论文摘要
我们研究了知识如何在给定的知识空间中渗透和群集。我们介绍了一个简单的知识组织模型，每个贡献都涵盖了一定数量的项目。如果此贡献与某些阈值以上的其他人重叠，则它们会形成一个集群。贡献也可以将群集合并在一起。我们研究了全球知识和集群动力学的增长，均显示出非平凡的行为。
We investigate how knowledge percolates and clusters in a given knowledge space. We introduce a simple model of knowledge organization in which each contribution spans a certain number of items. If this contribution overlaps with others above a certain threshold, they form a cluster. A contribution can also merge clusters together. We study the growth of global knowledge and the cluster dynamics, both showing a nontrivial behavior.
