In this paper, we study how to better merge a WordNet-like ontology with an online encyclopedia. We first eliminate the noises with some heuristic rules, and then adopt a domain-dependent strategy to trim the encyclopedia structure. Finally, we integrate entities from the trimmed structure into the original ontology, and construct a refinedly-enriched ontology. The experimental results show that this ontology can achieve better performance than the original version as well as a coarsely-enriched version constructed without pruning and trimming.
