“…To overcome problems due to semantic heterogeneity, it is useful to use ontologies (Wache et al, 2001). Depending on how ontologies are used, data integration systems can adopt different approaches, such as single ontology (adopted in SIMS (Arens et al, 1993;Arens, Hsu & Knoblock, 1996)), multiple ontology (adopted in OBSERVER (Mena et al, 1996b;Mena et al, 1996a)) and hybrid (adopted in KRAFT (Preece, Hui & Gray, 1999;Preece et al, 2000) and COIN (Goh et al, 1999)).…”

“…Finally, ontologies can serve to support knowledge level interoperability among heterogeneous knowledge sources [19,20]. They provide a layer between an agent (human or artificial) and the physical knowledge sources, by formally defining the domain knowledge and explicitly specifying the content of the knowledge sources using the concepts of the ontology (meta-models).…”

“…Common ontology approach is to develop a global ontology (shared vocabulary) to identify and associate semantics in information resources explicitly or implicitly, and the user query is issued according to the global ontology. This approach was taken by many projects [12] , such as SIMS [21] , TSIMMIS [18] , Infosleuth [3] , KRAFT [1] ,PICSEL [5] , DWQ [4] , Ontobroker [19] , SHOE [8] , MECOTA [7] and BUSTER [20] . A global ontology is developed by extracting the implicit or explicit semantics from the data resources, but in general the semantics in the data sources cannot be preserved during the ontology extraction and integration process with current approaches due to the arbitrariness that seems in existence in many cases in the developing process of the global ontology.…”
