Re-using pre-existing electronic information has become a new perspective able to reduce the development costs of intelligent learning environments (ILE). This approach has to face the problem of organizing and structuring this pre-existing information in a way that ease users’ understanding and assimilation. The automation of the Formal Concept Analysis (FCA) theory is proposed as a way to structure conceptually the reused information and as a suitable method to implement different interaction techniques. Therefore, the FCA can be a relevant and competitive method for the production of ILEs, and specifically in the construction of intelligent assistants.
