If you can't articulate the link in a complete sentence, delete it — vague links are noise
When building connections between notes, test each link by asking whether you can articulate the relationship in a complete sentence—if you cannot, delete the link rather than inflating density metrics artificially.
Why This Is a Rule
Link density is not a quality metric — link quality is. A knowledge graph with 1,000 vague links ("these are kind of related") performs worse than one with 200 articulated links ("A contradicts B because X") because the vague links pollute retrieval results and graph traversal without adding semantic value.
The complete-sentence test is the quality gate: for every link, can you write a sentence describing the relationship? "Note A [specific relationship verb] Note B because [specific reason]." If you can → the link encodes genuine knowledge. If you can't → the link encodes a vague association that will produce noise during retrieval and traversal.
Vague links feel productive ("I'm building my graph!") while degrading the graph's signal-to-noise ratio. Each vague link adds one more irrelevant result to every search that touches either note. Over time, the noise from thousands of vague links makes the graph less useful than a flat search of unlinked notes.
When This Fires
- During any linking session in your knowledge system
- When reviewing existing links for quality
- After creating a batch of links and wanting to verify quality
- When graph search results feel noisy — too many vaguely related results
Common Failure Mode
Creating links because notes share vocabulary: both mention "feedback," so they must be related. But one note is about performance feedback and the other about feedback loops in systems. The vocabulary overlap created a link that encodes zero relational knowledge — and will produce false matches during search.
The Protocol
For every link you create: (1) Attempt to articulate: "Note A [verb] Note B because [reason]." (2) If you can write a complete, specific sentence → keep the link. Add the sentence as the link's label or annotation. (3) If you can't → the relationship is vague. Delete the link. (4) During periodic link audits: review existing links with the same test. Links you can't articulate have degraded in value since creation — the relationship you vaguely sensed has been forgotten, which means the link now serves no purpose.
