Topic Modeling with LDA: Optimizing K via a Verified Component

The Topic Scorer (Labs) verified component implements an experimental score for semantic coherence, exclusivity and similarity/distance of topics of one or multiple models.

As K increases trends can be found using these scores and a decision for the optimal K can be used. Usually it is a tradeoff between those metrics. Read more on the Verified Components descriptions.
