Abstract: Systems and methods for communicating with secondary users of a transportation service are provided. A method can include obtaining a request for a transportation service including an aerial transport of a first user from a first user device associated with the first user. The method can include generating a first multi-modal transportation itinerary for facilitating the aerial transport for the first user. The method can include obtaining data indicative of a second user that is to travel with the first user for at least a portion of the first multi-modal transportation itinerary and determining a second multi-modal transportation itinerary for facilitating the aerial transport for the second user. The method can include communicating passenger itinerary data indicative of the second multi-modal transportation itinerary to a second user device associated with the second user.

Abstract: The disclosed embodiments provide a system that improves learner engagement in online discussions. During operation, the system selects an experience level for use in moderating answers to a question submitted to an online forum. Next, the system matches the experience level to a first subset of users in a set of potential respondents to the question. The system then improves an engagement of the first subset of users with the online forum by generating output that targets the first subset of users with the question, prior to displaying the question to a first remainder of the potential respondents that does not include the first subset of users.
