Process mining in health care

pmhcToday, I have given a lecture on process mining in the health care at the College of Biomedical Engineering & Instrumentation of the Zhejiang University at Hangzhou, China. I concentrated on the application of process mining in a clinical setting with different modalities of data. There are many challenges facing process mining with clinical data and there is a clear need for new algorithms that face this challenge.

Computational intelligence approaches to ontology alignment

OASToday, I have given the Information Systems Colloquium for the IS@IEIS and IS@W&I groups of the Eindhoven University of Technology. The presentation covered the application of multi-objective evolutionary methods to certain aspects of the ontology alignment problem in semantic information systems. In the discussion that followed, we have also explored the links of the problem to business process discovery and alignment.

Achieving semantic interoperability is an essential task for all distributed and open knowledge based systems. Currently, the technology recognized for fulfilling this complex task is represented by ontologies. However, the power of ontological representation is reduced by the semantic heterogeneity problem which affects two ontologies when they are characterized by terminological and conceptual discrepancies. The most solid solution to overcome this problem is to perform an ontology alignment process capable of leading two heterogeneous ontologies into a mutual agreement by detecting a set of correspondences between them. Performing this task is an essential step to allow the exchange of information between people, organizations and web applications using ontologies for representing their view of the world. In this presentation, we consider several computational intelligence approaches to ontology alignment. In particular, the use of memetic algorithms, evolutionary approaches and fuzzy set methods are discussed for tackling different aspects of the problem.

Impressive new container terminal rises in Maasvlakte 2

TAPMT_craneoday, I visited the new APM Terminal that is being built in Maasvlakte 2. This will be the first occupant of Maasvlakte 2. Many new logistics concepts are being developed and implemented at this terminal, which will help Rotterdam keep its leading position as the main harbor of Europe. The terminal can handle the largest container ships and can serve two such ships simultaneously!

The title of Anouk’s thesis was “Knowledge Translation and Maintenance in Health Care: identification of the requirements for tool support”. Her project was a collaboration with Catharina Hospital Eindhoven. More information about the thesis can be found here.

Portuguese hospitals prefer to be paperless

20121118-110945.jpgI visited two hospitals in the neighborhood of Lisbon. I understand that Hospital da Luz is the largest private hospital in Portugal. It resides in a large health complex consisting of an acute care hospital and a residential hospital. Hospital Beatriz Ángelo is a public-private partnership and is larger in size. Both hospitals have the strategy to be a “paperless” health centre. It was interesting to see the level of information systems integration they had achieved, which opens new avenues for operational excellence. I think many hospitals in the Netherlands have a lot to learn from their experience.
