Summary  
This chapter explains how to calculate a TF-ISF score by multiplying a term’s frequency within a sentence (TF) by its inverse sentence frequency (ISF), capturing both its local relevance and global distinctiveness.  

General domain of usage  
Text analysis

The **TF-ISF score** for a word is derived by **multiplying its TF score by its ISF score** . This composite score encapsulates both the word's relevance within individual sentences and its distinctiveness within the broader textual landscape.

This project focuses on the design and implementation of a robust text summarizer, built using Python. By harnessing the capabilities of Python’s Natural Language Toolkit (NLTK), participants will gain hands-on experience in processing and analyzing textual data. The project covers a range of NLP techniques essential for text summarization. Participants will develop skills in parsing text and extracting meaningful content, learning how to filter essential information from large volumes of text.

We will be leveraging the powerful Natural Language Toolkit which is instrumental in the processing and analysis of textual data.
