Automatic Adaptation of Multimedia Documents

Alti Adel, Sébastien Laborie, Philippe Roose
2013 Procedia Computer Science  
Currently, multimedia documents can be displayed on multiple platforms (laptops, smartphones, tablets, etc.), that resulting in a birth of new information system called pervasive. The various execution contexts of a multimedia presentation introduce different constraints for the presentation itself. In this paper, we propose a specific ontology for on-the-fly (runtime) adaptation of multimedia documents. More precisely, we propose semantic rules allowing the automatic generation of dynamic and
more » ... uality composition of heterogeneous components. Our proposed ontology has the great advantage to offer to users a flexible infrastructure in order to easily govern the response time and the quality assembly of their own applications at runtime.

Spatio-temporal Proximities for Multimedia Document Adaptation [chapter]

Sébastien Laborie
2006 Lecture Notes in Computer Science  
The multiplication of execution contexts for multimedia documents requires the adaptation of document specifications. This paper instantiates our previous semantic approach for multimedia document adaptation to the spatial dimension of multimedia documents. Our goal is to find a qualitative spatial representation that computes, in a reasonable time, a set of adaptation solutions close to the initial document satisfying a profile. The quality of an adaptation can be regarded in two respects:
more » ... essiveness of adaptation solutions and computation speed. In this context, we propose a new spatial representation sufficiently expressive to adapt multimedia documents faster.

Semantic adaptation of multimedia documents

Sébastien Laborie, Jérôme Euzenat, Nabil Layaïda
2010 Multimedia tools and applications  
Multimedia documents have to be played on multiple device types. Hence, usage and platform diversity requires document adaptation according to execution contexts, not generally predictable at design time. In an earlier work, a semantic framework for multimedia document adaptation was proposed. In this framework, a multimedia document is interpreted as a set of potential executions corresponding to the author specification. To each target device corresponds a set of possible executions complying
more » ... with the device constraints. In this context, adapting requires to select an execution that satisfies the target device constraints and which is as close as possible from the initial composition. This theoretical adaptation framework does not specifically consider the main multimedia document dimensions, i.e., temporal, spatial and hypermedia. In this paper, we propose a concrete application of this framework on standard multimedia documents. For that purpose, we first define an abstract structure that captures the spatiotemporal and hypermedia dimensions of multimedia documents, and we develop an adaptation algorithm which transforms in a minimal way such a structure according to device constraints. Then, we show how this can be used for adapting concrete multimedia documents in SMIL through converting the documents in the abstract structure, using the adaptation algorithm, and converting it back in SMIL. This can be used for other document formats without modifying the adaptation algorithm.

On-the-fly Multimedia Document Adaptation Architecture

Quang Pham Hai, Sébastien Laborie, Philippe Roose
2012 Procedia Computer Science  
Currently, multimedia contents can be accessed at anytime and anywhere with a wide variety of devices, such as laptops, smartphones and tablets. In this paper, we present a service-based multimedia adaptation architecture where adaptation services can be available locally and remotely on multiple platforms. When conflicts are detected between some multimedia document properties and profile constraints, we propose a procedure that selects relevant adaptation services in order to compute an
more » ... d document. This procedure may be executed locally or remotely, moreover for unsovled conflicts this one indicates which services may have to be installed.

An Incremental Framework for Adapting the Hypermedia Structure of Multimedia Documents [chapter]

Sébastien Laborie, Jérôme Euzenat
2008 Studies in Computational Intelligence  
The multiplication of presentation contexts (such as mobile phones, PDAs) for multimedia documents requires the adaptation of document specifications. In an earlier work, a semantic approach for multimedia document adaptation was proposed. This framework deals with the semantics of the document composition by transforming the relations between multimedia objects. In this chapter, we apply the defined framework to the hypermedia dimension of documents, i.e., hypermedia links between multimedia
more » ... jects. By considering hypermedia links as particular objects of the document, we adapt the hypermedia dimension with the temporal dimension. However, due to the non-deterministic character of the hypermedia structure, the document is organized in several loosely dependent sub-specifications. To preserve the adaptation framework, we propose a first straightforward strategy that consists of adapting all sub-specifications generated by the hypermedia structure. Nevertheless, this strategy has several drawbacks, e.g., the profile is not able to change between user interactions. Hence, we propose an incremental approach which adapts document sub-specifications step by step according to these interactions. To validate this framework, we adapt real standard multimedia documents such as SMIL documents.

