Linguistically Light Lexical Extensions for Ontologies

An increasing number of enterprises are beginning to include semantic web ontologies into their Information Extraction (IE) and Text Analytics (TA) applications. This can be challenging for a TA group wishing to avail of semantic web ontologies due to the manual effort of retargeting and tailoring language resources within the TA system to a new domain to meet customer needs.
