A part of the EnRiMa system demonstrated in Brussels

The EnRiMa project partners gathered in Brussels 29-30 May to have the projects second review meeting. During the review meeting the prototype of the EnRiMa decisions support system was demonstrated for the reviewers. It was demonstrated how the system based on information about a building, such as existing heating equipment and inner volumes, could calculate the optimal way to manage the building. Furthermore it was demonstrated how the system could collect data from external systems, such as weather forecast providers and installed building management systems. A part of the team that demonstrated the system in Brussels was SysLab members Martin Henkel and Janis Stirna. The SysLab team also includes Wayne Westmoreland that together with Martin has worked on the implementation of the system. The EnRiMa project (Energy Efficiency and Risk Management in Public Buildings) is a European Commission funded collaboration between Stockholm University, University College London, International Institute for Applied Systems Analysis, Universidad Rey Juan Carlos, Minerva Consulting and Communication, SINTEF Group, Tecnalia, and Hidrocantábrico Energía.

Maria Skeppstedt and Aron Henriksson are currently visiting the Division of Biomedical Informatics (DBMI) at the University of California, San Diego, which is located in the San Diego Supercomputer Center (SDSC). The visit will last for a month and is one of several exchanges between the Natural Language Processing (NLP) group at DBMI and the Clinical Text Mining Group at DSV that have been made possible through the Interlock project.

Last week we were invited together with Wendy Chapman to give a talk at a PACE (Predictive Analytics Center of Excellence) seminar at SDSC. Wendy first talked about NLP in general, while Maria and I talked about our respective research on NLP in the clinical domain.

I was invited to give a talk in a seminar series held at the Language Technology Group (LTG), Department of Informatics, University of Oslo, on May 30th. The talk was entitled Shades of Certainty — Working with Swedish Medical Records and the Stockholm EPR Corpus and was about my recent dissertation work as well as ongoing and planned research within the Health Care Analytics and Modeling research group here at DSV.

It was a wonderful visit, thank you for inviting me, for interesting feedback and questions, and for a fantastic day and evening!

The Fourth International Symposium on Languages in Biology and Medicine (LBM 2011)

Health Informatics, Presentation, Publication, SYSLAB

Sumithra Velupillai attended The Fourth International Symposium on Languages in Biology and Medicine (LBM 2011) at the Nanyang Technological University in Singapore, December 14-15.

At LBM 2011, Sumithra presented the paper Automatic Classification of Factuality Levels – A Case Study on Swedish Diagnoses and the Impact of Local Context. In this paper, The Stockholm EPR Diagnosis-Factuality Corpus is described and used for building automatic classifiers. The classifier obtains promising results (best overall results are 0.699 average F-measure using all classes, 0.762 F-measure using merged classes), using simple local context features. Preceding context is more useful than posterior, although best results are obtained using a window size of 4. Lower levels of certainty are more problematic than higher levels, which was also the case for the human annotators in creating the corpus. A manual error analysis shows that conjunctions and other higher-level features are common sources of errors.

Comparing certainty level annotations in clinical NLP: a case study on Swedish and English within the Interlock project

Health Informatics, Presentation, SYSLAB

On the recent return from her research visit to the University of California, San Diego (UCSD), Sumithra Velupillai presented the results of a comparative study of certainty-level annotations in clinical NLP written in Swedish and English respectively. The research visit took place within the Interlock project – a collaboration between the IT for Health group at DSV and the School of Medicine’s Division of Biomedical Informatics at UCSD.

The aim of the research visit was to create a taxonomy for a characterization of the expression of (un)certainty in clinical text and to compare these expressions in Swedish and English emergency ward documentation . The overall goal of this research is to improve automatic information extraction from clinical narratives.
