How do I choose appropriate strictness values when entering a topic phrase?
To determine the optimal strictness for a phrase, start with a default setting, then evaluate the captured events and adjust the strictness accordingly. Experimentation is key to finding the right balance between precision and recall.
Longer phrases with more meaningful words often require less strict matching. For example, a three-word phrase might match effectively with medium strictness (two out of three words), while a five-word phrase might only need three matches (medium-low strictness). The ideal strictness depends on the specific phrase and its intended use.
Below are some examples where adjusting strictness can either help or hinder your results, highlighting the importance of tweaking strictness for the best precision/recall tradeoff.
