spaCy is a **free, open-source library** for advanced **Natural Language Processing** (NLP) in Python. If you're working with a lot of text, you'll eventually want to know more about it. For example, what's it about? What do the words mean in context? Who is doing what to whom? What companies and products are mentioned? Which texts are similar to each other? spaCy is designed specifically for **production use** and helps you build applications that process and "understand" large volumes of text. It can be used to build **information extraction** or **natural language understanding** systems, or to pre-process text for **deep learning**.

Unlike a platform, spaCy does not provide a software as a service, or a web application. It's an open-source library designed to help you build NLP applications, not a consumable service. - **spaCy is not an out-of-the-box chat bot engine**. While spaCy can be used to power conversational applications, it's not designed specifically for chat bots, and only provides the underlying text processing capabilities. - **spaCy is not research software**. It's built on the latest research, but it's designed to get things done. This leads to fairly different design decisions than [NLTK](https://github.com/nltk/nltk) or [CoreNLP](https://stanfordnlp.github.io/CoreNLP/), which were created as platforms for teaching and research. The main difference is that spaCy is integrated and opinionated. spaCy tries to avoid asking the user to choose between multiple algorithms that deliver equivalent functionality. Keeping the menu small lets spaCy deliver generally better performance and developer experience.M - **spaCy is not a company**. It's an open-source library. Our company publishing spaCy and other software is called [Explosion AI](https://explosion.ai). ## Features {#features} In the documentation, you'll come across mentions of spaCy's features and capabilities. Some of them refer to linguistic concepts, while others are related to more general machine learning functionality. | Name | Description | | ------------------------------------- | ------------------------------------------------------------------------------------------------------------------ | | **Tokenization** | Segmenting text into words, punctuations marks etc. | | **Part-of-speech** (POS) **Tagging** | Assigning word types to tokens, like verb or noun. | | **Dependency Parsing** | Assigning syntactic dependency labels, describing the relations between individual tokens, like subject or object. | | **Lemmatization** | Assigning the base forms of words. For example, the lemma of "was" is "be", and the lemma of "rats" is "rat". | | **Sentence Boundary Detection** (SBD) | Finding and segmenting individual sentences. | | **Named Entity Recognition** (NER) | Labelling named "real-world" objects, like persons, companies or locations. | | **Similarity** | Comparing words, text spans and documents and how similar they are to each other. | | **Text Classification** | Assigning categories or labels to a whole document, or parts of a document. | | **Rule-based Matching** | Finding sequences of tokens based on their texts and linguistic annotations, similar to regular expressions. | | **Training** | Updating and improving a statistical model's predictions. | | **Serialization** | Saving objects to files or byte strings. | ### Statistical models {#statistical-models} While some of spaCy's features work independently, others require [ statistical models](/models) to be loaded, which enable spaCy to **predict** linguistic annotations – for example, whether a word is a verb or a noun. spaCy currently offers statistical models for a variety of languages, which can be installed as individual Python modules. Models can differ in size, speed, memory usage, accuracy and the data they include. The model you choose always depends on your use case and the texts you're working with. For a general-purpose use case, the small, default models are always a good start. They typically include the following components: - **Binary weights** for the part-of-speech tagger, dependency parser and named entity recognizer to predict those annotations in context. - **Lexical entries** in the vocabulary, i.e. words and their context-independent attributes like the shape or spelling. - **Word vectors**, i.e. multi-dimensional meaning representations of words that let you determine how similar they are to each other. - **Configuration** options, like the language and processing pipeline settings, to put spaCy in the correct state when you load in the model. ## Linguistic annotations {#annotations} spaCy provides a variety of linguistic annotations to give you **insights into a text's grammatical structure**. This includes the word types, like the parts of speech, and how the words are related