About the Project

Lots of informative publicly available content is written in a language that may not be easy to understand by everyone. For example, the latest research on a disease, terms and conditions for using an app, documents in public administration, etc. Could we develop systems that automatically rewrite these types of documents so that a target reader can more easily understand them?

To accomplish the previous goal, we could work with several areas within Natural Language Processing. The main one would be Text Simplification, which aims to modify the content and structure of a text to make it easier to read and understand, while preserving its original meaning. Depending on the type of document and application, Text Summarization technology could also be included, aiming to generate a shorter version of the original text that contains the most relevant information. In addition, depending on the target reader, we could also consider a Machine Translation component, if the original texts are in one language (e.g. English) and the rewritten documents should be in another (e.g. Spanish).

Possible lines of research for a PhD that could be studied with the previous motivation are:

- Automatic Text Simplification for specific domains, such as medical, legal or public administration. Important progress has been done in simplifying news. However, tackling other domains incorporates new challenges, such as handling domain-specific terminology and reduced availably of resources.

- Readability-controlled Translation, combining Text Simplification with Machine Translation. Recent research has attempted to guide the “complexity” or readability of automatically translated texts. However, these works are limited in the type of documents explored, and progress has been measured only using automatic metrics, and not more reliable human judgments.

- Document-level Text Simplification, a more realistic use case for Simplification technology aiming to rewrite entire documents or webpages, instead of single sentences as is mostly done in current research. This line of work would potently involve Summarization technology as well.

Other projects could certainly be explored, depending on the specific research interests of the applicant. During their research, the PhD student would work on collecting appropriate datasets for training and evaluation, implementing machine learning models for the task, and designing suitable evaluation methodologies and metrics.
