Abstract: Systems and methods are described herein for determining identifying features across messages communicated in a network. In examples, a system can be configured to receive first activity data associated with a first set of messages involving a first channel and extract feature vectors for each message. The system can receive second activity data associated with a second set of messages associated with a second channel, extract feature vectors for each message of the second set of messages, and compare a first feature vector from the first set of feature vectors with a second feature vector from the second set of feature vectors. A correlation value can be determined based on the comparison of the first feature vector with the second feature vector and the system can provide display data to the first device or the second device based on the correlation value satisfying a device or user correlation threshold.
