Generating personalized smart responses

A messaging system comprising:

• one or more computer processors;
• and
• one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the messaging system to perform operations comprising:
• receiving, from a first client device, a first message transmitted as part of a communication session between a first user associated with the first client device and a second user associated with a second client device, the first user and the second user being members of an online service that facilitates the communication session, the second user being an intended recipient of the first message and the first user being a sender of the first message;
• determining, using the first message as input in a statistical model, a set of candidate responses for the second user to reply to the first message in a second message in which the second user is the sender of the second message and the first user is the intended recipient of the second message, the statistical model having been generated based on historical message data transmitted as part of previous communication sessions between a plurality of members of the online service, and the set of candidate responses being a subset of a set of available candidate responses;
• filtering the set of candidate responses based on a personalized vocabulary for the second user, yielding a set of personalized candidate responses, the personalized vocabulary for the second user having been determined based on member profile data associated with the second user, wherein filtering the set of candidate responses based on a personalized vocabulary for the second user comprises:
• determining a demographic category of the first user;
• and
• filtering the set of candidate responses based on a subset of the personalized vocabulary for the second user that includes keywords commonly used by the second user when communicating with users in the demographic category of the first user;
• determining, based on a set of personalized candidate selection rules, a subset of the set of personalized candidate responses, yielding a set of recommended responses to the first message;
• and
• causing the set of recommended responses to be presented in a user interface on a display of the second client device, the set of recommended responses presented along with the first message, the user interface configured to allow for selection of the set of recommended responses to transmit the second message to the first user.
