Recently, semantic technologies improved the information access to massive amounts of data in various manners. Also industrial domains benefit from semantic approaches. Information now can be accessed more precisely and is directly linked with related data. However, the actual support for humans to access suitable content at time is still in its infancy. In this paper, we motivate a number of requirements for extending current state-of-the-art information systems in order to support human-aware information access. The requirements are based on the experiences we made during the introduction of industrial information systems over the last years. © 2016, CEUR-WS. All rights reserved.

Semantic Search emerged as the new system paradigm in enterprise information systems. These information systems allow for the problem-oriented and context-aware access of relevant information. Ontologies, as a formal knowledge organization, represent the key component in these information systems, since they enable the semantic access to information. However, very few enterprises already can provide technical ontologies for information integration. The manual construction of such knowledge organizations is a time-consuming and error-prone process. In this paper, we present a novel approach that automatically constructs technical knowledge organizations. The approach is based on semantified document structures and constraints that allow for the simple adaptation to new enterprises and information content. © Springer International Publishing AG 2017.

To protect the health of human and environment, the European Union implemented the REACH regulation for chemical substances. REACH is an acronym for Registration, Evaluation, Authorization, and Restriction of Chemicals. Under REACH, the authorities have the task of assessing chemical substances, especially those that might pose a risk to human health or environment. The work under REACH is scientifically, technically and procedurally a complex and knowledge-intensive task that is jointly performed by the European Chemicals Agency and member state authorities in Europe. The assessment of substances under REACH conducted in the German Environment Agency is supported by the knowledge-based system KnowSEC, which is used for the screening, documentation, and decision support when working on chemical substances. The software KnowSEC integrates advanced semantic technologies and strong problem solving methods. It allows for the collaborative work on substances in the context of the European REACH regulation. We discuss the applied methods and process models and we report on experiences with the implementation and use of the system.

The paper describes a new approach of developing and maintaining state-of-the-art decision support systems. Such systems are able to capture the collaborative work on decision problems over time. Due to the complexity of large problem spaces a multi-modal knowledge representation is proposed. For the realization of a multi-modal knowledge base we integrate semantic technologies as a fundamental layer by combining the W3C ontologies PROV-O and SKOS. The approach is demonstrated by an implementation report of an industrially deployed decision support system. © 2015 Elsevier B.V.

The regular improvement and adaptation of an ontology is a key factor for the success of an ontology-based system. In this paper, we report on an ongoing project that aims for a methodology and tool for ontology development in a self-improving manner. The approach makes heavy use of methods known in natural language processing and information extraction. Copyright © 2014 by the paper's authors.

Today, large knowledge bases are developed collaboratively and in an incremental manner. Often the engineering starts with the collection and organization of informal elements, that are subsequently refined into explicit knowledge. Due to the size of knowledge bases and the collaborative setting, the analysis of the current development progress becomes an important issue. The results of that analysis usually steer the further development direction and efforts. In this paper, we introduce a graph-based representation of general knowledge bases, containing formal and informal knowledge.We use this representation to define general and tailored connectivity measures for knowledge bases. We briefly report on the application of these measures in an industrial case study. Copyright © 2014 by the paper's authors.

In this paper, we introduce the formal representation language DiaFlux, that is simple and easy to use on the one hand. On the other hand it allows for the definition of Computer-Interpretable Guidelines (CIGs), that can solve valuable tasks being executed in the clinical context. Further, we describe a wiki-driven development process using the stepwise formalization and allowing for almost self-acquisition by the domain specialists. The applicability of the approach is demonstrated by a protocol for sepsis monitoring and treatment developed by a collaboration of clinicians. © 2012 Springer-Verlag.

Technical documentation is a special purpose content describing machines and plants with high complexity. The documentation covers operation, maintenance and repair of the technical artifacts. The high complexity of the machines yields a voluminous documentation, where it increasingly becomes difficult to find the relevant information for a given problem. The paper discusses the use of semantic technologies to organize the documentation on a syntactic and semantic level. Also, a scheme for the assessment of the maturity of existing documentation is proposed, that simplifies the application of semantic technologies. Copyright © 2015 by the papers authors.

KnowWE is a semantic wiki that provides the possibility to define and maintain ontologies and strong problem-solving knowledge. Recently, the ontology engineering capabilities of KnowWE were signifi- cantly extended. As with other ontology engineering tools, the support of ontology debugging during the development of ontologies is the deficient. We present an Ontology Debugger for KnowWE that is based on the delta debugging approach known from Software Engineering. KnowWE already provides possibilities to define test cases to be used with various knowledge representations. While reusing the existing testing capabilities we implemented a debugger that is able to identify failure-inducing statements between two revisions of an ontology.
