+h2 Built for Production
|
|
|
|
p.text-big.
|
|
Most AI software is built for research. Over the last ten years,
|
|
we've used a lot of that software, and built some of it ourselves,
|
|
especially for natural language processing (NLP).
|
|
But the faster the research has moved, the more impatient we've
|
|
become. We want to see advanced NLP technologies get out into
|
|
great products, as the basis of great businesses. We built spaCy
|
|
to make that happen.
|
|
|
|
+h2 Easy and Powerful
|
|
|
|
p.text-big.
|
|
For any NLP task, there are always lots of competing algorithms.
|
|
We don't believe in implementing them all and letting you choose.
|
|
Instead, we just implement one – the best one.
|
|
When better algorithms are developed, we can update the library without
|
|
breaking your code or bloating the API. This approach makes spaCy
|
|
both #[strong easier] and #[strong more powerful] than a pluggable
|
|
architecture. spaCy also features a #[strong unique whole-document design].
|
|
Where other NLP libraries rely on sentence detection as
|
|
a pre-process, spaCy reads the whole document at once, making it much more
|
|
robust to informal and poorly formatted text.
|
|
|
|
+h2 Permissive open-source license (MIT)
|
|
p.text-big.
|
|
We think spaCy is valuable software, so we made it free, to raise
|
|
its value even higher.
|
|
Making spaCy open-source puts us on the same side –
|
|
we can tell you everything about how it works, and let
|
|
you run it however you like. We think the software would be much
|
|
less valuable as a service, which could disappear at any point.

.h2 What we do
|
|
|
|
p.text-big spaCy helps you write programs that do clever things with text. You give it a string of characters, it gives you an object that provides multiple useful views of its meaning and linguistic structure. Specifically, spaCy features a high performance tokenizer, part-of-speech tagger, named entity recognizer and syntactic dependency parser, with built-in support for word vectors. All of the functionality is united behind a clean high-level Python API, that makes it easy to use the different annotations together.
|
|
|
|
p.text-big To make spaCy as fast and easy to install as we could, we built it #[strong from the ground up] from custom components, with #[strong custom implementations], and sometimes #[strong custom algorithms]. It's written in clean but efficient Cython code, which allows us to manage both low level details and the high-level Python API in a single codebase.

|
|
.h2 State-of-the-art speed and accuracy
|
|
|
|
p.text-big spaCy is committed to rigorous evaluation under standard methodology. Two peer-reviewed papers in 2015 confirm that it offers the #[strong fastest syntactic parser in the world] and that #[strong its accuracy is within 1% of the best] available. The few systems that are more accurate are 20× slower or more.
|
|
|
|
p.text-big The first of the evaluations was published by #[strong Yahoo! Labs] and #[strong Emory University], as part of a survey of current parsing technologies #[a(href="http://aclweb.org/anthology/P/P15/P15-1038.pdf" target="_blank") (Choi et al., 2015)]. Their results and subsequent discussions helped us develop a novel psychologically-motivated technique to improve spaCy's accuracy, which we published in joint work with Macquarie University #[a(href="https://aclweb.org/anthology/D/D15/D15-1162.pdf" target="_blank") (Honnibal and Johnson, 2015)].
