System and method for generating new concepts based on existing ontologies

A method for creating new concepts in existing ontologies based on new concept descriptions expressed in a natural language format, comprising the steps of:

• identifying whether the received new concept description has a normalized format, and if the received new concept description does not have a normalized format, transforming the new concept description of the un-normalized format into a normalized description, wherein said normalized concept description includes one or more description part(s) having kernel concepts, said description parts can only contain the terms which can be identified in said existing ontology, and each said kernel concept contains a headword and zero or more property(s);
• and
• identifying the kernel concepts in each normalized concept description part, and extracting the identified kernel concepts, related properties, and the relations among the kernel concepts, thereby generating an expression of the new concept based on existing ontologies.
