Difference between NLP and text mining

Hi all,

Could anyone please tell me what is the difference between NLP and text mining? are both same?

Thank you.

To put it simply, Text Mining deals with the text itself, while NLP deals with the underlying/latent metadata.

For a sentence, “A major incarnation of the weather phenomenon known as El Nîno is gathering force in the Pacific Ocean.”

Answering questions like - frequency counts of words, length of the sentence, presence/absence of certain words etc. is text mining

NLP on the other hand allows you to answer questions like;

  • What is the sentiment?
  • What are the keywords? (using POS tagging & parsers)
  • What category of content it falls under?
  • Which are the entities in the sentence? And more

NLP in most cases needs a good understanding of statistics and Machine Learning. Text Mining is often a pre-cursor to NLP, depending on the use case obviously.

Hi @Manas_Ranjan_Kar,

Thanks for the answer. Just one more question on this. Is R good in doing the NLP?
Many materials available online were pertaining to text mining are python and others than R.

Thank you.

I personally code in Python, so the answer is going to be biased. :smile:

There are multiple NLP-oriented libraries like NLTK, textblob, gensim that have a huge community base (plus Python errors are easier to decode). NLP needs a good understanding of semantics/linguistics too. You should start off with this book, great for getting a core understanding of NLP. And this one if you decide to go with Python.

Good Luck !
