For sentiment analysis, NLTK has a built-in module,nltk.sentiment.vader, which uses a combination of lexical and grammatical heuristics and a statistical model trained on human-annotated data. Here’s a basic example of how you can perform sentiment analysis using NLTK: from nltk.sentiment import...

There are some rather popular implementations out there, in python(aneesha/RAKE) and node(waseem18/node-rake) but neither seemed to use the power ofNLTK. By making NLTK an integral part of the implementation I get the flexibility and power to extend it in other creative ways, if I see fi...
We then find the length of the sentences using the len() function, which gives us the number of sentences in the string. So in Python using the nltk module, we can tokenize strings either into words or sentences. We then simply use the len() function to find the number of ...
