Factorial Analysis
Conceptual structure map (MCA/PCA of terms) with clustering.
The Factorial Analysis widget.
Overview
The biblioshiny conceptual structure analysis: reduces a term × document
matrix to a low-dimensional factor space (MCA / CA / PCA) and clusters the terms,
producing a 2-D map of the field’s conceptual structure.
Inputs
Data (
Table) — bibliographic data.
Outputs
Embeddings (
Table) — term coordinates in the factor space.Clusters (
Table) — cluster assignment per term.
Controls
Field Selection — which terms (author/index keywords…).
N Terms / Min Doc Freq — vocabulary size and rarity cutoff.
DTM Method — how the document-term matrix is weighted.
DR Method + Components — dimensionality-reduction method and number of axes.
Method + N Clusters — clustering algorithm and cluster count.
Plot Type, Show term labels — display options.
