Semantic annotator

The goal of the Semantic Annotator is the (semi-)automatic semantic annotation of learning resources by analysing their description (and content) with the help of (multilingually annotated) topic / skill ontologies.

This facilitates improved retrieval of learning resources:
- In addition to normal full-text search, users can navigate through an ontology to specify (or refine) their queries.
- Full-text queries can be evaluated in a more advanced way by first mapping the user input to ontological concepts which are then used for the retrieval; this allows multi-lingual access since the concepts are themselves language-independent.

Since the annotations are based on an ontology, they can be used for inferencing (e.g. for personalisation), query expansion, and ranking search results (by taking the structure of the ontology into account, e.g., using path lengths to assess concept similarity).
