Clinical Text Mining Group

We are a creative research group of computer scientists, engineers, computational linguists and physicians, that are performing research in both language technology and in health informatics, particulary we are trying to interpret clinical texts using both domain experts and machines. We are aiming to create the future tools for clinicians, tools at the cutting edge in computer science and computational linguisitics using Artificial Intelligence. Our research is based on data from the Stockholm EPR Corpus contained in Health Bank - Swedish Health Record Research Bank. Stockholm EPR Corpus encompasses more than two million patient records in Swedish from the years 2006-2014. We have developed a number of tools and created a set of lexical resources. For possible applications please read here (in Swedish).
We are involved in the following research projects:
