What is Natural Language Processing (NLP)? 

natural language processing

First thing first, Natural Language Processing is a ground of artificial intelligence. NLPs aim is to understand the semantic structure and meaning of the textual human languages.  

It's far exceptional explained as AI for speech and textual content, which means there are computer and human languages for verbal exchange in computer science and AI. It allows machines to study natural human languages. As a middle branch of data science, NLP offers information to text and textual content to information.   

When imposing the NLP method, we should understand the test data and other duties addressing automatic summarization, machine translation, and many others.  

A few applications of NLP right here are- 

  • Machine translation 
  • Speech and image identification 
  • Conversational agents 
  • Text summary 
  • Recommendation engine 
  • Sentiment analysis 
  • Noun phrase extraction

What are the Common Natural Language Processing Tasks?

Day by day, NLP is increasing its reach to us and the industry. As a result, there is a lot of textual data and greater scattered data, the ones we want to process.   

There are a couple of NLP activities, including tokenizing, text mining, text modeling, word stemming, text classification, lemmatization, POS tagging, chunking, stop phrase elimination, named entity recognition, sentiment & text analysis, abstract semantic, machine translation, and dialogue systems, to name a few. 

Top NLP Libraries Python has Introduced

NLP libraries' purpose is to simplify text processing; a google NLP library is sufficient for the transformation of loose text into established text sentences those machines can utilize. Within the same manner, NLP libraries have a smooth get API where the brand new and big algorithms are successfully used.   

Now it’s time to reveal the best Python NLP libraries for analyzing human language data text and their uses.

NLTK- Natural Language Toolkit 


Natural Language Toolkit has widely recognized as one of the top text processing libraries. This NLTK Python package is introduced for smooth language processing.   

Python NLTK is the most used Python NLP library, an open-source NLP library. POS tagging, phrase frequencies, NLTK sentiment analysis, etc. are the most powerful functions that it offers.   

NLTK's user-friendly interfaces provide more than 50 linguistics assistants such as WordNet, corpora, linguistic, etc. Where those textual content processing libraries are used for class, tokenization, stemming, and so forth.
