How To Install python-stemmer on Ubuntu 20.04

In this tutorial we learn how to install python-stemmer on Ubuntu 20.04. python-stemmer is Python bindings for libstemmer - snowball stemming algorithms

Introduction

In this tutorial we learn how to install python-stemmer on Ubuntu 20.04.

What is python-stemmer

python-stemmer is:

PyStemmer provides access to efficient algorithms for calculating a “stemmed” form of a word. This is a form with most of the common morphological endings removed; hopefully representing a common linguistic base form. This is most useful in building search engines and information retrieval software; for example, a search with stemming enabled should be able to find a document containing “cycling” given the query “cycles”.

PyStemmer provides algorithms for several (mainly European) languages, by wrapping the libstemmer library from the Snowball project in a Python module.

It also provides access to the classic Porter stemming algorithm for English: although this has been superseded by an improved algorithm, the original algorithm may be of interest to information retrieval researchers wishing to reproduce results of earlier experiments.

There are three methods to install python-stemmer on Ubuntu 20.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
