Resumen:   To keep up with the growing need for translation in today's globalised society, post-editing of machine translation is increasingly being used as an alternative to regular human translation. While presumably faster than human translation, it is still unsure whether the quality of a post-edited text is comparable to the quality of a human translation, especially for general text types. In addition, there is a lack of understanding of the post-editing process, the effort involved, and the attitude of translators towards it. This dissertation contains a comparative analysis of post-editing and human translation by students and professional translators for general text types from English into Dutch. We study process, product, and translators' attitude in detail. We first conducted two pretests with student translators to try possible experimental setups and to develop a translation quality assessment approach suitable for a fine-grained comparative analysis of machine-translated texts, post-edited texts, and human translations. For the main experiment, we examined students and professional translators, using a combination of keystroke logging tools, eye tracking, and surveys. We used both qualitative analyses and advanced statistical analyses (mixed effects models), allowing for a multifaceted analysis. For the process analysis, we looked at translation speed, cognitive processing by means of eye fixations, the usage of external resources and its impact on overall time. For the product analysis, we looked at overall quality, frequent error types, and the impact of using external resources on quality. The attitude analysis contained questions about perceived usefulness, perceived speed, perceived quality of machine translation and post-editing, and the translation method that was perceived as least tiring. One survey was conducted before the experiment, the other after, so we could detect changes in attitude after participation. In two more detailed analyses, we studied the impact of machine translation quality on various types of post-editing effort indicators, and on the post-editing of multi-word units. We found that post-editing is faster than human translation, and that both translation methods lead to products of comparable overall quality. The more detailed error analysis showed that post-editing leads to somewhat better results regarding adequacy, and human translation leads to better results regarding acceptability. The most common errors for both translation methods are meaning shifts, logical problems, and wrong collocations. Fixation data indicated that post-editing was cognitively less demanding than human translation, and that more attention was devoted to the target text than to the source text. [Source: Author]
