Speaker: Uzay Kaymak

Title: Leveraging linguistic modeling for clinical decision support

Abstract:
As electronic medical records become the norm for documenting medical history of patients, reuse of the data generated during the care process opens new ways of supporting clinical decisions. Advanced data analysis techniques, machine learning and data mining models that make secondary use of medical data are accepted more and more in clinical applications. Despite the advent of data-driven models, the practitioners find it important to have transparent models whose behavior can be understood well. In this respect, natural language is an effective means for communicating model behavior to the users. We argue that linguistic models based on fuzzy set theory form an excellent bridge between the data-driven modeling and the transparency required by the users in the clinical domain. In this presentation, we discuss data science challenges in the healthcare domain and consider several modeling approaches that use fuzzy set theory to develop models for supporting clinical decisions and improving the care process.

 

Micro to Macro in IS – at Which Level Should we Think ?

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

Title: Micro to Macro in IS – At Which Level Should we Think?

Abstract:
IBM already contemplated the issue of aggregation levels (admittedly from a slightly different angle) a little while ago (actually, before some of us were born …): https://www.youtube.com/watch?v=0fKBhvDjuy0. This presentation applies this line of thinking to IS design (taking the world of MPMS as an example context) and intends to make you consider where your considerations are, or rather where your considerations should be.

Colloquium IS (July 7, 2017) – Compliance verification of inter-organizational workflows

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

July 7, 2017, 12:30 – 13:30 (Paviljoen K.16).

Speaker: Pieter Kwantes

Title: Compliance verification of inter-organizational workflows

Abstract:
Inter-organizational workflows (IOW) are commonplace in industry. Often they are facilitated by an industry body for standardization of message formats, enabling electronic message exchanges between the participants of the IOW. The SWIFT organization, created in 1973 and responsible for maintaining message standards for the Financial services industry, is (to my knowledge) one of the first examples of such an industry body but there are many more (eg. HL7 for Healthcare, Rosetta in Electronics, EDSN for the Dutch energy market and so on). Making a design for an IOW and verifying its correctness is much more challenging than for an intra-organizational workflow and the stakes are higher. Ongoing research into this subject aims to find methods and tools to support this design and verification process. One question investigated in [1] is how to verify, using an automated procedure, that the design of a local workflow of an organization participating in an inter-organizational workflow is in compliance with the globally specified rules of that workflow. In this talk the results of [1] will be presented and future work will be discussed.
