Enriching instances into an ontology is an important task because the process extends knowledge in ontology to cover more extensively the domain of interest, so that greater benefits can be obtained.There are many techniques to classify instances of concepts, however, two popular ones are the statistic and data mining methods.This paper compares the use of these two methods to classify instances to enrich ontology having greater domain knowledge.This paper selects conditional random field for the statistics method and feature-weight k-nearest neighbor classification for the data mining method.The experiments were conducted on the tourism ontology.The results showed that conditional random fields methods provided greater precision and recall value than the other, specifically, F1-measure is 74.09% for conditional random fields and 60.04% for feature-weight k-nearest neighbor classification.
