Improving the Search for Learning Objects with Keywords and Ontologies

We report on an ongoing project which aims at improving the e ectiveness of retrieval and accessibility of learning object within learning management systems and learning object repositories. The project Language Technology for eLearning approaches this task by providing Language Technology based functionalities and by integrating semantic knowledge through domain-speci c ontologies. We will report about the development of a keyword extractor and a domain-speci c ontology, the integration of these modules into the learning management system ILIAS and the validation of these tools which assesses their added value in the scenario of searching learning objects across di erent languages.
