11. A system including: at least one processor; and memory including instructions which, when executed by the at least one processor, cause the at least one processor to: receive original content associated with a first language from a first client machine; translate the original content to machine-translated content associated with a second language; determine individual confidence scores for a plurality of expressions of the machine-translated content, each expression comprising at least one of a word or a phrase; determine individual probability scores for the plurality of expressions; determine individual combined scores for the plurality of expressions from the individual confidence scores and the individual probability scores; determine, based on the individual combined scores for the plurality of expressions, a part of the machine-translated content fails to satisfy a quality threshold; transmit a part of the original content corresponding to the part of the machine-translated content failing to satisfy the quality threshold to a second client machine; and receive a translation of at least the part of the original content from the second client machine.

The system of claim 11 , wherein the instructions when executed further cause the at least one processor to: receive second original content associated with the first language; translate the second original content to second machine-translated content associated with the second language; determine that the second machine-translated content satisfies the quality threshold; and publish the second machine-translate content without further translation by any human translator.
