PKG=LNFr-lsa ARCH=i386 VERSION=0.63 SERIALNUM=001 NAME=R:lsa - Latent Semantic Analysis CATEGORY=misc,graphics,util,application EMAIL=developers@linofee.org VENDOR=LINOFEE, http://www.linofee.org BASEDIR=/opt DESC=R library: 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.
