Designing and Implementing an Information Retrieval System HyperManyMedia platform: an integrated and working E-learning system for retrieving personalized semantically enriched learning resources. Within this context, this research provides architecture divided into four layers: i) Semantic Representation (knowledge representation), ii) Algorithms, which are the core engine of this study ; iii) Personalized Interface to deal with information filtering, and iv) Dual representation of the semantic user profile. It uses Cluster Analysis in support of an adaptive personalized search for E-learning. The platform provides online students with the following search capabilities: Metadata Search, Semantic Search, Visual Search, Recommendations, and Relevant User Feedback:
