Description

spaCy is an open-source software library for advanced Natural Language Processing (NLP), written in Python and Cython. Designed with a focus on practical application, it helps users build real products and gather insights efficiently. It boasts high performance, making it suitable for large-scale information extraction and processing extensive text data like web dumps, leveraging carefully memory-managed Cython implementation.

Since its initial release in 2015, spaCy has become an industry standard supported by a large ecosystem of plugins and integrations. It supports features like linguistically-motivated tokenization, named entity recognition, part-of-speech tagging, dependency parsing, and more across over 75 languages. The library includes pretrained pipelines, supports custom models from frameworks like PyTorch and TensorFlow, and offers tools for training, deployment, and workflow management, including integration with Large Language Models (LLMs).
