Converting JSON to Lists

Lets make a function to parse the json and retrieve the top 4 cast and their names only

Now, lets vectorize the words and convert it into numbers.

We extract the top 5000 words from the tags

# Stemming words newdf.tags = newdf.tags.apply(stem) newdf.head()

Vectorization of Words

We vectorize the tags using the CountVectorizer library and then vectorize the given tagline adn convert into numpy array.

Most of the array will consist of 0s because not all the movie contains the 5000 words as its tags. It will only have selected words.

from sklearn.feature_extraction.text import CountVectorizer cv = CountVectorizer(max_features=5000 ,stop_words= 'english')

vectors = cv.fit_transform(newdf['tags']).toarray()

display(vectors.shape) display(vectors[0]) display(vectors[0].shape) display(len(cv.get_feature_names_out())) display(cv.get_feature_names())

/shared-libs/python3.7/py/lib/python3.7/site-packages/sklearn/utils/deprecation.py:87: FutureWarning: Function get_feature_names is deprecated; get_feature_names is deprecated in 1.0 and will be removed in 1.2. Please use get_feature_names_out instead.
  warnings.warn(msg, category=FutureWarning)

Calculating Similarity using cosine distance

Using cosine distances -- distance between two movies.

Cosine Distance: Distance between 2 vectors as an angle

Distance is inversely proportional to similarity -> high similarity, low distance

from sklearn.metrics.pairwise import cosine_similarity

similarity = cosine_similarity(vectors) display(similarity) display(similarity.shape)

Here, we have a matrix this represents an array or arrays, where each array is the distance between a given movie and all other movies. So the shape of the array is 4808x4808.

Lets see the distance of the movies from first movie.

# Retrieving the first movie newdf.iloc[0].title

similarity[0]

def recommend(movie): if newdf[newdf['title'] == movie].empty : print(f"{movie} not present in the database") else: movie_index = newdf[newdf['title'] == movie].index[0] distances = similarity[movie_index] movies_list = sorted(list(enumerate(distances)),reverse=True , key = lambda x : x[1])[1:6] print("Top picks for you: \n") for i in movies_list : display(movpre.iloc[i[0]][['title','release_date','runtime','crew']])

recommend('Avatar')
