noted within a "belief space" attributed to another speaker. The theoretical implications of the results are discussed with relation to the different models of semantic representation

Texto completoMultimedia data sources from various fields (medical, tourism, trade, art and culture, etc.) became essential on the web. Accessing to multimedia data in distributed systems poses new challenges due to many system parameters: volume, diversity of interfaces, representation format, location, etc. In addition, the growing needs of users and applications to incorporate semantics in the information retrieval pose new issues. To take into account this new complexity, we are interested in our research of data integration solutions based on web services. In this thesis, we propose an approach-oriented service for the semantic search of multimedia content. We called this approach SeSaM (Semantic Search of Multimedia content). SeSaM is based on the definition of a new pattern of services to access multimedia content, which is the MaaS services (Multimedia as a Services). It is based on a two-phase process: description and discovery of MaaS services. As for the MaaS services description, we have defined the SA4MaaS language (Semantic Annotation for MaaS services), which is an extension of SAWSDL (W3C recommendation). The main idea of this language is the integration, in addition to business domain semantic, of multimedia information semantics in the MaaS services description. As for the MaaS service discovery, we have proposed a new matchmaker MaaS-MX (MaaS services Matchmaker) adapted to the MaaS services description model. MaaS-MX is composed of two essential steps: domain matching and multimedia matching. Domain matching consists in comparing the business domain description of MaaS services and the query, whereas multimedia matching compares the multimedia description of MaaS services and the query. The approach has been implemented and evaluated in two different domains: medical and tourism. The results indicate that using both domain and multimedia matching considerably improves the performance of multimedia data retrieving systems
