Methods and apparatus for determining, based on features of an electronic communication and schedule data of a user, reply content for inclusion in a reply by the user to the electronic communication

A method implemented by one or more processors, the method comprising:

• receiving an electronic communication sent to a user, wherein the electronic communication references an event, but is not a structured invitation for the event;
• determining availability of the user, to whom the electronic communication is sent, for the event referenced in the electronic communication;
• determining one or more message features of the electronic communication, the message features comprising a first message feature based on an n-gram in a body of the electronic communication;
• providing the message features and the availability of the user as input to a trained machine learning system;
• determining, based on output from the trained machine learning system, a likelihood that a reply to the electronic communication will include an invite and/or a poll;
• and
• when the likelihood satisfies a threshold, when the electronic communication is being viewed by the user, and before the user has provided any user interface input indicating a desire to reply to the electronic communication:
• providing, via a graphical user interface, an invite graphical indication of the invite and/or a poll graphical indication of the poll,
• receiving, via the graphical user interface, a selection of one of the invite graphical indication or the poll graphical indication;
• and
• in response to receiving the selection, automatically including corresponding one of the invite or the poll in a reply electronic communication that is a reply, by the user to whom the electronic communication is sent, to the electronic communication.

A system, comprising:

• an electronic communication stored in one or more non-transitory computer readable media, wherein the electronic communication is sent to a user and references an event, but is not a structured invitation for the event;
• at least one processor;
• memory coupled to the processor, wherein the memory stores instructions to be executed by the processor to perform steps comprising:
• determining availability of the user, to whom the electronic communication is sent, for the event referenced in the electronic communication;
• determining one or more message features of the electronic communication, the message features comprising a first message feature based on an n-gram in a body of the electronic communication;
• generating reply content and additional reply content based on the availability of the user to whom the electronic communication is sent and based on the one or more message features of the electronic communication;
• when the electronic communication is being viewed by the user and before the user has provided any user interface input indicating a desire to reply to the electronic communication:
• providing, via a graphical user interface, a graphical indication of the reply content,
• providing, via the graphical user interface and with the graphical indication of the reply content, an additional graphical indication of the additional reply content;
• receiving, via the graphical user interface, a selection of the graphical indication via a user interface input device;
• and
• in response to receiving the selection, automatically incorporating the reply content in a reply electronic communication that is a reply, by the user to whom the electronic communication is sent, to the electronic communication;
• wherein selection of the additional graphical indication via the user interface input device, in lieu of selection of the graphical indication, causes the additional reply content to be incorporated in the reply electronic communication.
