Abstract: A sequence of user actions is generated from a runtime trace of a client application that is analyzed against a set of detectors to infer a feature-level usage analytic. The feature-level usage analytic identifies a common trait among the various users that use a feature of the application and is used as a basis to reflect the user's experience with the feature. The feature-level usage analytic may be a level of the user's ability with the application or an application state that indicates an outcome of a group of users' usage with a particular feature. The feature-level usage analytic provides a developer with insight into the user's behavior when using the application.
