Research title: Identifying Latent Relationship Information in Documents for Efficient and Effective Sensitivity Review

Research Summary

I am a PhD student in the Information Retrieval Group, School of Computing Science. My Supervisors are Professor Iadh Ounis and Dr. Graham McDonald. My research is focused on technology-assisted sensitivity review that is performed to identify and protect sensitive information such as personal or confidential information in large collections of digital documents. The research specifically aims to augment information retrieval and natural language processing methods to develop a system that can assist the human sensitivity reviewers and review organisers with indicating sensitive information using latent relationships between documents.

Research Interests:

  • Sensitivity Classification
  • Technology Assisted Review
  • News Event Extraction
  • Knowledge Graphs
  • Graph Search
