How do Computed Ontology Mappings Evolve? - A Case Study for Life Science Ontologies

Anika Groß, Michael Hartung, Andreas Thor, Erhard Rahm
2012 International Semantic Web Conference  
Our results can be valuable for users working with ontology mappings, e.g., one can learn from past ontology/mapping changes and their correlation to estimate possible mapping changes if new ontology versions  ...  Mappings between related ontologies are increasingly used to support data integration and analysis tasks. Changes in the ontologies also require the adaptation of ontology mappings.  ...  In contrast to previous work this study focuses on the impact of ontology on mapping changes, i.e., we investigate (1) how ontology mappings change and (2) study how ontology changes correlate with mapping  ...

Fusion Approaches for Mappings between Heterogeneous Ontologies [chapter]

Thomas Mandl, Christa Womser-Hacker
2001 Lecture Notes in Computer Science  
Automatic methods for mappings between different ontologies are necessary to ensure successful retrieval of information stored in virtual digital libraries.  ...  Ordering principles of digital libraries expressed in ontologies may be highly heterogeneous even within a domain and especially over different cultures.  ...  For example, an optimal learning scheme can be identified for a mapping from a group of terms to a another group of terms in the target ontology.  ...
