Abstract

This article addresses the interoperability between the semantic learning platforms and the educational resources banks, more precisely between the LOM and MPEG-7 standards. LOM is a set of metadata associated with e-learning content, while MPEG-7 is a standard for describing multimedia content. The use of educational resources has become an essential component to meet the learning needs. Given the multimedia nature of these resources, such use causes problems in the interoperability of multimedia learning objects in e-Learning environments, indexing and retrieval of digital resources. Faced with these problems, we propose a new approach for the multimedia learning objects by using the ontology mapping between the LOM and MPEG-7 ontologies.

Highlights

With the observed increase in the use of multimedia content in the e-Learning environments, the specialists in the field of engineering Educational Multimedia, consider the support of multimedia by the e-learning systems as an essential criterion for enhance the learning process, making it more natural and spontaneous operation
The mass and nature of digital resources involve the use of a standard to facilitate the search and indexing of these resources, the standard MPEG-7 is, in our approach, a framework to create the metadata of multimedia learning objects .But the nature of the multimedia content does not favor the semantics, which reflects negatively at the main characteristics of learning objects such as reuse, flexibility, adaptability and interoperability

Summary

Introduction

With the observed increase in the use of multimedia content in the e-Learning environments, the specialists in the field of engineering Educational Multimedia, consider the support of multimedia by the e-learning systems as an essential criterion for enhance the learning process, making it more natural and spontaneous operation. We value the non-linear thinking by giving more freedom to the learner to determine its own way of learning. The need for digital resources is a intournable action in so far as it gives more freedom to learners to personalize their learning path, to achieve this goal, several organizations have set up a banks of digital resources. The mass and nature of digital resources involve the use of a standard to facilitate the search and indexing of these resources, the standard MPEG-7 is, in our approach, a framework to create the metadata of multimedia learning objects .But the nature of the multimedia content does not favor the semantics, which reflects negatively at the main characteristics of learning objects such as reuse, flexibility, adaptability and interoperability. We discuss in this article, the multimedia content description, the solution mapping ontologies based on the correspondence between the two ontologies source.
