  Knowledge structures called Concept Clustering Knowledge Graphs (CCKGs) are
introduced along with a process for their construction from a machine readable
dictionary. CCKGs contain multiple concepts interrelated through multiple
semantic relations together forming a semantic cluster represented by a
conceptual graph. The knowledge acquisition is performed on a children's first
dictionary. A collection of conceptual clusters together can form the basis of
a lexical knowledge base, where each CCKG contains a limited number of highly
connected words giving useful information about a particular domain or
situation.
