Interdisciplinarity will become, not only a way of content restructuring, but also a new way to organize learning. This paper proposes a framework for building ontology for e-learning and aims for a navigation and efficient retrieval and reuse content in the “virtual university”. The framework used the content annotation Learning Object (LO), and t...

... which can be used or reused in e- learning technology. Also, a learning object may be considered a collection of elements of independent media (interactivity, architecture, context) and metadata. These metadata can be enriched with concepts specific ontology of the domains, so that each LO is assigned a structure description based on ontology (Fig. 5). More than one learning objects, are assembled by authors to form the rates, and then they are released for consumption. Being created, the ontology for learning object (LO) can be integrated so as to allow efficient retrieval of the content and the ability to be re-attached (Fig. 6). SCORM reflects the tendency of unification of the ...

Since 1972 and the launch of Landsat 1-the first Earth Observation civilian satellite-millions of images have been acquired all over the Earth by a constantly growing fleet of more and more sophisticated satellites. Generally, searching within this huge amount of Earth Observation (EO) images is limited by the description of the acquisition conditi...
Searches on the Web of Data go beyond the retrieval of textual Web sites, and shifts the focus of search engines towards domain-specific entity data, for which the units of retrieval are domain-specific entities instead of textual documents. We study the effect of using semantic annotation in combination with a knowledge graph for domain-specific e...
Resumen El uso de tecnologías de la Web Semántica ha venido acrecentándose, por lo que es común usarlo en diferentes aspectos. Este trabajo evalúa como estas tecnologías pueden contribuir a mejorar la indexación de artículos en revistas científicas. Inicialmente, se hace una revisión conceptual de los metadatos, para posteriormente estudiar las tec...
Linked Data seem to play a seminal role in the establishment of the Semantic Web as the next-generation Web. This is even more important for digital object collections and educational institutions that aim not only at promoting and disseminating their content but also at aiding its discoverability and contextualization. In this paper we show how re...
Entity linking is the task of mapping potentially ambiguous terms in text to their constituent entities in a knowledge base like Wikipedia. This is useful for organizing content, extracting structured data from textual documents, and in machine learning relevance applications like semantic search, knowledge graph construction, and question answerin...

... It is important to classify the media content using ontologies in order to increase the semantic description of the content but also to decrease the metadata, which sometimes, are too expensive to be created. Such an ontology, to annotate the LO (Learning Object) content has been proposed in our former paper [6]. This allows the analysis, the recognition of concepts and relationships between them and it is describe in Fig. 3. ...
Using the video data to realize the synchronized presentations SMIL, within the e-learning platforms
requires efficient management thereof, and the use of specific resources offered by SMIL language.
Often at presentation is the need to use or reuse the pieces or fragments of content, called LO
(Learning Object). The use of ontologies in the field of e-learning, semantic annotation allow the
analysis of the content, recognising the concepts and the relation between them, it will increase the
accuracy of search and retrieval of video content and reuse it. In this context the MPEG-7 provides the
advantage of description and retrieves video content, based on ontology. Due to the fact that SMIL
language is a XML language, presentations can easily integrate other types of XML documents, so the
MPEG-7 documents. The paper proposes a framework that uses the MPEG-7 standard, to provide the
tools for semantic annotation of video content and integrating them into the SMIL language.
In recent years the phenomenal development of content and multimedia services, as well as the technical progress of mobile devices (smartphone, tablets), have led to a new direction in the educational field, based on Cloud Computing. Services provided and applications offered through Cloud Computing at a relatively low cost, together with running them on a scalable infrastructure, will determine future migration towards this kind of platforms. The advantage offered by diversity, flexibility and virtualization of multimedia resources that can all be made available to the user in Cloud Computing, requires their effective management, for use or reuse in courses. Thus, the use of some domain-specific ontologies for e-learning, for annotation of the LO (Learning Object) content and LOM (Learning Object Metadata) structure, will result in browsing, search and optimal retrieval. This paper proposes a system’s architecture for video data modelling through annotation, semantic classification and content retrieval based on the MPEG-7 standard that makes use of the Cloud Computing benefits.
