Abstract: In one embodiment, a device obtains quality of experience labels for an online application accessible via a network. The device also obtains telemetry data from the network that is associated with quality of experience labels. The device makes, based on the quality of experience labels and telemetry data, a determination as to whether the online application is similar to a second online application for which a prediction model is already available. The device trains, based on the determination, a prediction model for the online application to predict a quality of experience metric for the online application.

Abstract: In one embodiment, a data sharing platform uses data associated with a data owner to share data via a plurality of sharing services, each sharing service in the plurality of sharing services providing a different type of data. The data sharing platform tracks access to each of the plurality of sharing services. The data sharing platform computes, based in part on the access to each of the plurality of sharing services, an importance metric for the data associated with the data owner. The data sharing platform provides an indication of the importance metric for display to the data owner.
