How recommendation system works: -

Recommendation system works on the aspects of Data collection and Data storage. What we search from the browser, recommendation search engine collects all the data, store in their own memory. Search engine recommended the things to user after comparing with the past searches so, the user get more effective and correct data with lesser time. After the storage, data recommendation system required the filtering the data to get the accurate result or to make the final recommendations.

Two types of filtering performed by recommendation system is content filtering and collaborative filtering.

If a person read an article from a book and another article is from second book is also similar to the first one then recommendation system suggests to the user to read that book because now recommender knows the taste of the user. This type of filtering called the content filtering.

In collaborative filtering some techniques are required to find the relevant data let's suppose user A watches the three movies and user B watches the two movies but that two movies are common with user A. At that time recommender suggest to user B to watch the third movie which user A had already watched. From two movies recommender gets to know about the taste of the user and they already collects the previous data.
