Abstract: A method for real-time multiparty communications across a social network organized according to a fluid timeline is taught. In the method, a user accesses the social network. The user views a story posted by a first user and favorably reacted to by a second user. The user also likes the story, so the user favorably reacts to the posted story. Since a threshold number of users have favorably reacted to the posted story, a collective network group messaging feature is made available. The user accesses the feature participates in real time in a collective network group messaging session in a virtual room with at least one other user.

Abstract: A pattern matching engine interprets a query into a data structure resembling a finite state machine. Vertices in the query pattern are treated as states or stages, while edges connecting them are treated as state transitions or hops. To match the full pattern, the first stage is first matched by applying vertex filters, if any. If the vertex is eligible, its edges that satisfy the edge filters, if any, are followed to move to the neighbors that can potentially produce results, thus progressing to the next stage. This process is repeated; if all stages are matched, then the whole pattern has been matched successfully.

Abstract: In a data transmission terminal, a processor is configured to determine whether or not a change greater than or equal to a predetermined amount has occurred between values represented by multiple pieces of first sensor data stored on a memory when a state of communication has shifted from a normal state to a disconnected state.

The processor is configured to transmit the changed data to the external terminal by using a communicator. The processor is configured to transmit the unchanged data to the external terminal by using the communicator after the changed data are transmitted to the external terminal.
