+ "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.")
