On the Laravel News site there's a post showing an application of the IBM Watson Personality Insights service to discover trends and make predictions about future actions/preferences. They also show how to integrate it into your Laravel-based application thanks to this package.

One of the most important things as a business owner is being able to understand your customers’ needs and wants; such that you are able to offer them a personalized experience. This works great if you know your customers on a personal level, but what if you don’t?

[...] Sure you could send out a survey from your site, then collect a huge amount of data, then process, analyze and finally being able to tell what package fits which user. This seems tiresome and plus people’s tastes and preferences change over time and you would have to repeat this process over and over again each time you want to offer them something new. There has to be a better way, and there is.

The post talks about the services offered by IBM Watson and, more specifically, about Personality Insights. They cover some about what this service offers as related to web preferences and link to a demo application you can use to get more context about its handling. The post wraps up showing how to integrate the package into your application and working with requests/responses to the IBM Watson Personality Insights service.
