Domain Experts Tailoring Interaction – Presentation at INTERACT 2011 in Lisbon

Posted on | September 6, 2011 | Comments Off on Domain Experts Tailoring Interaction – Presentation at INTERACT 2011 in Lisbon

The paper with the title “ Domain Experts Tailoring Interaction to Users – an Evaluation Study” will be presented at Interact 2011 coming Friday.


This paper presents ACKTUS, a modeling tool for developing knowledge-based systems for the health domain, and an evaluation study of the system. The main purpose of the evaluation was to investigate whether the functionality and interaction design of ACKTUS was sufficiently intuitive for the domain experts to contribute with knowledge and to model the interaction design of the three end users’ applications. Another purpose was to evaluate the applicability of the activity assessment protocol AAIMA for analysis. The study design was qualitative and formative, using observations and interviews with users to collect data. Three medical experts and two experts in occupational therapy participated, providing expertise in four different domains. The participants increased their understanding and skills during the evaluation period leading to improved knowledge-based applications. The AAIMA protocol proved to be useful and the results are fed into ongoing development work on developing the adaptive functionality of the ACKTUS systems.”

Evaluation study of DMSS-R presented at MIE 2011 in Oslo

Posted on | August 29, 2011 | Comments Off on Evaluation study of DMSS-R presented at MIE 2011 in Oslo

A paper with the title “Limitations in Physicians’ Knowledge when Assessing Dementia Diseases – an Evaluation Study of a Decision-Support System” was presented at the conference Medical Informatics in Europe 2011 in Oslo. The results showed that the system’s interpretation of available patient data has high compliance with the physician’s view on the patient case (84 %). The study also indicates which topics need more support in the form of personalized educational support. These results are fed into the ACKTUS-dementia application.


“There is a need to provide tools for the medical professional at the point of care in the assessment of a suspected dementia disease. Early diagnosis is important in order to provide appropriate care so that the disease does not cause unnecessary suffering for the patient and relatives. DMSS (Dementia Management and Support System) is a clinical decision-support system that provides support in the diagnosis of a dementia disease, which is in use in controlled clinical evaluation settings in four countries. This paper reports the results of evaluations done in use environments in these places during a period of two years. Data in 218 patient cases were collected by 21 physicians during their use of the system in clinical practice. In 50 of the cases the use of the system were also observed and the physicians were interviewed in 88 cases. The collected data and inferences made by the system were analyzed. To summarize the results, DMSS gave appropriate support considering the patient case, available information and the user’s skills and knowledge in the domain. However, the results also illuminated the need for extended and personalized support for the less skilled physician in the assessment of basic information about patients.”

ACKTUS at PAAMS 2011 and AAAL 2011

Posted on | April 11, 2011 | Comments Off on ACKTUS at PAAMS 2011 and AAAL 2011

The initial work on integrating argumentation-based inquiry dialogues between agents was presented at PAAMS 2011 (9th International Conference on Practical Applications of Agents and Multiagent Systems) in Salamanca the past week. The application of these dialogues was also put in an ambient assisted living context, which was presented at the workshop Agents in Ambient Assisted Living AAAL 2011, also in Salamanca.
