Extracting Text Meaning using TF-IDF
Top N Sentences
In the concluding part of our text analysis project, we focus on identifying the most significant sentences within our text. The goal is to highlight the key elements of the text using the TF-ISF scores calculated for each sentence.
Selecting Key Sentences
- Choosing the Number of Sentences: We begin by determining
N, the number of sentences to highlight. ChoosingN = 5reflects our aim to concentrate on the five sentences that our analysis has identified as containing the most important information; - Pairing Sentences with Scores: We use Python's
zipfunction to associate each sentence in our listsentenceswith its respective TF-ISF score fromsentence_scores; - Sorting Sentences by Their Importance: After pairing sentences with their scores, we sort these pairs in descending order based on the scores;
- Identifying the Top Sentences: We then select the top
Nsentences from this ordered list. This step identifies the sentences that best represent the core content of the text, as determined by our analysis.
Task
- Pair each sentence with its corresponding TF-ISF score.
- Sort these pairs by their score in descending order.
- Extract the top N sentences with the highest TF-ISF scores.
Congratulations!