to each other. For example, if you're analyzing text, it makes a huge difference whether a noun is the subject of a sentence, or the object – or whether "google" is used as a verb, or refers to the website or company in a specific context. > #### Loading models > > ```bash > $ python -m spacy download en_core_web_sm > > >>> import spacy > >>> nlp = spacy.load("en_core_web_sm") > ``` Once you've [downloaded and installed](/usage/models) a model, you can load it via [`spacy.load()`](/api/top-level#spacy.load). This will return a `Language` object containing all components and data needed to process text. We usually call it `nlp`. Calling the `nlp` object on a string of text will return a processed `Doc`: ```python ### {executable="true"} import spacy nlp = spacy.load("en_core_web_sm") doc = nlp(u"Apple is looking at buying U.K. startup for $1 billion") for token in doc: print(token.text, token.pos_, token.dep_) ``` Even though a `Doc` is processed – e.g. split into individual words and annotated – it still holds **all information of the original text**, like whitespace characters. You can always get the offset of a token into the original string, or reconstruct the original by joining the tokens and their trailing whitespace. This way, you'll never lose any information when processing text with spaCy. ### Tokenization {#annotations-token} import Tokenization101 from 'usage/101/\_tokenization.md' To learn more about how spaCy's tokenization rules work in detail, how to **customize and replace** the default tokenizer and how to **add language-specific data**, see the usage guides on [adding languages](/usage/adding-languages) and [customizing the tokenizer](/usage/linguistic-features#tokenization). ### Part-of-speech tags and dependencies {#annotations-pos-deps model="parser"} import PosDeps101 from 'usage/101/\_pos-deps.md' To learn more about **part-of-speech tagging** and rule-based morphology, and how to **navigate and use the parse tree** effectively, see the usage guides on [part-of-speech tagging](/usage/linguistic-features#pos-tagging) and [using the dependency parse](/usage/linguistic-features#dependency-parse). ### Named Entities {#annotations-ner model="ner"} import NER101 from 'usage/101/\_named-entities.md' To learn more about entity recognition in spaCy, how to **add your own entities** to a document and how to **train and update** the entity predictions of a model, see the usage guides on [named entity recognition](/usage/linguistic-features#named-entities) and [training the named entity recognizer](/usage/training#ner). ### Word vectors and similarity {#vectors-similarity model="vectors"} import Vectors101 from 'usage/101/\_vectors-similarity.md' To learn more about word vectors, how to **customize them** and how to load **your own vectors** into spaCy, see the usage guide on [using word vectors and semantic similarities](/usage/vectors-similarity). ## Pipelines {#pipelines} import Pipelines101 from 'usage/101/\_pipelines.md' To learn more about **how processing pipelines work** in detail, how to enable and disable their components, and how to **create your own**, see the usage guide on [language processing pipelines](/usage/processing-pipelines). ## Vocab, hashes and lexemes {#vocab} Whenever possible, spaCy tries to store data in a vocabulary, the [`Vocab`](/api/vocab), that will be **shared by multiple documents**. To save memory, spaCy also encodes all strings to **hash values** – in this case for example, "coffee" has the hash `3197928453018144401`. Entity labels like "ORG" and part-of-speech tags like "VERB" are also encoded. Internally, spaCy only "speaks" in hash values. > - **Token**: A word, punctuation mark etc. _in context_, including its > attributes, tags and dependencies. > - **Lexeme**: A "word type" with no context. Includes the word shape and > flags, e.g. if it's lowercase, a digit or punctuation. > - **Doc**: A processed container of tokens in context. > - **Vocab**: The collection of lexemes. > - **StringStore**: The dictionary mapping hash values to strings, for example > `3197928453018144401` → "coffee". ![Doc, Vocab, Lexeme and StringStore](../images/vocab_stringstore.svg) If you process lots of documents containing the word "coffee" in all kinds of different contexts, storing the exact string "coffee" every time would take up way too much space. So instead, spaCy hashes the string and stores it in the [`StringStore`](/api/stringstore). You can think of the `StringStore` as a **lookup table that works in both directions** – you can look up a string to get its hash, or a hash to get its string: ```python ### {executable="true"} import spacy nlp = spacy.load("en_core_web_sm") doc = nlp(u"I love coffee") print(doc.vocab.strings[u"coffee"]) # 3197928453018144401 print(doc.vocab.strings[3197928453018144401]) # 