MonadicLatent
Software monad for Latent semantic analysis
Contributed by: Anton Antonov
Software monad for Latent Semantic Analysis (LSA). Three dimension reduction algorithms are supported Singular Value Decomposition (SVD), Non-Negative Matrix Factorization (NNMF), Independent Component Analysis (ICA).
Installation Instructions

Details
In this paclet the concept "software monad" is seen as a design pattern, suitable for rapid and dynamic building of computational workflows.
The monadic pipelines can be constructed with the douple right arrow symbol, "⟹".
The monad has functions for document-term matrix construction.
The entries of the document-term matrices can be adjusted with typical Latent Semantic Indexing (LSI) weight functions (IDF, TFIDF, Cosine, etc.)
The monad has functions fo extracting and tabulating topics and statistical thesauri.
The monad has functions for graph reprsentations of the document-term matrices and document-topic matrices.
