spaCy Industrial-Strength Natural Language Processing in Python

What is spaCy?

spaCy is a prominent open-source software library designed for advanced Natural Language Processing (NLP), written in Python and Cython. It's built with a focus on practical application, enabling users to develop real products and derive meaningful insights from text data. Engineered for efficiency and ease of use, spaCy provides a simple API and is straightforward to install, respecting the developer's time. It excels particularly in large-scale information extraction tasks due to its high speed and careful memory management, making it suitable for processing extensive datasets like web dumps.

Since its inception in 2015, spaCy has become an industry standard, supported by a vast ecosystem including various plugins and integrations with common machine learning stacks. Users can build custom components and workflows tailored to specific needs. The library offers robust support for over 75 languages, featuring numerous pre-trained pipelines. Key functionalities encompass linguistically-motivated tokenization, named entity recognition (NER), part-of-speech (POS) tagging, dependency parsing, text classification, and more. Recent developments include the `spacy-llm` package, which integrates Large Language Models (LLMs) into structured NLP pipelines without requiring task-specific training data.
