This package provides monad-like implementation for for the following Latent Semantic Analysis (LSA) main sequence of steps :
- ingesting a collection of documents;
- creating a document-term matrix (linear vector space representation);
- facilitating term-paragraph matrix creation or other breakdowns;
- apply different type of term-weighting functions;
- extract topics using NNMF (or SVD) with required parameters;
- provide topic interpretation;
- produce corresponding statistical thesauri;
- provide different statistics over the document collection.
