Question

An algorithm that counts how many times a word appears in a document

Answer 1

Answer:

The Algorithm which counts how many words in a document appeared is

TF-IDF . This is known as term frequency and inverse document frequency.

Each word’s TF-IDF relevance is a normalized data format that also adds up to one.

The formula to find it is

w ₁ , ₂ = tf ₁ , ₂ $log*\frac{N}{df}$

Here

tf = Number of occurrences

N = number of documents

df = document containing words

By using this algorithm we can find the value of occurences of Word in the document
