Abstract: A system of computers on a wide area network establishes connections between nodes on the basis of their multidimensional similarity at a particular point in time in a certain setting, such as a social learning network, and sends information of value to those nodes. Dimensions in the definition of similarity include a plurality of attributes in time and community space. Examples of such dimensions and attributes may include a position in a learning community's project cycle, titles of readings and projects, the genre or subject matter under consideration, age, grade, or level of the participants, and language. The network's nodes are represented as a tensor field and are searched efficiently and adaptively through a variety of multidimensional data structures and mechanisms. The system includes a master clock that can transform a participant's time coordinates on the network, such as a social learning network, into Universal Time, and the synchronizer coordinates the position of each participant.

Abstract: Systems and methods for associating cohorts in a social networking environment are provided. At least two users of a social network can be associated in a cohort based at least in part on a determined relationship between the at least two users. This relationship can be different from relationships defined by the users. An analysis of one or more parameters of the at least two users in the cohort can be performed based at least in part on the cohort, wherein the one or more parameters are unrelated to association of the at least two users in the cohort. The parameters can be used to longitudinally measure parameters of the at least two users that may have been impacted by association in the cohort. At least a portion of the analysis can be communicated.

Abstract: A method and system to permit the creation of “parent” accounts within a school system's data transmission system which are associated with a parent's child or children who are students in the system. A parent account is capable of creation and access by various levels within the hierarchy of the system and is associated with one or more schools within the community being serviced by the entity providing the servers and community generation implementation engine.
