Topic Terms Report

The Topic Terms report shows the terms that have the largest loadings in each topic after rotation. There are additional reports that show the components of the rotated singular value decomposition.

The report shows a table of terms for each topic. The terms in each table are the ones that have the largest loadings in absolute value for each topic. Each table is sorted in descending order by the absolute value of the loading. These tables can be used to determine conceptual themes that correspond to each topic.

The Topic Terms report also contains the following matrix reports:

Variance Explained by Each Topic

Contains a table of the variance explained by each topic. The table also contains columns for the percent and cumulative percent of the variation explained by each topic.

Term Topic Loadings

Contains a matrix of the loadings across topics for each term. This matrix is equivalent to the transpose of the factor loading matrix in a rotated PCA.

Document Topic Scores

Contains a matrix of document scores for each topic. Documents with higher scores in a topic are more likely to be associated with that topic.

Rotation Matrix

Contains the rotation matrix for the varimax rotation.
