Project: Discovering lever on safty in Netherlands based on social media data

The Information Systems group is often contacted by industrial organizations with assignments that could lead to student projects at various levels (master thesis project, bachelor completion project, etc.) Through this website we make these topics available to our students. In this post, we announce one such project, involving companies NIPPUR and AD.

Every year Algemeen Dagblad (AD) and its subsidiaries report in the newspaper and online on crime and perception of security of Dutch residents. This report is called ‘Crimewatch’ or ‘AD Misdaadmeter’. The articles are due somewhere February/March of each year.
The content is prepared by research journalists. They focus primarily on quantitative data. Data is received from the National Police.
AD would like to extend these reports by involving new sources to enhance to quality of the reports and by introducing new methods and techniques that allow to add new angles in reporting.

AD would like to extend the reports by datamining relevant text oriented data that can be found on the internet. To add the ‘sentiment’ of the people of the Netherlands about the topics mentioned.
Nowadays it is possible to collect social media data (as available on 100s of thousands websites e.g. Twitter, Facebook, Linkedin, blog posts etc etc). Next techniques exist to analyse these texts and determine positive or negative sentiment and corresponding confidence of prediction. In many messages additional information can be found to further analyse this data and determine certain topics of interest and geographical locations.
For AD it could be very interesting to determine what people are talking about when crime is concerned and how they feel about it. To investigate the relationship between actual crime and the perception of the people. If possible zooming in on specific topics and regions.

Student requirements:

  • dutch knowledge

Project Definitie Capability Assessment Model energiebedrijven

The Information Systems group is often contacted by industrial organizations with assignments that could lead to student projects at various levels (master thesis project, bachelor completion project, etc.) Through this website we make these topics available to our students. In this post, we announce one such project, involving company Avenade.

Background, Present situation:
Definitie Capability Assessment Model energiebedrijven

De wereld van energiebedrijven wordt steeds complexer en dynamischer. Door technologische trends en regulering vanuit de overheid worden steeds strengere eisen gesteld. Avanade heeft hard gewerkt om een oplossing voor deze markt neer te zetten op basis van Microsoft Dynamics AX* en MECOMS**. Als aanvulling op onze RapidResults implementatie methodologie en de hiervoor gebruikte HPUM proces modellen van Accenture, willen we graag een Capability Assessment Model (CAM) ontwikkelen voor onze MECOMS propositie.

Wij zijn op zoek naar een ambitieuze afstudeerder met bedrijfskundige achtergrond die het een uitdaging vindt om een onderzoek te doen naar de definitie van een verbeterd en op onze MECOMS propositie passend Capability Assessment Model

De opdracht bestaat uit:

  • het onderzoeken en evalueren van reeds bestaande Capability Assessment Modellen, zoals onder andere:
    • HPUM van Accenture;
    • SUOM van Ferranti.
  • het definiëren van het Capability Assessment Model voor MECOMS / RapidResults
    • inclusief een definitie van de implementatie vragen en processen/functionaliteit per bepaald assessment level;
  • een advies hoe dit verder door Avanade ingezet dient te worden bij klanten.

De opdracht kent een vaste component en verder is er ruimte voor eigen inbreng. Je kunt gebruikmaken van alle kennis die binnen Avanade aanwezig is en een cruciale rol spelen in deze ontwikkeling.

*Microsoft Dynamics AX is complete ERP-software van Microsoft voor middelgrote en grote organisaties. Het ondersteunt de primaire processen van klanten, zoals financieel, logistiek, inkoop, verkoop, CRM en service management. Door de ondersteuning van primaire processen, hebben implementaties hiervan vaak veel impact op de organisatie. Het change element wordt daardoor extra belangrijk. Onderscheidend aan Microsoft Dynamics AX is de eenvoudige aanpasbaarheid, schaalbaarheid en gebruiksvriendelijkheid. Daarnaast is het wereldwijd inzetbaar en gemakkelijk te integreren met andere oplossingen en technologie. Extra interessant aan Dynamics AX is dat de technologie kant wordt gecombineerd met de bedrijfskant. Vaak is Dynamics AX het hart van de complete platformoplossing en daarmee van alle andere Microsoft-technologieën die in de oplossing meegenomen worden.

