SpaCy is a natural language processing library designed to integrate within the Python Machine Learning eco-system.
In 2015, independent researchers from Emory University and YahooYahoo! Labs showed that spaCy offered the fastest syntactic parser in the world and that its accuracy was within 1% of the best available (Choi et al., 2015). spaCy v2.0, released in 2017, is more accurate than any of the systems Choi et al. evaluated.
