Gensim began as a "a collection of various Python scripts for the Czech Digital Mathematics Library in 2008, where it served to generate a short list of the most similar articles to a given article". Gensim was created to address the challenges of efficiency, scalability, and computation power in this library system. Gensim is "the most robust, efficient and hassle-free piece of software to realize unsupervised semantic modelling from plain text. It stands in contrast to brittle homework-assignment-implementations that do not scale on one hand, and robust java-esque projects that take forever just to run “hello world”". Gensim is a robust, open-source, platform independent software.
