Guess the radical efficiency didn't carry over to their web server
Sounds like marketing BS. what about OpenNLP and Stanford's for NLP?
Stanford CoreNLP give good accuracy and is pretty much the benchmark in English for accuracy. BUT it isn't great software. It falls over if you pass large amounts of text to it, the code is dreadful, it's hard to integrate (even in Java because of its own wacky config system), various parts aren't integrated (eg, SUTime), it doesn't have an embedding representation and it is pretty slow.
Having said all that I still use it sometimes. But Spacy is much nicer to use, and 99% (probably more) of the time the slightly lower accuracy is offset by things like the easy availability of word embedding right with the word tags.
I think it's pretty fair to say Spacy is the leading open-source NLP tool.
Agreed, the description is definitely cringe-worthy.
As if whoever wrote that wasn't aware that these are language geeks they're marketing to.
It's just that, wording-wise "the leading open source X" exudes marketing-speak, which I find language geeks tend to have robust antibodies against.
This kind of lingo work (sort of) for the market, say, MongoDB is in. But for the users of these tools, I suspect not so much.
In other words: Spacy is sinking.
