Abstract: In a device including a processor and a memory, the memory includes executable instructions that, when executed by the processor, cause the processor to control the device to perform functions of receiving an access control setting for granting access to an access-controlled resource and a dynamic tag characterizing a member group subject to the access control setting; accessing a data source storing member data including an attribute associated with each member, the attribute including a parameter related to a time or time period. The dynamic tag is mapped to the member data based on (1) the parameter of the attribute and (2) a time or time period associated with the dynamic tag, to identify mapped members forming the member group, wherein the mapped members identified based on a same dynamic tag vary depending on the time or time period associated with the dynamic tag, to identify the member group.

Abstract: In a communication device including a processor and a computer-readable medium, the computer-readable medium includes instructions for performing receiving a text input composing a message, the text input including a word characterizing a recipient group; transmitting the text input to a server; receiving, from the server, feedback data indicating that the recipient group for the message has been identified; in response to receiving the feedback data, providing an indication that the recipient group for the message has been identified; receiving a user input requesting to send the message to the identified recipient group; and in response to receiving the user input, transmitting, to the server, a request to send the message to the identified recipient group.

Abstract: In a device including a processor and a memory in communication with the processor is disclosed. The memory includes executable instructions that, when executed by the processor, cause the processor to control the device to perform functions of receiving, via a communication network from a device, a message and a dynamic tag associated with the message, the dynamic tag characterizing a recipient group for the message; determining that the dynamic tag is relevant to a data set including an attribute of a plurality of members corresponding to the dynamic tag; based on the dynamic tag and the attribute, identifying, from the plurality of members, a member group relevant to the dynamic tag; and sending, via the communication network, the message to a device group associated with the member group.
