摘要:

随机索引(RI)K-tree是两种聚类算法的结合。文档聚类中存在着许多大规模的问题。RI K树由于其低复杂度而在大输入下具有良好的扩展性。它还展示了对管理不断变化的集合有用的功能。此外,它解决了以前使用K树时文档向量稀疏的问题。算法和数据结构的定义,解释和动机。对K树进行特定修改以用于RI。已经进行了实验来测量质量。实验结果表明,RI K-tree算法比原始K-tree算法提高了文档聚类质量。

英文摘要:

Random Indexing (RI) K-tree is the combination of two algorithms for clustering. Many large scale problems exist in document clustering. RI K-tree scales well with large inputs due to its low complexity. It also exhibits features that are useful for managing a changing collection. Furthermore, it solves previous issues with sparse document vectors when using K-tree. The algorithms and data structures are defined, explained and motivated. Specific modifications to K-tree are made for use with RI. Experiments have been executed to measure quality. The results indicate that RI K-tree improves document cluster quality over the original K-tree algorithm.
