RESEARCH PROJECTS

Scholarly Document Information Extraction

Particular components of scholarly documents have different uses and can be extracted and analysed to help improve the speed and quality of scientific discovery. These include better understanding of the topics, problems, approaches, evaluation metrics, tools and datasets used in research. Extracting such data from natural language text allows computational analyses of works at a large scale.

TRL 6

Task Oriented Dialogue Systems

We now use voice- and text-enabled chatbots and dialogue systems often to accomplish tasks. We examine ways to improve such systems by incorporating everyday knowledge in the form of knowledge graphs and incorporating means to adapt trained systems to new domain application areas.

• Artificial Intelligence, Media

TRL 4

Recommendation Systems

Recommendations Systems curate our news feeds, and show products for us to buy, shows to watch and music to listen to. Our work examines the use of temporal and prerequisite constraints in improving recommendation systems quality in sparse data application areas, such as module and course recommendation.

TRL 5

Towards Controllable Generation for Scientific Document Summarization

This project enhances scientific document summarization by using scientific claims as constraints, improving summarization quality and user control. It integrates claim representation into seq2seq models like BART and T5, aiming for topic-based evaluation and plans to publish three works and deliver a practical toolkit.

TEACHING INNOVATIONS

Student Submission Integrity Diagnosis (SSID)

SSID is an instructor-centric source code plagiarism detection system (i.e., for programming assignments). It aims to streamline the checking process and helps instructors manage plagiarism detection workflows.
