SemIIM2023 was a full-day workshop that took place on 7th November 2023 in Athens, Greece, colocated with the 22nd edition of the International Semantic Web Conference (ISWC2023). This workshop invited industrial as well as academic keynotes and papers, covering the challenges and solutions for addressing industrial information modelling, including methods and practices of representing concepts, relationships, constraints, rules and operations to specify data semantics for a chosen domain of interest. The workshop gathered the interested community and discussed the latest approaches for challenges both from the perspectives of academia and industry.
Information Modelling (IM) has been under the spotlight of both academia and industry for decades [1,2]. Important aspects of IM include methods and practices of representing concepts, relationships, constraints, rules and operations to specify data semantics for a chosen domain of interest. As a response to the IM challenge a number of modelling paradigms and languages arose and they range from ERM [3], UML [4], ORM [5] to OWL [6] and Knowledge Graphs [7] and come with a wide range of systems to support the life cycle of information models [8,9].
Despite the past success, existing approaches and systems for IM fail to cope with new challenges of overwhelming global industrial digitalization that requires advanced information models and aims at fully computerized, software-driven, automation of production processes and enterprise-wide integration of software components [10,11,12,13,14]. Such trend and the technological and industrial developments that come with it are an important part of Industry 4.0 and industrial Internet of Things [15]. It requires IM that, for example, allows to capture the functionality of and information flow between different assets in a plant, such as equipment and production processes. Moreover, it requires IM and models that are based on ISA and IEC standards and have a number of desirable properties, e.g., reusable, explainable, scalable, simulatable etc [16,17]. Such IM should allow for seamless data sharing and integration e.g., via data market places and across value chains [18,19]. These new challenges require new theory, methodology, best practice, systems and this should be developed, shared, and discussed by a wire range of stakeholders. Therefore, we initiated the 1st International Workshop on Semantic Industrial Information Modelling (SemIIM) to provide a venue for the community of industrial information modelling. This is the second edition of the workshop. The first edition [20] was held on 30th May 2022, in Hersonissos, Crete, Greece.
The 2nd International Workshop on Semantic Industrial Information Modelling (SemIIM) aims at gathering researchers and practitioners who work on addressing these challenges with the help of semantic technologies. We in particular invited IM experts who are excited and committed to push the frontiers of IM further and support modern industry in its current technological transformation. In our workshop we welcomed novel methods, systems, solutions, experience, and practice for semantic industrial information modelling.
The workshop included the sessions described in the following sections.
The Academic Keynote was given by Oscar Corcho at Universidad Politécnica de Madrid (Spain) on the topic: "On the Governance of all the Artefacts used in Knowledge Graph Creation and Maintenance Scenarios". Abstract: The creation and maintenance of knowledge graphs is commonly based on the generation and use of several types of artefacts, including ontologies, declarative mappings and different types of scripts and data processing pipelines, sample queries, APIs, etc. All of these artefacts need to be properly maintained so that knowledge graph creation and maintenance processes are sustainable over time, especially in those cases where the original data sources change frequently. It is not uncommon to have situations where ontologies are governed by an organisation or group of organisations, while mappings and data processing pipelines are handled by other organisations or individuals, using different sets of principles. This causes mismatches in the knowledge graphs that are generated, including the need to update all the associated artefacts (declarative mappings, sample queries, APIs, etc.) so as to keep up to date to changes in the ontologies, or in the underlying data sources. In this talk we will discuss several of the challenges associated to the maintenance of all of these artefacts in real-world knowledge graph scenarios, so as to provide some light into how we could set up a complete knowledge graph governance model that may be used across projects and initiatives.
The Industrial Keynote was given by Sten Grüner at ABB Corporate Research (Germany) on the topic "Asset Administration Shell -Industry 4.0 in theory and practice".
Abstract: Industry 4.0 is a more than 10-year-old vision of digitalised, adaptive and resilient industry based on converged IT/OT technologies breaching the gap between engineering and computer science. Over the year an understanding of gaps between different information domains across product and equipment lifecycle and supply chain emerged. Asset Administration Shell (AAS) concept was created to close this gap by implementing Digital Twin concepts for industrial applications. In this talk, I will give a brief introduction into AAS information model, implementations and present some selected pilots and demonstrators making use of this technology.
Eleven papers were submitted and accepted. The reviews were hosted at EasyChair. Each paper received at least three reviews from reviewers with different background and status. The following papers were accepted for publication and presented at the workshop:
• Automating Building Regulations Conformance Checking Using a Semantic Approach -Preliminary Results [21] • Semantic Association Rule Learning from Time Series Data and Knowledge Graphs [22] • Extending PLASMA for Industrial Semantic Modeling [23] • GraphGuard: Enhancing Data Quality in Knowledge Graph Pipelines [24] • The Design of the Diagrammatic and Semantic Models for Process Modelling Language for Digital Triplet [25
