In my research, I connect the modelling of behaviour (eg. from Artificial Intelligence, Cognitive Systems, Business Process Modelling, and dynamical systems) with web technologies for semantic knowledge representation (Knowledge Graphs, RDF, OWL) and system interaction (HTTP). Authorisation and authentication in this context requires identities, e.g. decentralised (DID) or self-sovereign (SSI). With this basis at hand, we can specify web agents, also called intelligent clients, which can automate things for you on the web, the Internet of Things, or in Industry 4.0. In the area of analytics, I investigate methods to analyse time series of semantically described data, e.g. the evolution of data on the Linked Data web.
Currently, I coordinate the COST Action 19134, a European network on the topic of Distributed Knowledge Graphs, I led the AI part of KIGLIS, a BMBF-funded project on AI and the optical communication networks in a Smart City, I lead the KIT part of BMBF-funded project MANDAT about using web technologies for data ecosystems with data fiduciaries, I help in the BMBF-funded DigiBatMat to digitise battery material sciences using semantic technologies, I serve as program chair at KIT in SeReCo, a german-french doctoral college.
In the near future, the DFG-funded AI research group 5339 starts at KIT and Fraunhofer about the fast maturisation of immature manufacturing processes using AI methods, where I am among the PIs.
Recently, we completed TraPS, a project on decentralised Knowledge Graphs and the Blockchain for Supply Chains, and DataScore about incentives for good research data management.
In terms of community service, I organise ATAC, a challenge on agents and Linked Data for the International Semantic Web Conference (ISWC 2021) and I serve on the organising committee for the 2020 and 2021 edition of the SEMANTiCS conference.
Find an overview on my publications here, on Google Scholar, Semantic Scholar, ORCID, and on DBLP.
Find some code I wrote on Github, where I publish Read-Write Linked Data (REST + Linked Data) intefaces to systems, IoT sensors and actuators, and services, besides code to harvest and process Linked Data.
