What is a lancaster stemmer in nltk

This recipe explains what is a lancaster stemmer in nltk

Recipe Objective

This recipe explains what is Lancaster Stemmer.

Build a Chatbot in Python from Scratch!

Step 1: Importing library

Let us first import the necessary libraries. We'll import nltk and LancasterStemmer from nltk.

import nltk
from nltk import LancasterStemmer

Step 2: Lancaster Stemmer

Lancaster Stemmer is the most aggressive stemming algorithm. It has an edge over other stemming techniques because it offers us the functionality to add our own custom rules in this algorithm when we implement this using the NLTK package. This sometimes results in abrupt results.

words = ['sincerely','electricity','roughly','ringing']
Lanc = LancasterStemmer()
for w in words:
print(w, " : ", Lanc.stem(w))
