1. A method, comprising:
providing, by a system including a processor, an overlay combined with a presentation of video content to each of a plurality of computing devices for presentation to illustrate commentaries temporally associated with portions of the video content, the plurality of computing devices including first and second computing devices; collecting, by the system, a plurality of commentaries from the plurality of computing devices, wherein a first presentation by the first computing device of the overlay combined with the video content is at a different time than a second presentation by the second computing device of the overlay combined with the video content, wherein a first commentary of the plurality of commentaries is obtained from the first computing device during the first presentation, and wherein a second commentary of the plurality of commentaries is obtained from the second computing device during the second presentation; detecting, by the system, in the plurality of commentaries a cluster of correlated commentaries having a temporal proximity to each other in relation to the video content; analyzing, by the system, the cluster of correlated commentaries based on key words; detecting, by the system, an educational aspect in the cluster of correlated commentaries, wherein the educational aspect corresponds to a behavioral pattern exhibiting a lack of understanding of a portion of the video content, and wherein the system determines the behavioral pattern according to regression analysis and the key words; transmitting, by the system, in response to the detecting of the educational aspect, a first message to more than one computing device of the plurality of computing devices from which commentaries of the cluster of correlated commentaries have been collected, wherein the first message provides notice of a potential for establishing an educational social network; establishing the educational social network responsive to receiving second messages from the more than one computing device of the plurality of computing devices from which the commentaries of the cluster of correlated commentaries have been collected, wherein the second messages indicate an interest in joining the educational social network; detecting, by the system, a decorrelation of commentaries collected from the plurality of computing devices, wherein the decorrelation indicates a lack of common interest between the plurality of computing devices in a portion of the educational social network; selectively terminating, by the system, the portion of the educational social network responsive to the detecting of the decorrelation. |
