METHOD AND APPARATUS FOR PROCESSING ELECTRONIC DATA

摘要

A system (100) for generating a computer readable data file representative of a mapping between a first representation of a set of concepts or of a data structure (e.g. a database schema) and a second representation of a set of concepts or of a data structure (e.g. an ontology), each representation comprising a plurality of complex representational elements (e.g. tables in a database schema and concepts in an ontology) each of which may itself include a number of associated subordinate representational elements (e.g. columns/fields of a table in a database schema and attributes of a concept in an ontology). The system (100) includes a semantic similarity calculation module (134) for calculating a semantic similarity measure between a subordinate element of the first representation and each of the subordinate elements in the second representation and a mapping generation module (137) for generating a mapping between the subordinate element of the first representation and one of the subordinate elements of the second representation selected in dependence upon the calculated semantic similarity measures between the subordinate elements.
