LPLP will develop cutting-edge AI techniques to extract and analyse legal rights and obligations related to property and land. Objectives include the development of Natural Language Processing algorithms to extract legal rights and obligations from Land Registry documents and the development of machine learning based legal risk models for property and land.
FloraGuard project : an UK ESRC funded project. FloraGuard will examine and map from a multidisciplinary perspective the criminal market in endangered plants affecting the UK. Quantitative evidence will come from a combination of surface (web forums, social media) and dark web (TOR forums) crawling of cyber-criminal activity; natural language & machine learning used to socio-economically map this activity at a community level.
Intel-Analysis DSTL : a UK DSTL funded project. Intel-Analysis DSTL uses argumentation schemes and evidential reasoning to support teams of analysts trying to evaluate conflicting hypotheses during real-time events. Evidence is obtained in real-time from a combination of human intelligence reports and information extraction from social media via natural language processing.

Quickstep project : a hybrid collaborative/content-based recommender system to recommend on-line research papers. Uses kNN multi-class paper classification and an ontology to enhance the profiling process. Two trials of the system were conducted, both lasting 1.5 months with 14 and 24 subjects. The results demonstrated the utility of using an ontological approach to user profiling and how applying domain knowledge can enhance profiling.
Foxtrot project : evolution of the Quickstep recommender system. Uses pearson-r correlation to recommend and kNN classification to profile user interests. An ontological approach is taken to represent user profiles. This allows users to visualize and edit profiles encouraging direct feedback on what the system thinks they are interested in. A year long trial is in progress with hundreds of staff, postgraduates and undergraduates from the university to evaluate the utility of this approach.
