9 Best Natural Language Processing with Python Libraries in 2025

Natural language processing with Python (NLP) resides at the crossroads of data science and artificial intelligence (AI), fundamentally aimed at enabling machines to comprehend human languages and derive meaning from textual content.

Numerous organizations’ growing interest in NLP stems from its potential to unlock various insights and solutions for language-based challenges that consumers may encounter with products.

Given the complexity of NLP, developers require the finest tools available to effectively apply NLP techniques and algorithms, thereby developing services proficient in processing natural languages.

I. Understanding Natural Language Processing (NLP)

Natural Language Processing with Python (NLP) is a branch of computer science and AI that enables computers to interpret, understand, and generate human language in written and spoken forms. It integrates computational linguistics, which involves rule-based modeling of human language, with advanced algorithms from statistical, machine learning, and deep learning disciplines.

NLP aims to allow computers to comprehend the full nuances of human language, including the intent and emotions conveyed by the speaker or writer. Applications of NLP include translating languages, executing voice commands, summarizing texts, and more, making it a cornerstone technology in both consumer applications like digital assistants and professional solutions aimed at improving business efficiency and productivity.

II. List of NLP Tools and Libraries in Python

1. The Natural Language Toolkit (NLTK)

The Natural Language Toolkit (NLTK) is a comprehensive library for Python Natural Language Processing designed to facilitate a wide range of tasks in NLP and machine learning, including classification, stemming, tagging parsing, semantic reasoning, and tokenization. As a crucial educational resource, it equips Python developers with foundational knowledge and tools, particularly those new to Natural Language Processing and machine learning.

Originating from the collaborative efforts of Steven Bird and Edward Loper at the University of Pennsylvania, the NLTK has been instrumental in pioneering NLP research and is now incorporated into academic syllabi worldwide, reflecting its significance and utility in the field.

Despite its broad applicability and versatility, the NLTK is recognized for its complexity and challenges in practical Natural Language Processing using Python, particularly due to its slower performance in rapid production environments and a steep learning curve. Nevertheless, it offers valuable resources, such as the NLTK book, to assist developers in understanding and navigating the intricacies of language processing tasks facilitated by the toolkit.

Use-case: Tokenization of text.

3. spaCy

spaCy is defined as a contemporary library illustrating an NLP Python example specifically engineered for production use. It distinguishes itself by its user accessibility compared to other Python NLP libraries, such as NLTK. It is renowned for providing the fastest syntactic parser currently available, enhancing its appeal for efficient processing.

Constructed using Cython, spaCy is noted for its exceptional speed and efficiency, marking it as a standout choice for performance-oriented tasks.

Despite its strengths, spaCy is recognized for its relatively limited language support, accommodating only seven languages. This characteristic is noted within the context of its comparison to other libraries. However, given the rising prominence of machine learning and NLP and spaCy’s increasing popularity, there is anticipation for expanding its language support in the foreseeable future.

Use-case: Dependency parsing of a sentence.
