Online Recommendation Engine

What Is An Online Recommendation Engine?

An online recommendation engine is a tool that suggests a variety of products and services to users, based on the insights drawn from their internet activity data. Some tools can also determine a user’s change in behavior to recommend a product that is in line with their newly found interest.

Recommendation Engine Examples

Here are some prevalent examples and how they work to influence consumer choices:

  • Netflix: Netflix tool offers up to 1,300 recommendation clusters that suggest movies and TV shows to a user, based on their moving ratings, browsing activity, or machine learning algorithms.
  • AWS: Amazon’s system uses machine learning algorithms to recommend development trends that can help business owners customize buyer experiences.
  • Musicovery: Musicovery tool offers real-time music recommendations based on a user’s playlist and an artist’s or track’s descriptive metadata, such as genre, mood, acoustic descriptor, location, era, or even mood.

Technology Stack For Online Recommendation Engine

Building a system from scratch requires various technologies that enable the tool to function as intended. The tech stack includes:

  • Artificial Intelligence (AI): AI technology helps recommenders make a rapid and near-accurate product or service suggestions to users, based on their visual needs and preferences.
  • Machine Learning: (ML): This algorithm segments customers based on data, preferences, and internet activity to help online recommenders target users with personalized suggestions.
  • Natural Language Processing (NLP): NLP is used in content-based recommendation engines to suggest products and services based on content synopses or Latent Semantic Analysis (LSA).

Types Of Recommendation Systems

There are three prevalent types of systems based on their suggestion techniques, including:

  • Content-based system: uses data insights from a specific user’s online activity and preference to recommend products or services that are in line with that user’s behavior or preferences.
  • Collaborative system: collects data and insights from multiple users to recommend products and services to another user. The information used is usually from customers with bordering tastes, preferences, or situations.
  • Knowledge-based system: information about a product or service, such as benefits or level of trust is fed into the system, which then recommends the same to online users, especially in complex domains where business-ready data is insufficient.

How Does It Work?

A typical eCommerce recommendation system works in four steps:

  • Data collection: Three types of data are collected, including explicit from ratings and reviews, implicit from user online activity, and psychographics.
  • Storage: data is stored in scalable resources that can accommodate the increasing amount of information gathered over time.
  • Analysis: Real-time, near-real-time, and batch analyses are done on data to gain insights.
  • Data filtration: Data is filtered using mathematical formulas to segment them into scripts that can easily be recognized by the engines.

Challenges Of Recommendation Engines

Although a product recommendation engine can be instrumental in enhancing customer experience, this system comes with various challenges as well, including:

  • Data sparsity: Some data sets are poorly formatted, making it challenging to segment critical and less-useful information from big data.
  • Scalability bottlenecks: Users generate data daily. At the same time, new products and services emerge nearly every day, overwhelming these systems.
  • Latent Association: information might be incorporated wrongly, resulting in mismatching or totally missing product labels.

Frequently Asked Questions About Online Recommendation Engine

How to measure recommendation engine's accuracy?

You can use a special metric known as Mean Average Precision at K (mAP@k) to measure the accuracy and performance of various tools. This metric evaluates the recommendation system in question from two perspectives:

  • Relevance of the predicted items;
  • Whether the most relevant predicted items are displayed at the top.

How recommendation engines are used?

A recommendation engine for eCommerce is used to improve product and personalized shopping experiences. 39% of businesses also reportedly use this system for predictive analytics, which helps them enhance operations.
