Integrating Ontologies Using Ontology Learning Approach

Lihua ZHAO, Ryutaro ICHISE
2013 IEICE transactions on information and systems  
In this paper, we propose a Mid-Ontology learning approach that can automatically construct a simple ontology, linking related ontology predicates (class or property) in different data sets.  ...  However, manually checking each data set is time-consuming, especially when many data sets from various domains are used.  ...  To adapt to the LOD data sets, we designed an automatic ontology learning approach, which can construct an integrated ontology from various linked data sets.  ...
