A method to update an ontology: simulation

摘要

In this paper, we present a method to add a new concept in a specific ontology (called basic ontology O_b). This method uses a reference ontology (called general ontology O_g) to add a new concept in a basic ontology. The reference ontology has the new concept and all the concepts of the basic ontology. The proposed method has three steps. Firstly, we use a semantic similarity measure in the reference ontology to find the most similar concept to the concept to add in the basic ontology. Secondly, we look for the right position of the concept to add relative to the most similar concept in the basic ontology. Finally, we insert the concept in the basic ontology by respecting its hierarchical structure. To illustrate our method, we use the whole WordNet1 as the reference ontology and a branch of WordNet as basic ontology.
