in this we will learn how to get started with the natural language toolkit package prerequisite if we want to build applications with natural language processing then the change in context makes it most difficult the context factor influences how the machine understands particular sentence hencewe need to develop natural language applications by using machine learning approaches so that machine can also understand the way human can understand the context to build such applications we will use the python package called nltk (natural language toolkit packageimporting nltk we need to install nltk before using it it can be installed with the help of the following commandpip install nltk to build conda package for nltkuse the following commandconda install - anaconda nltk now after installing the nltk packagewe need to import it through the python command prompt we can import it by writing the following command on the python command promptimport nltk downloading nltk' data now after importing nltkwe need to download the required data it can be done with the help of the following command on the python command promptnltk download(
