spaCy: Industrial-strength NLP
|
||
******************************
|
||
|
||
spaCy is a library for advanced natural language processing in Python and
|
||
Cython. spaCy is built on the very latest research, but it isn't researchware.
|
||
It was designed from day one to be used in real products. spaCy currently supports
|
||
English and German, as well as tokenization for Chinese, Spanish, Italian, French,
|
||
Portuguese, Dutch, Swedish and Hungarian. It's commercial open-source software,
|
||
released under the MIT license.

|
||
|
||
Install spaCy
|
||
=============
|
||
|
||
spaCy is compatible with 64-bit CPython 2.6+/3.3+ and runs on Unix/Linux, OS X
|
||
and Windows. Source packages are available via
|
||
`pip <https://pypi.python.org/pypi/spacy>`_. Please make sure that
|
||
you have a working build enviroment set up. See notes on Ubuntu, macOS/OS X and Windows
|
||
for details.
|
||
|
||
pip
|
||
---
|
||
|
||
When using pip it is generally recommended to install packages in a virtualenv to
|
||
avoid modifying system state:
|
||
|
||
.. code:: bash
|
||
|
||
pip install spacy
|
||
|
||
Python packaging is awkward at the best of times, and it's particularly tricky with
|
||
C extensions, built via Cython, requiring large data files. So, please report issues
|
||
as you encounter them.
|
||
|
||
Install model
|
||
=============
|
||
|
||
After installation you need to download a language model. Currently only models for
|
||
English and German, named ``en`` and ``de``, are available.
|
||
|
||
.. code:: bash
|
||
|
||
python -m spacy.en.download all
|
||
python -m spacy.de.download all
|
||
|
||
The download command fetches about 1 GB of data which it installs
|
||
within the ``spacy`` package directory.
|
||
|
||
Upgrading spaCy
|
||
===============
|
||
|
||
To upgrade spaCy to the latest release:
|
||
|
||
pip
|
||
---
|
||
|
||
.. code:: bash
|
||
|
||
pip install -U spacy
|
||
|
||
Sometimes new releases require a new language model. Then you will have to upgrade to
|
||
a new model, too. You can also force re-downloading and installing a new language model:
|
||
|
||
.. code:: bash
|
||
|
||
python -m spacy.en.download --force
|
||
|
||
Compile from source
|
||
===================
|
||
|
||
The other way to install spaCy is to clone its GitHub repository and build it from
|
||
source. That is the common way if you want to make changes to the code base.
|
||
|
||
You'll need to make sure that you have a development enviroment consisting of a
|
||
Python distribution including header files, a compiler, pip, virtualenv and git
|
||
installed. The compiler part is the trickiest. How to do that depends on your
|
||
system. See notes on Ubuntu, OS X and Windows for details.
|
||
|
||
.. code:: bash
|
||
|
||
# make sure you are using recent pip/virtualenv versions
|
||
python -m pip install -U pip virtualenv
|
||
|
||
# find git install instructions at https://git-scm.com/downloads
|
||
git clone https://github.com/explosion/spaCy.git
|
||
|
||
cd spaCy
|
||
virtualenv .env && source .env/bin/activate
|
||
pip install -r requirements.txt
|
||
pip install -e .
|
||
|
||
Compared to regular install via pip `requirements.txt <requirements.txt>`_
|
||
additionally installs developer dependencies such as cython.
|
||
|
||
Ubuntu
|
||
------
|
||
|
||
Install system-level dependencies via ``apt-get``:
|
||
|
||
.. code:: bash
|
||
|
||
sudo apt-get install build-essential python-dev git
|
||
|
||
macOS / OS X
|
||
------------
|
||
|
||
Install a recent version of `XCode <https://developer.apple.com/xcode/>`_,
|
||
including the so-called "Command Line Tools". macOS and OS X ship with Python
|
||
and git preinstalled.
|
||
|
||
Windows
|
||
-------
|
||
|
||
Install a version of `Visual Studio Express <https://www.visualstudio.com/vs/visual-studio-express/>`_
|
||
or higher that matches the version that was used to compile your Python
|
||
interpreter. For official distributions these are VS 2008 (Python 2.7),
|
||
VS 2010 (Python 3.4) and VS 2015 (Python 3.5).
|
||
|
||
Run tests
|
||
=========
|
||
|
||
spaCy comes with an extensive test suite. First, find out where spaCy is
|
||
installed:
|
||
|
||
.. code:: bash
|
||
|
||
python -c "import os; import spacy; print(os.path.dirname(spacy.__file__))"
|
||
|
||
Then run ``pytest`` on that directory. The flags ``--vectors``, ``--slow``
|
||
and ``--model`` are optional and enable additional tests:
|
||
|
||
.. code:: bash
|
||
|
||
# make sure you are using recent pytest version
|
||
python -m pip install -U pytest
|
||
|
||
python -m pytest <spacy-directory> --vectors --model --slow
|
||
|
||
Download model to custom location
|
||
=================================
|
||
|
||
You can specify where ``spacy.en.download`` and ``spacy.de.download`` download the language model
|
||
to using the ``--data-path`` or ``-d`` argument:
|
||
|
||
.. code:: bash
|
||
|
||
python -m spacy.en.download all --data-path /some/dir
|
||
|
||
|
||
If you choose to download to a custom location, you will need to tell spaCy where to load the model
|
||
from in order to use it. You can do this either by calling ``spacy.util.set_data_path()`` before
|
||
calling ``spacy.load()``, or by passing a ``path`` argument to the ``spacy.en.English`` or
|
||
``spacy.de.German`` constructors.
|
||

