Modelling with AAS and RDF in Industry 4.0

Industry 4.0 has proposed the Asset Administration Shell (AAS) model for digital twins. This model should help to solve interoperability issues, a topic that is also addressed by the Semantic Web and its Resource Description Framework (RDF). AAS and RDF-based models have their own strengths. AAS models are easier to integrate with operational...

A hybrid-ai approach for competence assessment of automated driving functions

An increasing number of tasks is being taken over from the human driver as automated driving technology is developed. Accidents have been reported in situations where the automated driving technology was not able to function according to specifications. As data-driven Artificial Intelligence (AI) systems are becoming more ubiquitous in automated...

Towards a Comprehensive Methodology for Modelling Submodels in the Industry 4.0 Asset Administration Shell

The Industry 4.0 Asset Administration Shell is designed as a digital communication interface that exposes information of various aspects of an asset in Submodels, which are functional blocks. However, a methodology that identifies the set of Submodels required for a specific use case is lacking. This work therefore presents two results: 1) the...

On planning in a knowledge-hypergraph

Autonomous robots that operate in indoor, uncertain environments move around from one location to the next to fulfill a set of ordered task. To do so, they need a floor plan of the building to plan their route. In case the building is unfamiliar to a robot it can employ online mapping techniques, though these techniques are resource intensive...

Towards data-driven ontologies: A filtering approach using keywords and natural language constructs

Creating ontologies is an expensive task. Our vision is that we can automatically generate ontologies based on a set of relevant documents to create a kick-start in ontology creating sessions. In this paper, we focus on enhancing two often used methods, OpenIE and cooccurrences. We evaluate the methods on two document sets, one about pizza and...

Driver readiness model for regulating the transfer from automation to human control

In the collaborative driving scenario of truck platooning, the first car is driven by its chauffeur and the next cars follow automatically via a so-called 'virtual tow-bar'. The chauffeurs of the following cars do not drive 'in the towbar mode', but need to be able to take back control in foreseen and unforeseen conditions. It is crucial that...

The federated ontology of the pal project interfacing ontologies and integrating time-dependent data

This paper describes ongoing work carried out in the European project PAL which will support childre in their diabetes self-management as well as assist health professionals and parents involved in the diabete regimen of the child. Here, we will focus on the construction of the PAL ontology which has been assemble from several independently...

An ontology for automated scenario-based training

An intelligent system for automated scenario-based training (SBT) needs knowledge about the training domain, events taking place in the simulated environment, the behaviour of the participating characters, and teaching strategies for effective learning. This knowledge base should be theoretically sound and should represent the information in a...

Neural-symbolic cognitive agents: Architecture and theory

In real-world applications, the effective integration of learning and reasoning in a cognitive agent model is a difficult task. However, such integration may lead to a better understanding, use and construction of more realistic models. Unfortunately, existing models are either oversimplified or require much processing time, which is unsuitable...
