11. A method for monitoring a synchronous computer-mediated communication in which a text transcript is generated by at least two chat participants including a first chat participant and a second chat participant, the method comprising: setting up and maintaining a synchronous computer-mediated communication system between a plurality of chat participants; checking for potential frustration including checking the text transcript for use of a text-based signal in a list of text-based signals; and taking a responsive action based at least in part upon a potential cause of the potential frustration determined by performing a text analytics analysis on the text transcript; wherein: at least the checking step is performed by computer software running on computer hardware; the responsive action is designed to alleviate frustration of the second chat participant; the list of text-based signals is recorded in a user-specific dictionary being customizable by the first chat participant to include participant-specific text-based signals corresponding to the second chat participant; and the user-specific dictionary being customizable to indicate a participant-specific potential frustration precondition corresponding to the second chat participant during a chat session between the first chat participant and the second chat participant.
15. The method of claim 11 wherein: the list includes a global table and a local table; the global table includes a set of global text-based signals pre-determined by a group policy; and the local table includes a set of local text-based signals input by a first participant to supplement the set of global text-based signals and/or to exclude a global text-based signal from the set of global text-based signals.
