Abstrakt

The "Language Technology for eLearning" (LT4EL) project integrates semantic knowledge in a Learning Management System to enhance the management, distribution and especially the cross-lingual retrieval of learning material. One of the results achieved in the project is the construction of a language-independent domain-ontology with lexicons of eight languages linked to it. Learning objects of these languages have been annotated with concepts from this ontology. The ontology management system allows for semantic search which has been proven to be more effective than simple full text search for all languages of the project.
