How to fill out form classic tf-idf vector

How to fill out form classic tf-idf vector

1. Step 1: Gather the dataset that includes the text documents you want to calculate the classic tf-idf vectors for.
2. Step 2: Preprocess the text documents by removing stop words, punctuation, and converting all text to lowercase.
3. Step 3: Tokenize the text documents into individual words or terms.
4. Step 4: Calculate the term frequency (TF) for each term in the document. TF is the number of times a term appears in a document divided by the total number of terms in the document.
5. Step 5: Calculate the inverse document frequency (IDF) for each term. IDF is the logarithm of the total number of documents divided by the number of documents that contain the term.
6. Step 6: Multiply the TF and IDF values to get the classic tf-idf vector for each term in the document.

Who needs form classic tf-idf vector?
