Effective information retrieval is not provided with manual multimedia processing methods against huge amount of multimedia data which is produced in nowadays. Even automatic annotation generation methods are hard to address, they only operate on image processing step. Ultimately, it does not mean having a system that retrieve, relate and interpret the retrieved data. This study is done for filling...
The description of an audiovisual document represents a major challenge for multimedia retrieval. Indeed, the lack of descriptive metadata extraction makes these proliferated resources underused in the querying process. To overcome these difficulties, the extraction of the semantic metadata of the content and the different structures of an audiovisual document is required. In this paper, we present...
As practice and profession, education has always been a discipline in the heart of the development of systems and hypermedia applications. With through work which was completed, we note that the great majority of the studies was interested in the aspects of access to information and the challenges posed by exploration. Thus, most of work explored, for example, the cognitive overload or confusion during...
Recently, Web-based news publishing is evolving fast, as many other Internet services, and nowadays this service is trying to adapt information in manners that better fit user's interests and capabilities in the digital space. In this paper, we propose a semantic link network portal for multimedia content recommendation. The portal is based on Semantic Link Network technologies and attempts to build...
The World Wide Web hosts ever-increasing volumes of diverse data and associated services that cannot be fully exploited unless appropriate management and integration technologies are developed. To cover this need, the semantic Web was introduced as the second-generation WWW, enriched by machine-understandable data which supports the user in his tasks. The rapid growth of the Web has produced an explosion...
News production is characterized by complex and dynamic workflows in which it is important to produce and distribute news items as fast as possible. In this paper, we show how personalized distribution and consumption of news items can be enabled by automatically enriching news metadata with open linked datasets available on the web of data, thus providing a more pleasant experience to fastidious...
Multimedia content adaptation is gaining importance because of the growing amount of multimedia content on the one hand and the growing diversity in usage environments on the other hand. Furthermore, to deal with the growing amount of coding formats for multimedia content, format-independent adaptation systems are desired. These systems support the exploitation of scalability to meet the usage environment,...
The role of metadata is gaining importance due to today's growth of multimedia content. Currently, XML is the standard for data interchange. However, as XML Schemas do not express semantics but rather the document structure, there is a lack of semantic interoperability regarding current (XML-based) metadata standards. By using semantic Web technologies, ontologies can be created to describe the semantics...
Nowadays, the research of crawlers moves closer to the semantic web, along with the appearance of increasing XML/RDF/OWL files and the rapid development of ontology mark-up languages. As an emerging concept, metadata abstraction crawlers are a series of crawlers that aim to abstract metadata from normal HTML documents, based on various semantic Web technologies. In this paper, we make a general survey...
