Learning ecosystem is a coherent set of training biocenes that promotes collaborative learning and allows exchanging and sharing of knowledge and/or skills for succeeding in a common project. Learning ecosystems have changed the learning mode. Nowadays, the customers (the learners in our case) teach us what they want, hence, training can become the pilot of this change. The collaborative environment E-Memorae2.0 is organized into a set of learning ecosystems that share a set of learning resources. In this paper, we propose a semantic recommendation approach of the pedagogical resources within learning ecosystem. This approach is based on a voting system that enables each member of the ecosystem to assess the appropriateness of one or more pedagogical resources found in his/her sharing space about a specific subject.
