Ontology alignment and applications
The use of ontologies is a key technology for the Semantic Web and in particular in the biomedical field many ontologies have already been developed. Many of these ontologies, however, contain overlapping information and to make full use of the advantages of ontologies it is important to know the inter-ontology relationships, i.e. we need to align the ontologies. Knowledge of these alignments would lead to improvements in search, integration and analysis of biomedical data. In this talk we give an overview of techniques for ontology alignment with a focus on approaches that compute similarity values between terms in the different ontologies. Further, we discuss the results of evaluations of these techniques using biomedical ontologies. We also give examples of the use of ontology alignment in applications such as literature search.
