Ontologies are one of the best structures that serve as knowledge bases and enable the reasoning of knowledge dynamically. Hand-crafted ontologies are in excellent quality but due to its expensive nature of creation, automatic ontology construction by extracting ontological knowledge from unstructured text has now become a recent and a popular trend. This article proposed a method to auto generate new ontological knowledge from limited number of existing triples ( Triple is the simple semantic structure of Subject + Predicate + Object). It introduced two new concepts named Directed Collocation (DC) and Joined Directed Collocation (JDC), based on the existing concept called Syntactic Collocation. These concepts help in inferring new ontological knowledge-automatically. This method can be used in creating new ontologies or in extending existing ontologies for either domain specific or open domain context.
