K-tree:大规模文档聚类

K-tree: Large Scale Document Clustering

Queensland University of Technology(昆士兰科技大学)

Christopher M. De Vries, Shlomo Geva

摘要:

我们在信息检索上下文中引入K树。它是k-means聚类算法的有效近似。与k均值不同,它形成了集群的层次结构。它已经扩展到解决稀疏表示的问题。我们使用文档集合将性能和质量与CLUTO进行比较。K树具有较低的时间复杂度,适用于大型文档集合。这种树结构允许在空间需求超过主存的情况下实现基于磁盘的高效实现。

英文摘要:

We introduce K-tree in an information retrieval context. It is an efficient approximation of the k-means clustering algorithm. Unlike k-means it forms a hierarchy of clusters. It has been extended to address issues with sparse representations. We compare performance and quality to CLUTO using document collections. The K-tree has a low time complexity that is suitable for large document collections. This tree structure allows for efficient disk based implementations where space requirements exceed that of main memory.
