摘要：
An information retrieval (IR) system with query expansion on a low-cost high-performance PC cluster environment is implemented. We study how query performance is affected by query expansion and two declustering methods using two standard Korean test collections. According to the experiments. the greedy method shows about 20% enhancement overall when compared with the lexical method.
