Relationship Strength
Knowledge GraphsRelationship Strength is a numeric value representing how strongly two nodes connect in a knowledge graph, quantifying the semantic connection intensity between nodes — 'Inheritance Law' → SHARES_ATTRIBUTE → 'Family Law' with strength=0.9 indicates a much stronger relationship than one with strength=0.3.
In SEO, relationship strength drives internal linking strategy. Stronger relationships get priority placement higher on pages with descriptive anchor text. You can calculate strength automatically by counting shared attributes between nodes, or use LLMs for context-based analysis. Strength values are typically normalized to a 0–1 scale with cutoff thresholds such as 0.5 to ignore weak relationships when planning internal links.
This prioritization becomes clear in practice. Consider 'forced heirship' connecting to 'will' with a strength of 0.95 compared to 'forced heirship' connecting to 'income tax' at 0.3. This demonstrates clear linking prioritization. Relationship strength also enables graph filtering — showing only relationships above 0.7 creates cleaner visualizations without weak-connection noise.
