一种基于内准则函数的文本聚类分析方法

An Analytical Approach to Document Clustering Based on Internal Criterion Function

Alok Ranjan, Harish Verma, Eatesh Kandpal, Joydip Dhar

摘要:

快速、高质量的文档聚类是组织信息、从用户查询中获取搜索引擎结果、增强Web爬行和信息检索的重要任务。随着大量的数据可用,并与创建高质量的集群的目标,各种算法已经开发出具有质量复杂性权衡。在这些算法中,一些算法试图使用为整个聚类解集定义的某些准则函数来最小化计算复杂性。在本文中,我们提出了一种新的文档聚类算法的基础上的内部准则函数。大多数常用的分区聚类算法(例如k-means)都有一些缺点,因为它们存在局部最优解和创建空簇作为聚类解决方案的问题。该算法通常不会受到这些问题的影响,并收敛到全局最优值,其性能随着簇数的增加而增强。我们已经针对四个不同的k值(所需的聚类数)的三个不同的数据集检查了我们的算法。

英文摘要:

Fast and high quality document clustering is an important task in organizing information, search engine results obtaining from user query, enhancing web crawling and information retrieval. With the large amount of data available and with a goal of creating good quality clusters, a variety of algorithms have been developed having quality-complexity trade-offs. Among these, some algorithms seek to minimize the computational complexity using certain criterion functions which are defined for the whole set of clustering solution. In this paper, we are proposing a novel document clustering algorithm based on an internal criterion function. Most commonly used partitioning clustering algorithms (e.g. k-means) have some drawbacks as they suffer from local optimum solutions and creation of empty clusters as a clustering solution. The proposed algorithm usually does not suffer from these problems and converge to a global optimum, its performance enhances with the increase in number of clusters. We have checked our algorithm against three different datasets for four different values of k (required number of clusters).
