摘要翻译:
随机索引K树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树由于其复杂度低,在大输入下具有良好的伸缩性。它还展示了对管理不断变化的集合有用的特性。此外,它解决了以前使用K树时文档向量稀疏的问题。对算法和数据结构进行了定义、解释和激励。为了与RI一起使用,对K树进行了特定的修改。为了测量质量,进行了实验。结果表明,RI K树算法比原有的K树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.
