Spacy

spaCy is a powerful and efficient open-source Natural Language Processing (NLP) library written in Python, designed for building real-world text processing applications such as information extraction, text classification, and language understanding.

The library provides pre-trained models and supports tasks like tokenization, part-of-speech tagging, named entity recognition (NER), dependency parsing, and text classification. It is widely used by developers, data scientists, and AI engineers for building scalable NLP pipelines.

Features of spaCy:

• Fast and production-ready NLP processing.
• Pre-trained models for multiple languages.
• Named Entity Recognition (NER) and Part-of-Speech tagging.
• Dependency parsing and syntactic analysis.
• Easy integration with Python-based ML pipelines.
• Supports custom model training and pipelines.
