MAchine Reading of patient recordS


MARS aims to automatically extract information from patient records written in English (in the form of benchmarking datasets) and in Dutch (using data from the university hospitals of KU Leuven) by designing, developing and evaluating advanced language technology for deep semantic processing of the texts which are often morpho-syntactically not well-formed. As a pilot use case, we investigate language technology for profiling and selecting diabetes patients in clinical trials.


LIIR coordinates the MARS project. The other MARS partners are the Quantitative Lexicology and Variational Linguistics group of KU Leuven (Prof. Ann Bertels and Dr. Kris Heylen), the Centre for IT & IP Law of KU Leuven (Dr. Els Kindt ), and UZ Leuven (Prof. Bart Van den Bosch and Prof. Erwin Bellon).


We have performed first experiments in recognizing temporal relations between events in the natural language texts of clinical records.
