The recommendation engine has gained momentum over the last few years. With the proliferation of B2B Saas and various digital business models, demand for recommendation engines is surging rapidly. Collaborative filtering is one of the most popular algorithms used in recommendation engines. Some of the top-rated roles of collaborative filtering in a recommendation engine are -
- Predictive Analysis: With the help of collaborative filtering, a recommendation engine can make predictions regarding the interests of a user by collecting information on preferences from many other customers. A recommendation engine with collaborative filtering analyzes the preferences of a large group of people and finds a smaller subset of users with the same tastes as a particular user. For instance, while listening to music on Spotify, it may suggest the recommendations derived from other listeners with similar tastes in music.
- Enhancing Performance: Collaborative filtering offers a higher level of accuracy as it can smoothly analyze a large set of data. A recommendation engine with collaborative filtering is capable of improving the visibility of the content of your digital store by letting a large number of editors participate. For example, the ‘voted up’ stories by the community appear in the front page of Reddit. The more diverse and larger the community becomes, the more efficiently collaborative filtering can work in a recommendation engine.
- Providing Flexibility: A recommendation engine needs to be up-to-date and flexible enough to match up with the changing trends. Collaborative filtering serves this purpose. It captures the changing pattern of users’ interests over time and provides the most relevant recommendations to different users.
- Increasing Efficiency: Collaborative filtering makes a recommendation engine more apt for different users as it works in both user-based and content-based ways. A recommendation engine with user-based collaborative filtering works by analyzing the similarity between target users and other users. Content-based collaborative filtering measures the similarity between the content attributes rated or preferred by users and other items, this in turn increases the efficiency of a recommendation engine substantially.
