A Recommendation system can also be consider as target marketing tool for online business especially for E-commerce platform. This filtering system narrows down the selection options for user’s to make intelligent choice to purchase something.

How does Recommendation System Works?

Recommendation systems are based on AI algorithm which has the ability to learn and predict most preferred or liked product for user. A typical recommendation system is very intelligent that can work smartly in a dynamic environment. They generally used to past data to see which products are most preferred, purchased or liked by the customers.

Recommendations system are usually consists of four phase which are given below:

  1. Data Collection
  2. Data Storing
  3. Data Analysis
  4. Data Filtration

Data Collection

The first phase for building a recommendation engine is collecting the data. The dataset should be collected for every user who visits the website. However, the data that need to be collected can be in two forms i.e. Implicit and Explicit Data.

Implicit Data is collected from available data stream such as purchase/return history, cart events, search log, click through, page viewed etc. This data is collected for every user who visited the website.

Explicit Data is collected from signup forms, surveys, user’s comments, ratings etc.

Collecting behavior data is much easy because a website contains the log of user activities and this don’t any additional action. Since, every user has different preferences, liking, and disliking about the product therefor the data for every user can be different. Hence, this results in a large amount of information.

Data Storing

For smarter recommendation, you need to feed enormous data to recommendation engine. However, AI algorithm for recommendation system utilizes big data for effective prediction. To store such amount of information you need storage space. Different type of information collected in first phase helps in deciding which kind of storage you need to collect data. There are various ways for data storage such as SQL, NoSQL, Cloud SQL and many more. You need to choose a scalable storage depending upon amount of data you collected, ease of implementation, portability and managing the data.

Data Analysis

This is third phase for building recommendation engine. It is very important to analyses the data to find out the most similar user engagement data such as product, items etc. However, there are various analysis methods available for find out such type of data. One of the analysis
methods is batch analysis which implies vast data is needed to make right analysis. Another way for data analysis is Real-time system that use tool for processing analyzing the events.

This is the last and most important phase for recommendation system. Here data is got filtered out for making right recommendation. There are various algorithms used for data filtration or we can say recommending data as well. Some of which are explained below:

  • Content-Based : Content based Filtering is based on keywords used by user for describing preferences, items etc. Basically, this filters out the items or products that have similar characteristics to what user liked or viewed previously.
  • Collaborative : Collaborative Filtering recommends the items or products based on similar customers. Basically, it analyzes user’s activities, preferences, behavior and predicts what a user will like base on their similarities with other users.

It usually makes an assumption that the two customers who liked the same product previously, will like to view same ones in the future as well.

  • Hybrid System : As the name suggests, hybrid system are combination of both collaborative and content-based Filtration system. This algorithm follows both characteristics of products which user like or view and also recommend products which are liked by some other user based on their similarity. For instance, Amazon follows Hybrid Recommendation System for making right recommendation for people who visit their website
