PhD candidate (1.0 fte, 4 years) "Metaphor in Machine Translation''

Leiden University, Faculty of Humanities, Leiden University Centre for Linguistics (LUCL) and Leiden University Centre for Digital Humanities (LUCDH), is looking for a

PhD candidate (1.0 fte, 4 years) to work on

“Metaphor in Machine Translation: Professional Users’ Perspectives”, subproject of the NWO Vidi project “Metaphor in Machine Translation: Reactions, Responses, Repercussions [MTM]”.
The PhD candidate will be responsible for the Professional Users’ Perspectives work package, one of the subprojects within the NWO Vidi project “Metaphor in Machine Translation: Reactions, Responses, Repercussions [MTM project]”, funded for 2025-2029 by the Dutch Research Council (NWO), and directed by Dr. Aletta G. Dorst (Associate Professor of Translation and Human-Centred AI at Leiden University). The PhD candidate will also collaborate with the research team on the Machine Perspectives work package.

Metaphor in Machine Translation [MTM] project
One defining characteristic of human communication that remains problematic for Artificial Intelligence and Natural Language Processing is metaphors. Metaphors are pervasive in all forms of language use, from newspapers announcing ‘waves’ of migrants and ‘soaring’ prices to casual conversations in which we say we feel ‘down’ or ‘stuck’. They are notoriously hard to translate, even for humans, because of their linguistic and cultural embeddedness. And we do not currently know what happens to their forms, functions and effects when they are translated by machines lacking in world knowledge and cultural sensitivity. Yet people increasingly rely on machine translation websites and apps like Google Translate and SayHi for all kinds of written and spoken discourse, from tourists translating a menu or talking to the hotel receptionist to large multinationals and NGOs incorporating the technology into their standard workflow. While research shows considerable improvements in the quality of machine translation for many language combinations and text types, there is a growing concern that most machine-translated content is no longer checked or corrected by human beings. Even the best systems make mistakes and we do not know which errors lead to critical misunderstandings. The current project therefore undertakes the first comprehensive study of how machine translation may be reshaping our metaphors.

Through a combination of qualitative and quantitative methods, the team will investigate (i) how metaphors are machine-translated by state-of-the-art systems in both literature and journalism, where metaphors are often used creatively and persuasively to change our minds; (ii) how literary translators and journalists react and respond to such machine-translated metaphors when revising translations for professional use; and (iii) how machine-translated metaphors affect readers’ understanding and appreciation of literary and journalistic texts. In short, the project seeks to answer the question: Which metaphors are problematic in machine translation, when, why, and for whom?

PhD project: Professional Users’ Perspectives on Metaphor in Machine Translation
This work package answers the question “How do literary translators and journalists react and respond to machine-translated metaphors and what are the repercussions for professional practice?” Determining professional users’ familiarity with and opinions on using machine translation forms an integral part of this work package. The PhD candidate will be responsible for designing two user studies with professional users of Machine Translation, one with literary translators and one with journalists. The professional users will be invited to come to Leiden and translate / revise / write texts containing metaphors for their respective fields (literature and journalism) using different architectures (e.g. Google Translate > Neural Machine Translation and ChatGPT > Large Language Models). The process of the task will be recorded using a keystroke logger and screen recorder. Both the product and the process will be analysed by the PhD candidate to determine how the professional users react and respond to the metaphors. During individual follow-up interviews, the professional users will be invited to reflect on their decisions and the repercussions of using MT and AI to translate metaphors for professional practice and society more broadly.

The organisation
The Faculty of Humanities at Leiden University is a unique international centre for the advanced study of languages, cultures, arts, and societies worldwide, in their historical contexts from prehistory to the present. Our faculty is home to more than 6,000 students and 800 staff members. For more information see: https://www.universiteitleiden.nl/en/humanities.

Leiden University Centre for Linguistics (LUCL) is one of seven Institutes that falls under the Faculty of Humanities. With over 120 linguists working at the Institute, it is a rich research environment that prides itself on fostering scientific excellence. LUCL has a longstanding tradition in the study of the world’s languages and features unique linguistic expertise. Current theoretical insights are combined with modern experimental methods in its research profile area ‘Language Diversity in the World’. Researchers from our six umbrella research groups are experts in their respective fields but equally find innovative ways of collaborating with other fields and disciplines.

The Leiden University Centre for Digital Humanities (LUCDH) is an interdisciplinary centre that brings together students and faculty from across the Leiden community. Together, we are committed to the study of human cultures using computational approaches and to rethinking the role of the humanities in a digital age. The Leiden University Centre for Digital Humanities (LUCDH) promotes the informed and critical uses of digital technology and computational approaches in art, literature, history, area studies, linguistics, philosophy, religion, AI and other disciplines of the Humanities.

The Translation Lab hosts research and training activities in various aspects of translation, including audiovisual translation, machine translation and AI, translation process research and user’s reception. The Translation Lab is equipped with the latest computer-assisted translation tools, subtitling software, corpus processing tools, and AI/MT applications, freely available to all Leiden researchers and students. The Translation Lab runs the Leiden Translation talks and other events, inviting distinguished scholars to share their research on translation, localization, and technology.

Through research, teaching and outreach, we aim to deepen our understanding, both inside and outside academia, of the cognitive, historical, cultural, creative, and social aspects of human life. As an academic community, we strive to create an open and welcoming atmosphere, stimulating everyone to get involved and contribute, and connecting scholars from different fields and backgrounds.
