Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

import gensimfrom gensim.utils import simple_preprocess
from gensim.corpora import Dictionary
import pprint

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

from gensim.summarization import keywords

Any command-line input or output is written as follows:

pip install gensim==3.8.3

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Without natural language processing (NLP) tools, the marketing team can only do basic operations with these text messages and data.”
