Content by Analyticsvidhya

Internet Search

When we speak of search, we think ‘Google’, but there are many other search engines like Yahoo, Bing, AOL, Duckduckgo etc. All of these search engines use data science algorithms to deliver the best results for our search query in a fraction of seconds. Considering that Google processes more than 20 petabytes of data every day. Had there been no data science, Google would not have been the ‘Google’ we know today.

Digital Advertisements (Targeted Advertising and re-targeting)

From display banners on websites to the digital billboards at airports- almost all of them are decided by using data science algorithms. This is why digital ads have been able to get a lot higher CTR than traditional advertisements. They can be targeted based on the user’s past behaviour.

Recommender Systems

EA Sports, Zynga, Sony, Nintendo, Activision-Blizzard have led the gaming experience to the next level using data science. Games are now designed using machine learning algorithms that improve/upgrade themselves as the player, moves up to a higher level. In motion gaming also, your opponent (computer) analyses your previous moves and accordingly shapes up its game.

Price Comparison Websites

Nowadays, price comparison websites can be found in almost every domain such as technology, hospitality, automobiles, durables, apparels etc.

Airline Route Planning

Airline Industry across the world is known to bear heavy losses. Except for a few airline service providers, companies are struggling to maintain their occupancy ratio and operating profits. With the high rise in air-fuel prices and the need to offer heavy discounts to customers has further made the situation worse. It wasn’t for long when airlines companies started using data science to identify the strategic areas of improvement. Now using data science, airline companies can:

  1. Predict flight delay
  2. Decide which class of airplanes to buy
  3. Whether to directly land at the destination, or take a halt in between (For example: A flight can have a direct route from New Delhi to New York. Alternatively, it can also choose to halt in any country.)
  4. Effectively drive customer loyalty programs

Southwest Airlines, Alaska Airlines are among the top companies who’ve embraced data science to bring changes in their way of working.

Fraud and Risk Detection

One of the first applications of data science originated from the Finance discipline. Companies were fed up with bad debts and losses every year. However, they had a lot of data that use to get collected during the initial paperwork while sanctioning loans. They decided to bring in data science practices in order to rescue them from losses. Over the years, banking companies learned to divide and conquer data via customer profiling, past expenditures and other essential variables to analyze the probabilities of risk and default. Moreover, it also helped them push their banking products based on customer’s purchasing power.

Delivery Logistics

Who says data science has limited applications? Logistic companies like DHL, FedEx, UPS, Kune+Nagel have used data science to improve their operational efficiency. Using data science, these companies have discovered the best routes to ship, the best suited time to deliver, the best mode of transport to choose thus leading to cost efficiency, and many more to mention. Furthermore, the data that these companies generate using the GPS installed, provides them with a lot of possibilities to explore using data science.


Apart from the applications mentioned above, data science is also used in Marketing, Finance, Human Resources, Health Care, Government Policies and every possible industry where data gets generated. Using data science, the marketing department of companies decide which products are best for Upselling and cross-selling, based on the behavioural data from customers. In addition, predicting the wallet share of a customer, which customer is likely to churn, which customer should be pitched for a high-value product and many other questions can be easily answered by data science. Finance (credit risk, fraud), Human Resources (which employees are most likely to leave, employees performance, decide employees bonus) and many other tasks are easily accomplished using data science in these disciplines.
