Text kmeans clustering with python

simple text clustering using kmeans algorithm

from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.cluster import KMeans

documents = ["the young french men crowned world champions",
             "Google Translate app is getting more intelligent everyday",
             "Facebook face recognition is driving me crazy",
             "who is going to win the Golden Ball title this year",
             "these camera apps are funny",
             "Croacian team made a brilliant world cup campaign reaching the final match",

## terms per cluster

terms = vectorizer.get_feature_names()

for i in range(true_k):
        print("Cluster %d:" % i, end='')

# Cluster 0: apps google funny camera extensions useful chrome driving face facebook
#
# Cluster 1: world cup young champions crowned french men qatar fifa played

## predicting the cluster of new docs

new_doc = ["how to install Chrome"]
Y = vectorizer.transform(new_doc)
prediction = clustering_model.predict(Y)
print(prediction)
# [0]

new_doc = ["UCL Final match is played in Madrid this year"]
Y = vectorizer.transform(new_doc)
prediction = clustering_model.predict(Y)
print(prediction)
# [1]
