Semantic repository and ontology mapping

This document discusses the core Semantic Technologies in DynaLearn: i) The semantic repository, which supports the online storage and access of qualitative reasoning models, ii) the grounding process, which establishes semantic equivalences between the concepts in the models and the concepts in a background knowledge source, and iii) the use of ontology matching techniques for discovering similarities between the grounded models, in order to support knowledge-based feedback during the modelling process.
The work described in this document constitutes the core of WP4. This follows the previous work done in WP2 (technical design and architecture) and it is in close relation with WP3 (workbench for conceptual modelling), which handles the interaction with the final user.