'coffee' ``` > #### What does 'L' at the end of a hash mean? > > If you return a hash value in the **Python 2 interpreter**, it'll show up as > `3197928453018144401L`. The `L` just means "long integer" – it's **not** > actually a part of the hash value. Now that all strings are encoded, the entries in the vocabulary **don't need to include the word text** themselves. Instead, they can look it up in the `StringStore` via its hash value. Each entry in the vocabulary, also called [`Lexeme`](/api/lexeme), contains the **context-independent** information about a word. For example, no matter if "love" is used as a verb or a noun in some context, its spelling and whether it consists of alphabetic characters won't ever change. Its hash value will also always be the same. ```python ### {executable="true"} import spacy nlp = spacy.load("en_core_web_sm") doc = nlp(u"I love coffee") for word in doc: lexeme = doc.vocab[word.text] print(lexeme.text, lexeme.orth, lexeme.shape_, lexeme.prefix_, lexeme.suffix_, lexeme.is_alpha, lexeme.is_digit, lexeme.is_title, lexeme.lang_) ``` > - **Text**: The original text of the lexeme. > - **Orth**: The hash value of the lexeme. > - **Shape**: The abstract word shape of the lexeme. > - **Prefix**: By default, the first letter of the word string. > - **Suffix**: By default, the last three letters of the word string. > - **is alpha**: Does the lexeme consist of alphabetic characters? > - **is digit**: Does the lexeme consist of digits? | Text | Orth | Shape | Prefix | Suffix | is_alpha | is_digit | | ------ | --------------------- | ------ | ------ | ------ | -------- | -------- | | I | `4690420944186131903` | `X` | I | I | `True` | `False` | | love | `3702023516439754181` | `xxxx` | l | ove | `True` | `False` | | coffee | `3197928453018144401` | `xxxx` | c | fee | `True` | `False` | The mapping of words to hashes doesn't depend on any state. To make sure each value is unique, spaCy uses a [hash function](https://en.wikipedia.org/wiki/Hash_function) to calculate the hash **based on the word string**. This also means that the hash for "coffee" will always be the same, no matter which model you're using or how you've configured spaCy. However, hashes **cannot be reversed** and there's no way to resolve `3197928453018144401` back to "coffee". All spaCy can do is look it up in the vocabulary. That's why you always need to make sure all objects you create have access to the same vocabulary. If they don't, spaCy might not be able to find the strings it needs. ```python ### {executable="true"} import spacy from spacy.tokens import Doc from spacy.vocab import Vocab nlp = spacy.load("en_core_web_sm") doc = nlp(u"I love coffee") # Original Doc print(doc.vocab.strings[u"coffee"]) # 3197928453018144401 print(doc.vocab.strings[3197928453018144401]) # 'coffee' 👍 empty_doc = Doc(Vocab()) # New Doc with empty Vocab # empty_doc.vocab.strings[3197928453018144401] will raise an error :( empty_doc.vocab.strings.add(u"coffee") # Add "coffee" and generate hash print(empty_doc.vocab.strings[3197928453018144401]) # 'coffee' 👍 new_doc = Doc(doc.vocab) # Create new doc with first doc's vocab print(new_doc.vocab.strings[3197928453018144401]) # 'coffee' 👍 ``` If the vocabulary doesn't contain a string for `3197928453018144401`, spaCy will raise an error. You can re-add "coffee" manually, but this only works if you actually _know_ that the document contains that word. To prevent this problem, spaCy will also export the `Vocab` when you save a `Doc` or `nlp` object. This will give you the object and its encoded annotations, plus the "key" to decode it. ## Serialization {#serialization} import Serialization101 from 'usage/101/\_serialization.md' To learn more about how to **save and load your own models**, see the usage guide on [saving and loading](/usage/saving-loading#models). ## Training {#training} import Training101 from 'usage/101/\_training.md' To learn more about **training and updating** models, how to create training data and how to improve spaCy's named entity recognition models, see the usage guides on [training](/usage/training). ## Language data {#language-data} import LanguageData101 from 'usage/101/\_language-data.md' To learn more about the individual components of the language data and how to **add a new language** to spaCy in preparation for training a language model, see the usage guide on [adding languages](/usage/adding-languages). ## Lightning tour {#lightning-tour} The following examples and code snippets give you an overview of spaCy's functionality and its usage. ### Install models and process text {#lightning-tour-models} ```bash python -m spacy download en_core_web_sm python -m spacy download de_core_news_sm ``` ```python ### {executable="true"} import spacy nlp = spacy.load("en_core_web_sm") doc = nlp(u"Hello, world.

