Lifelog is the product that pushed Sony Mobile to become a data-driven company. In this talk we will show how we use large scale analytics on Spark to generate insights to Lifelog users about themselves and the population, through some specific examples. We also use analytics of usage data to understand our users and to improve our applications with data-driven design. Furthermore we have developed a user lifecycle model that allows us to formulate and test hypotheses for actions toward increased user engagement and retention. We will present the model and discuss some results.
Example applications will also be demonstrated, showing how third party application developers can access and integrate Lifelog data and insights into their applications with permissions from the user, through the open Lifelog API.
