Bibliographic Coupling

Papers linked by shared references (research-front structure).

The Bibliographic Coupling widget.

Overview

Builds the bibliographic-coupling network: two papers are linked when they cite the same references — the more shared references, the stronger the link. Whereas co-citation reveals the historical base, coupling reveals the current research front (clusters of papers working on related problems now).

Inputs

• Data (Table) — OpenAlex-enriched data (referenced works).

Outputs

• Node Data (Table) — papers with degree and community.

• Edge Data (Table) — coupling edges (shared-reference weight).

Controls

• Paper ID col / References col — the identifier and references columns.

• Min shared refs — minimum shared references for an edge.

• Top N papers — cap the number of papers.

Actions: Build.
