SpaCy is an open-source library designed for advanced natural language processing (NLP) in Python. It provides tools for tasks such as tokenization, part-of-speech tagging, named entity recognition, and dependency parsing. SpaCy is known for its speed and efficiency, making it suitable for both research and production environments. Developed by Explosion AI, SpaCy supports multiple languages and integrates well with other machine learning frameworks. It is widely used in applications like chatbots, information extraction, and text classification, helping developers create intelligent systems that understand human language more effectively.
