text2vec is an R package which provides an efficient framework with a concise API for text analysis and natural language processing (NLP).

Goals which we aimed to achieve as a result of development of text2vec:

Concise – expose as few functions as possible
Consistent – expose unified interfaces, no need to explore new interface for each task
Flexible – allow to easily solve complex tasks
Fast – maximize efficiency per single thread, transparently scale to multiple threads on multicore machines
Memory efficient – use streams and iterators, not keep data in RAM if possible
