(synopsis "Latent semantic analysis")
(description
"The basic idea of latent semantic analysis (LSA) is, that text do have a
higher order (=latent semantic) structure which, however, is obscured by word
usage (e.g. through the use of synonyms or polysemy). By using conceptual
indices that are derived statistically via a truncated singular value
decomposition (a two-mode factor analysis) over a given document-term matrix,
this variability problem can be overcome.")
