.... Some high level government institutions recommend the use of mechanisms that enhance the possibility of data sharing (Arctur et al. 1998) For interoperability to take place, an agreement on the terminology in the shared area must occur through the definition of an ontology for each domain (Wiederhold 1994). Ontologies are crucial for knowledge interoperation and they can serve as the embodiment of a consensus reached by a professional community (Farquhar et al. 1996) Sharing the same ontology is a pre condition to data sharing and data integration. Kashyap and Sheth (1996) consider that there ....

....Semantic translators, also called mediators (Wiederhold 1991) use a common ontology library as a measure of semantic similarity. Dynamic approaches for information sharing, as provided by semantic translators, are more powerful than the current approaches that promote standards (Bishr 1997) Wiederhold (1994) also proposes mediation as the principal means to resolve semantic heterogeneity through an incremental domain approach that brings domains together when needed. Mediators look for geographic data and translate data into a format understandable by the end user. The mediators are pieces of ....

One possibility is to define the intersection and mutual exclusion points between the various ontologies [Wie94] 13 A classification using a generalization hierarchy A classification using an aggregation hierarchy Urban Residential Forest Land Water Commercial Industrial Evergreen Lakes Reservoirs Streams and Canals Population Area Classification (US Census Bureau) State County Rural Area ....

A critical issue in combining the various ontologies is determining the overlap between them. One possibility [Wie94] is two define the intersection and mutual exclusion points between the various ontologies. Attempts have been made to use terminological relationships between terms across different ontologies to represent the intersection points. In the OBSERVER system, synonyms have been used to represent ....

A critical issue in combining the various ontologies is determining the overlap between them. One possibility [Wie94] is two define the intersection and mutual exclusion points between the various ontologies. Another approach has been adopted in [MS95] The types determined to be similar by a sharing advisor are classified into a collection called concept. A concept hierarchy is thus generated modeling ....

....classify the metadata is the extent to which they are successful in capturing the data and information content of the documents represented in various media types. The level of abstraction at which the content of the documents is captured is very important. As suggested by others (e.g. Wiederhold [Wie94] and Gruber [Gru93] we believe that to capture the content at a level of abstraction closer to that of human beings, it is important for the metadata to model application domain specific information. It is in this context that the terms vocabulary used to design the metadata assumes special ....
