abstract = "An algorithm is presented for learning concept
classification rules. It is a hybrid between
evolutionary computing and inductive logic programming
(ILP). Given input of positive and negative examples,
the algorithm constructs a logic program to classify
these examples. The algorithm has several attractive
features, including the ability to use explicit
background (user-supplied) knowledge and to produce
comprehensible output. We present results of using the
algorithm to a natural language processing problem,
part-of-speech tagging. The results indicate that using
an evolutionary algorithm to direct a population of ILP
learners can increase accuracy. This result is further
improved when crossover is used to exchange rules at
intermediate stages in learning. The improvement over
Progol, a greedy ILP algorithm, is statistically
significant (P<0.005)",
