Simon was a full-time PhD student in information retrieval at the Department of Computing, Imperial College London, in the Multimedia and Information Systems Group, supervised by Prof Stefan Rueger.

His research augmented the Geographic Information Retrieval process with information extracted from world knowledge. He approached this from three

directions: classifying world knowledge, disambiguating placenames and modelling users. Simon finished his PhD thesis...
