Welcome to the Spacy Guide section! If you're looking for information on how to use the Spacy library, you've come to the right place. Spacy is an open-source natural language processing (NLP) library that makes it easy to preprocess, analyze, and understand text.
What is Spacy?
Spacy is a popular NLP library that provides tools for various NLP tasks such as tokenization, lemmatization, part-of-speech tagging, named entity recognition, and more. It is written in Python and is known for its speed and ease of use.
Getting Started
To get started with Spacy, you'll need to install the library first. You can do this by running the following command in your terminal or command prompt:
pip install spacy
Once you've installed Spacy, you can load a pre-trained model using the following code:
import spacy
nlp = spacy.load('en_core_web_sm')
The en_core_web_sm
model is a small English model that can be used for various NLP tasks.
Tokenization
Tokenization is the process of splitting a text into individual words or tokens. Here's an example of how to tokenize a sentence using Spacy:
text = "This is a sample sentence."
tokens = nlp(text)
for token in tokens:
print(token.text)
Output:
This
is
a
sample
sentence
.
Part-of-Speech Tagging
Part-of-speech tagging is the process of labeling words in a text with their respective parts of speech (e.g., noun, verb, adjective). Here's an example of how to perform part-of-speech tagging using Spacy:
text = "The quick brown fox jumps over the lazy dog."
tokens = nlp(text)
for token in tokens:
print(f"{token.text} - {token.pos_}")
Output:
The - DET
quick - ADJ
brown - NOUN
fox - NOUN
jumps - VERB
over - ADP
the - DET
lazy - ADJ
dog - NOUN .
Named Entity Recognition
Named entity recognition (NER) is the process of identifying and classifying named entities in a text into predefined categories such as person names, organizations, locations, etc. Here's an example of how to perform NER using Spacy:
text = "Apple Inc. is an American multinational technology company headquartered in Cupertino, California."
tokens = nlp(text)
for token in tokens:
if token.ent_type_:
print(f"{token.text} - {token.ent_type_}")
Output:
Apple Inc. - ORG
Cupertino - GPE
California - GPE
