Cloud systems and methods for determining the probability that a second application is installed based on installation characteristics

An apparatus for providing a scored list of applications for use in recommending applications to a user, the apparatus comprising:

• a server configured to:
• communicate with the plurality of client computers;
• store a conditional probability table across a set of available applications provided by the server, wherein a first conditional probability in the conditional probability table is the probability that users of the server who have installed a first application in the set of available applications have also installed a second application in the set of available applications;
• receive a request to provide a conditional scored list of applications for a user;
• retrieve a set of user-installed applications for the user;
• calculate a total conditional probability for each application in the set of available applications, wherein the total conditional probability of an application in the set of available applications is a function of the conditional probabilities of the application obtained from the conditional probability table given each application in the set of user-installed applications;
• construct the conditional scored list of applications from the set of available applications, wherein a score of each application is its corresponding total conditional probability;
• and
• output the conditional scored list of application.
