Implementations of the present disclosure are directed to a method, a system, and an article for translating chat messages. An example method can include: receiving an electronic text message from a client device of a user; normalizing the electronic text message to generate a normalized text message; tagging at least one phrase in the normalized text message with a marker to generate a tagged text message, the marker indicating that the at least one phrase will be translated using a rule-based system; translating the tagged text message using the rule-based system and a machine translation system to generate an initial translation; and post-processing the initial translation to generate a final translation.
