1. A method for performing synthesis of relationships between a plurality of concept definitions using a domain of information, wherein the domain of information is a faceted domain that comprises a plurality of facets each having a plurality of facet attributes, wherein each of the concept definitions comprises at least one of the plurality of facet attributes, and wherein the method comprises: determining whether any explicit relationships exist between the plurality of concept definitions, wherein an explicit relationship is determined to exist between any two of the plurality concept definitions if the two of the plurality of concept definitions share at least one common facet attribute or each has a facet attribute of the same lineage in at least one facet attribute hierarchy of the plurality of facet attributes; determining whether any implicit relationships exist between the plurality of concept definitions, wherein an implicit relationship between two of the plurality of concept definitions is determined to exist based on a statistical identification of a relationship between a facet attribute in a first of the two of the plurality of concept definitions and a facet attribute in a second of the two of the plurality of concept definitions; and when it is determined that at least one explicit relationship and/or at least one implicit relationship exists between two of the plurality of concept definitions, synthesizing a relationship between the two of the plurality of concept definitions.
