Abstract: A user of an instant messaging system may store names of other users of the instant messaging system on a participant list (which may be referred to as a “buddy list”), and the names may be categorized into one or more groups. Similarly, a user of a mobile device, such as a mobile telephone, may store contact information about people on the mobile device. Information describing the on-line presence of the user within the instant messaging system or the geographic location of a mobile device, such as a mobile telephone associated with the user, may be disseminated to users on the participant list or to people on the contact list based on notification information that is associated with groups of users or contacts.

A delegation model is used to control whether a user is permitted to make modifications to the notification information.

Abstract: A user maintains notification setting information having temporal periods capable of controlling, at least in part, the dissemination of information describing the on-line presence of the user within an instant messaging system or the geographic location of one or more mobile communications devices used by the user. The user may use multiple identities to communicate within the instant messaging system and/or with the mobile communications device or devices. The user can maintain sets of temporal periods for each of the multiple identities. Only one identity may be used at a specific time to communicate to a specific other identity, but the multiple identities of the user may be linked such that on-line presence and/or geographic location associated with one of the identities is disseminated based on the temporal periods set for one or more of the multiple identities.

Abstract: A system of computers on a wide area network that 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 that sends relevant information to the nodes is provided. 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 skill level of the participants, and language. Each of the network's nodes is represented as a vector of attributes and is searched efficiently and adaptively through a variety of multidimensional data structures and mechanisms. The system includes synchronization that can transform a participant's time attributes on the network and coordinate the activities and information for each participant.

Abstract: An instant messaging user may use a buddy list that includes a user-selected list of potential instant messaging recipients (“buddies”) to identify another instant messaging user with whom instant messages are to be exchanged. An instant messaging user also may use a buddy list for other purposes, such as to initiate playing of an on-line game or to invite participants to play an on-line game. Techniques are provided to transform a buddy list from one messaging-mode to another messaging-mode. The transformation may include, for example, substitution or re-ordering of groups of buddies, substitution of buddy icons associated with buddies, substitution of information displayed about buddies, and substitution of controls for directing operation of the buddy list.

An instant messaging user also may use a buddy list for other purposes, such as to initiate playing of an on-line game or to invite participants to play an on-line game. The buddy list may be used as an on-line game leaderboard that presents a list of players of the on-line game in ranked order.

Abstract: Organizing a participant list includes maintaining a participant list of users of an electronic communications system to be used by a first user of the electronic communications system. Communications strengths between the first user and each of the users included in the participant list are determined. The users included in the participant list are organized based on the corresponding communications strengths. Communications strengths may be determined for users included in a group within a participant list, and the users within the group may be organized within the group based on communications strength. An additional group in the participant list in which some or all of the users included in the participant list are organized based on communications strength may be provided.

Abstract: The system and method comprises enhancement of results for a search engine, wherein the results from the search engine are refined or reorganized, based upon information from an identified secondary source. The results obtained using a conventional search are compared against the identified secondary source, e.g. a ratings service, and are filtered and/or sorted appropriately. In some embodiments, identification of the secondary source, such as a ratings service comprising information which may supplement the subject of a search query, is based upon information entered by the user. In alternate embodiments, the secondary source is associated with a user, as part of general user-specified search parameters, wherein one or more parameters are consulted automatically for searches for appropriate subject matter.

Abstract: A system including an object-oriented programming language for building state-based applications with flow control, event loops, measures of similarity, and Boolean logic to dynamically control the interaction between members in a social network around content and, in particular, project-based activities, where the system collects and groups individuals who are members of a social network, projects or assignments and their content, and activities or processes within projects based on the attributes of the objects and runtime events to create a social context for learning or for other interaction.
