Abstract
A process of identifying terms or sets of terms in target domains having functional relationships (roles) analogous to terms (contained in the query) selected from a source domain whereby queryrelevant but semantically distant (novel) analogies may be retrieved, corresponding to any user defined query. The process is capable of discovering deep functional analogies between terms in source and target domains, even where there is a misleading superficial matching of terms (i.e. same terms, with different meanings) between the query and the target domains. The process comprises the automated generation of abstract representations of source domain content, and application of the abstract representations of content to the efficient discovery of analogous objects in one or more semantically distant target domains. Said abstract representations of terms are preferably vectors in a high dimensionality space, encapsulating characteristic occurrence patterns of terms in the source domain.
