spaCy NLP Tokenizer and Lexicon
|
|
================================
|
|
|
|
spaCy is a library for industrial strength NLP in Python. Its core
|
|
values are:
|
|
|
|
* **Efficiency**: You won't find faster NLP tools. For shallow analysis, it's 10x
|
|
faster than Stanford Core NLP, and over 200x faster than NLTK. Its parser is
|
|
over 100x faster than Stanford's.
|
|
|
|
* **Accuracy**: All spaCy tools are within 0.5% of the current published
|
|
state-of-the-art, on both news and web text. NLP moves fast, so always check
|
|
the numbers --- and don't settle for tools that aren't backed by
|
|
rigorous recent evaluation.
|
|
|
|
* **Minimalism**: This isn't a library that covers 43 known algorithms to do X. You
|
|
get 1 --- the best one --- with a simple, low-level interface. This keeps the
|
|
code-base small and concrete. Our Python APIs use lists and
|
|
dictionaries, and our C/Cython APIs use arrays and simple structs.
