Project description

Natural language processing (NLP) problems are often tackled in a supervised learning manner, relying on manually annotated data which are supposed to be gold and clean.

In reality, manually annotated data can be noisy, especially when there are ambiguities between categories that only well-trained experts are able to resolve.

However employing well-trained experts to annotate data is costly, and they are not always available. The question therefore is "How can we effectively train NLP models on noisy data?".

This project aims at tackling the problem by investigating several probabilistic techniques to model noise (as latent variables, for example) and integrating them into deep neural networks.

This project is especially important to low-resource language research, to several domains such as bio-medical, construction, and law, where human annotations are difficult to have.

Person specification

For information


Applicants will be required to evidence the following skills and qualifications.

  • You must be capable of performing at a very high level.

Applicants will be required to evidence the following skills and qualifications.

  • You will have good time management.
  • You will possess determination (which is often more important than qualifications) although you'll need a good amount of both.


Applicants will be required to address the following.

  • Comment on your transcript/predicted degree marks, outlining both strong and weak points.
  • Discuss your final year Undergraduate project work - and if appropriate your MSc project work.
  • How well does your previous study prepare you for undertaking Postgraduate Research?
