Price, Rating, And Popularity On The Blackberry App Store

Apps on the app store are strongly subjected to the market effects of popularity and tend to rely heavily on trends and peer pressure. While the market for Blackberry devices has greatly diminished to a niche population, the app store for their devices tends to have similar offerings as some of the bigger App Stores such as the Apple App Store and Google Play Store. Researchers at the College of Computer Science at University College London set out to investigate the popularity trends of apps on the blackberry app store using data mining techniques such as natural language processing to extract appĀ price, rating, advertised features, and other data about usage and downloads.

The researchers’ findings are quite relatable to what we have been learning in class. Namely, it was found that the number of features extracted in apps follows a power law which showed that the number of apps that share the same features is relatively small. Moreover, there is a strong correlation between price and the ratings of apps on the app store (the lower the price the higher the rating). While this paper fails to make a strong argument about popularity, inferences can be made that reflect the relationship we learned in class between price, popularity, and demand.
