In this article, we have given information about 8 top NLP
libraries present in the python language. Every library has a unique property.
1.Natural Language Toolkit (NLTK)
I. The library was developed by Steven Bird and Edward
Loper at the University of Pennsylvania and played a key role in breakthrough
II. Nowadays many universities around the globe now use NLTK,
Python libraries, and other tools in their courses.
III. It's basically your main tool for natural language processing and
IV. NLTK is an essential library that supports tasks such as classification, stemming, tagging, parsing, semantic reasoning, and tokenization in Python
V. Today it serves as an educational foundation for Python developers who
are dipping their toes in this field (and machine learning).
VI. This library is pretty versatile, but we must admit that it's also quite difficult to use for Natural Language Processing with Python.
VII.NLTK can be rather slow and doesn't match the demands of quick-paced production usage.
VIII. The learning curve is steep, but developers can take advantage of resources to learn more about the concepts behind the language processing tasks this toolkit supports.
I.TextBlob is a must for developers who are starting
their journey with NLP in Python and want to make the most of their first
encounter with NLTK.
II. It basically provides beginners with an easy interface to help them learn most basic NLP tasks like sentiment analysis,pos-tagging, or noun phrase extraction.
III. We believe anyone who wants to make their first steps toward NLP with Python should use this library.
IV. It's very helpful in designing prototypes. However, it also inherited the main flaws of NLTK its just too slow to help developers who face the demands of NLP Python production usage.
I. This library was developed at Stanford University and it's written in Java. Still, its equipped with wrappers for many different languages, including Python.
II. That's why it can be useful for developers interested in trying their hand at natural language processing in Python.
III. What is the greatest advantage of CoreNLP?
IV. The library is really fast and works well in product development environments,. Moreover, some of CoreNLP components can be integrated with NLTK which is bound to boost the efficiency of the latter.
I. Gensim is a Python library that specializes in identifying semantic similarity between two documents through vector space modeling and topic modeling toolkit.
II. It can handle large text corpora with the help of efficiency data streaming and incremental algorithms, which is more than we can say about other packages that only target batch and in-memory processing.
III. What we love about it are its incredible memory usage optimization and processing speed. These were achieved with the help of another Python library, NumPy.
IV. The tools vector space modeling capabilities are also top-notch.
I. spaCy is a relatively young library was designed for production usage. That's why it's so much more accessible than other Python NLP libraries like NLTK.
II. spaCy offers the fastest syntactic parser available on the market today.
III. Moreover, since the toolkit is written in Cython, it's also really speedy and efficient.
IV. However, no tool is perfect. In comparison to the libraries we covered so far, spaCy supports the smallest number of languages(seven).
V. However, the growing popularity of machine learning, NLP, and spaCy as a key library means that the tool might start supporting more programming languages soon.
I. This slightly lesser-known library is one of our favorites because it offers a broad range of analysis and impressive language coverage.
II. Thanks to NumPy, it also works really fast. Using polyglot is similar to spaCy.
III. it's very efficient, straightforward, and basically an excellent choice for projects involving a language spaCy doesn't support.
IV. The library stands out from the crowd also because it requests the usage of a dedicated command in the command line through the pipeline mechanisms. Definitely worth a try.
I. This handy NLP library provides developers with a wide range of algorithms for building machine learning models.
II. It offers many functions for using the bag-of-words method of creating features to tackle text classification problems.
III. The strength of this library is the intuitive class methods. Also, scikit-learn has excellent documentation that helps developers make the most of its features.
IV. However, the library doesn't use neural networks for text preprocessing. So if you'd like to carry out more complex preprocessing tasks like POS tagging for your text corpora, it's better to use other NLP libraries and then return to scikit-learn for building your models.
I. Another gem in the NLP libraries Python developers uses to handle natural languages.
II. The pattern allows part-of-speech tagging, sentiment analysis, vector space modeling, SVM, clustering, n-gram search, and WordNet.
III. You can take advantage of a DOM parser, a web crawler, as well as some useful APIs like Twitter or Facebook.
IV. Still, the tool is essentially a web miner and might not be enough for completing other natural language processing tasks.
We can use different NLP libraries for different purposes in python also in machine learning projects.