||
**⚠️ Backwards incompatibilities**
|
||
|
||
No changes to the public, documented API, but the previously undocumented language data and model initialisation processes have been refactored and reorganised. If you were relying on the ``bin/init_model.py`` script, see the new `spaCy Developer Resources <https://github.com/explosion/spacy-dev-resources>`_ repo. Code that references internals of the ``spacy.en`` or ``spacy.de`` packages should also be reviewed before updating to this version.
|
||
|
||

|
||
|
||
* **NEW:** `"Adding languages" <https://spacy.io/docs/usage/adding-languages>`_ workflow.
|
||
* **NEW:** `"Part-of-speech tagging" <https://spacy.io/docs/usage/pos-tagging>`_ workflow.
|
||
* **NEW:** `spaCy Developer Resources <https://github.com/explosion/spacy-dev-resources>`_ repo – scripts, tools and resources for developing spaCy.

* **NEW:** Official/documented `training APIs <https://github.com/explosion/spaCy/tree/master/examples/training>`_ and `GoldParse` class
|
||
* Download and use GloVe vectors by default
|
||
* Make it easier to load and unload word vectors
|
||
* Improved rule matching functionality
|
||
* Move basic data into the code, rather than the json files. This makes it simpler to use the tokenizer without the models installed, and makes adding new languages much easier.
|
||
* Replace file-system strings with ``Path`` objects. You can now load resources over your network, or do similar trickery, by passing any object that supports the ``Path`` protocol.
|
||
|
||
**⚠️ Backwards incompatibilities**
|
||
|
||
* The data_dir keyword argument of ``Language.__init__`` (and its subclasses ``English.__init__`` and ``German.__init__``) has been renamed to ``path``.
|
||
* Details of how the Language base-class and its sub-classes are loaded, and how defaults are accessed, have been heavily changed. If you have your own subclasses, you should review the changes.
|
||
* The deprecated ``token.repvec`` name has been removed.
|
||
* The ``.train()`` method of Tagger and Parser has been renamed to ``.update()``
|
||
* The previously undocumented ``GoldParse`` class has a new ``__init__()`` method. The old method has been preserved in ``GoldParse.from_annot_tuples()``.
|
||
* Previously undocumented details of the ``Parser`` class have changed.
|
||
* The previously undocumented ``get_package`` and ``get_package_by_name`` helper functions have been moved into a new module, ``spacy.deprecated``, in case you still need them while you update.
|
||
|
||
**🔴 Bug fixes**
|
||
|
||
* Fix ``get_lang_class`` bug when GloVe vectors are used.
|
||
* Fix Issue `#411 <https://github.com/explosion/spaCy/issues/411>`_: ``doc.sents`` raised IndexError on empty string.
|
||
* Fix Issue `#455 <https://github.com/explosion/spaCy/issues/455>`_: Correct lemmatization logic

