spaCy
NLP (Natural Language Processing)
Industrial-strength NLP in Python.
📖 spaCy Overview
spaCy is an industrial-strength, open-source NLP library written in Python that enables developers and data scientists to process and understand human language efficiently. Unlike many research-focused NLP tools, spaCy is designed for production use, offering fast, reliable, and easy-to-integrate solutions for real-world applications. It supports tokenization, part-of-speech tagging, syntactic parsing, named entity recognition, and more, all wrapped in a smooth pipeline.
🛠️ How to Get Started with spaCy
Install spaCy easily via pip:
pip install spacy
Download a pretrained model for your language, e.g., English:
python -m spacy download en_core_web_sm
Load the model and process text with just a few lines of Python code:
import spacy
nlp = spacy.load("en_core_web_sm")
doc = nlp("Apple is looking at buying U.K. startup for $1 billion.")
for token in doc:
print(token.text, token.pos_, token.dep_)
for ent in doc.ents:
print(ent.text, ent.label_)