**Avanade levert specifiek voor energie- en utility bedrijven MECOMS als oplossing bovenop Dynamics AX. Deze oplossing is de Microsoft standaard voor energieleveranciers, netbeheerders, energieproducenten en meer.

After this talk a drink will take place in the PVOC.

Title: BrainBridge Project: Results after 2 years

Abstract: In this talk, we survey the work that has been performed during the first two years of the ongoing BrainBridge project on Clinical Pathway Support.  The project consists of two PhD projects (by Hui Yan and Shan Nan). The talk will consist of an introduction (by Pieter Van Gorp), a part of compliance analysis (by Hui Yan) and a part on a dynamic checklist support system (by Shan Nan). The introduction will sketch the project background as well as BPMN 2.0 formalization work, which we have used as the basis for the compliance analysis support.  The second part will describe novel BPMN 2.0 based compliance analysis support and its application to two clinical scenario’s.  The third part will describe the limitations of paper-based as well as static electronic checklist support, then it will introduce TraceBook, a BPMN 2.0 based dynamic checklist support system that interfaces to the EMR and CDSS of the Catharina Hospital and which has interfaces for integrating other systems.  Finally, we will describe ongoing work, which primarily consists of maturing the aforementioned results and evaluating them in a clinical setting.

PhD defense of Rui de Almeida: Conditional Density Models Integrating Fuzzy and Probabilistic Representations of Uncertainty @June 26 Erasmus University Rotterdam

Erasmus School of Economics (ESE), Erasmus University Rotterdam – See More
On Thursday June 26 Rui de Almeida will defend his Ph.D. thesis entitled “Conditional Density Models Integrating Fuzzy and Probabilistic Representations of Uncertainty” @ Senate Hall, A-Building, Woudestein Campus 11.30-13.00 hrs.

Prom./coprom.: Uzay Kaymak / Prof.  João M. Sousa


Conditional density estimation is an important problem in a variety of areas such as system identification, machine learning, artificial intelligence, empirical economics, macroeconomic analysis, quantitative finance and risk management.

This work considers the general problem of conditional density estimation, i.e., estimating and predicting the density of a response variable as a function of covariates. The semi-parametric models proposed and developed in this work combine fuzzy and probabilistic representations of uncertainty, while making very few assumptions regarding the functional form of the response variable’s density or changes of the functional form across the space of covariates. These models possess sufficient generalization power to approximate a non-standard density and the ability to describe the underlying process using simple linguistic descriptors despite the complexity and possible non-linearity of this process.

These novel models are applied to real world quantitative finance and risk management problems by analyzing financial time-series data containing non-trivial statistical properties, such as fat tails, asymmetric distributions and changing variation over time.

Rethinking care processes

Methodological support is still severely limited for rethinking care processes, i.e. how to get from current process insights (as-is) to concrete improvement ideas (to-be).Due to the lack of this support, practitioners must rely substantially on their own experience and intuition to generate process improvement ideas during traditional brainstorming sessions.As a consequence, these sessions are at risk to lead to biased choices and neglecting interesting process alternatives.

In this presentation, I will discuss a new, systematic technique for rethinking care processes: the RePro (Rethinking of Processes) technique. Apart from that, I will discuss the promising preliminary results of a lab experiment in which the performance of the RePro technique is compared with the traditional brainstorming technique.

Open, networked science in machine learning.

Research in machine learning and data mining can be speeded up tremendously by moving empirical research results out of people’s heads and labs, onto the network and into tools that help us structure and alter the information. OpenML is a collaborative open science platform for machine learning. Through plugins for the major machine learning environments, OpenML allows researchers to automatically upload all their experiments and organize them online. OpenML automatically links these experiments to all related experiments, and adds meta-information about the used datasets and algorithms. As such, all research results are searchable, comparable and reusable in many different ways. Beyond the traditional publication of results in papers, OpenML offers a much more collaborative, dynamic and faster way of doing research.

After this talk a drink will take place in the PVOC.
