Building an ontology by transforming complex triples

Abstract

An approach for building an ontology is provided. Syntactically transformed complex triples whose core terms are identified are semantically transformed into simplified triples referring to new conceptualized core terms formed by user selections from a lexical database or by adding a suffix to core terms. The core terms are assigned to respective definitions and keys in a reference ontology, thereby retaining the semantics of the complex triples. Based on the reference ontology, an enrichment transformation of the simplified triples is performed to create simplified and enriched triples by adding relations derived from a correspondence each term in the simplified triples has with the reference ontology and by adding representations of semantics of reference ontology definitions of the terms. The simplified and enriched triples are stored as an ontology representing knowledge in an application providing the free-form text from which the complex triples were extracted.
