In this paper, we propose an educational system for children with special needs. The system is based on multimedia technology to teach the children in an interactive and innovative way. It uses formal concepts analysis and a simple ontology to extract the keywords from texts related to the animals and foods domains. We link these keywords with multimedia elements which are fetched from Google database using Google APIs. These keywords represent the main entities of the texts that include the named entities, the main characters, period and actions. We discuss also the FCA extraction algorithms and we propose some improvement. The system is divided into different modules with a simple interface allowing the instructors to input the text and get the corresponding multimedia elements. They can browse easily through these elements and select what is suitable for the children.
