De meest gebruikte opbouw in business intelligence, predictive analitics en analytics modellen is de moeilijkheidsgraad: 1) descriptive, 2) diagnostic, 3) predictive en 4) prescriptive. Deze schaal vertelt iets over de volwassenheid van het gebruik van data door de organisatie. Een model dat niet op zichzelf staat en een achterliggende methode kent is de data driehoek van EDM (Figuur 1), welke in dit artikel zal worden toegelicht.

Abstract Despite the numerous business benefits of data science, the number of data science models in production is limited. Data science model deployment presents many challenges and many organisations have little model deployment knowledge. This research studied five model deployments in a Dutch government organisation. The study revealed that as a result of model deployment a data science subprocess is added into the target business process, the model itself can be adapted, model maintenance is incorporated in the model development process and a feedback loop is established between the target business process and the model development process. These model deployment effects and the related deployment challenges are different in strategic and operational target business processes. Based on these findings, guidelines are formulated which can form a basis for future principles how to successfully deploy data science models. Organisations can use these guidelines as suggestions to solve their own model deployment challenges.

Over the past few years, there has been an explosion of data science as a profession and an academic field. The increasing impact and societal relevance of data science is accompanied by important questions that reflect this development: how can data science become more responsible and accountable while also responding to key challenges such as bias, fairness, and transparency in a rigorous and systematic manner? This Patterns special collection has brought together research and perspective from academia, the public and the private sector, showcasing original research articles and perspectives pertaining to responsible and accountable data science.

In the rapidly evolving field of Machine Learning , selecting the most appropriate model for a given dataset is crucial. Understanding the characteristics of a dataset can significantly influence the outcomes of predictive modeling efforts, making the study of the properties of the dataset an essential component of data science. This study investigates the possibilities of using simulated human data for personalized applications, specifically for testing clustering approaches. In particular, the study focuses on the relationship between dataset characteristics and the selection of the optimal classification model for clusters of datasets. The results of this study provide critical insights for researchers and practitioners in machine learning, emphasizing the importance of dataset characteristics and variability in building and selecting robust models for diverse data conditions. The use of human simulation data provide valuable insights but requires further refinement to capture the full variability of real-world conditions.

In this study, a data feedback program to improve teachers’ science and technology (S&T) teaching skills was designed and tested. The aim was to understand whether and how the four design principles underlying this program stimulated the intended teacher support. We examined how teachers in different phases of their career applied and experienced the employed design principles’ key aspects. Eight in-service teachers and eight pre-service teachers attended the data feedback program and kept a logbook in the meantime. Group interviews were held afterwards. Findings show that applying the four employed design principles’ key aspects did support and stimulate in- and pre-service teachers in carrying out data feedback for improving their S&T teaching. However, some key aspects were not applied and/or experienced as intended by all attending teachers. The findings provide possible implications for the development and implementation of professional development programs to support in - and pre-service teachers’ S&T teaching using data feedback.

Recent years have seen a massive growth in ethical and legal frameworks to govern data science practices. Yet one of the core questions associated with ethical and legal frameworks is the extent to which they are implemented in practice. A particularly interesting case in this context comes to public officials, for whom higher standards typically exist. We are thus trying to understand how ethical and legal frameworks influence the everyday practices on data and algorithms of public sector data professionals. The following paper looks at two cases: public sector data professionals (1) at municipalities in the Netherlands and (2) at the Netherlands Police. We compare these two cases based on an analytical research framework we develop in this article to help understanding of everyday professional practices. We conclude that there is a wide gap between legal and ethical governance rules and the everyday practices.

Nederland zet koers richting een open vorm van wetenschapsbeoefening, getuige onder andere de lancering van het Nationaal Plan Open Science (NPOS) afgelopen februari en het nieuwe regeerakkoord dat stelt dat open access en open science de norm worden in wetenschappelijk onderzoek. Open science heeft als doel om wetenschappelijke kennis op transparante wijze en voor een breed publiek te publiceren. Dat vergt een herijking van onderzoek doen, samenwerking tussen onderzoekers en de wijze waarop kennis wordt gedeeld en de wetenschap wordt georganiseerd. Informatieprofessionals kunnen hierbij een rol van betekenis spelen, zoals blijkt uit cases van de Universiteit Utrecht, Hogeschool van Arnhem en Nijmegen en KNMI. Maar eerst een korte toelichting op open science en het NPOS. http://www.informatieprofessional.nl

This final installment in our e-learning series offers a comprehensive look at the current impact and future potential of data science across industries. Using real-world examples like medical image analysis and operational efficiencies at Rotterdam The Hague Airport, we showcase data science’s transformative capabilities. The video also introduces the promise of Large Language Models (LLMs) such as Chat GPT and the simplification brought by Automated Machine Learning (AutoML). Emphasizing the blend of technology and human insight, we explore the evolving landscape of AI and data science for businesses.

Dit project poogt een bijdrage te leveren aan het versterken van “de kennisketen van de gastvrijheidseconomie” middels de volgende projectdoelstellingen: • SWOT-analyse van huidige situatie, vanuit verschillende stakeholderperspectieven: kijkend vanuit de ontwikkelopgaves die men ziet, aan welke data over de customer journey is behoefte (inventarisatie)? Wat zijn de bijbehorende sterktes, zwaktes, kansen en bedreigingen (analyse)? • Versterken van de kennisketen via: hoe kunnen we kennisketen versterken met nieuwe technieken en door slim organiseren? • Een overzicht van strategische opties: welke strategische opties zijn er om 1.) sterktes te benutten om kansen te pakken en bedreigingen af te wenden en 2.) zwaktes op te lossen door kansen te pakken en gevaren te voorkomen die met bedreigingen meekomen • Input leveren voor 2.0 versie van het manifest van Gastvrij Overijssel en de beoogde oprichting van een “Data Hub” (waarvoor nog geen officiële werktitel) In de opvolgende hoofdstukken en paragrafen gaan we in op de aanpak (hoofdstuk 2) en de uitkomsten (hoofdstuk 3).