Hybrid molecule-based information retrieval

Nathalie Charbel, Christian Sallaberry, Sebastien Laborie, Richard Chbeir
2019 Proceedings of the 34th ACM/SIGAPP Symposium on Applied Computing - SAC '19  
The increased availability of interdependent heterogeneous data generated from different sources is fostering the incorporation of semantic knowledge-based graphs and ontologies in information management and search applications. Most of the existing Information Retrieval systems mainly focus on the semantic analysis of the information contained in heterogeneous data. In their results, they provide documents as query answers without considering (i) detailed information regarding relevant
more » ... ity levels of the documents, and most importantly (ii) dependencies between the documents or parts of the documents. To overcome these limitations, we propose a graph-based search and ranking algorithm within a generic framework that retrieves the data in the form of a novel augmented data structure for query answers, which we call hybrid molecules. The latter consist of well-defined subgraphs representing relevant contextual information regarding domainspecific information coupled with structural information related to the document. This improves the search results and reduces users' efforts in tracking and interpreting them. Experiments conducted on real world data corpus using projects from the building construction industry validate the effectiveness of our approach.

Bi-Intervals for Backtracking on Temporal Constraint Networks

Jean-Francois Baget, Sebastien Laborie
2007 14th International Symposium on Temporal Representation and Reasoning (TIME'07)  
Checking satisfiability of temporal constraint networks involves infinite variables domains. We explore a solution based upon finite partitions of infinite domains. Though a straightforward partition results in a sound and complete backtrack, its extension to forward checking is not complete. Using bi-intervals, we obtain sound and complete backtrack and forward checking algorithms. Moreover, we show that bi-intervals used in a hybrid algorithm which also instantiates constraints improve backtrack efficiency.

LinkedMDR: A Collective Knowledge Representation of a Heterogeneous Document Corpus [chapter]

Nathalie Charbel, Christian Sallaberry, Sebastien Laborie, Gilbert Tekli, Richard Chbeir
2017 Lecture Notes in Computer Science  
The ever increasing need for extracting knowledge from heterogeneous data has become a major concern. This is particularly observed in many application domains where several actors, with different expertise, exchange a great amount of information at any stage of a large-scale project. In this paper, we propose LinkedMDR: a novel ontology for Linked Multimedia Document Representation that describes the knowledge of a heterogeneous document corpus in a semantic data network. LinkedMDR combines
more » ... sting standards and introduces new components that handle the connections between these standards and augment their capabilities. It is generic and offers a pluggable layer that makes it adaptable to different domain-specific knowledge. Experiments conducted on construction projects show that LinkedMDR is applicable in real-world scenarios.

Semantic Multimedia Document Adaptation with Functional Annotations

Sébastien Laborie, Jérôme Euzenat, Nabil Layaïda
2009 2009 Fourth International Workshop on Semantic Media Adaptation and Personalization  
The diversity of presentation contexts for multimedia documents requires the adaptation of document specifications. In an earlier work, we have proposed a semantic adaptation framework for multimedia documents. This framework captures the semantics of the document composition and transforms the relations between multimedia objects according to adaptation constraints. In this paper, we show that relying on document composition alone for adaptation restricts the set of relevant candidate
more » ... and may even divert the adaptation from the authors intent. Hence, we propose to introduce functional annotations to guide the adaptation process. Theses annotations allow to refine the role of multimedia objects in the document. We show that SMIL documents could embed functional annotations encoded in RDF. These multimedia documents are then adapted thanks to an interactive adaptation tool.

Towards an interoperable device profile containing rich user constraints

Cédric Dromzée, Sébastien Laborie, Philippe Roose
2012 Proceedings of the 21st international conference companion on World Wide Web - WWW '12 Companion  
Currently, multimedia documents can be accessed at anytime and anywhere with a wide variety of mobile devices, e.g., laptops, smartphones, tablets. Obviously, platforms heterogeneity, user's preferences and context variations require documents adaptation according to execution constraints, e.g., audio contents may not be played while a user is participating at a meeting. Current context modeling languages do not handle such a real life user constraints. They generally list multiple information
more » ... alues that are interpreted by adaptation processes in order to deduce implicitly such highlevel constraints. This paper overcomes this limitation by proposing a novel context modeling approach based on services where context information are linked according to explicit highlevel constraints. In order to validate our proposal, we have used Semantic Web technologies by specifying RDF profiles and experiment their usage on several platforms.

A framework with tools for designing web-based geographic applications

The Nhan Luong, Sébastien Laborie, Thierry Nodenot
2011 Proceedings of the 11th ACM symposium on Document engineering - DocEng '11  
Many Web-based geographic applications have been developed in various domains, such as tourism, education, surveillance and military. However, developing such applications is a cumbersome task because it requires several types of components (e.g., maps, contents, indexing services, databases) that have to be assembled together. Hence, developers have to deal with different technologies and application behavior models. In order to create Web-based geographic applications and overcome these
more » ... problems, we propose a framework composed of three complementary tasks: identifying some desired data, building the graphical layout organization and defining potential user interactions. According to this framework, we have specified a unified model and we have encoded it using Semantic Web technologies, such as RDF. Through a prototype named WINDMash, we have implemented some tools that instantiate our model and automatically generate concrete Internet geographic applications that can be executed on Web browsers.
