What does the Coherence score of a Cluster signify?

The Coherence score of a Cluster signifies conceptual similarity within the cluster. It measures how closely related the documents are to each other in terms of their underlying concepts or topics. A high Coherence score indicates that the documents within the cluster share a strong relationship in content, themes, or ideas, suggesting that they collectively represent a coherent concept.

This score is particularly useful in evaluating the quality of the clustering process, as it reflects the degree to which the documents align with each other conceptually rather than just being grouped by arbitrary characteristics. A well-defined cluster with high Coherence will enable users to draw insights and narratives effectively based on the common threads that link the documents together.
