An ontology-based and distributed KDD model for biomedical sources.

ABSTRACT

Knowledge discovery approaches in modern biomedical research usually require to access heterogeneous and remote data sources in a distributed environment. Traditional KDD models assumed a central repository, lacking mechanisms to access decentralized databases. In such distributed environment, ontologies can be used in all the KDD phases. We present here a new model of ontology-based KDD approach to improve data preprocessing from heterogeneous sources.
