Entity Relationships

Co-occurrence, chi-square, correspondence and association measures between entities.

Entity Relationships

The Entity Relationships widget.

Overview

Analyses how the values of an entity relate to each other (or to groups) via a co-occurrence/contingency table: a chi-square test, correspondence analysis (a 2-D map of associations), standardized residuals (over-/under-represented pairs) and association measures. Selecting cells/points outputs the underlying documents.

Inputs

  • Data (Table) — bibliographic data.

Outputs

  • Co-occurrence Matrix, Chi-square, Correspondence, Association Measures (Table).

  • Selected Documents (Table).

Controls

  • Entity — the entity analysed; Top N / Min frequency / Max items trim it.

  • Include only / Exclude (+ Regex include/exclude) — entity filters.

  • Visualisation — co-occurrence heatmap, correspondence map, or residuals.

  • Row proportion — show row-wise shares.

  • Over-represented (+) / Under-represented (−) — highlight residual direction.

  • Min |residual| — residual magnitude threshold.

  • Min edge weight — for the co-occurrence view.
