%description
Fast and memory-friendly tools for text vectorization, topic modeling
(LDA, LSA), word embeddings (GloVe), similarities. This package provides a
source-agnostic streaming API, which allows researchers to perform
analysis of collections of documents which are larger than available RAM.
All core functions are parallelized to benefit from multicore machines.
