💎 ruby-spacy
Overview
ruby-spacy is a wrapper module for using spaCy from the Ruby programming language via PyCall. This module aims to make it easy and natural for Ruby programmers to use spaCy. This module covers the areas of spaCy functionality for using many varieties of its language models, not for building ones.
Functionality | |
---|---|
✅ | Tokenization, lemmatization, sentence segmentation |
✅ | Part-of-speech tagging and dependency parsing |
✅ | Named entity recognition |
✅ | Syntactic dependency visualization |
✅ | Access to pre-trained word vectors |
✅ | OpenAI Chat/Completion/Embeddings API integration |
Current Version: 0.2.3
- spaCy 3.7.0 supported
- OpenAI API integration
Installation of Prerequisites
IMPORTANT: Make sure that the enable-shared
option is enabled in your Python installation. You can use pyenv to install any version of Python you like. Install Python 3.10.6, for instance, using pyenv with enable-shared
as follows:
$ env CONFIGURE_OPTS="--enable-shared" pyenv install 3.10.6
Remember to make it accessible from your working directory. It is recommended that you set global
to the version of python you just installed.
$ pyenv global 3.10.6
Then, install spaCy. If you use pip
, the following command will do:
$ pip install spacy
Install trained language models. For a starter, en_core_web_sm
will be the most useful to conduct basic text processing in English. However, if you want to use advanced features of spaCy, such as named entity recognition or document similarity calculation, you should also install a larger model like en_core_web_lg
.
$ python -m spacy download en_core_web_sm
$ python -m spacy download en_core_web_lg
See Spacy: Models & Languages for other models in various languages. To install models for the Japanese language, for instance, you can do it as follows:
$ python -m spacy download ja_core_news_sm
$ python -m spacy download ja_core_news_lg
Installation of ruby-spacy
Add this line to your application's Gemfile:
gem 'ruby-spacy'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install ruby-spacy
Usage
See Examples below.
Examples
Many of the following examples are Python-to-Ruby translations of code snippets in spaCy 101. For more examples, look inside the examples
directory.

OpenAI API Integration
⚠️ This feature is currently experimental. Details are subject to change. Please refer to OpenAI's API reference and Ruby OpenAI for available parameters (
max_tokens
,temperature
, etc).
Easily leverage GPT models within ruby-spacy by using an OpenAI API key. When constructing prompts for the Doc::openai_query
method, you can incorporate the following token properties of the document. These properties are retrieved through function calls (made internally by GPT when necessary) and seamlessly integrated into your prompt. Note that function calls need gpt-4o-mini
or greater. The available properties include:
surface
lemma
tag
-
pos
(part of speech) -
dep
(dependency) -
ent_type
(entity type) morphology
GPT Prompting (Translation)

# default parameter values
# max_tokens: 1000
# temperature: 0.7
# model: "gpt-4o-mini"
res1 = doc.openai_query(
access_token: api_key,
prompt: "Translate the text to Japanese."
)
puts res1
Output:
ビートルズは12枚のスタジオアルバムをリリースしました。

Vladimir Nabokov was a Russian-American novelist, poet, and entomologist, best known for his intricate prose style and innovative narrative techniques. He is most famously recognized for his controversial novel "Lolita," which explores themes of obsession and manipulation. Nabokov's works often reflect his fascination with language, memory, and the nature of art. In addition to his literary accomplishments, he was also a passionate lepidopterist, contributing to the field of butterfly studies. His literary career spanned several decades, and his influence continues to be felt in contemporary literature.
