v2.0.0: Neural networks, 13 new models for 7+ languages, better training, custom pipelines, Pickle & lots of API improvements

We're very excited to finally introduce spaCy v2.0. The new version gets spaCy up to date with the latest deep learning technologies and makes it much easier to run spaCy in scalable cloud computing workflows. We've fixed over 60 bugs (every open bug!), including several long-standing issues, trained 13 neural network models for 7+ languages and added alpha tokenization support for 8 new languages. We also re-wrote almost all of the usage guides, API docs and code examples.

pip install -U spacy

conda install -c conda-forge spacy

✨ Major features and improvements

• NEW: Convolutional neural network models for English, German, Spanish, Portuguese, French, Italian, Dutch and multi-language NER. Substantial improvements in accuracy over the v1.x models.
• NEW: Vectors class for managing word vectors, plus trainable document vectors and contextual similarity via convolutional neural networks.
• NEW: Custom processing pipeline components and extension attributes on the Doc, Token and Span via Doc._, Token._ and Span._.
• NEW: Built-in, trainable text classification pipeline component.
• NEW: Built-in displaCy visualizers for dependencies and entities, with Jupyter notebook support.
• NEW: Alpha tokenization for Danish, Polish, Indonesian, Thai, Hindi, Irish, Turkish, Croatian and Romanian.
• Improved language data, support for lazy loading and simple, lookup-based lemmatization for English, German, French, Spanish, Italian, Hungarian, Portuguese and Swedish.
• Support for multi-language models and new MultiLanguage class (xx).
• Strings are now resolved to hash values, instead of mapped to integer IDs. This means that the string-to-int mapping no longer depends on the vocabulary state.
• Improved and consistent saving, loading and serialization across objects, plus Pickle support.
• PhraseMatcher for matching large terminology lists as Doc objects, plus revised Matcher API.
• New CLI commands validate, vocab and evaluate, plus entry point for spacy command to use instead of python -m spacy.
• Experimental GPU support via Chainer's CuPy module.

🔮 Models

spaCy v2.0 comes with 13 new convolutional neural network models for 7+ languages. The models have been designed and implemented from scratch specifically for spaCy. A novel bloom embedding strategy with subword features is used to support huge vocabularies in tiny tables.

All core models include part-of-speech tags, dependency labels and named entities. Small models include only context-specific token vectors, while medium-sized and large models ship with word vectors. For more details, see the models directory or try our new model comparison tool.

You can download a model by using its name or shortcut. To load a model, use spacy.load(), or import it as a module and call its load() method:

spacy download en_core_web_sm

import spacy
nlp = spacy.load('en_core_web_sm')

import en_core_web_sm
nlp = en_core_web_sm.load()

📈 Benchmarks

spaCy v2.0's new neural network models bring significant improvements in accuracy, especially for English Named Entity Recognition. The new en_core_web_lg model makes about 25% fewer mistakes than the corresponding v1.x model and is within 1% of the current state-of-the-art (Strubell et al., 2017). The v2.0 models are also cheaper to run at scale, as they require under 1 GB of memory per process.
