Recuperación inteligente de contenidos digitales educativos
[EN] The last decade has seen a significant evolution in the methods for managing and organizing large volumes of digital content. The use of the Internet as a vehicle and container for such a large volume of data warehouses has led to a phenomenon of globalization and decentralization. The information is characterized in various ways, and contained in specialized data repositories each of which must be accessed by their own methods, resulting in dozens of communication protocols. Therefore, there is a need for research on the techniques, tools and methodologies that provide a technological solution that enables the adaptation of mechanisms in an environment that is (i) the sum of open contexts (ii) highly dynamic, and (iii) heterogeneous. The education sector is a significant generator, consumer and depository for educational content. These aspects position the current educational environment in a relevant sector in the development and integration of emerging solutions to management processes for the location and distribution of digital content. Users have access to technologies that allow them to obtain information ubiquitously and in real-time. This openness in communication and the urgent need to achieve true interoperability between educational application environments have created the need for research in the search, retrieval and integration of heterogeneous educational content. The problems arising from the integration of educational content are usually caused by the multiple characterizations of the content, the vast amount of educational content distributed, and the access to them required by different users In addition, new Web applications handle information distributed in different geographical areas making the integration of data and application security even more complicated and in many cases, impossible to fully guarantee. Finally, there is the additional problem of the communication channels through which information travels, such as Internet. Multi-agent systems are known for their ability to adapt quickly and effectively to changes in their environment. This work proposes a model for the development of digital content retrieval based on the paradigm of virtual organizations of agents. The model allows the development of an open and flexible architecture that supports the services necessary to conduct a search for distributed digital content dynamically. The AIREH (Architecture for Intelligent Recovery of Educational content in Heterogeneous Environments) is based on the proposed model; it is a multi-agent architecture that can search and integrate heterogeneous educational content through a recovery model that uses a federated search. This study demonstrate the possibility of modeling an efficient system for managing open systems from a model of an adaptive organization that provides distributed planning, and is flexible and dynamic. The model and the technologies presented in this research are an example of the potential for developing recovery systems for digital content based on the paradigm of virtual organizations of agents. The advantages of the proposed architecture are its flexibility, customization, integrative solution and efficiency.
