我从两组不同的报纸文章中获得了两组主题。

换句话说，Cluster_1 =${x_1, x_2, ..., x_n}$包括'X'报纸集的主要主题和Cluster_2 =${y_1, y_2, ..., y_n}$包括“Y”新闻纸集的主要主题。

现在，我想通过考虑下面示例中给出的集群属性来查找两组相似/相关的集群。

Example 1,
**X1 in Cluster_1** is mostly similar/related to **Y2 in Cluster_2**
**X2 in Cluster_1** is mostly similar/related to **Yn in cluster_2**
and so on.

Example 2:
News about Yet in Cluster_1 is mostly similar/related to News about Science in Cluster_2
News about Floods in Cluster_1 is mostly similar/related to News about Rains in Cluster_2

因为，我正在处理两组单独的集群，我可以使用什么合适的测量/方法来连接两组不同的集群？
