Centrality Beats Mention
A single load-bearing idea anchors the entire patent.
Centrality Beats Mention — Two documents can both mention the query entity. One mentions it once in a sidebar; the other is structured around it. A pure mention-count signal cannot distinguish them. Centrality does. This patent ranks candidate...
Centrality Measures — Degree centrality: how many other entities the query entity connects to within the document. Betweenness centrality: how often the query entity sits on the shortest path between other entity pairs in the document...
Centrality As A Reranking Layer — Initial retrieval still relies on standard text-matching to fetch a candidate pool. Centrality is applied as a reranking layer on the candidates, lifting those where the query entity drives the document’s structure...

The implementation rests on specific components and data structures.
Constructing The Document Entity Graph — Each document is parsed for entity mentions and relationships. The mentions become nodes; the relationships (often inferred from grammatical patterns: subject-verb-object, possessive constructions, prepositional phrases) become edges. Centrality is...

What This Means for SEO
What This Means for SEO
Centrality reranking makes structural ‘aboutness’ the deciding signal, so the strongest pages are organized around their entity, not around their keyword.
Build Pages Around The Entity Graph — A page on an entity should naturally introduce its related entities (its category, its makers, its related concepts) and connect them. The denser the local entity graph, the higher the centrality score.
One Entity Per Page — A page that tries to be central for several entities ends up central for none. Splitting a multi-entity piece into focused entity pages typically improves all of them.
Centrality Reranking Hurts Mention-Rich Pages — A page that lists many entities without making any of them central loses on entity queries. Listicles need a structural commitment to a primary entity to capture centrality bonus.