If you'd like to get involved, below are some answers to the most important questions and resources for further reading. ### Help, my code isn't working! {#faq-help-code} Bugs suck, and we're doing our best to continuously improve the tests and fix bugs as soon as possible. Before you submit an issue, do a quick search and check if the problem has already been reported. If you're having installation or loading problems, make sure to also check out the [troubleshooting guide](/usage/#troubleshooting). Help with spaCy is available via the following platforms: > #### How do I know if something is a bug? > > Of course, it's always hard to know for sure, so don't worry – we're not going > to be mad if a bug report turns out to be a typo in your code. As a simple > rule, any C-level error without a Python traceback, like a **segmentation > fault** or **memory error**, is **always** a spaCy bug. > > Because models are statistical, their performance will never be _perfect_. > However, if you come across **patterns that might indicate an underlying > issue**, please do file a report. Similarly, we also care about behaviors that > **contradict our docs**. - [Stack Overflow](https://stackoverflow.com/questions/tagged/spacy): **Usage questions** and everything related to problems with your specific code. The Stack Overflow community is much larger than ours, so if your problem can be solved by others, you'll receive help much quicker. - [Gitter chat](https://gitter.im/explosion/spaCy): **General discussion** about spaCy, meeting other community members and exchanging **tips, tricks and best practices**. - [GitHub issue tracker](https://github.com/explosion/spaCy/issues): **Bug reports** and **improvement suggestions**, i.e. everything that's likely spaCy's fault. This also includes problems with the models beyond statistical imprecisions, like patterns that point to a bug. Please understand that we won't be able to provide individual support via email. We also believe that help is much more valuable if it's shared publicly, so that **more people can benefit from it**. If you come across an issue and you think you might be able to help, consider posting a quick update with your solution. No matter how simple, it can easily save someone a lot of time and headache – and the next time you need help, they might repay the favor. ### How can I contribute to spaCy? {#faq-contributing} You don't have to be an NLP expert or Python pro to contribute, and we're happy to help you get started. If you're new to spaCy, a good place to start is the [`help wanted (easy)` label](https://github.com/explosion/spaCy/issues?q=is%3Aissue+is%3Aopen+label%3A"help+wanted+%28easy%29") on GitHub, which we use to tag bugs and feature requests that are easy and self-contained. We also appreciate contributions to the docs – whether it's fixing a typo, improving an example or adding additional explanations. You'll find a "Suggest edits" link at the bottom of each page that points you to the source. Another way of getting involved is to help us improve the [language data](/usage/adding-languages#language-data) – especially if you happen to speak one of the languages currently in [alpha support](/usage/models#languages). Even adding simple tokenizer exceptions, stop words or lemmatizer data can make a big difference. It will also make it easier for us to provide a statistical model for the language in the future. Submitting a test that documents a bug or performance issue, or covers functionality that's especially important for your application is also very helpful. This way, you'll also make sure we never accidentally introduce regressions to the parts of the library that you care about the most. **For more details on the types of contributions we're looking for, the code conventions and other useful tips, make sure to check out the [contributing guidelines](https://github.com/explosion/spaCy/tree/master/CONTRIBUTING.md).** spaCy adheres to the [Contributor Covenant Code of Conduct](http://contributor-covenant.org/version/1/4/).
