11. A method, the method being implemented by a computer system including one or more processors and storage media storing machine-readable instructions, the method comprising: hosting, over a network, a panoramic content segment of digital content to client computing platforms on which users consume the panoramic content segment such that a field of view within a panorama of the panoramic content segment is selectable by a user during presentation of the panoramic content segment, the panoramic content segment having a beginning and an ending and having a segment duration from the beginning to the ending; receiving, over the network from the client computing platforms, user comment information conveying user comments for the panoramic content segment, the user comment information conveying a first user comment for the panoramic content segment including a time indication that identifies a point in time in the segment duration of the panoramic content segment and a location indication that identifies a viewing angle within the panorama of the panoramic content segment; determining a comment distribution for the panoramic content segment from the user comment information, the comment distribution representing three dimensions of data such that the user comments are plotted as a function of number of user comments, points in time across the segment duration, and viewing angles across the panorama of the panoramic content segment; identifying a comment cluster based on the comment distribution for the panoramic content segment, wherein the comment cluster is identified based on the user comment information including time indications that identify points in time that are within a first period of time within the segment duration and location indications that identify viewing angles that are within a first view range within the panorama, such that the comment cluster indicates an event within the panoramic content segment at a point in time within the first period of time and at a location within the first view range; in a recurring or ongoing matter, receiving view information over the network from a client computing platform associated with the user indicating a current field of view selected by the user during the presentation of the panoramic content segment, the view information including one or more visible ranges of viewing angles within the panorama for a window in time within the segment duration; determining, for the window of time within the segment duration, whether the first view range associated with the comment cluster identified is located within or outside the one or more visible ranges of viewing angles selected by the user; generating, responsive to a determination that the first view range associated with the comment cluster identified is located outside an individual one of the one or more visible ranges of viewing angles selected by the user during the window of time, alert information indicating the event within the panoramic content segment is located outside the current field of view selected by the user, effectuating transmission of the alert information over the network to a client computing platform associated with the user causing the client computing platform associated with the user to effectuate presentation of a notification based on the alert information.
11. A method, the method being implemented by a computer system including one or more processors and storage media storing machine-readable instructions, the method comprising: hosting, over a network, a panoramic content segment of digital content to client computing platforms on which users consume the panoramic content segment such that a field of view within a panorama of the panoramic content segment is selectable by a user during presentation of the panoramic content segment, the panoramic content segment having a beginning and an ending and having a segment duration from the beginning to the ending; receiving, over the network from the client computing platforms, user comment information conveying user comments for the panoramic content segment, the user comment information conveying a first user comment for the panoramic content segment including a time indication that identifies a point in time in the segment duration of the panoramic content segment and a location indication that identifies a viewing angle within the panorama of the panoramic content segment; determining a comment distribution for the panoramic content segment from the user comment information, the comment distribution representing three dimensions of data such that the user comments are plotted as a function of number of user comments, points in time across the segment duration, and viewing angles across the panorama of the panoramic content segment; identifying a comment cluster based on the comment distribution for the panoramic content segment, wherein the comment cluster is identified based on the user comment information including time indications that identify points in time that are within a first period of time within the segment duration and location indications that identify viewing angles that are within a first view range within the panorama, such that the comment cluster indicates an event within the panoramic content segment at a point in time within the first period of time and at a location within the first view range; in a recurring or ongoing matter, receiving view information over the network from a client computing platform associated with the user indicating a current field of view selected by the user during the presentation of the panoramic content segment, the view information including one or more visible ranges of viewing angles within the panorama for a window in time within the segment duration; determining, for the window of time within the segment duration, whether the first view range associated with the comment cluster identified is located within or outside the one or more visible ranges of viewing angles selected by the user; generating, responsive to a determination that the first view range associated with the comment cluster identified is located outside an individual one of the one or more visible ranges of viewing angles selected by the user during the window of time, alert information indicating the event within the panoramic content segment is located outside the current field of view selected by the user, effectuating transmission of the alert information over the network to a client computing platform associated with the user causing the client computing platform associated with the user to effectuate presentation of a notification based on the alert information. 14. The method of claim 11 , wherein determining the comment distribution for the panoramic content segment includes generating a graphical representation of the comment distribution determined.
