| Description |
The Lexical Evaluation Function is a user defined measure to evaluate
the quality of a cluster in the process of conceptual clustering.
A simple example for a finite domain X is this one:
Let covE(C) denote the number of examples of a given
example set E, covered by the cluster C.
Let covX(C) denote the number of instances of the
example language covered by C.
Then define LEF as
LEF := 1 - covE(C) / covX(C)
