What is semantic links?

A link labeled causes is more useful than a generic link labeled related.

Example: You have two notes: 'Sleep deprivation' and 'Decision fatigue.' A generic link says they're related. A typed link labeled 'causes' says sleep deprivation produces decision fatigue. Another typed link labeled 'exemplifies' from a note on 'Your Monday afternoon meeting disasters' to 'Decision fatigue' explains why. Now you can traverse a causal chain — not just see a cloud of associated topics.

This concept is part of Knowledge Graphs in the How to Think curriculum, which builds the epistemic infrastructure for knowledge graphs.