2016-05-05 `v0.100.7 <https://github.com/explosion/spaCy/releases/tag/0.100.7>`_: *German!*
|
||
-------------------------------------------------------------------------------------------
|
||
|
||
spaCy finally supports another language, in addition to English. We're lucky
|
||
to have Wolfgang Seeker on the team, and the new German model is just the
|
||
beginning. Now that there are multiple languages, you should consider loading
|
||
spaCy via the ``load()`` function. This function also makes it easier to load extra
|
||
word vector data for English:
|
||
|
||
.. code:: python
|
||
|
||
import spacy
|
||
en_nlp = spacy.load('en', vectors='en_glove_cc_300_1m_vectors')
|
||
de_nlp = spacy.load('de')
|
||
|
||
To support use of the load function, there are also two new helper functions:
|
||
``spacy.get_lang_class`` and ``spacy.set_lang_class``. Once the German model is
|
||
loaded, you can use it just like the English model:
|
||
|
||
.. code:: python
|
||
|
||
doc = nlp(u'''Wikipedia ist ein Projekt zum Aufbau einer Enzyklopädie aus freien Inhalten, zu dem du mit deinem Wissen beitragen kannst. Seit Mai 2001 sind 1.936.257 Artikel in deutscher Sprache entstanden.''')
|
||
|
||
for sent in doc.sents:
|
||
print(sent.root.text, sent.root.n_lefts, sent.root.n_rights)
|
||
|
||
# (u'ist', 1, 2)
|
||
# (u'sind', 1, 3)
|
||
|
||
The German model provides tokenization, POS tagging, sentence boundary detection,
|
||
syntactic dependency parsing, recognition of organisation, location and person
|
||
entities, and word vector representations trained on a mix of open subtitles and
|
||
Wikipedia data. It doesn't yet provide lemmatisation or morphological analysis,
|
||
and it doesn't yet recognise numeric entities such as numbers and dates.
|
||
|
||
**Bugfixes**
|
||
|
||
* spaCy < 0.100.7 had a bug in the semantics of the ``Token.__str__`` and ``Token.__unicode__`` built-ins: they included a trailing space.
|
||
* Improve handling of "infixed" hyphens. Previously the tokenizer struggled with multiple hyphens, such as "well-to-do".
|
||
* Improve handling of periods after mixed-case tokens
|
||
* Improve lemmatization for English special-case tokens
|
||
* Fix bug that allowed spaces to be treated as heads in the syntactic parse
|
||
* Fix bug that led to inconsistent sentence boundaries before and after serialisation.
|
||
* Fix bug from deserialising untagged documents.

