Content Based Recommender System recommends movies similar to the movie user likes and analyses the sentiments on the reviews given by the user for that movie.
The details of the movies(title, genre, runtime, rating, poster, etc) are fetched using an API by TMDB, https://www.themoviedb.org/documentation/api, and using the IMDB id of the movie in the API, I did web scraping to get the reviews given by the user in the IMDB site using beautifulsoup4 and performed sentiment analysis on those reviews.

I've developed a similar application called "The Movie Cinema" which supports all language movies. But the only thing that differs from this application is that I've used the TMDB's recommendation engine in "The Movie Cinema". The recommendation part developed by me in this application doesn't support for multi-language movies as it consumes 200% of RAM (even after deploying it to Heroku) for generating Count Vectorizer matrix for all the 700,000+ movies in the TMDB.

If you can't find the movie you're searching for through auto-suggestions while typing, there's no need to worry. Simply type the name of the movie and press "enter". Even if you make some typos, it should still work fine.

How does it decide which item is most similar to the item user likes? Here come the similarity scores.
It is a numerical value ranges between zero to one which helps to determine how much two items are similar to each other on a scale of zero to one. This similarity score is obtained measuring the similarity between the text details of both of the items. So, similarity score is the measure of similarity between given text details of two items. This can be done by cosine-similarity.
Cosine similarity is a metric used to measure how similar the documents are irrespective of their size. Mathematically, it measures the cosine of the angle between two vectors projected in a multi-dimensional space. The cosine similarity is advantageous because even if the two similar documents are far apart by the Euclidean distance (due to the size of the document), chances are they may still be oriented closer together. The smaller the angle, higher the cosine similarity.
