Priority assignment embodiments are discussed. In one embodiment, a system comprises a comparison component configured to make a first comparison of a first message of a message set against a mission with regard to a similarity of the first message to the mission to produce a first message similarity result and make a second comparison of a second message of the message set against the mission with regard to a similarity of the second message to the mission to produce a second message similarity result. The system also comprises a priority component configured to assign a transfer priority order among the first message and the second message through use of the first message similarity result and the second message similarity result, where the transfer priority order is based, at least in part, on the more similar a message is to the mission the higher priority given to the message.
