From the article: Within the HU University of Applied Sciences (HU) the department HU Services (HUS) has not got enough insight in their IT Service Management processes to align them to the new Information System that is implemented to support the service management function. The problem that rises from this is that it is not clear for the HU how the actual Incident Management process as facilitated by the application is actually executed. Subsequently it is not clear what adjustments have to be made to the process descriptions to have it resemble the process in the IT Service Management tool. To determine the actual process the HU wants to use Process Mining. Therefore the research question for this study is: ‘How is Process Mining applicable to determine the actual Incident Management process and align this to the existing process model descriptions?’ For this research a case study is performed using Process Mining to check if the actual process resembles like the predefined process. The findings show that it is not possible to mine the process within the scope of the predefined process. The event data are too limited in granularity. From this we conclude that adjustment of the granularity of the given process model to the granularity of the used event data or vice versa is important.

The aim of the present study was to investigate if the presence of anterior cruciate ligament (ACL) injury risk factors depicted in the laboratory would reflect at-risk patterns in football-specific field data. Twenty-four female footballers (14.9 ± 0.9 year) performed unanticipated cutting maneuvers in a laboratory setting and on the football pitch during football-specific exercises (F-EX) and games (F-GAME). Knee joint moments were collected in the laboratory and grouped using hierarchical agglomerative clustering. The clusters were used to investigate the kinematics collected on field through wearable sensors. Three clusters emerged: Cluster 1 presented the lowest knee moments; Cluster 2 presented high knee extension but low knee abduction and rotation moments; Cluster 3 presented the highest knee abduction, extension, and external rotation moments. In F-EX, greater knee abduction angles were found in Cluster 2 and 3 compared to Cluster 1 (p = 0.007). Cluster 2 showed the lowest knee and hip flexion angles (p < 0.013). Cluster 3 showed the greatest hip external rotation angles (p = 0.006). In F-GAME, Cluster 3 presented the greatest knee external rotation and lowest knee flexion angles (p = 0.003). Clinically relevant differences towards ACL injury identified in the laboratory reflected at-risk patterns only in part when cutting on the field: in the field, low-risk players exhibited similar kinematic patterns as the high-risk players. Therefore, in-lab injury risk screening may lack ecological validity.

This method paper presents a template solution for text mining of scientific literature using the R tm package. Literature to be analyzed can be collected manually or automatically using the code provided with this paper. Once the literature is collected, the three steps for conducting text mining can be performed as outlined below:• loading and cleaning of text from articles,• processing, statistical analysis, and clustering, and• presentation of results using generalized and tailor-made visualizations.The text mining steps can be applied to a single, multiple, or time series groups of documents.References are provided to three published peer reviewed articles that use the presented text mining methodology. The main advantages of our method are: (1) Its suitability for both research and educational purposes, (2) Compliance with the Findable Accessible Interoperable and Reproducible (FAIR) principles, and (3) code and example data are made available on GitHub under the open-source Apache V2 license.
In het RAAK-project, genaamd Groningen MAPS, is er veel data en kennis vergaard van waaruit antwoorden zijn geformuleerd op verschillende vragen rondom belasting en belastbaarheid van (top)sporters. Het onderzoek naar de factoren die invloed hebben op de prestaties en het blessurerisico van sporters heeft opgeleverd dat we nu meer inzicht hebben in de informatie die nodig is om gericht te zoeken naar verbanden tussen belasting en belastbaarheid. We hebben echter nog niet gekeken naar de data vanuit een datamining perspectief. Datamining is het gericht zoeken naar verbanden in een database met als doel het opstellen van profielen. Deze profielen kunnen nieuwe inzichten geven waardoor sporters van nog betere feedback voorzien kunnen worden. Het doel van het Top-up project is om kennis te ontwikkelen over het automatiseren van de verwerking en analyse van datastromen. Dit zal leiden tot een datasysteem wat automatisch analyses uitvoert achter de schermen. Met dit datasysteem kan de Groningen MAPS-data verder geanalyseerd worden (door middel van datamining) om nieuw inzicht te verkrijgen op het gebied van patronen in belasting en belastbaarheid van (top)sporters.
Kwaliteitscontroles in productieprocessen in de maakindustrie zijn vaak destructief en daarmee niet duurzaam. In dit project onderzoeken we hoe door toepassing van process mining op real time sensor data de kwaliteitscontrole al tijdens het productieproces kan worden uitgevoerd en potentiële problemen vroegtijdig ontdekt.Doel Het doel van het project is om op basis van realtime data de kwaliteit van het eindproduct van het productieproces te kunnen voorspellen en waar nodig het productieproces bij te sturen. Hiermee kan de industrie duurzamer werken. Resultaten Het project levert een AI software toolkit op met methoden en algoritmen voor toepassing in de productieprocessen in verschillende industrieën. Looptijd 15 januari 2021 - 15 november 2024 Aanpak Nieuwe process mining algoritmes worden ontwikkeld en getoetst in case studies bij verschillende industriële bedrijven. Op basis van de uitkomsten wordt een software toolkit ontwikkeld voor toepassing in de praktijk. Impact op onderwijs Studenten van instituut voor ICT gaan, samen met studenten van TU Eindhoven, cases studies uitvoeren bij verschillende industrieën. Cofinanciering Het project wordt gefinancierd door NWO (Nederlandse Organisatie voor Wetenschappelijk Onderzoek).
Production processes can be made ‘smarter’ by exploiting the data streams that are generated by the machines that are used in production. In particular these data streams can be mined to build a model of the production process as it was really executed – as opposed to how it was envisioned. This model can subsequently be analyzed and stress-tested to explore possible causes of production prob-lems and to analyze what-if scenarios, without disrupting the production process itself. It has been shown that such models can successfully be used to diagnose possible causes of production problems, including scrap products and machine defects. Ideally, they can even be used to model and analyze production processes that have not been implemented yet, based on data from existing production pro-cesses and techniques from artificial intelligence that can predict how the new process is likely to be-have in practice in terms of data that its machines generate. This is especially important in mass cus-tomization processes, where the process to create each product may be unique, and can only feasibly be tested using model- and data-driven techniques like the one proposed in this project. Against this background, the goal of this project is to develop a method and toolkit for mining, mod-elling and analyzing production processes, using the time series data that is generated by machines, to: (i) analyze the performance of an existing production process; (ii) diagnose causes of production prob-lems; and (iii) certify that a new – not yet implemented – production process leads to high-quality products. The method is developed by researching and combining techniques from the area of Artificial Intelli-gence with techniques from Operations Research. In particular, it uses: process mining to relate time series data to production processes; queueing networks to determine likely paths through the produc-tion processes and detect anomalies that may be the cause of production problems; and generative adversarial networks to generate likely future production scenarios and sample scenarios of production problems for diagnostic purposes. The techniques will be evaluated and adapted in implementations at the partners from industry, using a design science approach. In particular, implementations of the method are made for: explaining production problems; explaining machine defects; and certifying the correct operation of new production processes.
