As an ADAPT funded PhD researcher you will have access to a network of 85 global experts and over 250 staff as well as a wide multi-disciplinary ecosystem across 8 leading Irish universities. We can influence and inform your work, share our networks and collaborate with you to increase your impact, and accelerate your career opportunities. Specifically we offer:
One of the biggest challenges for Machine Translation (MT), both for developing MT systems as well as for evaluation, is the ability to handle discourse dependencies and the wider context of a document. Work on evaluation has shown that methodologies that rely on single isolated sentences often result in misevaluation because the evaluators cannot access all necessary information for proper decision about context related issues such as gender ambiguity, lexical ambiguity, gender and number agreement, etc. On the other hand, providing evaluators with context avoids such misevaluations. Furthermore, it has shown that many context-related issues vary across different domains. It is also shown that the context span necessary to solve these types of context-related issues varies, and is often longer than the 2-sentence context commonly used in the machine translation field.
On that account, developing new-generation human evaluation metrics to improve MTEval considering discourse-level features, context span and appropriate evaluation methodology is necessary.
Under the supervision of Dr Sheila Castilho and Dr Maja Popovic, the PhD student will aim to contribute to define which human-evaluation metrics will better handle translations performed at a document-level by analysing the suitability of state-of-the-art metrics in document-level evaluation set-ups, performed by different evaluators, for different goals.
This project is multidisciplinary in nature, and there will be potential for collaboration with experts in other areas of academia. The application of results from this project will be of interest to industry partners in any area of translation.
The PhD will take place in Dublin City University, School of Applied Language and Intercultural Studies.
