Abstract:
1. A method for creating a relativistic metric for measuring distances between sub-structures in an ontology implemented using a computer having a microprocessor, comprising: setting, using the microprocessor, a fixed distance, between a top of a first order structure and each sub-structure in the order structure, to a constant value independent of the depth of the order structure, thereby generating relativity between sub-structures, the sub-structures corresponding to concepts, relationships or attributes of an entity; creating, using the microprocessor, a model of the ontology based on a hierarchy of the sub-structures in the order structure using the fixed distance and a plurality of factors forming the basis of a relativistic conceptual distance metric; obtaining a data set; generating, using the microprocessor, a second order structure for the data set; generating, using the microprocessor, a semantic distance field for clustering by applying the second order structure and the data set to the model of the ontology created in the creating step, the creating step further creating the model of the ontology by mapping concepts and features to create a vector-valued partial order structure based on the plurality of factors forming the basis of the relativistic conceptual distance metric, computing relative conceptual distances using the vector-valued partial order structure, and defining a Semantic Distance Field model based on the relative conceptual distances; performing data clustering based on the generated semantic distance field in an N dimensional space; and inducing, using the microprocessor, the ontology from the data clustering performed by the performing step.
