Problem:

My goal is to input 3 queries and find out which query is most similar to a set of 5 documents.

So far I have calculated the tf-idf of the documents doing the following:

from sklearn.feature_extraction.text import TfidfVectorizer

def get_term_frequency_inverse_data_frequency(documents):
    vectorizer = TfidfVectorizer()
    matrix = vectorizer.fit_transform(documents)
    return matrix

def get_tf_idf_query_similarity(documents, query):
    tfidf = get_term_frequency_inverse_data_frequency(documents)
The problem I am having is now that I have tf-idf of the documents what operations do I perform on the query so I can find the cosine similarity to the documents? The answer should be like a 3*5 matrix of the similarities.

A:

<code>
import numpy as np
import pandas as pd
from sklearn.feature_extraction.text import TfidfVectorizer
queries, documents = load_data()
assert type(queries) == list
assert type(documents) == list
def solve(queries, documents):
    tfidf = TfidfVectorizer()
    tfidf.fit_transform(documents)
    # return the solution in this function
    # cosine_similarities_of_queries = solve(queries, documents)
    ### BEGIN SOLUTION

library

Sklearn
