Title:
Fuzzy compliance checking of healthcare process data on time-task matrices

Abstract:

Time-task matrices (TTM’s) are a common means to represent a standardized way of a healthcare process, a so-called care pathway. What we propose in this research, is checking to what extent the actual process execution data comply with the TTM in the perspectives of control-flow and data (timing, resources and possibly other data variables). Whereas the standard compliance checking techniques use rather crisp boundaries to measure the compliance, we propose to use fuzzy sets to allow a certain amount of flexibility. The method is tested through a retrospective case study at Maastricht University Medical Center+ on patients that underwent surgery for the treatment of aortic valve stenosis.

You are all welcome to Nick’s talk!

Title:

Measuring the influence of greenwashing practices on the public opinion – a twitter sentiment analysis

Abstract:

After the Deepwater Horizon Oil spill in 2010, BP has actively used greenwashing to try and improve its company image. Greenwashing is a common practice that provides the public with “false green information”. To see if these greenwashing practices are really improving the company’s image in the minds of the public a Twitter sentiment analysis is conducted. The sentiment analysis is based on a Naïve Bayes algorithm and tries to set out a sentiment trend over the time period 2009-2014, the sentiment trend is used to see if the public opinion improves after the identified greenwashing practices.
