UC San Diego researchers have
developed a novel technique to perform
information mediation across
heterogeneous sources, even when the sources
to integrate. This is accomplished by a novel
architecture that allows information sources
to be converted
into "knowledge sources." Such a knowledge
source not only exports its logical structure
capabilities to the mediator, but exports its
domain constraints, and any relationships not
obvious from the data.
The mediator also allows a domain expert to provide additional domain knowledge in a declarative manner—this domain knowledge serves as the "glue" that the mediator uses to logically compute how two seemingly unconnected information sources are related. The "glue knowledge" is represented as a graph called the domain map. When a mediator answers a query against an integrated view, it places the results in the context of the domain map—thus the partial results searched out from different data sources are all represented in the domain map and connected through a commonly accepted domain knowledge framework. This architecture has been successfully applied to different application areas, including neuroscience.
