Finding the Most Important Words
Rank terms that define each document.
From Scores to Insight
A TF-IDF matrix is full of numbers, but the real payoff is reading it. The top-scoring words reveal what each document is truly about.
One Row Per Document
Each row of the matrix is one document, each column one word. To find key terms you scan a single row for its highest values.
