The Coherence score of a Cluster indicates how similar the documents are to another cluster. Is this statement true or false?

The statement is false because the Coherence score of a Cluster actually measures how well the documents within that specific cluster relate to one another, rather than to another cluster. A high Coherence score indicates that the documents share a common theme or topic, showing their internal cohesion. In contrast, the similarity to other clusters is typically assessed through different metrics that evaluate the distinction or overlap between clusters. Therefore, understanding the Coherence score in terms of the internal similarity of documents within a cluster is crucial to grasping how it functions in cluster analysis.
