Description

Typical singular values of a term-document matrix based on encyclopedia articles.

Usage

DSM_SingularValues

Format

A numeric vector of length 2623.

Details

The data were obtained by singular value decomposition of a term-document matrix representing 100,000 Wikipedia articles, with 2623 target terms from a Basic English vocabulary. Articles were truncated to the first ca. 500 words. Occurrence frequencies of the target terms were log-scaled and rows of the matrix were L2-normalized before applying the SVD.

Examples

plot(DSM_SingularValues, type="h", xaxs="i", yaxs="i")
