Abstract:

The Internet of Things (IoT) is an emerging paradigm which suggests the expansion of Internet towards a network where computers, people and objects are interconnected, produce data and communicate among themselves. From the point of view of learning, transformations implied by IoT offer new opportunities. Indeed, the connected devices multiplication and the ubiquity of communication networks widen and vary learning spaces. Likewise, with Big Data, in other words data generated by countless sensors incorporated in day-to-day life's objects and the use of service's platforms it becomes possible to track the activities and evolution of learners. Connected devices pervasivity and Big Data help increase the amount of information available on the internet whether it is numbers, videos, tutorials, blogs, MOOCs, scientific papers or pedagogical tools. Learners and teachers are coping thousands of results in which the most relevant numeric pedagogical resources (NPR) are lost. On the other hand, resources accessibility is also limited by a silos model which the Web 2.0 is based on: a set of closed platforms which communicate little or no among themselves. With the IoT development, accessibility and interoperability became critical characteristics of NPR. In this context, the use of web semantic technologies, and more specifically Linked Data, can improve this NPR characteristics. Indeed, the main goal of these kinds of technologies is to foster data accessibility and interoperability over the Web by making those machine-readable. Linked Data implies the use of web technologies for data formal description and creation of links among themselves so that data became be part of the web just like documents. The application of Linked Data concept on online educational resources can initially contribute to make an easiest access to resources. NPR are then identifiable in a relevant way and computers become able to understand both learners queries meaning and NPR' meaning. Secondly, the interconnection among NPR reduce negative effects of the silos model. In doing so learners and teachers have available necessary tools to query and link NPR's from different sources on the Web.
