Do translator trainees trust machine translation? An experiment on post-editing and revision

Despite the importance of trust in any work environment, this concept has rarely been investigated for MT. The present contribution aims at filling this gap by presenting a post-editing experiment carried out with translator trainees. An institutional academic text was translated from Italian into English. All participants worked on the same target text. Half of them were told that the text was a human translation needing revision, while the other half was told that it was an MT output to be postedited. Temporal and technical effort were measured based on words per second and HTER. Results were complemented with a manual analysis of a subset of the observations.