2016-03-08 `v0.100.6 <https://github.com/explosion/spaCy/releases/tag/0.100.6>`_: *Add support for GloVe vectors*
|
||
-----------------------------------------------------------------------------------------------------------------
|
||
|
||
This release offers improved support for replacing the word vectors used by spaCy.
|
||
To install Stanford's GloVe vectors, trained on the Common Crawl, just run:
|
||
|
||
.. code:: bash
|
||
|
||
sputnik --name spacy install en_glove_cc_300_1m_vectors
|
||
|
||
To reduce memory usage and loading time, we've trimmed the vocabulary down to 1m entries.
|
||
|
||
This release also integrates all the code necessary for German parsing. A German model
|
||
will be released shortly. To assist in multi-lingual processing, we've added a ``load()``
|
||
function. To load the English model with the GloVe vectors:
|
||
|
||
.. code:: python
|
||
|
||
spacy.load('en', vectors='en_glove_cc_300_1m_vectors')
|
||
|
||
2016-02-07 `v0.100.5 <https://github.com/explosion/spaCy/releases/tag/0.100.5>`_
|
||
--------------------------------------------------------------------------------
|
||
|
||
Fix incorrect use of header file, caused from problem with thinc
|
||
|
||
2016-02-07 `v0.100.4 <https://github.com/explosion/spaCy/releases/tag/0.100.4>`_: *Fix OSX problem introduced in 0.100.3*
|
||
-------------------------------------------------------------------------------------------------------------------------
|
||
|
||
Small correction to right_edge calculation
|
||
|
||
2016-02-06 `v0.100.3 <https://github.com/explosion/spaCy/releases/tag/0.100.3>`_
|
||
--------------------------------------------------------------------------------
|
||
|
||
Support multi-threading, via the ``.pipe`` method. spaCy now releases the GIL around the
|
||
parser and entity recognizer, so systems that support OpenMP should be able to do
|
||
shared memory parallelism at close to full efficiency.
|
||
|
||
We've also greatly reduced loading time, and fixed a number of bugs.
|
||
|
||
2016-01-21 `v0.100.2 <https://github.com/explosion/spaCy/releases/tag/0.100.2>`_
|
||
--------------------------------------------------------------------------------
|
||
|
||
Fix data version lock that affected v0.100.1
|
||
|
||
2016-01-21 `v0.100.1 <https://github.com/explosion/spaCy/releases/tag/0.100.1>`_: *Fix install for OSX*
|
||
-------------------------------------------------------------------------------------------------------
|
||
|
||
v0.100 included header files built on Linux that caused installation to fail on OSX.
|
||
This should now be corrected. We also update the default data distribution, to
|
||
include a small fix to the tokenizer.
|
||
|
||
2016-01-19 `v0.100 <https://github.com/explosion/spaCy/releases/tag/0.100>`_: *Revise setup.py, better model downloads, bug fixes*
|
||
----------------------------------------------------------------------------------------------------------------------------------
|
||
|
||
* Redo setup.py, and remove ugly headers_workaround hack. Should result in fewer install problems.
|
||
* Update data downloading and installation functionality, by migrating to the Sputnik data-package manager. This will allow us to offer finer grained control of data installation in future.
|
||
* Fix bug when using custom entity types in ``Matcher``. This should work by default when using the
|
||
``English.__call__`` method of running the pipeline. If invoking ``Parser.__call__`` directly to do NER,
|
||
you should call the ``Parser.add_label()`` method to register your entity type.
|
||
* Fix head-finding rules in ``Span``.
|
||
* Fix problem that caused ``doc.merge()`` to sometimes hang
|
||
* Fix problems in handling of whitespace
|
||
|
||
2015-11-08 `v0.99 <https://github.com/explosion/spaCy/releases/tag/0.99>`_: *Improve span merging, internal refactoring*
|
||
------------------------------------------------------------------------------------------------------------------------
|
||
|
||
* Merging multi-word tokens into one, via the ``doc.merge()`` and ``span.merge()`` methods, no longer invalidates existing ``Span`` objects. This makes it much easier to merge multiple spans, e.g. to merge all named entities, or all base noun phrases. Thanks to @andreasgrv for help on this patch.
|
||
* Lots of internal refactoring, especially around the machine learning module, thinc. The thinc API has now been improved, and the spacy._ml wrapper module is no longer necessary.
|
||
* The lemmatizer now lower-cases non-noun, noun-verb and non-adjective words.
|
||
* A new attribute, ``.rank``, is added to Token and Lexeme objects, giving the frequency rank of the word.
|
||
|
||
2015-11-03 `v0.98 <https://github.com/explosion/spaCy/releases/tag/0.98>`_: *Smaller package, bug fixes*
|
||
---------------------------------------------------------------------------------------------------------
|
||
|
||
* Remove binary data from PyPi package.
|
||
* Delete archive after downloading data
|
||
* Use updated cymem, preshed and thinc packages
|
||
* Fix information loss in deserialize
|
||
* Fix ``__str__`` methods for Python2
|
||
|
||
2015-10-23 `v0.97 <https://github.com/explosion/spaCy/releases/tag/0.97>`_: *Load the StringStore from a json list, instead of a text file*
|
||
-------------------------------------------------------------------------------------------------------------------------------------------
|
||
|
||
* Fix bugs in download.py
|
||
* Require ``--force`` to over-write the data directory in download.py
|
||
* Fix bugs in ``Matcher`` and ``doc.merge()``
|
||
|
||
2015-10-19 `v0.96 <https://github.com/explosion/spaCy/releases/tag/0.96>`_: *Hotfix to .merge method*
|
||
-----------------------------------------------------------------------------------------------------
|
||
|
||
* Fix bug that caused text to be lost after ``.merge``
|
||
* Fix bug in Matcher when matched entities overlapped
|
||
|
||
2015-10-18 `v0.95 <https://github.com/explosion/spaCy/releases/tag/0.95>`_: *Bugfixes*
|
||

* Reform encoding of symbols
|
||
* Fix bugs in ``Matcher``
|
||
* Fix bugs in ``Span``
