检索性能

• Fast and high - quality document clustering algorithms play an important role towards this goal as they have been shown to provide both an navigation / browsing mechanism by organizing large amounts of information into a small number of meaningful clusters as well as to greatly improve the retrieval performance either via cluster - driven dimensionality reduction or term - weighting
  快速和高质量的文本聚类技术在实现这个目标过程中扮演了重要的角色。通过将大量信息组织成少数有意义的簇，这种技术能够提供导航浏览机制，或者，通过聚类驱动的降维或权值调整来极大地改善检索性能。
