Treat individual notes, concepts, papers, or stakeholders as nodes, and represent relationships as edges that carry intent, such as supports, contradicts, elaborates, cites, depends on, or similar to. Rich, typed edges reduce ambiguity and encourage precise thinking. A fleeting note about a conference talk can become a node that later connects to a method comparison you write, forming a path others can follow. Meaning deepens as each new link clarifies how knowledge pieces reinforce or challenge one another.
Use directed edges to show directionality—causal flow, influence, or citation—where order matters. Use undirected edges for symmetric relationships like similarity or co-occurrence. Apply weights to communicate strength, confidence, or recency, letting algorithms and humans prioritize. For example, a policy researcher can assign higher weights to peer-reviewed sources and lower weights to blog references, preserving nuance without silencing weaker signals. Over time, adjusting weights reveals how evidence evolved, encouraging responsible interpretation rather than simplistic certainty.
Start with simple, flexible tagging to capture intuition quickly, and progressively evolve toward a light ontology that encodes recurring patterns. Define consistent link types, canonical names, and a small set of node classes—idea, method, evidence, stakeholder, decision—to stabilize meaning. A personal wiki might gradually standardize messy labels into predictable structures without stifling exploration. This shift keeps your network accessible to newcomers while enabling more reliable queries. Avoid over-engineering; the goal is clarity that invites contribution, not rigidity.
