Thematic Map

Strategic diagram of keyword clusters (centrality × density quadrants).

Thematic Map

The Thematic Map widget.

Overview

Builds the biblioshiny-style thematic (strategic) map: keywords are clustered from their co-occurrence network and each cluster is placed by centrality (relevance/links to other themes, x-axis) and density (internal development, y-axis), giving the four quadrants — motor, niche, emerging/declining and basic themes. Clicking a cluster outputs its documents.

Inputs

  • Data (Table) — bibliographic data.

Outputs

  • Thematic Data (Table) — per-cluster centrality/density and members.

  • Selected Documents (Table) — documents of the selected cluster.

  • Network (Table) — the underlying co-occurrence edges.

Controls

  • Field — which terms to map (author/index keywords…).

  • Min Occurrences — drop rare terms before clustering.

  • Top N Items — keep the N most frequent terms.

  • Synonyms (Merge Items) — thesaurus rules to merge term variants (separator ;).

  • Auto apply — recompute on change.
